Damp, Mould & Timber Treatments – Top Services Offered by a London Damp Proof Specialist
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 like to work to the customer’s schedule.
Damp proofing services
Services include;
- Rising damp treatment – Dealing with moisture from the ground; every building should have a damp proof course, a waterproof membrane installed between the first brickwork courses. Damaged DPC would lead to rising damp if the ground is wet and we can identify and repair/replace DPC membrane or apply DPC injection.
- Basement waterproofing – Every below-ground room needs to be protected from moisture penetration. Cavity drainage systems are often used for basement protection; basement tanking, the application of water-resistant cement and screed. When there are options, we explain the pros and cons of each and will always have your best interests at heart.
- Penetrating damp – Damp that attacks the roof or exterior walls demands a thorough assessment to find the underlying cause and recommend a solution. A leaking roof would likely lead to damp impacting joists and rafters, which might be noticeable by a musky smell, a strong indication of timber decay.
- Timber treatment – Wood preservation can protect your home for 20 years; we apply effective chemical solutions to protect from woodworm, wet and dry rot. If damp has been present a while and timbers are damaged, they may need to be replaced.
At London Damp Specialists, we are proud of our excellent reputation within the industry, which is reflected by a 30-year warranty that we issue on all our work. Give us a call on 020 7458 4864 during office hours or fill in the online form on this website.

Survey Add Ons
Add On 1
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.
Add On 2
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 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 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
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 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
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
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
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
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.
