Leak to dry to treated, one company in Egham

Egham's housing stretches from Victorian and Edwardian terraces around the town centre and Egham Hythe to interwar semis, 1960s and 70s estates near Runnymede, and later developments close to Royal Holloway and the M25. This mix means ageing lead and cast iron plumbing sits alongside flat-roofed extensions and converted properties, both prone to hidden leaks that spread quietly through floors and party walls before they are noticed.

Common leaks in Egham homes

Older terraces near Egham Hythe and the town centre

Many Victorian and Edwardian terraces close to Egham Hythe and the High Street still run original or early-replacement plumbing beneath suspended timber floors. Joints in old pipework corrode and seep slowly, soaking joists and floorboards long before a stain appears on the ceiling below, often only discovered once flooring feels soft or a musty smell develops.

Flat-roofed extensions on interwar and post-war homes

The semis and estate housing built around Egham from the 1930s through to the 1970s frequently gained flat-roofed kitchen or bathroom extensions in later decades. Felt and asphalt coverings on these roofs perish with age and UV exposure, allowing rainwater to track along timbers and enter ceiling voids well away from the original defect, making the leak source hard to pinpoint.

Converted flats and student lets near Royal Holloway

Properties subdivided into flats around Englefield Green and near the university host shared bathrooms stacked above living space below. Failed shower tray seals, cracked grout and worn silicone let water escape gradually into the floor void, seeping into the ceiling of the flat underneath and causing damage that tenants and landlords often only spot once plaster has already softened.

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.
