About London Damp Specialists

We have been inspecting London homes since 1981, a family-run business that services all London Boroughs and our surveyors are fully certified with many years of hands-on experience inspecting London properties. We have a close working relationship with one of London’s top damp-proofing companies and Qualified to industry standards (CSRT & CSSW).

If you are a property owner in London, you should be aware that damp is a very real threat. We have a wet climate here in the UK and because London sits on the Thames Valley Basin, the ground is largely clay-based, which holds moisture. Damp can come from the ground, or water can enter the building through the roof or even the external walls. A damp atmosphere is an environment where mould can flourish and that can be a serious health hazard. We provide independent damp surveys for London property owners, which is the only way to be sure that your home is free from damp, mould and timber rot.

Basement Waterproofing

Many London homes have underground living space, which is the best alternative when you can’t build up or add an extension to the building. Many terraced homes in our capital have a basement, which can be used for storage or living space and damp is a serious threat due to the high level of moisture retention in many parts of London. When we survey a London property for damp, we give the basement a thorough examination, looking for the tell-tale signs of damp, mould and timber rot. The client receives a detailed report in their inbox the day after the survey and we can recommend the best basement waterproofing in London from an established company.

Condensation

Condensation is a common occurrence, especially in the damp autumn and winter months, when cold meets warm and droplets of water form on the inner window surfaces. Running hot water, drying damp clothing indoors and cooking are all causes of condensation and if mopped up promptly, condensation can be managed. Penetrating damp can lead to a build-up of water droplets on internal walls and window frames. A damp and humid atmosphere is a breeding ground for mould; black, green, brown and creamy white fungi present a health hazard. Our surveyors and condensation specialists and they can recommend the best solution.

Rising damp
Rising Damp

Ground moisture can seriously damage a building, as it spreads through capillary action, climbing brickwork, mortar and render. Eventually, it will penetrate the interior walls, causing plaster to crumble and if not addressed, damp will spread throughout the building. Every building has a damp proof course, which is typically inserted between the first couple of brickwork courses and this acts as a moisture barrier, preventing damp from crossing the barrier. If the DPC is compromised in any way, damp can move through the building materials, causing damage as it rises up the walls.

Timber Treatment
Timber Treatment

Houses typically contain a lot of timber; wooden joists and rafters in the roof, wooden door and window frames, floors, skirting and architrave. Up to 75% of the average family home comprises of timber; there are treatments to preserve wood and prevent fungi and woodworm. Signs of timber rot include a musky smell in the house, crumbling and brittle wood, while woodworm leaves tiny holes with small mounds of dust nearby, in which they bury their eggs. We work closely with woodworm treatment specialists and they cover all areas of London.

Penetrating & Rising Damp
Penetrating Damp

Moisture that enters via the roof or external walls is known as penetrating damp, which is an issue for many homeowners. A leaking roof can be devastating if rainwater enters the internal roof structure, which is why you should arrange for an independent damp survey from London Damp Specialists. If damp penetrates the external walls, paint and wallpaper bubbles and peals, while a humid environment allows mould to thrive and that can be a health hazard. Wet and dry rot, along with woodworm, can infect a damp and humid house and this can lead to considerable damage to plaster and timber. If penetrating damp treatment is recommended, we can put you in touch with a top-rated provider that issues a full 30-year warranty on all damp-proofing work.
