Leak to dry to treated, one company in Sutton

Sutton's housing spans 1930s semis around Cheam and Belmont, Edwardian terraces near the town centre, post-war estates in Rosehill and Benhilton, and denser flat conversions close to the station. This mix means ageing lead and copper pipework sits alongside flat-roofed extensions and converted bathrooms, all prone to hidden leaks as original plumbing and seals age past their intended lifespan.

Areas of Sutton we cover

We attend leaks right across Sutton and its neighbourhoods, including:

Common leaks in Sutton homes

Flat-roofed extensions and rear additions

Many Sutton and Cheam semis gained flat-roofed kitchen or bathroom extensions during the 1970s and 1980s. These roofs rely on felt or asphalt coverings that degrade with age, allowing water to track along joists and emerge as staining well away from the original entry point, often mistaken for condensation until ceilings begin to sag.

Upstairs bathrooms leaking into rooms below

Terraced and semi-detached homes in Carshalton and Wallington frequently had bathrooms added above kitchens or living rooms. Perished shower tray seals, cracked grout or a failed waste pipe joint can send water seeping through the floor structure for weeks, showing up as bulging plaster, discoloured ceiling roses or a musty smell downstairs.

Ageing pipework in older converted properties

Edwardian and interwar houses around Sutton Common and Benhilton, many since converted into flats, often retain original or mid-century plumbing runs hidden within solid walls and under floorboards. Corroded joints or split copper pipes can leak slowly behind skirting for months, causing rot and mould before any damp patch becomes visible on the surface.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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.
