The Effects of Climate Change on Damp in London Homes

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. If your gutters become blocked, this will send rainwater cascading down the exterior walls. If you have overhanging branches above your roof, wet leaves and small twigs can easily cause a blockage and that is definitely something to avoid. Guttering is not for show, it performs a critical task, to channel excess rainwater away and down to the ground drains and any blockage will cause damp to infect the exterior walls.

Rising Number of Damp Surveys

In London and the Home Counties, the number of damp surveys is on the rise, which is largely due to climate change. We are extremely busy checking London homes for damp issues and that doesn’t look like it will change anytime soon, while a wide range of damp proofing services are on offer to London property owners.

Attention Homebuyers

If you are planning to purchase property in London, you should commission our homebuyer survey, which is designed to assess a building for damp and mould. We provide a quote for recommended damp repairs and all our work is guaranteed for a full 30 years.

Concealing Evidence

Many London property owners conceal evidence of damp damage, which can be done with a few coats of paint, so if you are a potential buyer, make sure you have the property surveyed for damp, to be 100% sure that the building is, in fact, damp-free.

Call London Damp Specialists on 020 8528 3864 and book a damp survey and let the professionals inspect your home for signs of damp, mould and mildew.

 Survey Add Ons

Add On 1

£299 + VAT
Lab Analysis Of Plaster

Laboratory analysis Of plaster identifies hygroscopic salts such as chlorides and nitrates. which indicate whether damp is caused by rising groundwater or by plumbing leaks, This testing removes guesswork, allowing the exact source of moisture to be identified so the correct treatment is applied rather than carrying out unnecessary damp-proofing work.

£299 + VAT
Mould Lab Swab Testing, qPCR on DNA

qPCR DNA mould testing detects microscopic mould spores that are invisible during a normal inspection and van remain hidden behind walls, floors. or inside building rkaterials. It identifies the exact mould species present and the contamination level, allowing hidden mould problems to be confirrned and properly treated before they affect the property or occupants’ health.

Add to Survey

Qualifications: All our surveyors are PCA and CSRT qualified for remedial treatments and also CSSW qualified for structural waterproofing.
Next day report: You will receive the report within 24 hours of the inspection taking place.

The survey fee will be deducted from the cost of any recommended repairs.

These are the tools we use

A damp meter

A damp meter

A damp meter is a diagnostic tool used to detect and measure moisture levels within building materials such as plaster, brick, timber, and concrete.

Borescope camera

Borescope camera

borescope camera is a small inspection camera attached to a flexible semi-rigid cable that allows you to see inside areas that are otherwise inaccessible.

Inspection Drone

Inspection Drone

A drone is a remotely operated aerial device equipped with a camera that allows visual inspection from above without the need for scaffolding or ladder.

Air Humidity Sensor

Air Humidity Sensor

Air humidity sensor measures the amount of moisture present in the air, expressed as relative humidity (RH) in percentage. It helps determine whether indoor conditions are contributing to condensation, mould growth, or damp-related issues.

Thermal Imaging Camera

Thermal Imaging Camera

A thermal imaging camera detects temperature differences on surfaces by using infrared technology to produce a heat map image. In damp investigations, it helps identify cold spots, moisture intrusion, insulation defects, thermal bridging and leaks.

Air Flow Ventilation Detector

Air Flow Ventilation Detector

An air flow ventilation detector measures the movement and volume of air passing through vents, extractor fans, and air bricks. It confirms whether ventilation systems are working properly and achieving adequate air changes within a room. Poor airflow leads to trapped moisture, high humidity, condensation on cold surfaces, and ultimately mould growth.

Mould Swab Test Kit

Mould Swab Test Kit

A mould swab test is carried out to confirm the presence of hidden mould growth and identify the specific species involved. Surface mould is not always visible, especially behind furniture, inside cavities, or within ventilation systems. Laboratory analysis of a swab sample determines whether active mould spores are present and what type they are, which helps assess potential health risks and decide the correct remediation approach rather than relying on visual assumption alone.

Plaster Salt Analysis Lab

Plaster Salt Analysis Lab

Laboratory analysis of plaster is used to identify the type of salts present within the material, typically chlorides and nitrates. The presence and concentration of these salts help determine whether the moisture source is consistent with rising damp, ground contamination, or another forms [sic] of water ingress. such as mains water leak, This removes guesswork and prevents misdiagnosis, ensuring the correct remedial treatment is specified rather than applying unnecessary or ineffective solutions.
