Leak to dry to treated, one company in Neasden
Neasden's housing runs from 1930s bay-fronted semis and terraces around Neasden Lane and Church Road to ex-local authority low-rise blocks near Tanfield Avenue and post-war conversions towards Dollis Hill. Solid brick walls without cavities, single-glazed original windows and flat-roofed rear extensions are common, and combined with limited through-ventilation this housing mix is particularly prone to condensation and damp-related mould.

Common causes of mould in Neasden homes
Solid-wall semis and cold bridging
Many of Neasden's 1930s semis and terraces were built with solid brick rather than cavity walls, so internal surfaces stay cold in winter. Moist air from cooking, bathing and drying clothes condenses on these cold spots, particularly north-facing bedroom walls and bay window reveals, producing recurring black mould that returns each heating season unless the underlying cold bridging and ventilation are addressed rather than just the visible staining.
Ex-council flats and bathroom ventilation
The low-rise ex-local authority blocks around Neasden Lane and Tanfield Avenue often have concrete construction, older extractor fans and shared corridors that trap humidity. Bathrooms and box bedrooms in these flats regularly develop mould around window frames and behind wardrobes pushed against external walls, since airflow is restricted and residual moisture has nowhere to escape, allowing spores to establish quickly in these confined, poorly aired spaces.
Flat roofs and penetrating damp in converted terraces
Terraced houses converted into flats towards Willesden Green and Dollis Hill frequently carry flat-roofed rear additions and older parapet gutters that are prone to slow leaks. Water tracking down inside the wall cavity or ceiling void shows up later as mould blooms around windows or in top-floor bedrooms, often mistaken for simple condensation when the real cause is a defect in the roof or flashing that keeps feeding moisture into the structure.

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.
