Prevent Seasonal Damp in Your Home With These Year-Round Tips
We all joke about the British weather and the endless drizzle and wet climate actually pose a serious risk for property owners in the UK. Rising and penetrating damp, condensation, woodworm and dry rot are all a very real threat, and with that in mind, here are a few tips to prevent seasonal damp damaging your home.
- Winter dampness – As you would expect, damp is more likely to be an issue in the winter months, due to the cold and musky weather. You should use your central heating to heat the whole house, as this dries out the moisture in the air; you might be reluctant to heat rooms that are not in use, yet a few hours 2-3 times a week will help prevent the onset of damp.
- Generate a good airflow – Damp and mould thrive in a still and humid environment, which is why good ventilation is so important. You can use natural ventilation by opening a few windows, or the use of extractor fans installed in the right locations. This is equally important all times of the year, especially in the summer when temperatures rise.
- Commission a damp survey in spring – We at London Damp Specialists are extremely busy after the winter as London homeowners book a damp and mould survey for an accurate assessment of damp and mould in their home. Our homebuyer damp survey is ideal; it comes in 3 levels, depending on the extent of the survey, plus there is an additional service where we analyse plaster samples for moisture content.
- Summer roof inspection – The roof is a critical component that keeps the harsh weather at bay and a leaking roof is sure to cause damp damage. It is important to clean out guttering, as this provides an escape route for excess rainwater; a bout of heavy rain can lead to water running down the exterior walls and this causes penetrating damp. Inspect all parts of the roof, looking for missing or broken shingles and should you find missing tiles, they should be replaced immediately.
- Add extra insulation prior to winter – You could add fibreglass material in the loft to help retain the heat in the home; if your home was built with cavity walls, you can have insulating foam pumped into the cavities and that will keep the home warmer for longer periods. Cavity wall insulation can also save energy as your central heating does not have to work as hard.
- Deep clean the bathroom – This will remove mould and mildew, which can be hazardous to your health; use powerful cleaning products and make sure you clean every inch of the bathroom and this will prevent mould and mildew growth.
At London Damp Specialists, we offer a wide range of damp proofing solutions and if you would like to have your property surveyed for damp and mould, call us on 020 7548 4864 or fill in the form on this website.
We offer an unconditional 30-year guarantee on all damp proofing work, which gives London homeowners peace of mind.

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.
