Homebuyers Damp Report
If you’re buying a new home or property in the London area, you may need a professional damp survey. A thorough damp survey from a professional will look for all and any types of damp in the property and could help save you thousands of pounds. London Damp Specialists is on hand to carry out your damp and timber report.

Many properties on the market for sale have had quick fix and cheap damp repairs just to sell. It’s not until a few months after you move in that the damp and condensation issues start to creep back. They might start showing themselves with horrible mould and damp patches reappearing. Occasionally, the extent and severity of the dampness in a property will force you to vacate while renovations are done and the inside is revamped – extra cost and upheaval on top of moving.
But call London Damp Specialists before you exchange contracts and we will carry out a damp report that can find hidden and underlying issues that may not be visible to the naked eye. We use the most advanced technology available to give you peace of mind that your new home is free of damp.
Nearly every old property has some sort of damp, and if there is damp, we will find it.
What Should You Do if Damp is Discovered?
The first thing to do if we uncover damp during our survey is – don’t panic! The very word ‘damp’ can strike fear into a homeowner or buyer but it isn’t necessarily always doom and gloom. We will be happy to discuss our survey’s findings with you so you know the full extent of the issue, the levels of repair needed, the costs and the potential disruption to you and your family.
Armed with this information, you can then make a call on whether to go ahead with the house purchase. If you have your heart set on the property, the cost of repairs may well be outweighed by the time you’ll spend living there. We’re always happy to discuss damp issues with you.

Case Studies
Long periods of dull and wet weather create the perfect conditions for damp and mould to thrive and we haven’t seen the Sun for months. Heavy rainfall is sure to cause damp issues to older properties.
We are proud to issue a comprehensive 30-year guarantee. If any area that we have repaired requires further work, we are happy to carry out the work at no cost to the customer. This is a reflection of our high standard of workmanship and we have a great reputation within the industry.
The cost depends on the level of survey you choose; check our homebuyer survey page for details and prices. We also offer an add-on service, lab analysis of plaster samples taken from various locations. The cost of the survey is deducted from the cost of the remedial work.
Yes, our surveyors do take photos in order to show the customer specific areas.
Our surveyors have an array of tools, equipment and devices; thermal imaging cameras, moisture meters (both varieties), borescope cameras and they also use drone imagery. A surveyor would even have spares, while our damp proofing teams have fully equipped mobile workshops.
Damp surveys and remedial work can be carried out year-round and winter is likely to be less convenient for the occupants. Sometimes it is necessary to zone off the property until the work is completed.

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.
