With our wet and windy climate, it's no wonder up to 10% of UK properties suffer from issues like mould, peeling wallpaper, and musty odours caused by excess moisture. Damp not only damages buildings, but it also aggravates health issues and ruins furniture and belongings. In this article, we'll look at how different construction materials can either encourage or prevent damp in our homes. You'll learn how to banish wet walls and create a drier, healthier indoor environment. With the right materials, you can give your property an edge against the damp! Causes of Damp Before we get into materials, let's quickly go over what causes damp. The main culprits are rainwater penetration, rising damp from the ground, condensation, and leaks from faulty pipes or overflowing gutters. Older homes with solid walls are particularly prone to damp issues. Damp leads to mould growth, which can aggravate allergies and asthma. Blocking Penetrating Rainwater When wind-driven rain seeps into your home, it brings dampness with it. Using water-resistant materials on the outer walls prevents rainwater penetration. Brick, stone, and rendered concrete blockwork do a decent job, but adding a waterproof coating makes them even more effective moisture barriers. Modern acrylic render is an ideal coating for exterior walls. It's flexible, breathable, and keeps out that pesky wind-driven rain. Replacing old or cracked render improves protection too. Installing a damp-proof course between the render and wall prevents rising damp as well. Managing Rising Damp Rising... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/top-10-faqs-about-damp-problems-answered-by-experts-2/ - Categories: Damp Here are the top 10 frequently asked questions about damp problems, answered by us, the experts! What are the main causes of damp in homes? The most common causes of dampness in homes are rising damp, penetrating damp and condensation. Rising damp happens when moisture from the ground rises up into walls and floors due to capillary action in bricks and mortar. Penetrating damp occurs when water seeps in through cracks, leaky plumbing, windows or faulty flashing. Condensation arises when warm moist air meets a cold surface like windows or exterior walls, causing water droplets to form. Correct identification of the damp type is crucial for effective treatment. How can you tell if you have rising damp? Telltale signs of rising damp are a 'tide mark' of staining on walls up to 1 meter above the floor, salt deposits or crumbling plaster at the affected base. Moisture meter readings will be high at the base but gradually reduce higher up. What's the best way to treat rising damp? Installing a new chemical DPC injection to form an effective horizontal moisture barrier in walls is most effective. The damp plaster should be removed to at least 300mm above stained areas, before replastering. Correct preparation is vital for the DPC treatment to work properly. How can you prevent penetrating damp? Early inspection and maintenance helps minimise penetrating damp issues. Check for cracks in walls or damaged brickwork, and clear vegetation close to walls. Ensure there is proper flashing around windows, chimneys and... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/climate-change-and-damp-how-london-homes-are-affected/ - Categories: Damp Over the past few decades, climate change has led to warmer and wetter winters in the UK. This has contributed to an increase in damp and mould issues within London homes. Rising damp is a particular concern for many Londoners. What is Rising Damp? Rising damp is caused by rainwater soaking into the ground and being drawn up into the porous materials of walls and floors via capillary action. A functional damp proof course prevents this from happening, but many older properties either don’t have one or it has failed. As London has experienced more winter rainfall due to climate change, rising damp has become more prevalent. The main consequence of rising damp is the appearance of unwanted moisture in walls, which leads to black mould growth, crumbling plaster, rotten skirting boards and a musty smell. If left untreated, it can cause serious damage to the entire structure of a building. How Climate Change Worsens Rising Damp Wetter winters, more intense rainfall and warmer temperatures are all effects of climate change that exacerbate rising damp in London homes in the following ways: Increased winter precipitation saturates the ground to a higher level, providing more moisture to rise up through walls via capillary action. Warmer winters mean more of the rainfall ends up soaking into the ground rather than running off the surface. This adds to the moisture available for rising damp. Milder winters also mean walls stay damp for longer, as the drying potential is reduced.

While they often occur together, damp and mould have important differences. Understanding these key differences is essential for properly identifying and resolving moisture problems in a home. What is Damp? Damp is a general term for any unwanted moisture in a home. Sources of damp include rainwater penetration, rising damp from the ground, condensation, and water leaks from plumbing or appliances. The most common signs of damp are: Peeling, bubbling paint and wallpaper Stains or tide marks on walls and ceilings Musty odours and smells of mould Rotting wood and general deterioration Damp provides the ideal conditions for mould growth. However, dampness itself is not mould. What is Mould? Mould is a type of fungus that grows in damp, warm environments. In the home, it typically appears as black, green or grey spots or stains. Mould feeds on traces of natural matter like dust and skin cells. Mould requires moisture to grow. Common causes of household mould include: Excess moisture in the air and surfaces from condensation Leaks allowing water into the home Flooding or water damage to materials Mould releases spores that can cause health issues for some people such as coughs, wheezing, and irritated eyes. Extensive mould is a sign of an underlying moisture issue that requires remediation. Key Differences Between Damp and Mould While dampness and mould often coexist, understanding the differences between the two is important: Damp is moisture in or on surfaces, while... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/home-insurance-and-damp-what-every-homeowner-needs-to-know/ - Categories: Damp Repair, Damp Damp is a common problem faced by homeowners in the UK. Left untreated, it can lead to mould growth, damage to your possessions, and serious structural issues. With home insurance not covering damp, it's important for homeowners to understand the causes, signs, and solutions for dealing with damp. This article outlines everything you need to know as a homeowner about damp and your home insurance. Why Home Insurance Doesn't Cover Damp Standard home insurance policies do not cover damp. There are a few reasons for this: Damp is considered a maintenance issue that develops over time due to wear and tear or neglect. Insurers expect homeowners to proactively maintain their property. Pre-existing damp is not covered. When taking out a policy, you confirm your home is in good condition. Any damp issues present would breach this. The costs to treat damp can be high. As it's not caused by a sudden event, insurers see damp as foreseeable and exclude it. Damp can indicate broader structural issues not evident when you purchased your policy. Insurers may interpret damp as a sign you misrepresented the condition of your home. While inconvenient for homeowners, insurers see damp as preventable through vigilant maintenance. Repair costs therefore fall to the homeowner. How to Spot Signs of Damp Early detection is key to minimising damp damage. Look out for: Bubbling or peeling paint and wallpaper Mould on walls, ceilings or around windows A musty smell Rotting skirting boards and wooden furniture Staining along the bottom of... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/what-is-a-damp-proof-course-dpc-and-why-is-it-important/ - Categories: Damp, Independent Damp Surveying A Damp Proof Course (DPC) is a protective barrier that prevents moisture from the ground from rising up into the property. Installing an effective DPC is crucial for keeping a home free of damp and mould. This article will explain what a DPC is, the history of DPCs in the UK, why they are important, the different types available, and how they can fail. What is a Damp Proof Course? A DPC is a horizontal barrier made from waterproof material that is inserted into walls 150mm above ground level. It blocks moisture from the soil outside from being absorbed into the porous material of the walls, such as brick or stone. This stops damp from climbing up inside the walls via capillary action. Without a DPC, moisture could enter the property, causing issues like damp walls, mould growth, rotting skirting boards and structural damage. History of DPCs in the UK The origins of DPCs in the UK can be traced back to the early 1900s, when various materials like lead, asphalt and bitumen were used. However, they only started becoming widespread in the 1950s. Initially slate was a popular choice of DPC, but this rigid material can crack over time as the building settles, causing damp issues. Nowadays plastic DPC membranes made of materials like polyethylene are common. The invention of cavity walls in the 1920s also helped combat rising damp, as the gap between the inner and outer wall acts as a barrier. Why are DPCs Important? Installing an... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/damp-course-explained-everything-you-need-to-know/ - Categories: Damp A damp proof course (DPC) is a horizontal moisture barrier within walls designed to keep damp out. DPCs are typically made of strips of black plastic or bitumen material laid in the mortar joint about 150mm above ground level. During construction, building inspectors check DPC installation to ensure full overlap where strips join and proper integration with the floor membrane for a watertight seal. The existing DPC level also provides a fixed point of reference when taking measurements for extensions. What are Vertical DPCs? Vertical DPCs are installed in some cases to prevent damp transfer horizontally. These are often used where garden walls join the house walls. DPCs are also built into chimney bases and parapet walls to prevent downward moisture seepage into lofts and upper floors. Cavity trays with DPC materials are used over window and door openings. Timber windows and door frames may also have a DPC for extra protection. Why DPCs are Important for Preventing Damp DPCs became a legal requirement in 1875 because many construction materials like brick and concrete are porous. This porosity allows water to be absorbed from the ground upwards through capillary action. DPCs cut off this moisture source. Originally, DPCs were slate courses. Later materials included lead, bitumen and modern hydrophobic engineering bricks. It's rare for properly installed modern DPCs to fail and lead to damp issues. Older Homes Most at Risk of DPC Failure Older homes with solid walls are most prone to DPC failure and associated damp problems. Victorian houses... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/what-is-a-cavity-membrane-system-and-how-does-it-work/ - Categories: Damp, Water Damage If you have a damp cellar in your property, you'll know how frustrating it can be to have unusable space. Not only is dampness an inconvenience, it can also lead to health issues for you and your family. Persistent exposure to mould and mildew can exacerbate respiratory illnesses. The good news is that cavity membrane systems allow you to waterproof these areas and regain use of the space. This article will explain what a cavity membrane system is and how it works to keep cellars dry. What is a Cavity Membrane System? A cavity membrane system is a type of damp proofing designed for use in basements, cellars and vaults. It consists of a polyethylene studded membrane that is installed on all floors, walls and ceilings of the area to be waterproofed. The membrane has raised studs on one side that create an air gap between the membrane and the wall or floor. This gap allows moisture to drain down into a channel at the base of the wall and be directed into a sump chamber. The sump pump then pumps the water outside of the building. Cavity membrane systems can be installed in both existing and new build properties. They are ideal for creating additional living spaces in cellars. The installation process causes minimal disturbance to the rest of the property. How Does a Cavity Membrane System Work? Unlike tanking systems that aim to block moisture, cavity membrane systems are designed to allow moisture in behind the membrane where... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/types-of-damp-proof-courses-which-is-right-for-your-home/ - Categories: Damp Damp is a common problem in many UK homes, particularly older properties. If your house suffers from damp issues, installing a damp proof course could provide the solution. But with several types of damp proofing available, which method is best for your home? This guide examines the main damp proof course options to help you make the right choice. What Causes Damp in Houses? Moisture in homes usually comes from rain seeping in from outside or condensation forming inside. Common causes include: Poor ventilation trapping moisture indoors Leaking pipes, overflows or blocked gutters allowing water ingress Defective or inadequate damp proofing Poor pointing around windows and doors Too much damp encourages mould growth, causes unsightly stains and damage, and impacts indoor air quality. Stopping rising damp is key. Do You Need a Damp Proof Course? Signs your home needs a damp proof course: Visible tide marks on walls Bubbling or cracking paint or plaster Musty smells Condensation on windows If you have rising damp, your existing damp proof course may be missing or faulty. Even new builds can suffer if damp proofing wasn’t installed properly. Types of Damp Proof Courses Liquid Damp Proof Course Injection This involves drilling small holes into mortar courses, then injecting a silicone-based fluid. The fluid soaks into the bricks, creating a water-repellent barrier. The pros of this method are that it is very effective for solid walls and has a long lasting effect of over 20 years. The downsides are that the injection process can... --- - Published: 2025-03-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/rising-damp-signs-causes-and-prevention-tips/ - Categories: Damp Rising damp is a common nuisance that affects properties across the UK. Thankfully, there are ways to identify rising damp so steps can be taken to address the root causes. This article explores the tell-tale signs of rising damp, what causes it to occur and provides useful tips on how to prevent and treat it. What is Rising Damp? Rising damp occurs when ground moisture rises up into the floors and walls of a building. This moisture comes from rain and groundwater. If left untreated, rising damp can cause significant damage to the fabric of a building. Rot can develop in timber elements and mould growth can pose health risks for occupants. Thankfully, there are ways to identify and treat rising damp. Signs of Rising Damp Here are the tell-tale signs of rising damp to look out for: Tide marks - Horizontal lines appear on walls up to 1 metre above the floor. These stains indicate the height that moisture has reached. Crumbling and loose plaster - As moisture penetrates the plaster, salts dissolve and recrystallise, causing it to crumble and flake away from the wall. Peeling wallpaper - Wallpaper can bubble and peel away from damp walls as moisture soaks through. Musty smells - The dampness allows mould and fungi to breed, creating a musty smell. Rotting skirting boards - Skirting boards, wooden door frames and other timber components rot over time. What Causes Rising Damp? There are a few typical causes of rising damp: Lack of a damp... --- - Published: 2025-03-18 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/rising-damp-identifying-signs-causes-and-prevention-methods/ - Categories: Damp, Damp Repair There are several types of damp that attack UK properties and in this article, we take a look at rising damp, identify tell-tale signs and look at potential causes. We also focus on ways that you can prevent rising damp from damaging your home. What is rising damp? If the ground is wet, moisture can penetrate a building and over time, damp can rise up the walls, damaging brickwork, mortar and timber as it goes. If unnoticed, rising damp will compromise brickwork and mortar and moisture will seep into the plaster on interior walls and ceilings, causing thousands of pounds of damage. What causes rising damp? Every building should have a damp proof course fitted between the bricks just above ground level, which prevents rising damp. In older properties the DPC membrane can easily be damaged, which isn’t something you would notice and as time passes, damp will gradually rise up the walls. Identifying signs of rising damp The following are tell-tale signs that rising damp is present in your home: Tide marks on walls – Once rising damp takes hold of a structure, the interior walls and ceilings are often damp and there are tide marks visible. This could include damp patches, which is a sign that you need to contact London Damp Specialists and arrange for a damp survey. Peeling wallpaper – When damp gets into the walls, it causes wallpaper to peel away, as the adhesive becomes compromised. Bubbling paint – When damp attacks timber frames, it... --- - Published: 2025-03-15 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/rising-damp-causes-signs-effective-prevention/ - Categories: Damp Damp and mould are a serious threat to UK properties, especially in London and the south, where clay is present and that stops water from draining away. Rising damp specifically comes up from the ground and using a capillary action, moisture can rise up brickwork and masonry, causing damage to the building. Every structure should have a damp proof course, which is about 5mm in thickness and it is sandwiched between courses of bricks to prevent moisture crossing the barrier. What causes rising damp? Damp rises up walls if the damp proof course (DPC) is damaged or not present, hence the term ‘rising damp’; if the DPC is defective, it doesn’t take long for moisture to invade the building. Damp that enters a building from other locations is known as penetrating damp, rising damp comes from the ground. Victorian properties often have a damp issue because the DPC degrades and finally breaks down. There are several ways to deal with defective DPC; a popular solution is injectable DPC, which is a type of foam and when injected into a cavity wall, it prevents rising damp. Tell-tale signs of rising damp On the exterior walls, a sign of moss or mould growth is an indication that moisture is present within the material; if you find areas, take a screwdriver and poke at the bricks/mortar to see if it is crumbling and if so, you have defective DPC and that needs to be resolved before the damage is repaired. Interior signs of... --- - Published: 2025-03-12 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/different-types-of-damp-proof-courses-and-how-to-choose-the-right-one-for-your-home/ - Categories: Independent Damp Surveying We have always had unpredictable weather here in the UK and the last few years, we have seen a cloudy and wet climate, which means a greater risk of damage to properties, especially in London and the Home Counties. Damp and mould are a very real threat and in this short article, we take an in-depth look at the various types of damp proof courses and how to select the ones that are right for your London home. Physical damp proof course – Homes that were constructed pre-1970s would have a bitumen strip that is inserted between brickwork courses, typically close to the ground. About 5mm thick, this DPC membrane prevents moisture from rising up the walls and should it become damaged, damp issues would surely follow. Post 1970s DPC would be made from a form of plastic and is sandwiched between courses of brickwork, which protects the building from rising damp. Sheets of DPC membrane for walls – Typically used to damp proof basements, the membrane would be fitted to the walls, using studs to create a cavity between the substrate and the membrane, strips are overlapped and sealed with mastic or silicone, or large sheets are used to cover an entire wall and the layer is waterproofed. This is known as basement tanking and at London Damp Specialists, we offer an expert basement waterproofing service that comes with a full 30-year warranty. Cavity membrane for floors – The floor membrane is different to wall membrane and it contains... --- - Published: 2025-03-10 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/the-ultimate-guide-to-carrying-out-a-damp-inspection-in-your-london-home/ - Categories: Independent Damp Surveying You may have recently moved into an old property in London and you notice signs of damp that you hadn’t seen when viewing the property; all is not lost, however, as you can arrange for a certified damp surveyor, or you can follow our instructions and do your own damp inspection. Essential equipment The gear you will need includes the following: Torch – Essential to see in those dark corners in the loft and other locations where there is insufficient illumination. Order a rechargeable flashlight online and it can be stored in the car for emergencies. Screwdriver – Not to turn screws, rather to poke and prod brickwork, mortar and masonry, looking for signs of crumbling. If you happen to encounter moss growing on exterior surfaces, remove it and see what is underneath. Hygrometer – This device measures moisture in the air, which is a critical factor where damp is concerned. A reading higher than 60% is considered excessive and steps must be taken to reduce the amount of moisture in the air. Moisture meter – There are two types; pinned and pinless, with the prongs used to insert into materials to measure moisture content. The pinless variety can only measure surface moisture, so the pinned meter is preferable, as it can measure inside wood and plaster. Peephole camera – While not absolutely essential, a borescope camera helps you to get close up views of dark corners and under floorboards. They can be found online and are not too expensive;... --- - Published: 2025-03-09 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/understanding-cavity-membrane-systems-and-their-functionality/ - Categories: Damp, Damp Repair There are many ways to damp proof buildings and in this article, we take a look at cavity membrane systems, which are generally used in basements, cellars and any below-ground structure. How do cavity membrane systems work? There are 3 main components to a cavity membrane system, namely: Cavity membrane – Made from High Density Polyethylene (HDEP), the membrane has studs to create a cavity between the walls and the membrane. Water is then directed into the drainage channels on the floor, keeping the walls and floor dry. Drainage channels – Placed at the base of walls, these channels divert water to designated discharge points. Pump system and sump - The pump is located near the drainage channels and removes the water, sending it to the drainage system. The sump chamber holds the water until it is pumped clear of the building. Floor and wall membranes are different, with the floor membrane usually having a wider gap than wall membranes, which allows large volumes of water to escape the space. The cavity between the interior walls and the substrate should be large enough to accommodate water and if installed correctly, this should be sufficient to keep the interior dry. Basement tanking This term is used for basement or cellar waterproofing and a type C cavity membrane system is a very effective way to waterproof a basement or cellar. We do not recommend that you carry our basement tanking yourself, as it is specialised work that should be done by an... --- - Published: 2025-03-08 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/woodworm-dry-wet-rot-a-london-homeowners-guide/ - Categories: Damp Timber has long been the go-to material for construction, especially from the Victorian Era onwards, and while wood has many benefits, it is susceptible to woodworm and various forms of rot, which we outline in this short article. What is woodworm? There are numerous species of beetle that lays its eggs in timber here in the UK; the Common Furniture Beetle, Anobium Punctatum likes softwood such as pine and spruce, although it can infest species of hardwood; no timber is safe from this prolific beetle that has been around since time began. Other species include the Death Watch Beetle, a dark brown insect that burrows deep into wood and lays its eggs; tell-tale signs include small piles of dust next to the holes and if you spot these insects dead on the floor, there is a nest nearby. The House Longhorn Beetle is another UK inhabitant that might decide to set up home in your property; it likes oak and ash; while it is less common that the Common Furniture Beetle, the larvae can take as long as 10 years to fully develop, ending up 25mm long. The experts know the best treatments and can make short work of an operation. Dry rot Dry rot is a timber fungus that eats wood, causing it to lose its tensile strength and it can be from numerous fungi; a 4-stage process starts with microscopic spores that become airborne, which resemble a fine orange dust. If there is adequate moisture, the spores settle... --- - Published: 2025-03-05 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/damp-course-explained-a-comprehensive-overview/ - Categories: Damp, Damp Repair The damp climate we experience here in the UK can cause serious damp issues for property owners and every building should have a damp proof course that is normally sandwiched between brick courses near the ground level. If you are looking at the brickwork on the exterior of your home, you should see a thin black line between 2 courses of bricks, which is the damp proof course. Building regulations state that a DPC membrane must be included in every new build and we have been doing this since the late 19th century, when bitumen was used to prevent moisture rising up from the ground and attacking the exterior walls. Damp proof injection A damp proofing specialist in London offers DPC injection whereby a special foam is injected into a cavity wall through drilled holes. This is a highly effective way to prevent moisture from rising up a building and we at London Damp Specialists offer this service, which is one of many damp proofing services we perform on London properties. This is a more effective solution than using a DPC membrane and by filling the wall cavity, damp cannot rise from the ground. First, the damaged plaster is removed and the wall is prepared, then a series of 12mm holes are drilled at around 150mm from ground level. Then the DPC foam is pumped into the wall and when it reaches the level of the holes, plastic plugs are inserted; a scratch coat of plaster is applied, which is... --- - Published: 2025-03-04 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/basement-waterproofing-what-london-homeowners-need-to-know/ - Categories: Damp, Water Damage London has more basements and cellars that any other UK city; it has always been a thing to add underground living space in the capital to get the most out of a plot; then there was an explosion starting in the 1990s when wealthy residents commissioned stunning basements with several levels. Check out the Basement Wars documentary that outlines the potential for London properties to double their value and when you add these to the many Victorian cellars that are found in London homes, that is a huge market that requires basement waterproofing solutions. Included in the build A new build would incorporate a cavity drainage system that effectively waterproofs the ceilings, walls and floors, with a sump area and a pump to send water to the designated drainage outlets. These are complex systems and if installed by a professional basement tanking team, you effectively create a dry space. We at London Damp Specialists have all the solutions for new below-ground builds and what’s more, we guarantee our work for a full 30 years. Basement tanking A term that refers to basement waterproofing using water-resistant cement and screed that is applied to pre-treated surfaces. This is a multi-stage operation that requires planning and a survey to determine the best solution. A lot depends on the type of ground and whether there is already effective drainage; we can assess a site and provide an all-inclusive quote for basement tanking services.

One of the main threats to UK buildings is damp and every property should have a damp proof course, which is typically made from bitumen and is inserted between brick courses at ground level when the foundations are complete. How important is a damp proof course? Dampness in the ground will rise up the building, but only as far as the damp proof course, which would be inserted just above ground level. This course should continue around the building and should the course be damaged and compromised, damp will rise up the exterior walls and damage occurs. Older properties are more likely to suffer with a damaged DPC membrane (damp proof course) and regular damp inspections are advised. How long does a damp proof course last? A damp proof course should last at least 25 years, indeed, if the membrane is of good quality and has been installed correctly, it should last a lot longer than 25 years. It should be noted that it only takes a small portion of the damp proof course to be damaged for damp to rise up the walls, which would cause significant damage over time. A property that was build post 1970s would probably have a plastic damp proof course, which is stronger than bitumen and less likely to be compromised. Proactive strategies for preventing damp and... --- - Published: 2025-03-02 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/home-insurance-and-damp-critical-information-for-homeowners/ - Categories: Damp Repair, Damp We all have home insurance, or at least we should in order to have peace of mind, yet many UK homeowners have not read the small print and therefore, they are not quite sure what their home insurance actually covers. In this short article, we offer important information regarding home insurance and whether it covers damage caused by damp. Damage caused by damp Most home insurance policies actually cover damage that is caused by damp and moisture; if, for example, damp causes wallpaper or paint to peel off the wall, the insurance should cover replacing the wallpaper or paint, yet the policy would not cover damp repairs, which must be carried out before you can repaper the walls. In the event the DPC membrane is compromised, this will allow rising damp to climb the walls, and the cost of repairing the damp proof course would probably not be covered. Different types of damp There are numerous forms of damp, which are as follows: Rising damp – This is caused by a damaged damp proof course at ground level and damp can then rise up the external walls. Penetrating damp – Penetrating damp can affect any part of a building, from the roof to the foundations. Crumbling masonry and inferior mortar are common causes of penetrating damp, while blocked guttering and a leaking roof can also lead to penetrating damp. Condensation – Condensation forms when moisture forms on surfaces that have different temperatures. If the temperature outside is much colder than... --- - Published: 2025-03-01 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/the-many-moulds-that-attack-london-homes-an-overview/ - Categories: Damp, Water Damage We have a wet and dull climate here in the UK and that creates an ideal environment for mould and mildew to grow. Parts of London sit on a combination of clay and bedrock and heavy moisture content is usually the result; if the environment is right for fungal growth, any of the following could appear in your London home. Penicillium – Greenish-blue and white mould, which can grow on walls, ceilings and even fabric. Known to cause allergies and breathing problems, call in the professionals to deal with this fungus. Aspergillus – Typically green, brown or yellow, found on damp walls and window frames. A dank smell is usually present and this fungus can spread quickly in still and humid environments. Black mould – Stachybotrys is the official name; prolonged exposure to black mould can lead to serious respiratory disease. Commonly found in dark places with long-term damp, we recommend vacating the room(s) until we have finished the remedial work and the area is fungi-free. Cladosporium – Dark green or black mould found on damp surfaces; lack of ventilation helps this mould to replicate; a good airflow helps keep it in check. Alternaria – A fuzzy and fluffy texture, typically found in kitchens and bathrooms. Clean away visible mould with powerful cleaning agents and ventilate the room well. Chaetomium – A white, fluffy material that is found in wet and dark places; associated with heavy water damage, the damp issue needs to be fixed first, then cleaning and repainting... --- - Published: 2025-02-27 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/damp-vs-mould-key-differences-explained/ - Categories: Damp, Condensation Moisture levels are high in the UK, largely thanks to the wet climate we have, especially in London and the southeast. In this short article, we take an in-depth look at the key differences between damp and mould to help London homeowners gain a deeper understanding of moisture issues. What is damp? Dampness is cause by excessive moisture that eats away at brickwork, masonry, mortar, plaster and timber, which can cause significant damage to property. If you suspect that damp is present in your home, you can arrange for a qualified surveyor from London Damp Specialists to assess whether or not damp issues are affecting your property. Rising & penetrating damp These are the two types of damp and the difference is the source of the moisture; rising damp comes from the ground, while penetrating damp can affect a building at any location. Both forms of damp will penetrate building materials, causing a great deal of damage as it does. Mould Mould and mildew thrive in damp and humid conditions, especially window sills that have condensation forming on a regular basis. One sign that mould is present is a musky smell in the house and if you notice that, you need a damp proof specialist to assess the situation; mould growth can be found on walls, ceilings and timber window and door frames. Mould is actually a fungus that thrives in damp and humid environments and as a homeowner, you should keep your eyes open, looking for mould and mildew... --- - Published: 2025-02-25 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/damp-mould-timber-treatments-top-services-offered-by-a-london-damp-proof-specialist/ - Categories: Damp, Damp Repair If you are a London property owner, you already know about building maintenance and how important it is to maintain a property; in this short article, we take a look at the wide range of services we offer to London property owners. Damp surveys Early detection is obviously paramount when it comes to damp and mould; we offer the following damp inspections. Free damp inspection – A totally free service, if you would like a professional opinion regarding damp in your home, we offer a free damp assessment. Homebuyer damp survey – Designed for those buying or selling a property, this survey has 3 levels, namely 1,2 and 3. Level 1 is a close inspection of exterior and interior walls, floors and ceilings, while level 2 includes the above, plus a close inspection of all roof timbers. Level 3 goes one step deeper, using thermal imaging, moisture meters, humidity testing with a hygrometer and ventilation flow tests. Independent damp survey – Similar to the homebuyer survey, when you want a professional damp assessment report, the same 3 levels apply. Lab analysis – Samples of plaster are tested for moisture content. This is an add-on service for any of our regular surveys. When you commission a damp survey from London Damp Specialists, we issue a detailed written report within 24 hours of survey completion. We quote a competitive price for all our damp proofing and timber preservation treatments and we understand that time is of the essence regarding damp proofing; we... --- - Published: 2025-02-24 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/the-effects-of-climate-change-on-damp-in-london-homes/ - Categories: Damp, Condensation The weather in the UK has taken a turn for the worse; like it or not, we are currently facing a climate crisis, global warming is showing itself after decades of CO2 emissions. Sea levels are rising and we have had more than our fair share of rain and as for the Sun, we rarely get a glimpse these days! This wet climate means that damp, mould and mildew thrive and at London Damp Specialists, we pride ourselves on our ability to deliver accurate survey information and timely and effective damp proofing services. Rising & Penetrating Damp The difference between these two conditions is only that rising damp is a ground level issue, impacting walls with moisture coming from the ground. Penetrating damp can be at any location in a property, walls, ceilings and also the roof. Wet Ground If your home is situated on low ground, there is a high risk that damp will be a real threat, especially if you have a basement. We offer a comprehensive basement waterproofing service that seals the entire structure and furthermore, we issue a 30-year warranty on all our work. Indeed, basement tanking is commonly required in London properties, where it is popular to build below ground. Regular Roof Inspections As rainfall figures rise, this puts more pressure on a property’s roof; a series of heavy storms could, for example, cause several roof tiles to shift and if rainfall gets into a roof, this can cause thousands of pounds worth of damage.... --- - Published: 2025-02-22 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/how-to-carry-out-a-damp-survey-essential-information-from-professionals/ - Categories: Independent Damp Surveying You might be planning to buy a property in London, or you simply want to find out if damp is present in your home, whatever the reason, if you want to check a property for damp issues, we offer essential information in this short article. Equipment that you will need To effectively inspect your London home for damp and mould, you will need the following: Moisture meter – This device measures the moisture content in building materials and there are two types, namely pinned and pinless. The pinned variety allows you to measure moisture content in building materials such as timber and plaster; they can be sourced and purchased online. Humidity tester – A device that measures the amount of humidity in the air; a hygrometer is an important piece of kit that every damp surveyor would own. Flashlight – Necessary to illuminate dark corners, places where mould is likely to grow. Make sure you check every square inch of the loft, as damp can cause serious damage to roof timbers. Screwdriver – Used to scrape and prod exterior materials, looking for signs of damaged brickwork, masonry and timber. Ladders – An important aspect of inspecting a building is checking the roof, especially cleaning out the guttering; if the guttering becomes blocked, excess rainwater seeps down exterior walls, which can cause penetrating damp. Peephole camera – Also known as a borescope camera, this device allows you to get a close-up view of hard-to-reach places. Under floorboards, staircases and inside cupboards... --- - Published: 2025-02-21 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/top-10-faqs-about-damp-problems-answered-by-experts/ - Categories: Damp You asked, so we decided to select the best FAQs to help you gain a deeper understanding of damp issues and solutions. Q: What’s the difference between rising and penetrating damp? A: Damp penetrates by nature; rising means moisture from the ground, so to protect against rising damp, a damp proof course or DPC membrane would be added at ground level. Penetrating damp refers to moisture that enters a building at any location and treatment for both offers effective protection. Q: What is the best way to check for damp when buying a London property? A: If you are buying real estate in London, call London Damp Specialists on 020 8528 3864 or fill in the required fields on our website. Q: Is there a warranty on damp proofing services? A: London Damp Specialists is a family-owned business with a fantastic reputation; all work is fully guaranteed for 30 years. Q: Does the customer receive a report? A: The customer receives a detailed report within 24 hours of survey completion. Q: Do we have to move out of the home when the work is carried out? A: That depends on the extent (and location) of the problem area. Basement water proofing would not impact your occupancy of the home, you may need to vacate an area of your living space. Q: How long does a homeowner survey take to complete? A: An average family home can be surveyed within 2-3 hours. A detailed written report is submitted, usually with 24... --- - Published: 2025-02-20 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/climate-change-how-damp-impacts-london-homes/ - Categories: Damp, Damp Repair We don’t need reminding that our planet is in the midst of a climate crisis, the polar ice is melting at an alarming rate according to the scientists and here in London, we rarely get to see the Sun and rainfall is higher than it’s ever been. This is a recipe for dampness to invade a building and homeowners need to be vigilant. What does this mean for London property and damp? There are layers of clay in the southern part of the UK that hold water and that means damp ground, with moisture that can rise up brick and masonry structures, causing a lot of damage. Moisture penetration has long been an issue for London properties and in this short article, we highlight the threats that damp brings. Rising damp Damp that comes from the ground climbs buildings by a capillary action, impacting brickwork, mortar and timber; buildings have a damp proof course between courses of bricks and this prevents moisture from passing this membrane. If the DPC membrane is compromised in any way, moisture moves up the wall. Penetrating damp This kind of damp can come from any direction, especially the roof and exterior walls; regular inspections are advised if you want to detect damp early, as it can spread quickly through a building. Wet weather is ideal for damp and homeowners need to be proactive when it comes to moisture protection; if you are planning to buy property in London, we offer a homebuyer damp survey, which... --- - Published: 2025-02-19 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/understanding-the-role-of-building-materials-in-damp-prevention/ - Categories: Damp The inclement weather we have here in the UK can wreak havoc on properties; cloud cover seems the norm these days and we get more than our fair share of rain, especially in London and the southern part of the British Isles. Damp causes serious damage to buildings and in this article, we take an in-depth look at the role of building materials in the prevention of damp. Penetrating damp Moisture, by its very nature, penetrates building materials such as brickwork, mortar, masonry, plaster and timber, which can lead to significant damage to a structure. If moisture gets into any of these materials, it will penetrate, or in the case of ground damp, it will rise up walls, causing damage as it spreads. Perhaps the homeowner’s worst enemy, damp can quickly cause structural damage that would cost thousands of pounds to repair. Damp proof materials These are substances with special qualities that are designed to resist moisture penetration; here are a few materials that are used to protect buildings from moisture. Plastic/PVC - Sheets of plastic can be used to create a barrier to prevent moisture seeping into a building. Bitumen – This is a by-product of petroleum distillation that is commonly used to damp proof a structure. It is usually applied as a coating and when it dries, the material cannot be penetrated by moisture. Damp proof paint – A special paint that is applied to surfaces to prevent damp from penetrating a building. Bitumen felt – This material... --- - Published: 2025-02-18 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/basement-tanking-waterproofing-explained/ - Categories: Damp Many London homes have a basement; it was definitely fashionable in the early 20th century to build below ground living space and as we can’t build higher, many property owners choose to build underground living space. London has more basements than any other UK city and because this part of the country has a clay base, water can be a serious issue. Water retention is very high in some areas and perhaps building basements is not possible in certain locations. Cavity Drainage Systems Cavity drainage systems are a very effective way to control water in a basement; studded wall membrane is fixed to the walls to create a cavity behind the wall and the water drains into channels under the floor and is directed into a sump area, then the water is pumped to designated drainage points. This system is used when regular basement tanking is inadequate, as it is able to deal with water that accumulates in a basement. The best time to install a cavity drainage system is during the build, although a system can be installed at any time; the basement needs to be cleared during the installation. Main Components of a Cavity Drainage Systems The main components are as follows: Cavity membrane – Special material with studs to keep the membrane away from the wall, creating a cavity that holds water. Floor membrane – Raised slightly above the floor, there are channels to hold draining water that comes from behind the wall cavities. Sump area and... --- - Published: 2025-02-17 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/signs-of-serious-damp-issues-that-demand-a-professional-damp-proofing-specialist/ - Categories: Damp The wet weather we are experiencing in the UK never seems to end and this is certainly bad news for London homeowners, what with clay-based ground that holds water, which can cause serious damp issues. Serious damp problems need professional treatment, and with that in mind, here are a few signs that your home is under attack by moisture and you need professional damp proofing in London. Visible damp patches on interior walls and ceilings This is a sure sign that damp has taken hold of your home; for damp to seep into the interior plaster, there must be a significant leak. London Damp Specialists have qualified and experienced surveyors that can identify the cause of serious damp problems and our teams of damp proofing specialists are ready for anything. Work needs to commence sooner rather than later and when we issue a quote, it is all inclusive, plus we guarantee our work for a full 30 years. Black mould growth Black mould presents a serious health hazard and prolonged exposure can lead to serious respiratory and the sooner you call in the experts, the better. Black mould can spread quickly and it is usually accompanied by a musky smell in the house; it might be that part of the property needs to be vacated until the work is completed, as safety is an issue. Rotting roof timbers A major roof leak that is unaddressed could lead to serious wet rot that attacks rafters and joists; replacing roof timbers is... --- - Published: 2025-02-16 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/a-guide-to-choosing-the-right-damp-specialist-in-london/ - Categories: Damp, Independent Damp Surveying London property owners are as much into maintenance as those in other parts of the UK and as you would expect, damp is at the forefront of their mind, thanks to the dull, wet weather that seems to have parked itself permanently over the British Isles.

Rising damp can cause serious damage to brickwork, cement and timber; early detection equates to inexpensive repairs, which is part of our homebuyer damp survey. Penetrating damp, mould, mildew and condensation can also wreak havoc in buildings and early detection is critical. Homebuyer Damp Survey This survey is designed for those who are looking to buy or sell; for the buyer, it makes sense to investigate damp prior to making an offer and a seller can show the survey report to potential buyers. There are 3 levels to the homebuyer damp survey: Level 1: Inspect all interior and exterior walls, floors and ceilings, checking for signs of damp or mould. Level 2: All actions in level 1 plus an examination of all timber including loft timbers, joists and rafters. Level 3: All of levels 1 & 2, plus the use of thermal imagery, humidity testing, borescope camera, drome imagery for the roof and ventilation flow tests. There is an additional service to analyse plaster samples for moisture content for an extra cost. Level 3 is a comprehensive damp survey that covers the entire property, while level 1 is primarily an introductory survey. Keeping Repair Costs Low Early detection keeps remedial costs down to an acceptable level and regular inspections is a proactive approach.

Timber-related issues Timber can be damaged by; Woodworm – Boring wood beetle larvae, which can cause serious damage, small holes and mounds of wood dust signify the presence of woodworm. Dry rot – A fungal infection that leaves wood brittle and easy to break. It thrives in a dry, still atmosphere. We provide effective dry rot treatment. Wet rot – Excessive moisture breaks down timber and it loses its form and weakens. If unchecked, wet rot can cause structural damage that would cost thousands of pounds to fix. Termites – There are several species that can invade wood in the UK, timber can be treated to protect against insect infestation. We recommend a damp inspection every year and part of that involves inspecting all timber for the above conditions. Tell-tale signs of timber issues Things to look for include: Splintered and cracked wood – Signs of dry rot, especially at the ends of timber lengths. Spongy timber – A sign of high moisture content. Woodworm holes and dust mounds – Signs of beetle larvae. Discolouration – Darker patches indicate high moisture content. Mould growth – Typically found in dark corners of the loft.

As we live in such a wet and drizzly place, it is no surprise that moisture is a homeowner’s number one enemy, and with that in mind, here is our guide to carrying out a damp survey. Tools and equipment To carry out a damp survey, you will need the following: Flashlight – To get a close up of those hard-to-reach places, you need a powerful flashlight. If you don’t have one, there are some cool rechargeable torches online that can be used for many things. Moisture meter – Not absolutely essential, but it is nice to be able to measure the moisture content in plaster and timber. The pin moisture meter is preferable to the pinless variety; they can be found online and you will find it useful over the years. Screwdriver – Used to prod and poke brick, mortar and masonry, looking for signs of penetrating damp. Ladder – In order to check the upper levels of exterior walls, an aluminium ladder is invaluable; if you are comfortable with heights, check the roof guttering for blockages and look for missing roof shingles. Borescope camera – Again, not essential, but a peephole camera can look under floorboards and in the loft. Professional surveyors use this device and it... --- - Published: 2025-02-12 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/london-weather-and-how-damp-impacts-houses/ - Categories: Condensation, Damp, Damp Repair Those who are old enough to have grown up children will remember those blazing summers that seemed to be never-ending; fast forward and we never see the sun; it might be global warming or even geo-engineering! Whatever the reason, the cold, wet weather seems to be parked right over the British Isles and aside from making us all feel miserable, the damp atmosphere enables moisture and mould to invade buildings. Rising damp We have teams of damp proofing teams in London, and they are busy waterproofing basements and damp proofing homes. Rising damp is the number one issue we face; moisture that is drawn up from the ground and this usually due to a defective DPC membrane, usually in older properties and we can use a DPC injection to protect the house from rising damp. Penetrating damp Simply put, this is moisture entering the building by any means; it might be a leaking roof, or compromised brickwork, moisture moves through materials with a capillary action, penetrating masonry, mortar, timber and render. Signs include damp patches on walls or ceilings, a musky smell in the house is an indication of mould and mildew and we happen to specialise in dealing with penetrating damp proofing in London, using a range of treatments.

While damp can be an issue at any time of the year, winter is by far the worst season and in this short article, we outline damp prevention strategies that you can employ to keep your home dry in the winter months. Roof inspection – A leaking roof will surely lead to water entering the internal roof structure, which damages timber joists and rafters; excessive water will eventually run down to the upstairs ceilings, causing damp patches to appear on plaster, peeling paint and wallpaper in the process. If you are not inclined to climb on the roof, contact a local roofing contractor to carry out a detailed roof inspection and clean out the guttering. Loft inspection – It is important to carry out a loft inspection to check the timber joists and rafters for damp damage, woodworm, wet and dry rot. Take a powerful flashlight and scan all areas in the loft; take extra care where you tread, do not step between the roof joists as you could end up falling through into a bedroom!

Some might say that damp is a silent assassin, it can move through a building and if not recognised and addressed, thousands of pounds worth of damage can be the result. The importance of early detection Time is everything when it comes to treating damp and mould issues; the sooner a problem is found, the cheaper the repairs will be. At London Damp Specialists, we offer a homebuyer survey that accurately determines if damp or mould is present in a building; this survey is designed for those who are planning to buy or sell a property and would like to check whether the building is free from damp problems. Rising damp Rising damp is moisture that comes up from the ground; every building should have a damp proof course that is sandwiched between courses of brickwork, which prevents moisture from attacking the structure. This damp proof course can be damaged or compromised, especially in older properties and should this occur, moisture will gradually rise up the walls, causing damage as it permeates brickwork, cement and timber. We offer a damp proof injection treatment that stops damp from rising up walls and when we carry out such work, we issue an unconditional 30-year guarantee.

Condensation is a common issue in a damp environment and in this short article, we offer a few great tips on how to prevent condensation and keep your home dry. Generate a good airflow throughout the house – Opening a few windows removes stale air and also dries things out considerably; this isn’t something you would want to do in cold weather, but if you do this a few times a week, that should remove most of the moisture in the air to give you a condensation solution. Install extractor fans in the bathroom and kitchen – When there is a build-up of condensation when taking a hot bath or shower, turn on the fan, which should remove the excess moisture; the same goes for cooking in the kitchen and keep the doors closed until the moisture has been removed. If you have an extractor in the canopy, make good use of it when cooking and keep kitchen doors closed until the excess moisture has dissipated. Turning on ceiling fans is another way to create an airflow, which is something to do in the summer, coupled with opening doors and windows. Invest in a portable dehumidifier – This can be wheeled into any room and turned on until all moisture is removed. Drying out the air is a cost-effective way to prevent condensation forming... --- - Published: 2025-02-07 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/top-5-causes-of-damp-in-london-properties-prevention-strategies/ - Categories: Damp If you asked any UK citizen what they would change if they could, most would say the climate; the UK has damp and drizzly weather and that is a serious threat to properties in London. In this short article, we take a look at the top 5 causes of damp and strategies for prevention. Leaking roof – Roof leaks are probably the number one cause of damp in London homes; all it takes is a couple of missing or broken roof tiles and a heavy bout of rain to cause serious damage to the internal roof timbers. You should inspect your roof at least twice a year and any issues need to be sorted in a timely fashion, before damage occurs. A loft inspection would reveal any leaks and you should check for timber damage in joists and rafters. Defective damp proof course – Known simply as DPC, this is made from either bitumen or a heavy-grade plastic and it is put between layers of bricks to stop moisture coming into contact with anything above the DPC line. In the event this is compromised, rising damp is a very real threat. One common solution is DPC injection, which is a cost-effective way to protect a property from rising damp. Excessive condensation – Condensation is formed when two extreme temperatures meet and it normally occurs on the windows, although it can form on walls. Timber can easily be damaged if a home has condensation issues and you should wipe up before... --- - Published: 2025-02-06 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/how-to-do-a-diy-damp-inspection-the-necessary-tools-and-techniques-that-you-need/ - Categories: Damp, Maintenance If you are a property owner in the UK, maintenance should always be at the forefront of your mind and damp is a serious threat, largely due to the wet climate we have in Great Britain.

Moisture meter – There are two types of moisture meter, pinned and pinless, the pinned variety enables you to insert the probes into plaster and other materials to determine the presence of moisture. At London Damp Specialists, our damp surveyors carry both moisture meters, along with many other high-tech devices to help them identify moisture, mould and mildew. Humidity meter - This is a device that accurately measures the amount of moisture in the air; the line is at 65%, more and you have a moisture issue in your home. Ventilation is important in a damp environment and you can generate an airflow by opening a few windows; mould or mildew might be present, which can be hazardous to you and your family’s health. Screwdriver – A large screwdriver can be used to check whether exterior walls have been compromised by damp. Mortar, brickwork and rendering can all be damaged by rising and penetrating damp and scraping materials can reveal issues. Flashlight – Of course, you need to illuminate those dark corners in order to carry out a thorough inspection, so... --- - Published: 2025-02-05 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/5-warning-signs-of-damp-to-look-for-in-your-home/ - Categories: Damp, Condensation Attention all London homeowners, damp and mould are very real threats to your property; the wet and drizzly climate we have to endure in the UK is an ideal environment for damp and mould to thrive.

Rising and penetrating damp, condensation, woodworm and dry rot are all a very real threat, and with that in mind, here are a few tips to prevent seasonal damp damaging your home. Winter dampness – As you would expect, damp is more likely to be an issue in the winter months, due to the cold and musky weather. You should use your central heating to heat the whole house, as this dries out the moisture in the air; you might be reluctant to heat rooms that are not in use, yet a few hours 2-3 times a week will help prevent the onset of damp. Generate a good airflow – Damp and mould thrive in a still and humid environment, which is why good ventilation is so important. You can use natural ventilation by opening a few windows, or the use of extractor fans installed in the right locations. This is equally important all times of the year, especially in the summer when temperatures rise. Commission a damp survey in spring – We at London Damp Specialists are extremely busy after the winter as London homeowners book a damp and mould survey for an accurate assessment of damp and mould in their home. Our homebuyer damp survey is ideal; it comes in 3 levels, depending on the extent of the survey, plus there is an... --- - Published: 2025-02-01 - Modified: 2025-03-21 - URL: https://londondampspecialists.com/blog/uk-homeowners-tell-tale-signs-that-you-need-to-call-in-a-damp-specialist/ - Categories: Damp, Damp Repair If you are a UK property owner, you already know how important building maintenance is, and damp is a very real threat. The best way to invite moisture into your home is to do nothing, and with that in mind, here are a few tell-tale signs that you need to call in London Damp Specialists. Condensation – One of the biggest enemies of UK property owners, condensation forms on surfaces when the air is moist, typically on the inner window panes, where warmth meets cold air. If the only place condensation forms is on the window glass, that doesn’t mean you have damp issues; replacing the windows with double-glazed units will remove condensation completely. If, however, condensation forms on walls or timber frames, this means the air is humid and remedial work is needed. Crumbling masonry/mortar - If damp is present in exterior walls, you might notice crumbling mortar or brickwork; this can be caused by moisture rising up from the ground, which means the damp proof course is compromised. Another likely cause is blocked guttering, which sends excess rainwater running down the exterior walls. Damp patches on interior walls and ceilings – Check every room and if you notice tide marks or damp patches on plaster, moisture is getting into your home. Of course, if there are damp patches, you need to identify the source of the moisture, which is where we at London Damp Specialists come in. Musky odour – If you notice a musky smell in the... --- - Published: 2025-01-30 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/cost-effective-solutions-for-damp-issues-what-you-need-to-know/ - Categories: Damp If you are a London property owner, you probably are aware that moisture is a very real threat to your home; the UK climate is generally damp and buildings must be protected with damp proofing services. We have been building structures for millennia and one thing we have learned is that moisture rises from the ground, causing bricks and mortar to be compromised. Here are a few cost-effective ways to prevent damp and mould in your home. Generate an airflow – Good ventilation prevents mould from forming and generally dries out the air. You can this by opening windows in the right locations and leaving interior doors open; install a few small extractor fans, one in the kitchen and one in the bathroom; they can be reversed so you can remove condensation quickly with extraction. Clean out roof guttering – Imagine this scenario, wet leaves clog the guttering and a few heavy storms cause rainwater to gush down the exterior walls. While doing that, inspect the roof, checking that there are no roof tiles missing and that everything is in good order. Heat the whole house – We understand that you would not want to waste expensive energy to heat areas of the house that are not being used, but if the air is damp, heat dries it out. Some homeowners use a portable space heater to warm up rooms that never get used. Inspect timber window frames, as woodworm can take hold, as can wet and dry rot.

Some areas of London experience a wet mist in the early mornings and this cam impact a building in many ways; a damp space with no ventilation is a breeding ground for mould and mildew, such is the important of a good airflow. Natural ventilation Opening windows throughout the house creates airflow that will clear the air and dry it out somewhat; do this on a daily basis in the cold months, while in summer, leave windows open when the house is occupied. Open sliding patio doors and all interior doors and prop the front door open which should generate a flow of fresh air, removing the moisture in the process. This is also a condensation solution and a constant flow of air will reduce the moisture in the air. Mechanical ventilation Installing extractor fans in all the right places gives you a controllable way to ventilate the interior; essential for kitchens and bathrooms, small extractors can be fitted into windows, allowing you to expel or draw air in. If you happen to notice a musky smell in the house, damp and mould are likely to be present. Invisible spores Mould replicates by releasing invisible spores that land on surfaces and start creating a settlement; ventilation removes these tiny pathogens, making it much harder for mould to take hold. If you have mould in... --- - Published: 2025-01-28 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/attention-london-homeowners-how-to-check-for-damp-mould/ - Categories: Damp, Damp Repair London and the south of England has its fair share of rain, add to that the fact that we never see the Sun these days and you have the ideal conditions for damp to attack buildings. As a homeowner, you should be vigilant when it comes to building maintenance and in this short article, we offer a few tips on how best to inspect your home for damp and mould. Interior walls & ceilings –A leaking roof will lead to water penetrating the interior structure and if left unaddressed, you will find damp patches and tide marks on walls and ceilings. Check every room and should you find signs of moisture, call London Damp Specialists and we will send a surveyor to inspect the property. Exterior walls – Close to ground level, there should be a damp proof course (DPC) between brick courses and if this is damaged, damp can penetrate up the walls. This is a gradual process and early intervention minimises damage; if you don’t spot this, further damage will be the result. Moss growth is a bad sign; take a screwdriver and poke the mortar, if it crumbles, you have a damp issues. Be proactive – You can make sure the home is well-ventilated, this reduces moisture in the air and even in the winter, it is wise to open a few windows for at least 30 minutes. Sill, damp air is the ideal environment for mould and mildew, which can cause serious respiratory conditions.

Damp has always been a threat to UK properties and when purchasing a home in London, a damp inspection is a must! Older London properties make good use of timber, which is susceptible to moisture penetration and that starts a reaction that leads to mould and dry rot. What does a damp survey entail? At London Damp Specialists, we offer a homebuyer damp survey, a thorough inspection of the building at every level from floor to roof that would reveal any moisture issues. Our certified damp surveyors use thermal imaging and moisture meters that can accurately measure moisture content in plaster and brick and you receive a detailed report the following day. Timber inspections All timber structures are closely inspected, looking for woodworm, wet and dry rot; if moisture is present, the surveyor can identify the source and repairs can be scheduled. The internal roof structure is checked; protective coatings can be applied and, in some cases, rafters or joists have to be replaced. Rising damp Moist ground means damp will impact the house and with a DPC membrane sandwiched between the lower courses of brickwork. Homes built pre-1980s would probably have a bitumen strip inserted into the brickwork, which stops damp from rising, while newer properties would have a special plastic DPC membrane,... --- - Published: 2025-01-27 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/the-ultimate-guide-to-the-various-types-of-damp-the-importance-of-inspections/ - Categories: Damp, Independent Damp Surveying We have a very unpredictable climate here in the UK, with lots of drizzle and cloudy days and that can mean a very real threat to buildings in the form of damp. In this short blog, we take an in-depth look at the different forms of damp that can attack your home. Rising damp – Moisture that comes from the ground can rise up through brickwork and masonry; every structure should have a damp proof course, or DPC membrane between courses of bricks, at or very near ground level. If the DPC is damaged or compromised, damp will gradually climb the exterior walls. You should regularly inspect your exterior walls at ground level, looking for crumbling mortar and render and if you notice signs of damp, call London Damp Specialists. Penetrating damp – This is moisture that enters the building from any location other than the ground. Water entering a leaking roof can cause a host of serious issues, with damp affecting joists and rafters. You should inspect your loft on a regular basis and take note of any signs of damp. Water tanks installed in the loft can spring a leak and this can lead to damp patches on upstairs ceilings. Condensation – Condensation forms when moisture turns to liquid form; when two extreme temperatures meet on a window pane, condensation forms on the inside and this needs to be wiped with a dry cloth before it damages timber and plaster. Ventilation is a critical aspect to reduce the... --- - Published: 2025-01-26 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/damp-proofing-specialists-in-london-what-we-do/ - Categories: Damp Many would agree that the British climate is far from ideal and the last few years has seen an increase in rainfall, which is likely due to global warming. Endless days of damp and humid weather create the perfect environment for moisture to penetrate buildings; some areas are waterlogged and low elevations contain a lot of moisture. London and the southeast have its fair share of damp issues – days without seeing a glimpse of the Sun is a recipe for moisture penetration – and we specialise in moisture control. Our services Damp surveys - Damp surveys are essential for those looking to purchase real estate in London; structural integrity cannot be assumed, a few coats of paint can hide timber rot, while damp can rise from the ground and climb up a structure. We offer a homebuyer damp survey that would reveal any moisture issues, plus we quote for remedial work that needs to be done. You might be selling your home due to work relocation and in such a saturated market, having a damp-free certificate is a great selling point. Basement tanking – Whether under construction or an existing structure, basement tanking in London is a comprehensive sealing of walls, ceilings and floors using Sika rendering. Each layer is allowed to dry out, then a new one is applied, increasing the seal; a cost-effective way to keep the space dry, whether a car park or wine cellar, we can ensure you have zero damp and moisture problems.

London real estate is very expensive and when you can’t build up or to the side, the only way to increase your living space is to build an underground room, which brings with it many challenges, not least keeping moisture and water at bay. In this short article, we take a look at basement tanking and Sika rendering to help you gain a deeper understanding of how to waterproof a basement. Common basement waterproofing systems Popular basement tanking solutions include the following: Cavity drainage system If regular tanking (waterproofing the walls) is not going to keep the interior dry, then a cavity drainage system is the way to go. The system has 3 main components; textured membrane, floor drainage channels and a sump area with a pump that directs the water to designated drainage locations. The membrane is studded to create a cavity behind the walls, which becomes a sealed area to contain water. Basement tanking A very effective way to waterproof a basement is to apply Sika rendering, which is a water-resistant cement that can be applied to walls and ceilings, effectively creating a waterproofed square enclosure. This is the most common solution for basement tanking in London; the ideal situation is to waterproof the basement when it is being built, yet many of our projects involve waterproofing an existing structure.

As a homeowner, it is your responsibility to maintain the building and the damp climate we have in the UK poses a very real threat to every structure, regardless of the materials used in its construction. Regular damp inspections Most people are not that observant when pottering around their home and tell-tale signs of damp and mould might go unnoticed. Once moisture gets into a building, it gradually penetrates the walls and causes damp to damage plaster and a damp and humid atmosphere can cause mould and mildew. Regular damp inspections give you a heads-up if moisture is present in the building and that can save you thousands of pounds in repair bills. Tell-tale signs of damp and mould The following are sure signs that you have moisture issues in your home: Excess condensation on windows – Condensation forms on the inner surface of windows when there are extreme temperature differences. It can also form on window frames and sills and should be wiped away with a dry cloth. After a hot bath or shower, open the bathroom windows to dissipate the condensation and keep the door closed to prevent moisture getting to other areas. Damp patches on interior walls and ceilings – Regularly check all rooms, looking for damp patches and tide marks.

Known as basement tanking, there are several ways to keep an underground space dry, with the most common being a cavity drainage system. What is a cavity drainage system? A type C cavity drainage system comprises of 3 main components, which are as follows: Cavity drain membrane – Typically made from high density polyethylene, there are studs fitted to create a wall cavity, an essential gap between the interior walls and the substrate. Water that enters this cavity is then channelled into a floor channel, where it is pumped into the drains. Drainage channels – Located at the bottom of the wall cavity membrane, the drainage channels direct water into the sump area. Sump area and pump – The sump area contains water, which is then pumped into designated discharge points. With the ceiling, walls and floor all protected by cavity membrane, the basement waterproofing system is comprehensive. It takes a few days to install a cavity drainage system and all items in the basement must be removed prior to the commencement of work. Benefits of cavity drainage system The benefits include: Reliable and efficient – A cavity drainage system offers a reliable and highly efficient solution that requires very little in the way of maintenance. Minimal surface preparation – Unlike traditional basement tanking, a cavity drainage system does not involve much in terms of surface preparation. Minimal stress on the structure – The... --- - Published: 2025-01-20 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/penetrating-damp-the-causes-signs-and-solutions/ - Categories: Damp There are two main forms of damp, rising and penetrating damp, and in this blog, we take an in-depth look at penetrating damp, the causes, signs and solutions. Rising damp vs penetrating damp, what is the difference? Rising damp comes from the ground, whereas penetrating damp can affect any area of a structure, both are equally destructive. If your roof is compromised, serious damage to joist and rafters could mean expensive repairs if timbers have to be replaced. Woodworm, dry and wet rot thrive in a moist setting and should you visit your loft and notice a musky odour, you should inspect the space looking for damp damage and timber decay. What causes penetrating damp? Penetrating damp can be the result of a leaking roof; all it takes is a few missing roof tiles and a heavy bout of rain to let rainwater into the internal roof structure. If the exterior brickwork is compromised, damp can enter and start to spread to the timber frames and interior walls, while blocked guttering is another cause of penetrating damp. Compromised mortar This is common with older properties, of which there are many in our capital and the wet climate means endless damp days; penetrating damp can slowly get a grip on a building and if you are not vigilant, by the time you find out, a lot of damage has already occurred. Tell-tale signs of penetrating damp Common signs of penetrating damp include the following: Tide marks on walls and ceilings Damp... --- - Published: 2023-09-09 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/common-signs-and-symptoms-of-rising-damp-in-walls/ - Categories: Damp, Damp Repair Rising damp, though some people think it is a myth, is a common problem in households across the country. It has many warning signs and tell-tale symptoms, so in theory, it should be fairly easy to notice. However, it can go unchecked for long periods when building owners don’t realise what they are looking at. This guide aims to inform about the common signs in walls so that no problem is left untreated. What Is Rising Damp? Rising damp is water that comes up from the ground and infiltrates a property. It is only ever found on the ground floor. Rising damp tends to reach around a metre in height, but it can go higher in rare cases. It differs from penetrating damp. It can come in at any point and affect any area of the room. So, how do you know if you have a rising damp issue in your house or property? Damp Smell The biggest clue will always be the odour of a room. This smell is distinct and smells like standing water. When rising damp takes hold, there will always be a smell that comes with it. Walking into a room, the smell will be stronger, but it is typically noticed throughout a house where there are impacted areas. While the smell is unpleasant, it should go away if you invest in the right treatment at the right time. Water Marks On The Wall Aside from the smell, there will be noticeable water marks coming up... --- - Published: 2023-09-06 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/common-signs-and-symptoms-of-penetrating-damp-in-buildings/ - Categories: Damp, Damp Repair When you think of a building – whether it’s a cosy home or a towering skyscraper – you imagine strength and resilience. However, despite the sturdiness of its structure, every building has its vulnerabilities, one of which is the risk of damp. Among the various types of dampness that can affect a building, penetrating damp is particularly troublesome. It enters structures horizontally, usually from the external environment. Recognising the signs and addressing the issue promptly can save you both time and money. What is Penetrating Damp? Penetrating damp, often referred to as lateral damp, is a moisture issue that plagues both residential and commercial buildings. Unlike the rising damp which makes its way upwards from the ground, penetrating damp occurs when water infiltrates the structure from the outside, moving horizontally through the walls, roof, or other external surfaces. The root causes of penetrating damp are varied, but they typically stem from a range of external factors: Weather conditions: Prolonged periods of heavy rain, especially when accompanied by strong winds, can force water into even the tiniest of cracks or gaps in a building’s exterior. Faulty building exteriors: Over time, construction materials deteriorate. Bricks can become porous, and mortar might erode. When this happens, water can easily seep into the building. Compromised roofing: Loose tiles, damaged flashing, or faulty roof joints can allow water to penetrate, leading to damp issues in the upper parts of the building. Poorly sealed windows and doors: Gaps or defects in the seals around windows and... --- - Published: 2023-09-04 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/diagnosing-and-treating-penetrating-damp-in-historic-buildings/ - Categories: Damp, Damp Repair Penetrating damp refers to moisture that penetrates a building through the roof, walls and below the ground. It is a serious concern in historic buildings because it can destroy their fabric, including the ceilings, walls, and any timber used in their structure. Although it can affect any building, older buildings that have not been maintained over the years are at a higher risk due to deterioration. Modern buildings can also suffer from this issue due to poor workmanship and defective downpipes, gutters, tiles, and renderings. If you are concerned about penetrating damp in a historic building, here’s how to diagnose the issue and rectify it if it is present. Why Does it Affect Historic Buildings More? Older buildings have several features that make them more susceptible to penetrating dampness. They often do not have a cavity but use solid wall construction techniques. Proper cavity walls drain water through what are known as weep holes. However, penetrating damp can still occur in historic buildings with proper cavities if the insulation is not installed properly if the cavities are obstructed or were filled incorrectly, and if the wall ties were installed incorrectly. Some walls also become porous over time, with the issue getting worse the longer a building stands. Sufficiently porous walls will lead to penetrating damp. Diagnosing Penetrating Damp Penetrating damp will typically show up as a patch on a wall, floor, or ceiling, a visual indicator you have an issue you should deal with. Such patches cause local dampness that... --- - Published: 2023-08-31 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/waterproofing-strategies-for-basement-extensions-in-london/ - Categories: Damp, Damp Repair Do you want more space in your home? If you have a basement, you can convert it into liveable or usable space to add more space to your home. There are varying levels of conversions, from simple to elaborate ones, depending on how much space you have, your budget, and other factors. Even though it may seem like a project without too many complications, there are several things you need to deal with before doing a basement conversion. One of these things is to waterproof the area. Because they lie below the ground, basements are typically damp, which introduces issues such as rising and penetrating damp and the possibility of mould growth. If you want to convert your basement, here are some of the best strategies to waterproof and keep it dry. Do a Survey First Before looking at the different basement waterproofing strategies you could use, you should first find the source of moisture in your basement. Each home and basement is different, so a solution that works on one might not work on another. A waterproofing specialist can complete the survey for you, and they may even let you know of additional issues that you need to take care of before starting the conversion. For example, they may notice signs that the basement walls will crack and cause moisture issues in the future. They can provide solutions for these and other issues.

Sometimes, the main aim is an easier application, but improved performance and lower maintenance are also top reasons for this. Render is one product that is often improved with each new development. However, the technical terminology that you might come across when looking for a type of render for your property can be confusing. Keep reading to learn more about waterproof render and the other types of render available, the benefits of each, and which might be the best option for your home. What is Waterproof Render? Rendering Explained Render refers to a coating that is applied to the external walls of a building. It is a smooth and often white surface that you might see on the exterior of a home. Traditionally, render was a breathable and flexible covering that was made using a combination of water, lime, and an aggregate like sand. However, while this method hasn’t been as popular in the last decade, recently it has started to come back around and is still used for the conservation of period properties. Today, conventional render is made from a blend of sand, cement, and aggregate. That being said, many modern properties are free from cement. Newer render options can sometimes contain products that are designed to help with waterproofing and prevent algae growth on the walls. You can also find renders that are... --- - Published: 2022-06-14 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/what-is-cementitious-tanking/ - Categories: Condensation, Damp Will Cement Tanking a Cellar Keep Moisture Out? A basement or cellar space can be very susceptible to damp. This is because moisture can get in through the walls from the ground, and since the basement is below ground level, there is often much more moisture around the external walls from the soil, especially in wet weather. This is why if you have a cellar in your home that has not been damp-proofed, you might notice that things inside the cellar are affected by damp and mould after a while, or the walls in the basement are moist even if you do not have any damp problems in the rest of your home. If you want to be able to use your cellar for more storage or are considering converting it into a liveable area of your home, then cement tanking your cellar can be an ideal way to keep moisture out and prevent any further damp problems. What is Cementitious Tanking and How Does It Work? If you are thinking about converting your basement so that you can use it for storage without worrying about damp affecting your belongings or you want to take advantage of the space to use it as a second living room, bedroom, or another room in your home, then protecting it from damp and flooding is one of the most important first steps to take.

It is necessary to get rid of the water, fix any underlying basement problems, and take steps to keep your basement dry if you are in the process of converting it into a liveable room. Keep reading to find out more about some of the common reasons why water leaks occur with basement conversions, what you should do if your basement is wet, and how to handle damp-proofing going forward with your basement conversion. What to Do If You Find a Leak in the Basement If you find a leak in the basement or go down into the basement and it is wet, here are some important steps to follow. 1 – Stay Safe It’s important to put your safety first if there is a water leak in the basement. Ideally, you should stay out of the basement until a professional arrives to advise you on what to do. Do not go into the basement with any electrical devices since this can lead to electrocution or shock. If you need to go into the basement, avoid touching any electrical devices or wet wires, and wear rubber boots to stay dry. 2 – Determine the Source The next step is to try and determine the source of the water.

If your home has had problems with damp in the cellar or basement, then you will already likely know how annoying it is to have a space in your home that you’re unable to use. Even worse, having damp in the home can also cause health issues for people living in the property. The good news is that damp does not have to put you off from utilising that unused space and adding extra rooms and value to the home. A cavity drain membrane system is the most ideal way to ensure damp proofing for a damp cellar, keeping your new room dry and safe for decades. Before converting your cellar into a liveable space, keep reading to find out more about this damp proofing system and why it might be an ideal choice for your property. Cavity Membrane and Damp Proofing Cavity membrane drainage systems are suited for using in cellars, basements, or vaults. The main purpose of such a system is for damp proofing, and a membrane made from high-density Polyethylene is typically used, which is installed on the floors, walls, and sometimes the ceilings of the basement. In many cases, it can also include a specific drainage channel that is installed to divert water towards a sump chamber.

With the rising price of property in the UK, more and more homeowners are considering converting their basements into a useable and liveable space rather than upgrading to a larger home. Utilising the space underneath a house has long been a popular option in other countries such as Canada and the US, and now there is a bigger move to convert basements in the UK as homeowners realise how much it can benefit them. Here are some of the main benefits of converting your basement in your London home. Ideal for City Living While there are different ways to add space to your home, any homeowner is aware that building into the back garden is often the only option if you want to build an extension on a house. This can often be a very restrictive option that might not always be possible if you are living in a city like London, where space is at a premium and outdoor spaces are often small. Some houses in London don’t even have a garden and you may be lucky to have a small back yard. Because of this, a basement conversion in London is the perfect option for anybody who doesn’t want to give up the small amount of precious outdoor space that they have.

Damp is caused by moisture that penetrates the walls and can lead to wet patches that over time can develop into more serious problems like mould, structural issues, and wet rot in the timber. Rising damp is one of the most serious types of damp to deal with in a property. It is usually a sign that there is some kind of problem with the damp proof course, a waterproof membrane that runs along the length and width of the internal walls to prevent moisture from getting into the walls and causing damp issues in the home. What is Rising Damp? Rising damp refers to a type of damp that occurs when water rises upwards in the walls from the ground beneath. This is usually a result of a failure or a breaching of the damp proof course since the main aim of the damp proof course is to prevent moisture from getting through. It is often more common in older properties that may have been built before adding a damp proof course was mandatory, especially if there is no damp proof course present. Older properties that have had the same damp proof course since when they were built may also be at a higher risk of rising damp since over time, the membrane can become less effective at repelling moisture and may deteriorate or become damaged with age.

Rising damp can be one of the most problematic types of damp in the home and is caused by moisture that rises up through the walls due to water collecting in the ground underneath or next to the walls. It can happen to almost any wall including walls that are constructed from bricks, blocks, or stone. It happens as a result of capillary action, where water is sucked up through tiny holes in the wall’s construction materials, which leads to water travelling upwards through the wall until it is pulled back down by gravity. Because of this, the moisture will usually only occur on the ground floor of a property and will usually stop at around 1. 2m high. However, you may notice some effects of rising damp higher up on the walls, including salt deposits, especially if your wall is covered in a non-breathable covering like vinyl wallpaper or washable paint. Signs You Need Rising Damp Specialists in Chelsea There are some common signs to look out for in your Chelsea home that could indicate a problem with rising damp.

In the UK, the average home will usually deal with a large amount of wet weather throughout the year, which ultimately increases the risk of damp problems. Due to the high amounts of rain that we get, you are probably not surprised to hear that damp is a common problem in many British properties as a result. If your home has a cellar or basement, the risk of damp is even higher since not only do homes with cellars tend to be older, but there is often also poor ventilation in this area of the home. Damp and other damp-related issues such as mould can appear anywhere in your cellar, but it’s most likely to show up on the internal walls. Damp in a cellar or basement can be the result of several different issues including condensation from the inside, moisture getting through from the outside, ineffective drainage, leaks, a bridged or broken damp proof course and more. Since the cellar or basement is often the coolest area of the property, this makes them particularly at risk of damp. When Might You Need Basement Damp Proofing? There are several situations in your home that might increase the risk of damp in the basement. Basement or cellar damp proofing might be needed in the cases of: Poor Grading Grading issues can often lead to rain or groundwater finding its way into the basement.

Whether you have a traditional log burning fire or your fireplace is decorative only, it’s never a good sign when you begin to see damp patches and staining appearing on the chimney breast in your home. While it might be tempting to simply paint over the damp or use it as an excuse to wallpaper a new feature wall in the room, the unfortunate truth is that damp in this area is unlikely to go away on its own and will probably come back in the future to ruin all your hard work. Figuring out the root cause and treating it as quickly as possible is important for dealing with damp issues on a chimney breast. What are the Common Causes of a Damp Patch on Chimney Breast? There are several common causes of a damp patch on your chimney breast, including condensation forming on the inside of the chimney, rain water or other sources of external moisture getting inside the chimney, or hygroscopic salts, which draw moisture into the walls. Reasons for the Damp on Chimney Breast: If you’ve noticed damp patches on your chimney breast, it could be due to one of the following reasons: 1. Rain Water: If rain water or other sources of moisture from outdoors are finding their way inside, this can lead to the signs of penetrating damp on the chimney breast.

However, problems that are caused by excess moisture in the home can lead to some serious structural problems. Older homes are often at a higher risk of developing damp issues since they were not typically built with the same damp-proofing measures as the newer homes are today. If you are looking at purchasing or already own an older property, it’s important to be prepared for the possibility of dealing with damp issues. Damp Proofing an Older Home – Common Causes of Damp: Many of the damp problems found in older UK homes are due to condensation and rain penetration. However, there are various problems that often lead to damp in older properties and understanding the potential cause of the problem is the first step towards successfully damp-proofing your home. Some of the most common reasons for damp are: Leaking Gutters: Penetrating damp occurs when water makes its way from the exterior and into the interior walls of the home. One of the biggest causes for this is problems with the gutters, which can often be seen in older homes. If your older home still has the same gutters that were installed decades ago, chances are that they are no longer effective for the amount of rainfall that we are getting today. Gutters are designed to direct rainwater away, rather than towards your... --- - Published: 2021-06-04 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/chemical-damp-proof-treatment/ - Categories: Independent Damp Surveying How Effective are Chemical Damp Proof Treatments? Damp is a common issue in UK homes due to the amount of wet weather that we get throughout the year. This is especially true if you live in an older home where the risk of damp is even higher due to the lack of damp-proofing treatments compared to newer homes in the country today. There are several different types of damp that can impact your home including penetrating damp, which involves moisture from the outside making its way to the inside walls of your home, rising damp, which occurs when the damp proof course is not working effectively and water reaches the foundations, and condensation damp, which is caused by a build-up of warm air inside the home that settles and condensates on the cold wall surfaces. If you want to treat or prevent rising damp inside your home, you may be considering the option of a chemical damp proof course. But how effective is chemical damp proofing, and is it a good solution for your home? What is the Damp Proof Course? A damp proof course is an important feature for any property. The purpose of the damp proof course is to provide a waterproof feature just about the outside ground level of your property. The aim of this is to prevent moisture from rising from the ground and into your property. It’s normally placed at around 150mm above the outside ground level, which is typically at the mortar joint above... --- - Published: 2021-05-08 - Modified: 2025-03-18 - URL: https://londondampspecialists.com/blog/independent-damp-specialist/ - Categories: Independent Damp Surveying Why Hiring a Damp Specialist is a Smart Investment If you live in the UK, you know that it’s not exactly the driest country in the world.

When caught early on, wet rot can be easier to repair than you might realise. However, if it is left unchecked for a longer period of time, wet rot can cause irreversible damage to the timber in your home and might require that the timber is completely replaced in order to ensure the property’s structural integrity. If you think that you may be dealing with wet rot in your house, it is important for the issue to be inspected and that repair work is carried out as soon as possible in order to ensure that the issue does not get any worse. Any property can suffer from wet rot regardless of whether it is an older property or a new build, and wet rot that is left to get worse over time can often lead to more serious problems such as mould or dry rot. https://www. youtube. com/watch? v=Z1k5U3rBrmo What is Wet Rot in Timber?

Timber rot is an issue that no homeowner will want to deal with, especially when it comes to dry rot. Dry rot is often the hardest issue to deal with when it comes to timber problems and decay since once a dry rot outbreak has begun eating away at the wood, it can be difficult to stop the spread. To make sure that the dry rot problem is completely removed from the home, it is often necessary to get expert knowledge and specialist treatment. In order to resolve a problem with dry rot, it is usually necessary to get a professional in to help you identify the causes of the dry rot and come up with the most appropriate treatments available and how to prevent future outbreaks of dry rot. Wood, which is the food source, along with moisture, both need to be present in a building in order for dry rot to occur. https://www. youtube. com/watch? v=ef7sdclJ-Yk What is Wet Rot and Dry Rot in Timber?

Rising damp is one of the most serious damp problems to occur in a home since it is often an indication of a problem with the damp proof course, which is a waterproof layer spanning the width and length of the internal walls to prevent water from getting inside and causing damp in your home. What is Rising Damp? Rising damp is a type of damp that occurs when water rises up the walls from the ground below. This is usually caused by an issue with the damp proof course. It can often occur in older homes where a damp proof course is not present, but might become a problem if your damp proof course is faulty or has not been correctly installed. Rising damp occurs due to capillary action, which is where water is sucked upwards through a small opening such as tiny holes in the bricks or stone of the walls. What Does Rising Damp Look Like? One tell-tale sign of rising damp is brown or yellowing patches on the ground floor walls, usually above the skirting boards. In some cases, the damp might also affect your skirting board woodwork and these might have signs of damp or rot.

Nobody likes to know that there are damp issues in their home, and rising damp can often be one of the most problematic. Rising damp is caused by moisture that is present in your walls as a result of water collecting in the ground underneath or next to the walls, where it will rise up through the structure of the wall. It can occur in almost any wall including walls that are made from bricks, stone, or blocks. Capillary action, where the water is sucked through a small opening through tiny holes in the bricks or stone, leads to the water travelling upwards through the wall. The water will usually stop rising at a height where the gravity will counteract this force and stop it. Rising damp will usually only occur on the ground floor of a property and tends to only reach a maximum height of 1. 2m.

Damp patches on the ceiling can be unsightly and worrisome. A damp patch on the ceiling on the ground floor of your home could indicate a leak in your plumbing system, while upstairs, it is more likely to indicate that there are problems with your roof. Problems with your gutters could also mean that water is being drained towards, rather than away from your home, which can also lead to damp patches occurring on both the ceilings and walls. Other possible reasons for why damp may occur in your home include excess condensation caused by poor ventilation in the rooms of your home, and old chimneys that do not have damp-proof solutions in place. The good news is that whatever is behind the damp patches that are appearing on your ceiling, there is a way to repair it. https://www. youtube. com/watch? v=ESZYuKSM8HM Is it Rising Damp or a Leaking Pipe?

Rising damp usually happens in old homes and occurs when the water from the ground rises into and through the capillaries of bricks and mortar of buildings. Over time, a musty smell will develop as more plaster is exposed to water. How high the water rises depends on the type of plaster used and the rate of evaporation. What you see on buildings walls when rising damp happens is due to the contents present in the ground water, such as soluble salts, chlorides, nitrates, and sulphates. When the ground water rises through the capillaries, the contents will follow along. However, the water would evaporate, leaving those salt contents behind. When rising damp occurs often, this allows more water to enter and then leave more of their salts behind, becoming even more concentrated over time. Furthermore, since chlorides and nitrates are hygroscopic, meaning that they can absorb moisture from the surrounding, a greater salt concentration will attract a greater amount of moisture. This can be worsened if the weather in your area is often humid. And blocking the dampness with decorations is not a solution as they can be contaminated by the salts too. Penetration damp Penetration dampness occurs when your external walls let in moisture. The moisture then penetrates into the inner walls. It can be responsible for cracking and peeling off of paint as well as the growth of mould and mildew. It is important to understand that... --- - Published: 2018-03-06 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/rot-problems/ - Categories: Condensation, Damp, Maintenance, Water Damage - Tags: Damp Repair, Dampness, Dry Rot, Dry Rot Bugs, Dry Rot Fungus, Dry Rot Health, Dry Rot Repair, Dry Rot Treatment, Dry Rot Woodwet rot Dry rot, wet rot, penetrating damp, rising damp, condensation: all water-damage problems faced by home owners and all problems that need to be fixed sooner rather than later. But each is a different issue with a variety of effects and treatment methods. One quick call to London Damp Specialists is all it takes to diagnose your damp or rot problem and here’s a quick guide to spot your rot. Dry Rot When damp is combined with poor ventilation you have the perfect feeding ground for fungus. The fungus is highly invasive and can affect any type or age of property. It feeds off timbers and quickly spreads into plaster through cracks and cavities. Common signs of dry rot are damaged timbers (often out of sight below floors or in lofts) and visible orange/brown dust before it manifests itself in fluffy white spores and mushrooming spores – the latter stages show an advanced case of dry rot. How is Dry Rot Treated? Dry rot needs to be treated professionally and quickly in order to halt any further spread and eradicate it fully. It can be a disruptive process as it involves plaster and timber removal and replacement as well as treatment with a dry rot-resistant solution. Wet Rot If there is a constant source of water ingress or a leak from somewhere in the property, wet rot will develop – it could be from leaky plumbing, damaged gutters, downpipes or deteriorated pointing. Whatever the cause, it needs to be sorted!

It is the smallest borough but the most densely populated, despite its accompanying price tag. Kensington’s exclusivity is perhaps rooted in its royal links – Henry VIII built a home where some of his wives lived and Queen Victoria was born and continued to reside here. Many of its buildings bear the signs of the Victorian building styles still favoured today: stuccoed fronts, impressive mansion blocks, and terraced rows filled with Victorian features such as high ceilings, beautiful fireplaces and well-proportioned rooms. Although the buildings themselves stand strong, they are susceptible to structural failings, age-related problems and general wear and tear. They deserve to be kept in as good a state of repair as possible to ensure they retain their value and longevity. Many issues faced by today’s property owners stem from the actual materials the Victorians and their predecessors used to construct many of Kensington’s buildings: London clay bricks, lime mortar, cast iron, leadwork and slate. Damp proof courses fail because they were constructed from slate and glass or were non-existent; many basements and cellars, which are now hugely popular, are highly susceptible to penetrating and rising damp because they were built without tanking or any similar protection from the surrounding damp earth; and building repairs carried out... --- - Published: 2018-03-02 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/damp-house-problems/ - Categories: Condensation, Damp, Water Damage - Tags: Condensation, Damp Repair, Dampness, Mildew, Mould How to identify a damp problem in the house Living in a damp house can be very dangerous and can cause you a lot serious health issues. As such, a little leak is something that should not be ignored. Although you might not be able to notice the immediate water damage, bacteria and mould growth can start within a short time of water intrusion. Damp homes have been found to be the cause of respiratory illnesses. A damp house is a conducive place for breeding of parasites and bacteria. It is, therefore, important to ensure that your property is well kept and regularly inspected to prevent you and your family members from getting sick. The following are different ways to help you know whether your home is damp: Condensation Condensation on the window is an indication of a damp house. Excessive condensation may be a sign of too much water vapour in the home. Condensation is an indication of a damp problem and poor ventilation. It is essential to ensure that you check your house regularly so to avoid exposing your family to diseases. Black mould Black moulds are another thing that you will notice in a damp house. Moulds are usually life threatening since the can cause severe diseases especially to those people with a lung condition. Make sure that you check the entire isolated ceiling, walls, door frame and window carefully to avoid causing more problems.

This problem is mitigated by modern building practices where properties are built with damp proof courses, in most cases impermeable plastic membranes to stop water passing through. But some buildings don’t have this precaution. The main causes of rising damp is simply down to groundwater. It’s basically moisture when the groundwater rises underneath or next to the walls of your home, and it doesn’t matter if the walls are made of brick, stone or block. The moisture rises through the small holes present in the mortar or brick. Eventually, gravity will stop the rise of the water, by counteracting the upwards force of the capillary action. On the whole rising damp will occur when the water has reached a height of 1. 2, but its effects – salt deposits, for instance, may be present at a much higher level because of the non-breathing wall coverings such as vinyl wallpaper or non-breathing paints. So, do you have rising damp? The signs are easy enough to work out. Do you have a musty odour or damp smells? Does your wall now have a low temperature very low in height? Are your floor timbers beginning to show signs of rot? Is the plaster in your walls beginning to crumble or blister? If so, it’s because of salt crystallisation.

This is the case in Old Fulham Houses. Here, the houses suffer from different types of damp, for example, the penetrating and rising damp. However, if you suspect that your house is having any type of damp, it is wise to contact a damp specialist who will analyse the situation and come up with the perfect remedy. In this article, we are going to provide you with information on both penetrating and rising damp especially if you are a resident at Old Fulham London Houses What is rising damp? Normally, rising damp moisture that starts eating the walls of the houses from the ground going up in a capillary action. To curb this problem, a contractor will have to identify carefully the type of dampness first. In many occasions, inexperienced surveyors might mistake this type of damp with condensation damp thereby recommend the wrong actions to take. In most cases especially in Old Fulham Houses, the cause to rising damp is a fault in either in the existing damp course or higher ground water level. Generally, rising damp does not exceed 1. 5 meters. What is penetrating damp? This type of damp occurs due to penetration from the roof, cracks in the walls or the wrong use of internal plaster. In Old Fulham Houses, most of the... --- - Published: 2018-02-28 - Modified: 2025-03-20 - URL: https://londondampspecialists.com/blog/water-damage-specialist/ - Categories: Damp, Condensation, Maintenance, Water Damage - Tags: Damp Repair, Mildew, Mould, Water Damage Repair Water, Water, Everywhere... Water damage to a property can be distressing and expensive. Whether the damage is a result of a leaking pipe, either from your house or from an adjoining property, or a leaky appliance, or there’s been a slow ingress of external water; the damage can be extensive. The first thing to do is isolate the cause. If it is from within your property, turn off the water at the mains to prevent any further water entering. If it is from a neighbour, let them know and advise them to turn off their water. Take photographs of any visible damage – you will need these in the event of an insurance claim. Remove any damaged or affected soft furnishings to prevent the spread of damp and mould – carpets, curtains, sofas, mattresses, whatever is in the immediate vicinity – and leave them to dry. Call your insurance company as soon as you can. Hopefully you will be covered but bear in mind they may not pay out if the damage is deemed to have been caused by a design flaw in any building work that’s been done. Your insurance company will probably either send out a surveyor to assess the damage, refer you to their preferred supplier of damp solutions or ask you to contact a damp expert yourself – someone like London Damp Specialist. We would survey the damage and send a report which would include readings from a damp meter and images of affected areas. Subject... --- ---
