Damp, mould & leak services in Westerham
Westerham's housing stock spans 17th-century timber-framed cottages, Victorian terraces along the High Street, and interwar semi-detached properties on the town's fringes. Many homes retain original solid brick walls, clay peg-tiled roofs, and single-glazed windows, all of which make properties in this North Downs market town particularly susceptible to penetrating damp, condensation, and moisture ingress.

Common damp problems in Westerham homes
Penetrating Damp in Period Stone and Brick Cottages
Westerham's older cottages, particularly those clustered around the Green and along Hosey Hill, were built with solid stone or early brick construction that lacks any cavity or modern damp-proof course. Prolonged rainfall driven by prevailing south-westerly winds across the North Downs saturates these walls, allowing moisture to penetrate inwards and produce damp patches, tide marks, and deteriorating internal plaster.
Roof and Chimney Leaks on Victorian and Edwardian Terraces
The Victorian and Edwardian terraced properties along Westerham's High Street and surrounding streets commonly feature ageing clay peg tile or plain tile roofs with original lead flashings around shared chimneybreasts. Over time, mortar pointing on chimney stacks erodes and lead flashings lift, allowing rainwater to track down into bedroom ceilings and upper-floor walls, often going undetected until significant internal damage has occurred.
Condensation and Black Mould in Interwar Semi-Detached Homes
Interwar semi-detached properties on the edges of Westerham, including those near Force Green and Squerryes, were built with narrow uninsulated cavity walls and minimal ventilation provision. Modern occupant lifestyles generate considerably more moisture than these homes were designed to handle, leading to persistent condensation on cold external walls and window reveals, and subsequent black mould growth in bathrooms, kitchens, and corner bedrooms.

Service was excellent! Explained the whole process thoroughly, arrived on time when carrying out the survey. The survey was detailed and exactly what I needed for my insurance. They returned to carry out the treatment the following week. 10/10 would highly recommend.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
