Leak to dry to treated, one company in Chelmsford

Chelmsford's housing spans Victorian and Edwardian terraces around Moulsham and the city centre, 1930s and post-war semis in Broomfield and Galleywood, and extensive new-build estates at Beaulieu Park and Chelmer Village. This mix of ageing lead and cast-iron plumbing, flat-roofed extensions, and densely packed modern flats above shops each brings its own hidden leak risks, from perished seals to poorly sealed bathrooms.

Areas of Chelmsford we cover

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

Common leaks in Chelmsford homes

Perished seals and failed joints in older terraces

Many Moulsham and city centre terraces still rely on original or early-replacement plumbing, where rubber washers, lead joints and soldered fittings have hardened and cracked with age. These failures often occur behind boxed-in pipework or under suspended timber floors, releasing water gradually into joists and skirting for weeks before damp patches or a musty smell give the problem away.

Flat roof leaks on Galleywood and Springfield extensions

Post-war bungalows and semis around Galleywood and Springfield frequently have flat-roofed kitchen or bathroom extensions with felt or asphalt coverings nearing the end of their working life. Splits and blistering allow rainwater to track along the roof deck and drip down internal walls far from the original leak point, often only noticed once ceiling plasterboard has already begun to sag or discolour.

Bathrooms leaking to the floor below in Beaulieu Park and Chelmer Village flats

Newer developments at Beaulieu Park and Chelmer Village include multi-storey flats and townhouses with upper-floor bathrooms directly above living space. Poorly sealed shower trays, cracked tanking or a failed waste pipe connection can send water through the floor void unnoticed, appearing as staining on a lower ceiling long after the escape of water actually began.

★★★★★

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.
