Local knowledge
What actually leaks in Kingston upon Thames
Kingston sits on Thames gravels with a water table that responds quickly to the river, and riverside properties at Kingston and Surbiton regularly present with basement and ground floor moisture that is seasonal rather than plumbing. Surbiton's large Victorian villas, mostly converted to flats, supply the other half of the workload.
That is not trivia. It changes where we start. Knowing that a Kingston upon Thames 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
- Thames-influenced seasonal ground water in basements
- Escape of water between flats in Surbiton villa conversions
- Shallow supply pipes in gravel subsoil
- Heating leaks under solid floors in interwar New Malden housing
- Rear extension and side return junction leaks

Equipment
How we survey a property in Kingston upon Thames
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 Kingston upon Thames?
Kingston sits on Thames gravels with a water table that responds quickly to the river, and riverside properties at Kingston and Surbiton regularly present with basement and ground floor moisture that is seasonal rather than plumbing. Surbiton's large Victorian villas, mostly converted to flats, supply the other half of the workload. In practice that means the faults we are called to most often here are thames-influenced seasonal ground water in basements, escape of water between flats in surbiton villa conversions, shallow supply pipes in gravel subsoil.
Who is responsible for a leak on my supply pipe in Kingston upon Thames?
Mains water in Kingston upon Thames 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 Kingston upon Thames?
The same as everywhere else we work — there is no Kingston upon Thames 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.
