Leak to dry to treated, one company in Cheam
Cheam's housing mix runs from 1930s bay-fronted semis and mock-Tudor detached homes near Nonsuch Park to Victorian and Edwardian villas around the conservation area and post-war flats and maisonettes towards North Cheam. Solid brick walls, original single-glazed windows and shallow lofts in the older stock trap moisture, while cavity walls in later builds are prone to bridging and penetrating damp, both feeding mould growth.

Common causes of mould in Cheam homes
Bay windows and cold bridging in Cheam's 1930s semis
Many semis around North Cheam and South Cheam have curved or square bay windows built with thin solid brickwork or poorly insulated cavities. These areas lose heat fast, creating cold spots where warm, moist household air condenses. Black mould typically appears on the reveals, the ceiling above the bay and in the corners of the room, worsening through autumn and winter when heating patterns change.
Victorian and Edwardian villas with solid walls near Cheam Village
The older properties around Cheam Village and the conservation area often have solid brick walls with no cavity, relying on breathable lime plaster that many have covered with modern gypsum and vinyl paint. This traps moisture inside the wall, leading to penetrating damp and mould staining on chimney breasts, behind wardrobes and along skirting boards, especially where pointing or render has failed.
Flats and maisonettes with limited ventilation towards North Cheam
The 1960s and 1970s flats and maisonette blocks towards North Cheam and Sutton Common were built with minimal trickle ventilation and small bathrooms that struggle to clear steam. Combined with drying laundry indoors and extractor fans that are undersized or blocked, this drives persistent condensation, leaving black mould around window frames, in bathroom corners and on north-facing bedroom walls shared with unheated stairwells.
