Leak to dry to treated, one company in Potters Bar
Potters Bar mixes 1930s bay-fronted semis around Mutton Lane and Little Heath, ex-council flats and maisonettes near Darkes Lane, and older cottages around South Mimms and Mimms Hall, alongside newer developments at Oakmere Park. Heavy Hertfordshire clay subsoil, solid pre-war walls, flat-roofed extensions and dense post-war infill combine to trap moisture and push condensation mould into poorly ventilated rooms.

Common causes of mould in Potters Bar homes
Condensation mould in 1930s semis
The bay-windowed semis around Little Heath and Mutton Lane were built with single-skin bay fronts and small original chimneys that have often been sealed. Without that natural airflow, moisture from cooking, bathing and drying washing collects on cold external walls and around window reveals, leaving black speckled mould on bedroom corners and behind wardrobes pushed against outside walls.
Penetrating damp in older cottages
Around South Mimms and Mimms Hall, older brick and render cottages rely on solid walls rather than cavities. Cracked pointing, worn render and ageing gutters let rainwater soak through, and the moisture tracks inward to appear as mould on internal plaster, chimney breasts and ceilings below leaking valleys, often worsening through Hertfordshire's wetter winter months.
Flat-roof leaks in ex-council flats and maisonettes
Post-war flats and maisonettes near Darkes Lane and Southgate Road frequently have flat-roofed extensions, kitchens or bathrooms with ageing felt coverings. Slow leaks at joints and upstands go unnoticed until mould develops on ceilings and top-floor walls, while small bathrooms with no extractor fan add further condensation, leaving black mould around windows and grout that returns quickly if the roof is not repaired.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
