Leak to dry to treated, one company in Hornsey
Hornsey's housing stock is dominated by Victorian and Edwardian terraces and semis, many carved into flats, alongside interwar semis near Priory Park and postwar blocks around Turnpike Lane. Solid brick walls, single-glazed sash windows and cramped converted bathrooms combine to trap moisture, making condensation, penetrating damp and mould around windows and in bathrooms a recurring problem.

Common causes of mould in Hornsey homes
Solid-wall Victorian terraces and condensation mould
Much of Hornsey's terraced housing around Rokesly and Hornsey Vale was built with solid brick walls and no cavity, so internal surfaces run cold in winter. Warm, moist air from cooking, bathing and drying laundry indoors condenses on these cold walls and single-glazed window reveals, leaving black mould around frames, in corners and on ceilings, especially in bedrooms with limited airflow.
Converted flats with poorly ventilated bathrooms and kitchens
Many large Hornsey houses near Crouch End and Middle Lane were split into flats decades ago, often leaving bathrooms and kitchens without external walls or working extractor fans. Steam has nowhere to escape, so mould spreads across ceilings, tile grout and behind wardrobes pushed against external walls, while ground-floor and lower-ground flats also face penetrating damp through ageing solid walls and neglected guttering.
Ex-local authority blocks and cold bridging near Turnpike Lane
Postwar and 1960s-70s blocks around Turnpike Lane and Wood Green were built with concrete panels and minimal insulation, creating cold bridges at corners, window lintels and behind fitted furniture. Residents heating only living areas leave bedrooms noticeably colder, so moisture condenses overnight and mould takes hold behind beds and wardrobes, often mistaken for a leak until the moisture source is properly traced.
What our customers say
I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.
