Leak to dry to treated, one company in Erith
Erith's housing ranges from Victorian and Edwardian terraces around the town centre to 1930s semis, post-war council estates in Northumberland Heath and new riverside apartment blocks along the Thames. This mix of solid brick walls, flat-roofed maisonettes and airtight modern flats, combined with the area's low-lying riverside position, leaves many homes prone to damp and black mould.

Common causes of mould in Erith homes
Solid-wall Victorian and Edwardian terraces
Many terraces around Erith town centre and Northumberland Heath were built with solid brick walls and no cavity, making them prone to penetrating damp and cold spots. Black mould often develops on external walls, in corners and behind wardrobes and beds where air cannot circulate. Old pointing, worn render or leaking gutters let moisture in, so treating the mould only works once the entry point is repaired.
Riverside flats and modern apartment blocks
Newer developments along Erith Riverside and near the Thames are built to be airtight, which traps moisture from cooking, showering and drying clothes indoors. Without adequate trickle vents or extraction, condensation collects on cold surfaces, particularly around windows, in bathrooms and on north-facing walls. Black mould in these flats tends to return quickly unless ventilation is improved alongside cleaning.
Post-war council estates and flat-roofed maisonettes
Estates such as those around Northumberland Heath and Slade Green include maisonettes and low-rise blocks with flat roofs, which are prone to slow leaks that soak into ceilings and roof-facing bedrooms. Combined with poorly insulated solid walls, this creates damp patches and mould that spreads across ceilings and behind furniture, often mistaken for simple condensation until the roof or flashing is properly inspected.

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.
