Quick answer: If you have a suspected water leak at a property in Slough, our specialists trace the source without tearing the place apart, using thermal, acoustic and tracer-gas methods. A leak is not over when the water stops. Mould can start within 48 hours, so we find the source, dry the structure and treat any mould, all with one company. Leak detection is a fixed £650, usually carried out within 3 to 5 working days. Urgent same-day or next-day leak detection adds £200 on a weekday, or £300 in the evening, on a Saturday or a Sunday, making it £850 or £950 in total. Call 020 3051 8478.

Leak to dry to treated, one company in Slough

Slough's housing stock ranges from Victorian terraces in Chalvey and interwar semis around Cippenham and Upton to postwar council estates in Britwell and the flats and maisonettes built during the town's industrial expansion. More recently, high-density apartment blocks have risen near the regenerated town centre and railway corridor. This mix of ageing pipework, flat-roofed extensions and stacked flats sharing plumbing risers means hidden leaks are a persistent problem across the borough.

Common leaks in Slough homes

Flat roofs on extensions and industrial-era conversions

Many Slough properties, particularly semis in Cippenham and Upton extended during the postwar boom, have flat-roofed kitchens or bathrooms with felt or asphalt coverings that degrade unseen. Perished membranes let rainwater track along joists and settle in ceiling voids, often showing up as a damp patch weeks after the roof itself actually failed.

Bathrooms leaking through to the flat below

Slough has a substantial number of maisonettes and converted flats, including stock around Chalvey and Langley, where bathrooms sit directly above a neighbour's ceiling. A failed shower tray seal or cracked tile grout allows water to seep through the floor void, causing staining and sagging plasterboard in the property below long before residents upstairs notice anything wrong.

Perished seals and pipework in older semis and estates

Britwell and parts of Wexham contain council-era homes now several decades old, where original stopcocks, tank connections and pipe joints have perished with age. Escape of water from these failed seals often runs behind skirting boards or under suspended timber floors, leaving damp smells and warped flooring as the first visible signs of a leak that began much earlier.

Rated 5.0 / 5 based on 20 reviews on
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.
