Home Insurance and Damp: Critical Information for Homeowners
We all have home insurance, or at least we should in order to have peace of mind, yet many UK homeowners have not read the small print and therefore, they are not quite sure what their home insurance actually covers.
In this short article, we offer important information regarding home insurance and whether it covers damage caused by damp.
Damage caused by damp
Most home insurance policies actually cover damage that is caused by damp and moisture; if, for example, damp causes wallpaper or paint to peel off the wall, the insurance should cover replacing the wallpaper or paint, yet the policy would not cover damp repairs, which must be carried out before you can repaper the walls. In the event the DPC membrane is compromised, this will allow rising damp to climb the walls, and the cost of repairing the damp proof course would probably not be covered.
Different types of damp
There are numerous forms of damp, which are as follows:
- Rising damp – This is caused by a damaged damp proof course at ground level and damp can then rise up the external walls.
- Penetrating damp – Penetrating damp can affect any part of a building, from the roof to the foundations. Crumbling masonry and inferior mortar are common causes of penetrating damp, while blocked guttering and a leaking roof can also lead to penetrating damp.
- Condensation – Condensation forms when moisture forms on surfaces that have different temperatures. If the temperature outside is much colder than inside, condensation typically forms on the inside of the window panes, which runs down onto the window mantle and the timber frames, which can be the onset of mould, mildew and wet rot.
- Mould & mildew – Mould and mildew are caused by the presence of damp; if you should notice a musky smell in the house, this is a sure sign that you have mould somewhere. Regular inspections are the best solution for monitoring damp, mould and mildew; you can contact us at London Damp Specialists and arrange for one of our qualified damp surveyors to inspect the property.
Woodworm, wet and dry rot
Most home insurance policies do not cover woodworm, dry and wet rot; you should always read the small print on any insurance policies, which will give you a clearer understanding of what is covered and what is not.
Damp surveys
If you are about to make an offer on a London property, you should commission our homebuyer damp survey that will give you a detailed report on the status of your property regarding damp issues. We also present a written quote for any remedial work that we recommend; all our work is guaranteed for 30 years, which is a reflection of our high standard of workmanship.
To summarise, most home insurance policies will not cover damp proofing of any kind, they do, however, cover damage that is caused by damp.

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.
