Quick answer: Damp & Mould Solutions UK removes and treats black mould at properties in West Dulwich, and deals with the moisture driving it rather than painting over it.

If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. Call 020 3051 8478.

Leak to dry to treated, one company in West Dulwich

West Dulwich is dominated by large Victorian and Edwardian terraces and semis around Croxted Road and Alleyn Park, alongside mansion flats near the station and 1930s houses towards Rosendale. Solid brick walls, single-glazed sashes and converted basements or loft bathrooms trap moisture, giving condensation and black mould a steady foothold across the ward.

Common causes of mould in West Dulwich homes

Bay windows and single-glazed sashes growing black spot mould

Many West Dulwich terraces retain original bay windows with single-glazed sashes and thin curtains. Cold glass and unlined reveals mean warm, moist household air condenses overnight, leaving black spot mould on frames, sills and the surrounding plaster. Left untreated it spreads to nearby wallpaper and skirting, particularly in bedrooms facing north or shaded by mature street trees.

Solid brick walls without cavity insulation losing heat to damp

Victorian and Edwardian houses off Croxted Road and Alleyn Park were built with solid brick walls, not cavities. Without external or internal insulation these walls stay cold, so moist air condenses on internal plaster in corners, behind wardrobes and along ceiling edges. The result is recurring surface mould that returns quickly after cleaning unless the underlying heat loss and ventilation are addressed.

Converted basements and loft bathrooms with poor extraction

Basement conversions and loft bathrooms added to West Dulwich's larger family houses often lack adequate mechanical extraction or rely on windows alone. Steam from showers and cooking has nowhere to escape, settling on tiled ceilings, grout and door frames. Combined with penetrating damp from ageing rendering or flat roofs, this produces persistent black mould that keeps reappearing without a proper moisture fix.

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 West Dulwich cost?
Mould treatment starts from £300, with a fixed price confirmed from photos or a short video before we attend. If the cause of the moisture is not clear, a full damp and mould survey is a separate service, £500, or £450 when you book online and pay the deposit. 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.
