Damp, mould & leak services in Highgate
Highgate's housing spans Georgian and Regency townhouses around the Village and West Hill, Victorian villas near Waterlow Park and Southwood Lane, and 1920s-30s Holly Lodge Estate mansion blocks, alongside postwar infill on the steep slopes towards Archway. Solid brick walls, ageing lead flashings, basement conversions and clay-heavy hillside ground combine to make rising damp, penetrating damp and condensation persistent issues across the area.

Common damp problems in Highgate homes
Georgian and Victorian solid-wall damp in the Village
Many Highgate Village and West Hill properties have solid brick walls with no cavity, original single-glazed sash windows and old lime or cement renders. Where cement pointing has replaced traditional lime, walls can't breathe properly, trapping moisture and causing rising or penetrating damp, flaking plaster and mould around window reveals, especially on north-facing elevations shaded by mature trees.
Hillside drainage and basement leaks
Highgate sits on London Clay across steep terrain from West Hill down to Archway, and heavy rain can overwhelm ageing surface drains and gutters. Basement and lower-ground-floor conversions common in Victorian villas near Waterlow Park and Southwood Lane are prone to lateral water penetration and rising damp where tanking has failed or was never properly installed.
Condensation and mould in flat conversions
Many of Highgate's large Victorian and Edwardian houses, plus Holly Lodge Estate mansion blocks, have been split into flats with limited cross-ventilation and older extract fans. Combined with double glazing that reduces airflow, this traps moisture from cooking and bathing, leading to black mould on cold external walls, in bedroom corners and behind wardrobes during autumn and winter months.

Service was excellent! Explained the whole process thoroughly, arrived on time when carrying out the survey. The survey was detailed and exactly what I needed for my insurance. They returned to carry out the treatment the following week. 10/10 would highly recommend.

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.
