We start with a damp and mould survey (£500) to find the cause, then treat the mould and fix the source. Call 020 3051 8478.

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.

Tip: Wiping mould off with bleach and repainting hides it for a few weeks, then it returns. Mould is a moisture problem, so unless the condensation, damp or leak feeding it is fixed, it always comes back.

Frequently asked questions

How much does mould removal in Neasden cost?
It depends on the cause and extent. We start with a damp and mould survey at £500 to find the moisture source, then quote the treatment. Treating the surface without the source means the mould returns.
Is black mould in my home dangerous?
Black mould affects indoor air quality and is best removed promptly. We treat the mould and fix the moisture driving it, so the problem is dealt with at the cause.
Will the mould come back after treatment?
Not if the moisture source is fixed. We find and address the cause, whether condensation, penetrating damp or a leak, rather than just cleaning the surface.
Do you find what is causing the mould?
Yes. Every job starts by identifying why the mould is there, using a proper damp and mould survey, so the treatment lasts.
