Damp, mould & leak services in Nunhead

Nunhead's housing stock is dominated by dense Victorian terraces built from the 1870s onwards as the railway opened the area up, many now split into flats, alongside Edwardian villas near the park, postwar council infill and 1930s semis on the steeper slopes towards Brockley. Solid brick walls, ageing render and original single-glazed sashes leave much of this stock prone to damp, penetrating water and condensation.

Common damp problems in Nunhead homes

Rising damp in solid-wall Victorian terraces

Many Nunhead terraces off Evelina Road and Ivydale Road were built with little or no functioning damp-proof course, and decades of raised garden levels and cement render have since bridged what DPC exists. Ground floor rooms and converted lower-ground flats commonly show tide-marked plaster, crumbling skirting and salt staining, worsened by the clay subsoil that holds water against foundations after heavy rain.

Flat roof and loft conversion leaks

Loft extensions are widespread across Nunhead's terraced streets, giving extra bedrooms but often built with ageing felt flat roofs over dormers and rear additions. These frequently fail at flashing junctions and roof lights, letting water track down into insulation and ceilings below. Poor ventilation in these converted lofts also encourages condensation and mould at eaves and cold bridges around the roof timbers.

Condensation in subdivided period flats

Large Victorian houses around Nunhead Green and Gordon Road were split into flats decades ago, leaving individual units with limited through-ventilation, blocked chimneys and single-glazed sash windows. Cooking and drying laundry in these compact spaces raises humidity quickly, and mould commonly develops in bathrooms, behind wardrobes on external walls, and around window reveals where original solid brick offers little insulation.

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.
