Damp, mould & leak services in Keston
Keston's housing stock is predominantly mid-twentieth century detached and semi-detached properties, alongside older Victorian and Edwardian homes near the village centre. The rural-fringe setting, elevated ground, and proximity to Keston Ponds and surrounding woodland means properties face above-average exposure to moisture, driving persistent damp and mould concerns across a range of property types.

Common damp problems in Keston homes
Penetrating Damp in Older Village Properties
The older brick-built properties clustered around Keston Village centre were constructed using solid wall techniques without modern cavity insulation or effective damp-proof courses. Prolonged exposure to wind-driven rain on their exposed elevations allows moisture to penetrate directly through the masonry, causing damp patches on internal walls, peeling plaster, and mould growth, particularly on north and west-facing elevations.
Condensation and Mould in Post-War Semis
Keston Mark and surrounding roads contain a high proportion of 1950s and 1960s semi-detached homes with limited ventilation in kitchens and bathrooms. These properties were not designed for modern living patterns, and inadequate air circulation traps moisture indoors, leading to condensation mould on window reveals, ceiling corners, and behind fitted wardrobes placed against external walls.
Hidden Leaks in Leafy Rural-Edge Dwellings
Properties backing onto woodland around Leaves Green and near Keston Ponds frequently suffer from blocked gutters and downpipes caused by falling leaf debris. When gutters overflow undetected, water tracks down behind render and fascia boards, saturating roof structures and upper-floor wall cavities. These hidden leaks often go unnoticed for months, causing significant timber decay and internal staining before being identified.
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.
