Leak to dry to treated, one company in Harlow
Harlow's housing stock reflects its origins as a 1950s-60s New Town: concrete panel system-built homes, flat-roofed maisonettes and solid-wall terraces sit alongside later estates like Bush Fair, Church Langley and Newhall. Poor cavity insulation, cold bridging through concrete panels and ageing flat roofs leave many properties prone to condensation and penetrating damp, feeding recurring mould.

Common causes of mould in Harlow homes
Concrete system-built homes and cold bridging
Harlow's 1950s and 60s neighbourhoods such as Mark Hall, Netteswell and Tye Green were built using concrete panel and prefabricated construction with minimal insulation. Thermal bridging at panel joints, lintels and window reveals leaves internal surfaces cold, so warm moist air condenses there rather than evaporating, producing black mould around window frames, in corners and along external walls even when the property is well ventilated.
Flat roofs on maisonettes and flats
Many low-rise maisonette blocks and flats across Staple Tye, Sumners and Bush Fair still carry original flat roofs and parapet gutters that were never intended to last this long. As the felt or asphalt covering ages and cracks, rainwater tracks slowly through the ceiling void, showing up as brown staining and black mould on top-floor bedroom ceilings and bathroom corners well before any leak becomes obvious inside the flat below.
Solid-wall terraces without cavity protection
Older housing in Old Harlow and Potter Street predates standard cavity wall construction, so solid brick walls draw in moisture during wet weather and are slow to dry out. Without adequate background ventilation, that moisture evaporates internally and condenses on cold plaster, wardrobes and headboards pushed against outside walls, creating hidden black mould behind furniture in bedrooms and bathrooms that residents often only notice once items are moved.
