Leak to dry to treated, one company in New Malden
New Malden's housing stock is largely 1930s semi-detached and detached homes with bay windows and solid or early cavity brickwork, alongside Victorian and Edwardian terraces near the town centre that have since been converted into flats. This mix of older masonry, single-glazed reveals and poorly ventilated conversions creates cold spots and trapped moisture, ideal conditions for black mould on walls, ceilings and around window frames.

Common causes of mould in New Malden homes
Cold bridging around 1930s bay windows
Many New Malden semis retain original bay windows with thin single-glazed frames and minimal insulation around the reveals. These become cold bridges where warm, moist household air condenses on contact, producing black mould spotting on the surrounding plaster and sills. Left untreated, it spreads along ceiling edges in adjoining bedrooms and living rooms, particularly through autumn and winter.
Loft and rear extensions trapping moisture
Popular loft conversions and rear kitchen extensions across New Malden's semis often alter airflow without adding proper extraction. Bathrooms tucked into converted lofts and new en suites frequently lack adequate ventilation, so steam and humidity linger, settling as mould on ceilings, in corners and around shower enclosures where the original design never accounted for the extra moisture load.
Damp ingress in converted terraces and flats
Victorian and Edwardian terraces near New Malden town centre, many split into flats and maisonettes, suffer from ageing brickwork, worn pointing and flat roof sections prone to penetrating damp. Combined with restricted airflow in subdivided rooms, moisture tracks through walls and behind wardrobes or sofas pushed against external walls, encouraging hidden mould growth that residents often only notice once furniture is moved.
