Leak to dry to treated, one company in New Malden

New Malden's housing stock is largely 1930s semi-detached and terraced homes built during the suburb's interwar expansion, alongside postwar flats around the Cambridge Road Estate and newer apartment blocks near the station. This combination of original plumbing runs, flat-roofed rear extensions and bathrooms added above older ceilings gives hidden leaks plenty of routes into the fabric of these homes.

Areas of New Malden we cover

We attend leaks right across New Malden and its neighbourhoods, including:

Common leaks in New Malden homes

Flat-roofed rear extensions

Many New Malden semis have had kitchens or bathrooms extended out back beneath a flat roof, a common alteration from the 1960s onward. The felt or asphalt covering perishes with age and sunlight, letting rainwater seep in slowly. Because the leak tracks sideways along joists before showing, staining often appears on a ceiling well away from the actual failure point, delaying discovery.

Upstairs bathrooms leaking to rooms below

Where loft conversions or side extensions have added a second bathroom above an existing ceiling, shower trays and bath seals are under constant use. Once the silicone or tanking perishes, water can pass through the floor for weeks before a stain or sagging plaster appears downstairs, often affecting kitchen ceilings in these extended interwar properties.

Ageing pipework in older suburban homes

New Malden's stock of 1930s houses still contains original or long-serving copper and lead plumbing beneath suspended timber floors. Corroded joints and pinhole leaks in these hidden runs can go unnoticed for a long time, gradually soaking floor timbers and skirtings. In the area's postwar flats, shared risers and stacks add a further source of escape of water between neighbouring properties.

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.
