Leak to dry to treated, one company in Tolworth

Tolworth's housing stock is dominated by 1930s semi-detached and terraced homes built during the suburb's interwar expansion along the Kingston bypass, alongside postwar flats around Tolworth Tower and Broadway. Many semis carry flat-roofed rear extensions housing kitchens or bathrooms, while older pipework and single-glazed seals sit hidden behind decades of subsequent renovation, making concealed leaks common.

Common leaks in Tolworth homes

Flat-roofed extensions on 1930s semis

A large share of Tolworth's semi-detached homes gained flat-roofed kitchen or bathroom extensions during the mid to late twentieth century. Felt or asphalt coverings degrade with age and weather cycling, and once the membrane splits, water tracks along joists before showing as a ceiling stain, often weeks after the roof itself first failed.

Bathrooms leaking into rooms below

In Tolworth's two-storey semis and the flats around Tolworth Tower and St Mark's, first-floor bathrooms sit directly above kitchens or living rooms. Perished sealant around baths and shower trays, or a cracked waste pipe joint under the floor, lets water travel silently through joists and insulation, surfacing later as damp patches or a sagging ceiling below.

Ageing pipework and perished seals

Many Tolworth properties still run original or early-replacement plumbing installed decades ago, with compression joints and rubber seals that harden and crack over time. Escape of water from these fittings frequently runs beneath suspended timber floors or within stud walls, going unnoticed until skirting boards swell or flooring starts to lift.

What our customers say

★★★★★

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.

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.
