Leak to dry to treated, one company in Forest Row
Forest Row's housing runs from timber-framed Wealden cottages and sandstone-built villas around The Square to 1930s semis and later estate homes off Hartfield Road and towards Ashurst Wood. Solid walls, small windows and proximity to Ashdown Forest's damp, wooded ground mean many properties struggle to dry out, leaving mould a recurring problem on walls, ceilings and behind furniture.

Common causes of mould in Forest Row homes
Sandstone cottages with penetrating damp
Older cottages near The Square and along Hartfield Road are often built from local sandstone or brick with solid, non-cavity walls. These absorb moisture readily during Sussex's wetter months, especially where pointing has worn or render has cracked. Once water gets in, it tracks through to internal plaster, producing damp patches and black mould on chimney breasts, external walls and ceilings that will keep returning until the entry point is properly sealed.
1960s and 1970s homes with poor ventilation
The estate housing built around Ashurst Wood and off Lower Road in the 1960s and 70s typically has smaller rooms, thinner walls and original extractor fans that no longer clear moisture effectively. Cooking, bathing and drying laundry indoors push humidity up quickly, and without adequate airflow it condenses on cold surfaces overnight. This shows up as black speckling around bathroom tiles, bedroom windows and wardrobe backs, particularly in north-facing rooms that rarely see direct sun.
Woodland-edge properties and a high water table
Homes close to Ashdown Forest and Weir Wood Reservoir sit on ground that stays damp for long periods, with clay subsoil slowing drainage after heavy rain. This raises groundwater pressure against foundations and can drive rising damp into ground-floor rooms, especially where original damp-proof courses have failed. Furniture placed against external walls traps residual moisture, creating hidden mould growth that often goes unnoticed until a musty smell or staining gives it away.
What our customers say
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.
