How To Prevent Seasonal Damp In Your Home

Here come the rains again as London braces for another wet winter when we can look forward to the cold damp constantly encroaching on our homes. The winter months can be miserable as everything feels damp thanks to the warm air indoors condensing when it comes in contact with the cold windows and walls. If things get too damp, it can wreak havoc with your home’s structure as well as your health, which is why it’s a good idea to order an independent damp and timber survey of your home to make sure it stays dry all year long!

If the damp has already established itself in your home, you may notice an unpleasant, pungent mould stench. This is because the excess condensation creates a damp environment that encourages the growth of toxic moulds and mildew that put you and your family’s health at risk! Instead of just waiting for spring, here are some things you can do now to fight off the winter damp!

Windows – Stagnant indoor air traps moisture, so open your windows to allow fresh air to flow through when the weather permits, which also lets moist, humid air escape. Condensation builds up quickly on windows, tiny moisture droplets form as the chill outdoor air hits the glass facing the warm interior. This damp can be prevented by drying off windows and sills with a clean towel every morning.

Ventilation – It’s always best to prepare for winter by making sure your home is properly ventilated before the cold weather arrives. Having your home inspected by an independent damp surveyor in the fall is a great way to stave off the seasonal damp before it can set in. Your home should have proper ventilation installed, such as the exhaust fans in bathrooms and kitchens that help decrease humidity while you are taking a shower or cooking. If you run your kitchen exhaust fan while the kettle’s on the boil, you can reduce the humidity by 50%! Making sure your home is well-ventilated will help keep you dry all winter.

Insulation – Condensation is attracted to cold surfaces, so having a well-insulated home will keep the temperature higher to reduce dampness. Insulation keeps the warm air inside and the cold out so your home won’t get damp. Poorly installed insulation actually traps moisture in, which is why you should have an independent damp surveyor check for insulation problems that can encourage the growth of wet rot and mould, which are dangerous for your home and your health! Proper insulation is truly a great defence against the seasonal damp.

At London Damp Specialists our experienced surveyors use state-of-the-art technology to diagnose damp issues, so our inspections are always performed to the highest standard. If you have a rising damp problem, just call London Damp Specialists on 020 7523 5882 and we will dispatch an independent damp surveyor near you to help ascertain your damp problem.

£299 + VAT
Lab Analysis Of Plaster

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.

£299 + VAT
Mould Lab Swab Testing, qPCR on DNA

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.

Add to Survey

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

Damp Meter

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

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.

Drone Inspection

Drone Inspection

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

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

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

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 Lab Swab Testing

Mould Lab Swab Testing

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.

Lab Analysis of Plaster

Lab Analysis of Plaster

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.
