When to Call a Damp Specialist: Warning Signs to Watch For
Owning property here in the UK comes at a price and in such a wet climate, damp is a real issue. Rising damp can creep up a building, starting at ground level, damaging timber, brickwork and plaster in the process. Damp can cause thousands of pounds worth of damage to a building and in this short blog, we highlight a few tell-tale signs that it is time to call in London Damp Specialists.
- Damp patches on the interior walls – Check all rooms looking for damp patches on walls and ceilings, which is a clear sign that you need to contact a specialist. The professional will identify the cause of the issue and recommend treatment.
- Mould & mildew growth on window sills – Humid conditions are perfect for mould and mildew growth, while condensation thrives in moist conditions. Bathrooms and kitchens are prime locations for heavy condensation, which is why you should create some ventilation in these spaces.
- Water seeping down exterior walls – Blocked guttering causes excess rainwater to run down exterior walls, which is something to avoid at all costs. Most UK homeowners get a local roofing contractor to carry out a roof inspection, which should be an annual event; the tradesman checks roof tiles, clean out guttering and looks for signs of leaks.
- Musky odour – Damp is always accompanied by a strange musky odour, so if you notice this, it is time to call in London Damp Specialists on 020 8528 3864 or simply fill in the form on our website. Lack of ventilation only makes the situation worse, especially in the winter months.
- Insect infestations – Insects love damp and humid conditions and if you notice ants, mites or crustaceans, this is a sure sign that damp is present. You could call in a pest control company, but we recommend sorting out the dampness, as this will drive the insects out, as the environment will not be suitable.
- Paint discolouration – Damp and mould cause paint to discolour and eventually rot will set in; now is the time to have your property surveyed for damp and mould, we are a family-owned business that is well established in London and the Home Counties and we can match any legitimate quote for damp survey and work. The earlier you catch penetrating damp, the easier the fix and we offer a no-quibble 30-year guarantee on all our work, which is carried out by experienced and qualified tradesmen.
Do a regular inspection, looking for all of the above and if you don’t find anything, a big congrats from us. Be proactive regarding damp and mould, as we live in a wet climate, with a rainy season all year round, wet ground is the ideal place for a structure to be under attack.
If you are looking to buy property in the London area, give us a call on 020 8528 3864 or complete the online form and we can arrange to carry out a homebuyer survey and provide you with a detailed report within 24 hours.

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.
