Leak to dry to treated, one company in Leatherhead
Leatherhead's housing runs from solid-walled Victorian and Edwardian terraces around the town centre to 1930s semis on the Fetcham and Ashtead fringes, with older cottages near Mickleham and newer builds around Randalls Park. Solid brick, retrofitted glazing and the town's low-lying position near the River Mole all combine to trap moisture and encourage mould.

Common causes of mould in Leatherhead homes
Solid-wall Victorian and Edwardian terraces
Many terraces near Leatherhead town centre were built without cavity walls, so moisture migrates through solid brickwork whenever pointing or render fails. This shows up as black mould on chimney breasts, in alcoves and along external walls, particularly in bedrooms and behind furniture pushed too close to cold masonry, and it keeps returning until the brickwork itself is repaired.
1930s semis with retrofitted double glazing
The semi-detached streets around Fetcham and Ashtead were built with airbricks and open chimneys that later double glazing and cavity insulation sealed up, cutting ventilation while moisture output stayed the same. Condensation now collects on cold bedroom walls, in bathrooms and around window reveals, feeding black mould that spreads behind wardrobes and headboards if airflow is not restored.
Low-lying properties near the River Mole
Homes around Randalls Park, Thorncroft and other low ground near the River Mole sit on a high water table and have a history of surface water and flooding. Past inundation or slow-draining ground pushes penetrating and rising damp into ground-floor walls, leaving persistent black mould that resurfaces after decorating unless the underlying moisture source is properly traced and fixed.
What our customers say
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.
