Cost-Effective Solutions for Damp Issues: What You Need to Know

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. Look for damp patches on walls and ceilings, a sure sign that you need moisture control solutions.
  • Basement waterproofing – Below ground living space must be waterproofed and we offer affordable basement tanking in London; there are several ways to protect a basement, using water-resistant cement on walls and ceilings, or install a cavity drainage system, which comes in several forms, type A, B and C waterproofing. If you would like to know basement tanking cost, call London Damp Specialists on 020 7458 4864 and we will arrange for one of our surveyors to carry out an assessment.
  • Damp proof course (DPC) – Every building would have DPC membrane fitted between lower brick courses and this prevents rising damp from invading the building. In the event the DPC is damaged, damp can rise up the exterior walls and that leads to decay and damage. Check the entire perimeter of the house, looking for crumbling masonry and mortar.
  • Water resistant cement – Sika make excellent products that waterproof walls, floors and ceilings, which is primarily used in basement tanking; if you find a damp area of wall, you can remove all the damp plaster, let it dry out, then apply Sika cement that will seal the wall.

If you suspect that you have damp issues in your home, call London Damp Specialists on 020 7458 4864 or fill in the form on our website and we will send a surveyor to assess your property for damp and mould.

 Survey Add Ons

£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.

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.
