Leak to dry to treated, one company in Morden
Morden's housing runs from 1930s semis and the sprawling St Helier cottage estate to postwar terraces and newer flats around the town centre and Morden Hall Park. Solid-walled interwar stock, retrofitted cavity insulation and poorly ventilated bathrooms in converted properties all combine to trap moisture, making condensation and black mould persistent problems across the area.

Common causes of mould in Morden homes
St Helier estate cottage homes and penetrating damp
Many St Helier estate cottages still have original solid brick walls, ageing render and pointing that has worn thin over decades. Where rainwater gets past the external finish, it tracks through the wall and appears as black mould patches on internal chimney breasts and corner walls, often mistaken for condensation when the real cause is water entering from outside.
1930s semis with retrofitted cavity insulation
Semi-detached homes across Lower Morden and Morden Park were built with simple cavity walls that many owners later filled with insulation to cut heating bills. Without adequate ventilation to match, warm moist air condenses on cold spots and bridges, producing recurring mould in bedroom corners, behind wardrobes and along external walls that repainting alone never resolves.
Flats and conversions with poor bathroom extraction
Converted houses and newer flats near Morden town centre and South Wimbledon frequently rely on undersized or poorly ducted extractor fans. Steam from bathrooms drifts into hallways and adjoining bedrooms, settling on ceilings and behind furniture pushed against external walls, leading to black mould that returns quickly unless the ventilation and moisture source are properly addressed.

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.
