Leak to dry to treated, one company in Windsor

Windsor's housing stock ranges from Georgian and Victorian terraces near the castle and river to 1930s semis in Clewer and Dedworth, plus newer flats built close to the Thames floodplain. This mix of aged plumbing, converted period properties, flat-roofed extensions and riverside developments creates varied vulnerabilities, from old lead and cast iron pipework to modern seals under constant damp pressure from groundwater.

Common leaks in Windsor homes

Ageing pipework in period conversions

Many Windsor terraces near the town centre and Clewer Village have been split into flats, with plumbing runs added decades apart. Joints hidden behind boxed-in walls or under floorboards can fail slowly, releasing water into voids where it tracks along joists before showing as a ceiling stain in the flat below, often long after the leak actually started.

Flat roofs on rear extensions

Rear kitchen and bathroom extensions are common across Dedworth and Old Windsor, many finished with felt or GRP flat roofs. Perished membranes and blocked outlets let rainwater seep through insulation and plasterboard gradually, so damage often appears well away from the actual defect, making the source hard to trace without opening up the ceiling void.

En-suite and bathroom escapes of water

Homes near Windsor Great Park and riverside developments frequently have upper-floor en-suites added during renovation. Perished tray seals, grout and shower screens allow water to escape steadily rather than as a sudden flood, soaking into subfloors and travelling to the room below, where damp patches and swollen skirting boards are usually the first visible sign.

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.
