Damp, mould & leak services in Penge
Penge's housing stock is dominated by Victorian and Edwardian terraced houses, late-Victorian purpose-built flats, and mid-twentieth century local authority blocks. Many properties retain original solid brick walls, single-glazed sash windows, and ageing slate roofs, all of which make them particularly susceptible to penetrating damp, rising damp, and condensation-related mould growth.

Common damp problems in Penge homes
Condensation and Mould in Victorian Terraces
Penge's terraced streets, particularly around Maple Road and Thicket Road, feature solid single-leaf brick walls with no cavity, meaning these properties cannot be retrofitted with standard cavity wall insulation. Heat loss through the walls is significant, creating cold internal surfaces where warm household air deposits moisture, leading to persistent black mould on bedroom walls, window reveals, and corners of ground-floor rooms.
Penetrating Damp in Older Flat Conversions
Many large Victorian villas in Penge have been converted into flats, often without adequate upgrading of the original roof, parapets, or chimney stacks. Failed lead flashings, cracked chimney haunching, and deteriorated pointing allow rainwater to track down internal walls over time. Upper-floor flats frequently show tide marks and plaster staining that owners mistake for condensation but which are actually driven by direct rainwater ingress from above.
Hidden Leaks in Post-War Council Blocks
The post-war housing blocks found near Anerley and around the borders of South Norwood present a distinct set of leak risks. Ageing communal flat-roof membranes, shared pipework chases, and deteriorating expansion joints allow water to travel considerable distances from its entry point before becoming visible. Residents often notice damp patches or bubbling paint without realising the source is a roof or pipework fault several floors or rooms away.
