Leak to dry to treated, one company in Waltham Forest
Waltham Forest's housing runs from dense Victorian and Edwardian terraces around Walthamstow, Leyton and Leytonstone to 1930s semis in Chingford and Highams Park, plus a growing stock of flat conversions and ex-council blocks. Solid brick walls, minimal loft insulation and homes split into multiple flats leave little room for moisture to escape, so condensation and black mould are a routine call-out across the borough.

Common causes of mould in Waltham Forest homes
Solid-wall Victorian terraces and cold-bridging mould
Much of Walthamstow, Leyton and Leytonstone was built with solid, uninsulated brick walls that lose heat quickly and stay cold to the touch. Warm, moist household air condenses on these cold surfaces overnight, seeding black mould in bedroom corners, behind wardrobes and along external party walls. Without insulation or ventilation improvements, spores return within weeks of any surface clean.
Poorly ventilated flat conversions
Many terraced houses across E17 and E10 have been split into flats, often with bathrooms and kitchens carved out of rooms that were never designed for extraction. Steam from showers and cooking has nowhere to go, settling on ceilings and tiled walls as persistent black mould. Shared lofts and party walls can also let moisture migrate between flats, so one household's damp becomes a neighbour's mould problem.
1930s semis with penetrating damp around windows
The inter-war semis common in Chingford, South Chingford and Highams Park often retain original window reveals, solid ground floors and ageing pointing that let rainwater track inward during wet spells. This penetrating damp shows up as mould blooming around window frames, skirting boards and beneath sills. Treating the mould alone rarely works here; the render, pointing or window seals need repair to stop water re-entering the wall.
