Damp, mould & leak services in Leatherhead
Leatherhead's housing stock spans Victorian and Edwardian terraces in the town centre, inter-war semis across Fetcham and Bookham, and large detached properties in Oxshott and Tyrrells Wood. Older solid-wall construction, clay-heavy Surrey soils, and the River Mole floodplain combine to create persistent damp, mould, and water ingress challenges across multiple property types.

Common damp problems in Leatherhead homes
Rising and penetrating damp in Victorian town centre terraces
The older terraced streets near Leatherhead town centre contain many properties built before the introduction of damp-proof courses. Solid brick walls absorb groundwater readily, particularly given the area's clay subsoil, which retains moisture after wet periods. Owners frequently report tide marks on lower walls, crumbling plaster, and salt efflorescence that worsen through autumn and winter.
Condensation mould in post-war semis across Fetcham and Bookham
The large concentration of 1940s and 1950s cavity-wall semis in Fetcham and Bookham were built with minimal insulation and basic ventilation. Modern draught-proofing and double glazing fitted by successive owners trap moisture-laden air inside, leading to black mould growth on cold external corners, behind wardrobes, and around single-glazed utility areas that were never upgraded.
Hidden roof and chimney leaks in Tyrrells Wood and Oxshott detached properties
Larger detached homes in Tyrrells Wood and Oxshott frequently feature complex rooflines with multiple valleys, original clay plain-tile coverings, and redundant or still-active chimney stacks. Mortar failure and cracked flaunching allow water to track silently into roof voids and down chimney breasts for months before staining appears on ceilings or internal walls, by which point structural timbers may already be affected.

Jensen B, via Google
I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.
