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.

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.
