Damp, mould & leak services in Sunbury
Sunbury's housing spans riverside Georgian and Victorian cottages around Lower Sunbury and Thameside, 1930s bay-fronted semis near Sunbury Common, post-war terraces around Green Street, and denser 1970s-90s estates and flats near Sunbury Cross and Kempton Park. Proximity to the Thames and Queen's River raises groundwater levels, while older solid-wall cottages and ageing rendered semis are prone to penetrating damp, rising damp and condensation-driven mould.

Common damp problems in Sunbury homes
Riverside cottages and rising damp
The Georgian and Victorian cottages lining Lower Sunbury and the Thames riverside were built with solid brick walls and shallow footings, with no effective damp proof course. High local groundwater and periodic river flooding push moisture up through walls and floors, causing rising damp, salt staining and skirting board decay, particularly in properties fronting Thames Street and the towpath.
1930s semis with failing rendered walls
Many bay-fronted semi-detached homes around Sunbury Common and Green Street were built with pebbledash or painted render finishes now reaching the end of their service life. Hairline cracking and blown render let rainwater track behind the coating and into cavity walls, leading to penetrating damp patches around window reveals and chimney breasts that worsen after prolonged autumn and winter rain.
Condensation and mould in flats near Sunbury Cross
Flats and maisonettes built from the 1970s onward near Sunbury Cross and Kempton Park often have limited through-ventilation, small kitchens and bathrooms without effective extraction, and double glazing that traps moisture indoors. This combination regularly produces black mould on north-facing bedroom walls, wardrobes and window reveals, especially where tenants dry washing indoors during colder months.
What our customers say
Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
