Leak to dry to treated, one company in Bow
Bow's housing stock ranges from Victorian and Edwardian terraces around Roman Road to 1930s tenement blocks, post-war council estates and new-build riverside flats near Fish Island and Bow Wharf. Solid-wall terraces with shallow foundations sit alongside converted flats with poor cross-ventilation, while ex-local-authority blocks often suffer thermal bridging at concrete lintels and window reveals, all of which encourage condensation and black mould.

Common causes of mould in Bow homes
Solid-wall Victorian terraces and cold-spot mould
Many Bow terraces off Roman Road and Fern Street still have solid brick walls with no cavity, so internal surfaces run cold in winter. Without adequate insulation or ventilation, warm moist air from cooking and bathing condenses on chimney breasts, external walls and behind wardrobes pushed against them, leaving black mould patches that keep returning until the underlying cold bridging and airflow are addressed.
Ex-council blocks and concrete cold bridging
Estates such as those around Bow Common and Devons Road were built with concrete panel construction and metal-framed windows that conduct heat away fast. This creates persistent cold spots at lintels, corners and reveals where mould gathers first, often in bedrooms and behind furniture pulled against external walls, regardless of how often residents wipe it away without tackling the actual heat loss.
Converted flats and bathroom extractor failures
Bow has many Victorian houses split into flats, often with bathrooms and kitchens carved into rooms lacking proper extraction or with ducting that vents into a loft rather than outside. Steam builds up, settles on tiled ceilings and window reveals, and combines with penetrating damp from ageing parapets or flat roofs on these conversions, producing mould that spreads faster than a single-household home would see.
