Leak to dry to treated, one company in Winchmore Hill
Winchmore Hill's housing stock is dominated by Victorian and Edwardian bay-fronted terraces around the Green and conservation area, alongside 1930s semi-detached houses on the roads towards Grange Park and Bush Hill Park. Solid brick walls, original single-glazed sash windows and older flat roofs on rear additions struggle to manage moisture, leaving many homes prone to condensation and penetrating damp that develops into mould.

Common causes of mould in Winchmore Hill homes
Bay windows and sash frames trapping condensation
Many Winchmore Hill terraces retain original bay windows and timber sash frames, which are prone to draughts yet still restrict airflow compared with modern glazing. Moisture from cooking, bathing and drying clothes condenses on the cold glass and surrounding reveals overnight, feeding black mould along frames, sills and the plaster returns beside the bay, particularly in north-facing front rooms.
Solid brick walls without cavity insulation
Pre-1930s properties around the Green and Broomfield Park were built with solid, uninsulated brick walls that hold the cold close to internal plaster. Warm, moist household air meets these cold surfaces and condenses, producing persistent black mould patches on external walls, in corners and behind wardrobes pushed against outside walls, especially in bedrooms that are heated less than living areas.
Rear extension flat roofs and past leak damage
Many semi-detached and terraced homes towards Bush Hill Park and Grange Park have single-storey rear extensions with flat roofs above kitchens and bathrooms. Ageing felt or asphalt coverings are prone to slow leaks that soak into ceiling plasterboard unnoticed, leaving damp patches that develop mould long after the original leak, often reappearing in the same spot until the roof covering and any hidden timber are properly repaired.

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.
