Local knowledge
What actually leaks in Leatherhead
Leatherhead straddles the Mole, and the flood plain either side of the river means several parts of town carry a genuine seasonal ground water risk that presents identically to a leak. Toward Fetcham and Oxshott the properties get much larger, with pools, annexes and irrigation on long private runs, and there a jump in consumption is more often outside the house than inside it.
That is not trivia. It changes where we start. Knowing that a Leatherhead property is likely to be on SES Water and 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
- River Mole flood plain ground water mimicking a leak
- Long private supply runs to annexes and outbuildings
- Swimming pool and irrigation losses on larger plots
- Underfloor heating leaks in remodelled family houses
- Cellar and basement ingress near the river

Equipment
How we survey a property in Leatherhead
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 Leatherhead?
Leatherhead straddles the Mole, and the flood plain either side of the river means several parts of town carry a genuine seasonal ground water risk that presents identically to a leak. Toward Fetcham and Oxshott the properties get much larger, with pools, annexes and irrigation on long private runs, and there a jump in consumption is more often outside the house than inside it. In practice that means the faults we are called to most often here are river mole flood plain ground water mimicking a leak, long private supply runs to annexes and outbuildings, swimming pool and irrigation losses on larger plots.
Who is responsible for a leak on my supply pipe in Leatherhead?
Mains water in Leatherhead is supplied by SES Water and 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 Leatherhead?
The same as everywhere else we work — there is no Leatherhead 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.
