Damp Proofing Specialists in London: Extensive Expertise and Coverage
We are all aware of the wet climate we have to endure here in the UK, we seem to go for weeks without any sunshine at all! The wet conditions mean that dampness thrives and that can cause serious damage to property. Moisture rises from the ground and penetrating damp attacks the structure from the ground level up and if not addressed, rising damp can cause thousands of pounds of damage.
At London Damp Specialists, we are proud of our damp proofing services and we cover London and the Home Counties, offering a range of specialist services to combat and prevent dampness from damaging homes and offices.
As a property owner, you should investigate any signs of damp or moisture damage as this can save you a lot of money. We are happy to quote for a range of damp proofing services.
Homebuyer survey
If you are thinking of buying or selling a property in the London area, our homebuyer survey is something to consider. For the seller, you can show any potential buyer that you have carried out a full damp survey with a detailed report issued within 24 hours of survey completion, and if you are buying, you need to be sure that the property is free from rising damp and wood rot.
What happens if we find damp issues in the property?
In the event our survey reveals damp issues, we present you with a written quotation for the remedial work and we work with you to ensure that the work is carried out as soon as possible. The longer you leave it, the more damage is caused, so we do what we can to provide timely repairs and preventions.
Three levels of survey
Our homebuyer survey has 3 levels, which are as follows:
- Level 1 survey – The level 1 survey involves a thorough inspection of all exterior and interior walls and floors, specifically looking for signs of dampness and moisture damage.
- Level 2 survey – This survey includes all of the level 1 survey, plus we closely inspect all timber in the property, including roof joists and loft timbers, looking for signs of rot and moisture damage.
- Level 3 survey – The level 3 survey incorporates levels 1 & 2, plus we test with thermal imaging, we test the air for humidity, we use borescope cameras, drome imagery and ventilation flow testing.
There is an additional service that tests for moisture in plaster; we take up to 10 plaster samples throughout the building, looking for signs of moisture.
Penetrating damp is a serious threat to properties in the UK and if you are looking to sell your home, it is good if you can show potential buyers the survey report that shows there are no damp issues. If, on the other hand, you are planning to acquire a property, the homebuyer damp survey ensures that there are no issues and you can move ahead with confidence.
Call us on 020 8528 3864 anytime and schedule a damp survey to find out if your property has damp issues.

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.
