Leak to dry to treated, one company in Perivale
Perivale's housing stock is largely 1930s semi-detached and terraced homes built along the Western Avenue corridor, many with solid brick or early cavity walls, alongside post-war council housing near Horsenden Hill and low-rise flats close to Perivale station. Older single-glazed windows, solid walls and proximity to the A40 and Grand Union Canal all raise condensation and damp risk, encouraging mould in bathrooms, bedrooms and behind furniture.

Common causes of mould in Perivale homes
Solid-wall semis and penetrating damp
Many of Perivale's 1930s semis have solid or early cavity brick walls with render that has aged and cracked over decades. Rain-driven moisture works through these elevations, particularly on walls facing prevailing weather, and tracks inwards to chimney breasts, external walls and bedroom corners. Left untreated, this penetrating damp feeds persistent black mould that keeps returning after redecoration until the entry point outside is actually repaired.
Post-war flats with poor ventilation
Council-built flats and maisonettes near Horsenden Hill and along the Perivale estates often have small bathrooms and kitchens with limited or extractor-free ventilation. Everyday cooking, bathing and drying washing indoors raises humidity that has nowhere to escape, so condensation forms on cooler surfaces overnight. Mould develops around window reveals, in corners and on ceilings, especially where older metal-framed windows create cold bridging that chills the surrounding plaster.
Canal-side and Western Avenue properties
Homes closer to the Grand Union Canal and the A40 corridor sit in a naturally damper microclimate, and many have had extensions, flat-roof additions or loft conversions over the years. A past leak from a poorly maintained flat roof, gutter or pipe run often leaves hidden moisture in stud walls and behind fitted furniture, allowing mould to establish quietly in bedrooms and box rooms long before staining becomes visible.

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.
