Damp, mould & leak services in Dulwich

Dulwich's housing runs from Georgian and early Victorian villas around Dulwich Village to dense Victorian and Edwardian terraces off Lordship Lane, plus 1930s semis towards West Dulwich and postwar infill near Sydenham Hill. Much of the older stock sits within the Dulwich Estate's conservation controls, meaning solid brick walls, original sash windows and ageing roofs are often repaired piecemeal rather than upgraded, leaving damp, condensation and slow leaks to take hold unnoticed.

Common damp problems in Dulwich homes

Solid-wall damp in Dulwich Village terraces

Georgian and Victorian properties around Dulwich Village and College Road were built with solid brick walls rather than a cavity, so moisture can move straight through the masonry. Raised flowerbeds, resurfaced pavements and old render often bridge the damp-proof course, drawing rising and penetrating damp into skirtings and plaster. Because many facades sit within the conservation area, repairs must use breathable, sympathetic materials rather than modern sealants that trap moisture in.

Basement and lower-ground conversions in East Dulwich

The long Victorian terraces off Lordship Lane and around Goose Green have seen extensive lower-ground floor conversions to add kitchens and bedrooms. Where tanking or waterproof membranes were poorly installed or joined badly with the original solid walls, lateral damp pushes through at skirting level after heavy rain. Combined with limited ventilation in these dug-out spaces, condensation and black mould around external walls and window reveals are a recurring complaint.

Flat roof and rear extension leaks near Peckham Rye and Nunhead

Many East Dulwich and Nunhead terraces have single-storey rear extensions with flat felt or GRP roofs added over the decades, often abutting older brickwork with mismatched flashing. Ponding water and perished roof coverings let moisture track into ceiling joists and internal walls, showing up as staining or mould well away from the actual leak. Cast iron guttering on unmodernised Victorian properties nearby adds further risk where joints have corroded.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. An assessment that finds the source first saves paying for the same repair twice.
