Leak to dry to treated, one company in Ewell

Ewell's housing stock spans 1930s semis and bay-fronted terraces around the village, post-war estates towards West Ewell and Ewell Court, and later infill closes near Stoneleigh and Nonsuch Park. This mix means original clay soil pipes, ageing flat-roofed extensions and bathrooms retrofitted above ground-floor rooms sit alongside newer conversions, all prone to hidden leaks as seals, joints and roof coverings age at different rates across the borough.

Common leaks in Ewell homes

Flat-roofed extensions and garages

Many Ewell semis, particularly around West Ewell and Ewell Court, gained rear kitchen or utility extensions with flat roofs during the 1960s and 1970s. Felt or asphalt coverings degrade quietly, letting water track along joists and down internal walls long before a ceiling stain appears, often surfacing only once timber has started to soften.

Upstairs bathrooms above living rooms

In the bay-fronted terraces near Ewell Village and the semis around Stoneleigh and Nonsuch Park, bathrooms were frequently added above ground-floor rooms rather than built in from the start. Perished shower tray seals, cracked grout or a failed bath sealant can send water into the floor void, reaching the ceiling below days after the leak actually begins.

Ageing supply and waste pipework

Homes around Cuddington, Ruxley and Kingston Road often retain original or partially updated copper and lead plumbing runs beneath floors and behind boxed-in ducts. Corroded joints or perished washers cause slow, escape of water that seeps into subfloor insulation and skirting, frequently detected only once flooring lifts or a musty smell develops.

★★★★★

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.
