Damp, mould & leak services in Nunhead

Nunhead is dominated by tightly packed Victorian and Edwardian terraces, many converted into flats, alongside interwar housing and postwar council blocks near Nunhead Green. Original single-brick walls, shared party structures and ageing lead or cast iron plumbing common to these conversions make undetected escapes of water between floors a frequent problem, especially where bathrooms have been retrofitted above original ground floor rooms.

Common leaks in Nunhead homes

Converted terraces with stacked bathrooms

Many Nunhead terraces were split into flats decades ago, with bathrooms added directly above kitchens or living rooms below. Waste pipework and shower trays fitted into these retrofits often lack proper tanking, so water tracks silently through joists and ceiling voids for months. Residents typically only notice a leak once staining or sagging plaster appears on the floor below, by which point joists and lath can already be affected.

Flat and mansard roofs on period stock

Rear extensions and loft conversions across Nunhead's Victorian streets frequently use flat or shallow-pitched felt roofs that perish faster than the original slate above. Perished felt, cracked flashing around chimneys and blocked outlets let rainwater in gradually rather than in an obvious deluge, so it soaks into insulation and ceiling timbers unnoticed until a bedroom ceiling below finally darkens or bulges.

Ageing seals and shared plumbing runs in older properties

Properties around Nunhead Green and the older ex-council blocks often retain original or long overdue bathroom seals, mixer valves and soil stack joints. Once silicone perishes or a stack joint loosens, water can travel along floor voids and shared party walls before surfacing, meaning the visible damp patch is rarely directly beneath the actual failed seal or pipe.

What our customers say

Excellent
Rated 5.0 / 5 based on 22 reviews on
Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
