Preventive Measures Against Rising Damp

As the days grow colder, the annual damp season sets in and your home may fall prey to the dangers of excess moisture that can harm both the structure and your health! You can usually tell that you have a damp problem from signs like excess condensation, discoloured or damaged walls, and an unpleasant musty odour that permeates the house. If you see this happening, arrange for a damp and timber independent survey right away!

Ideally, your home will never show signs of damp because precautions are already in place! The following are some of the preventative measures that you can take to keep your home warm and dry all year long!

Repair or Replace The Damp-Proof Course – The main cause of rising damp is a faulty damp-proof course. Older properties might lack one entirely! Most damp-proof course issues can be treated by a damp specialist who injects a special damp-proofing cream directly into your wall through holes drilled in the wall to form a new course. Once the injected cream has cured, it provides a strong protective layer that stops moisture from rising up through the walls. In some severe cases, you may need to have an all-new damp-proof course inserted, but this is an invasive procedure that involves removing portions of the wall, you will definitely want to consult with an independent specialist damp surveyor before attempting this!

Lower The Exterior Ground Level – In some cases, the damp-proof course isn’t the issue. It could be the structure’s exterior ground level exceeds the height of the damp-proof course, which allows moisture to seep down. If the higher ground level is the result of natural build-up over time, you may be able to dig out the excess soil, so the surface drops below the damp-proof course’s level. If decking or stonework has been constructed adjacent to or connected with the house above the damp-proof course, it has to be dropped down below it.

Add A Coat Of Damp-Proof Paint – An older property will be more susceptible to damp issues because of its materials ageing and growing more porous, which over time will allow moisture to come in. A coat of silicone-based and water repellent, damp-proof paint can help a lot! Seeking an independent damp and timber surveyor’s advice would be best to ascertain if this simple method will be effective for your home.

Use A Dehumidifier And Ventilate Your Home – Excess condensation in your home can be quickly reduced by a dehumidifier. Dehumidifiers suck moisture out of the air to reduce the humidity level, preventing condensation on windows and walls during the cold season. The most cost-effective way to prevent condensation is to keep your property well ventilated by opening the doors and windows during the winter when the weather permits.

£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.
