Leak to dry to treated, one company in Dollis Hill
Dollis Hill is built largely around 1930s bay-fronted semis and interwar terraces climbing towards Gladstone Park, alongside mansion blocks near the tube and low-rise ex-council flats further out. Original solid brick sections, ageing flat-roofed rear extensions, and poorly ventilated converted flats all combine to trap moisture, making mould a recurring issue across the area's varied housing.

Common causes of mould in Dollis Hill homes
Flat-roofed extensions and box gutters on Dollis Hill semis
Many 1930s semi-detached houses around Dollis Hill have had kitchen or bathroom extensions added with flat felt roofs and box gutters that fail quietly over years. Water tracks along ceiling joists into the bedroom above or the party wall, appearing as black mould on ceilings and upper walls long before any leak is obvious, often worsened once cooler weather sets in.
Condensation mould in Dollis Hill's mansion blocks and flat conversions
The mansion blocks near Dollis Hill station and the many houses split into flats along Dollis Hill Lane and Anson Road often lack effective bathroom or kitchen extraction. Cooking and showering push moisture into rooms with limited through-draught, settling on cold external walls and behind wardrobes pushed against unheated corners, producing persistent black spotting that returns quickly after cleaning.
Cold bridging in Dollis Hill's postwar flats and maisonettes
The low-rise concrete flats and maisonettes around Gladstone Park and the estates towards Neasden Lane suffer from thin window reveals and minimal wall insulation, creating cold bridges where warm indoor air condenses fastest. Mould gathers in corners, around window frames and above skirting boards in bedrooms, a pattern that reappears each winter unless the underlying heat loss and ventilation are addressed together.

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.
