Leak to dry to treated, one company in Clapham North
Clapham North mixes Victorian terraces converted into flats, purpose-built mansion blocks near the High Street, ex-local authority estates around Larkhall and Studley, and basement or lower-ground conversions. Solid brick walls, shared plumbing, single-glazed sash windows and dense multi-occupancy living all restrict airflow and trap moisture, making condensation and damp-related mould a recurring issue across the area's older stock.

Common causes of mould in Clapham North homes
Condensation mould in Victorian terrace conversions
Many Clapham North terraces off Clapham Manor Street and Voltaire Road were split into flats decades ago, leaving small bathrooms and bedrooms with little or no extraction. Solid brick walls have no cavity to buffer moisture, so warm, humid air condenses on cold plaster. Black mould builds up on bedroom walls, in wardrobes and behind furniture pushed against external walls, especially over winter.
Penetrating damp in basement and lower-ground flats
The lower-ground and basement flats common around Clapham Park and Larkhall sit below street level, where ageing tanking, cracked external render or leaking gutters let water penetrate solid brickwork. Once inside, damp tracks along skirting and up chimney breasts, feeding mould growth that keeps reappearing after redecoration until the actual entry point for the water is traced and sealed.
Cold bridging and window mould in mansion blocks and ex-council flats
The purpose-built mansion blocks and ex-local authority estates near the High Street and Stockwell border often have concrete floor slabs and metal or early uPVC window frames that create cold bridges. Moisture condenses fastest at these weak points, producing black mould around window reveals, in corners and along ceiling edges, particularly in flats with limited cross-ventilation between rooms.
