Leak to dry to treated, one company in Hampstead
Hampstead's housing spans Victorian and Edwardian solid-wall terraces, grand mansion blocks around Fitzjohn's Avenue, semi-basement conversions and the Arts and Crafts homes of Hampstead Garden Suburb. Many properties retain original sash windows, thick solid brickwork and cellars, which trap moisture, restrict ventilation and make condensation, penetrating damp and mould on walls, ceilings and behind furniture common.

Common causes of mould in Hampstead homes
Solid-wall Victorian and Edwardian terraces
Much of Hampstead's terraced housing around Mansfield Road and Willow Road was built with solid brick walls rather than cavity construction, giving little insulation and allowing cold spots to form internally. Combined with double glazing retrofits that seal in moisture, this creates ideal conditions for condensation and black mould around window reveals, external corners and behind wardrobes pushed against outer walls.
Mansion block flats and communal plumbing
The large mansion blocks along Fitzjohn's Avenue and Frognal contain flats with bathrooms and kitchens often lacking effective extraction, so steam settles on tiled walls and ceilings. Shared pipework, roofs and external walls mean a leak in one flat, or a blocked communal gutter, can bring penetrating damp and mould into a neighbouring property, even where the resident's own habits are not to blame.
Arts and Crafts homes in Hampstead Garden Suburb
The tile-hung and rendered Arts and Crafts houses of Hampstead Garden Suburb often have deep roof valleys, timber casement windows and applied render that can trap water against the brickwork behind. Once render or pointing fails, moisture tracks inward and appears as mould in lofts, around dormer windows and behind fitted wardrobes, while conservation area rules mean repairs must match original materials rather than quick modern fixes.

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.
