Leak to dry to treated, one company in Wandsworth
Wandsworth's housing stock ranges from dense Victorian terraces in Tooting and Balham to 1930s semis in Southfields, converted flats near Wandsworth Common and post-war estates such as Roehampton's Alton Estate. Solid brick walls, single-glazed windows and bathrooms without extraction leave many homes prone to condensation, while ageing pointing and flat roofs allow penetrating damp that feeds black mould.

Common causes of mould in Wandsworth homes
Condensation Mould in Victorian Terraces
Many of Wandsworth's Victorian terraces in Tooting, Balham and Earlsfield have solid brick walls with no cavity insulation, so bedrooms and bathrooms lose heat quickly and warm moist air condenses on cold surfaces. Without working extractor fans, black mould spreads across bathroom ceilings, around single-glazed sash windows and behind wardrobes and beds pushed against external walls, particularly in north-facing rooms that rarely get direct sunlight.
Penetrating Damp in Converted and Basement Flats
Wandsworth has large numbers of Victorian and Edwardian houses split into flats, with basement and lower ground floor conversions common around Earlsfield, Southfields and Wandsworth Town. Cracked render, blocked gutters and damp proof courses bridged by raised garden levels let water penetrate solid walls, leaving damp patches near skirting boards and mould growing behind sofas, beds and fitted furniture pushed against affected walls where air cannot circulate.
Leak-Related Mould in Flats and New Riverside Developments
Post-war estates around Roehampton and newer riverside apartment blocks near Nine Elms and Battersea bring different problems. Concrete construction and thermal bridging around window reveals cause persistent cold spots and mould, while sealed double glazing with limited trickle ventilation traps moisture indoors. A leaking roof, overflowing gutter or burst pipe in the flat above can also leave hidden mould growing behind plasterboard and skirting after the original leak is repaired.

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.
