Leak to dry to treated, one company in Northolt
Northolt's housing stock ranges from 1930s bay-fronted semis around West End and Northolt Park to postwar council-built low-rise flats and maisonettes near the A40 corridor, plus newer infill close to the station. Solid brick walls, retrofitted cavity insulation, flat-roofed extensions and ageing single-glazed windows all combine to trap moisture, making mould a recurring problem across the area's older properties.

Common causes of mould in Northolt homes
Interwar semis with retrofitted insulation
Many of Northolt's 1930s semi-detached houses around West End and Northolt Park have had cavity wall or internal insulation added over the decades without proper attention to ventilation. This traps warm, moist air against colder external walls, and we regularly find black mould developing behind wardrobes and beds pushed against outer bedroom walls, plus staining creeping across ceilings in loft-adjacent rooms.
Ex-council flats and maisonettes
The low-rise council-built blocks and maisonettes scattered through Northolt and neighbouring Yeading often have small bathrooms and kitchens with limited or failed extractor fans, single-glazed windows and thin partition walls. Steam and everyday moisture have nowhere to escape, so condensation mould spreads across window reveals, tiled splashbacks and bathroom ceilings, frequently returning within weeks unless the underlying ventilation is fixed rather than just cleaned.
Ground floor damp near watercourses and flat roofs
Properties close to the Yeading Brook and the Grand Union Canal, along with houses fitted with flat-roofed rear extensions common across Northolt, are prone to penetrating damp from ground water, failed roof coverings or blocked gutters. This shows up as black mould creeping up skirting boards, around window frames and across ceilings below flat roofs, and it keeps recurring until the actual moisture source is traced and repaired.

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.
