Leak to dry to treated, one company in Clapham
Clapham's housing stock is dominated by tall Victorian and Edwardian terraces, many split into flats, alongside mansion blocks, ex-council estates and a growing number of basement and loft conversions. Solid brick walls, ageing render, shared roofs and cramped bathrooms without proper extraction all combine to trap moisture, making mould a recurring problem across the area.

Common causes of mould in Clapham homes
Solid-wall Victorian terraces and penetrating damp
Much of Clapham's period housing around Clapham Old Town and Abbeville Village has solid brick walls with no cavity, so rainwater tracks through cracked pointing, worn render or defective flashing and reaches internal plaster. The result is black mould creeping across chimney breasts, external walls and ceilings below flat roofs, often mistaken for simple staining until it spreads.
Converted flats with poor bathroom and kitchen ventilation
Many Victorian houses in Clapham North and Clapham South were split into flats decades ago, leaving small internal bathrooms with weak or missing extractor fans. Steam and cooking moisture linger with nowhere to escape, settling on cold tiles, grout and ceilings. Mould builds up behind cisterns, in shower corners and along ceiling edges, returning quickly unless ventilation is properly addressed.
Basement and lower-ground conversions prone to condensation
The popularity of basement and lower-ground extensions in Clapham Park and near Wandsworth Common has created living spaces below external ground level, where warm indoor air meets cold, poorly insulated walls. Condensation forms on windows, behind wardrobes and furniture pushed against outer walls, feeding mould growth that keeps recurring until damp-proofing and airflow are corrected.
What our customers say
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.
