Local knowledge
What actually leaks in Ewell
Ewell and Stoneleigh are overwhelmingly 1930s suburban semis built in a single wave, which means an entire district reaching the same point in the life of its plumbing at the same time. The original galvanised and lead supply pipework in these houses is now ninety years old, and pinhole failures where it runs through or under the solid ground floor are the routine call from this area.
That is not trivia. It changes where we start. Knowing that a Ewell property is likely to be on Thames Water mains, built the way most of the stock around it was built, and sitting on the ground it sits on, means we can rule out whole categories of fault before we unpack the van — which is time you are not paying for.
The faults we are called to most often here
- Ninety-year-old galvanised and lead supply pipework failing
- Leaks beneath 1930s solid ground floors
- Original bay window and flat roof detailing letting water in
- Heating pipework buried during 1970s installations
- Drain cracks under mature street trees

Equipment
How we survey a property in Ewell
Every van carries the full range. Which instrument leads depends on the pipe, the pressure and the ground it is buried in.
Thermal imaging camera survey
A radiometric camera reads surface temperature through plaster, screed and tile to reveal the cold plume of an escaping supply pipe or the warm track of a heating leak.
Acoustic leak correlation
Ground microphones and digital correlators listen for the specific hiss of pressurised water forcing its way out of a pipe, then triangulate the exact point.
Tracer gas testing
A harmless hydrogen and nitrogen mix is introduced into drained pipework, escapes at the fault, and is picked up at the surface by a gas sensor.
Moisture mapping and salts analysis
Pin and pinless meters chart how wet a structure is, and a salts test tells us whether the water arrived from a pipe, from the ground, or from the weather.
Pressure and flow testing
Isolating and pressurising each circuit in turn proves which one is losing water, and how fast, before anything is opened up.
CCTV drainage survey
A self-levelling camera crawls the drain run and records exactly what is broken, where it is, and how deep.
Borescope inspection
A camera on a flexible probe goes through a hole the size of a pencil to look inside a void, wall or ceiling.
Tracer dye testing
Non-staining fluorescent dye is added to one water source at a time so the escaping water carries a colour-coded label.
Pipe and cable tracing
A signal generator puts a tone on the pipe and a receiver follows it, so we map the route and depth before anyone digs.
Roof integrity and voltage testing
Low-voltage electronic testing finds breaches in a flat-roof membrane that are invisible from the surface.

What causes most leaks in Ewell?
Ewell and Stoneleigh are overwhelmingly 1930s suburban semis built in a single wave, which means an entire district reaching the same point in the life of its plumbing at the same time. The original galvanised and lead supply pipework in these houses is now ninety years old, and pinhole failures where it runs through or under the solid ground floor are the routine call from this area. In practice that means the faults we are called to most often here are ninety-year-old galvanised and lead supply pipework failing, leaks beneath 1930s solid ground floors, original bay window and flat roof detailing letting water in.
Who is responsible for a leak on my supply pipe in Ewell?
Mains water in Ewell is supplied by Thames Water. As a general rule the supply pipe from the boundary stop tap into your property is yours to maintain, and everything on the street side belongs to the water company. Our report states which side of that boundary the fault sits on, which matters because many water companies will repair a first leak on a customer supply pipe at no charge.
How much does leak detection cost in Ewell?
The same as everywhere else we work — there is no Ewell premium. Weekday surveys start at £54.00 + VAT with a half-hour minimum and no call-out fee, evenings and weekends from £69.75 + VAT, and late nights from £90.00 + VAT.
Will my insurer accept a leak detection report from you?
Our reports are written to the evidence standard loss adjusters work to: calibrated moisture readings, dated photographs, a stated methodology and a clear causation finding. Trace and access cover in your buildings policy will usually pay for the survey itself as well as the damage caused by getting to the leak.
