Local knowledge

What actually leaks in Dorking

Dorking sits in a gap in the North Downs where greensand meets chalk, and that boundary produces spring lines that run right through the town. A great many Dorking properties are Victorian or older with cellars, and cellar damp here is as likely to be geology as plumbing, which is exactly the question our surveys are built to answer before anyone spends money on tanking.

That is not trivia. It changes where we start. Knowing that a Dorking property is likely to be on SES 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

  • Spring-line ground water in cellars and lower ground floors
  • Victorian and older property pipework concealed in solid walls
  • Long private supply runs on hillside plots
  • Heating leaks under solid floors in period conversions
  • Chalk and greensand swallowing underground supply leaks

Every service below is available across RH4, RH5, at the same published rates we charge everywhere else.

Equipment

How we survey a property in Dorking

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.

  • High-pressure water jetting

    Water at up to 3,000 psi, fired backwards through a nozzle that drags itself up the pipe, stripping the bore back to the original clay or plastic.

  • Mechanical rodding and drain snake

    Rods and a 20-metre powered snake, for blockages close to the surface and for runs too fragile or too tight to jet.

  • Chain knocker descaling and coring

    A rotating chain head or coring machine takes off what water alone will not shift — hardened scale, set concrete and cast iron corrosion.

  • 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.

Leak detection in Dorking: your questions

How quickly can you get to Dorking?

The centre of our Surrey coverage, with same-day attendance standard. We answer the phone 24 hours a day, 7 days a week and target a 1 hour response across our coverage area,

Which parts of Dorking do you cover?

What causes most leaks in Dorking?

Dorking sits in a gap in the North Downs where greensand meets chalk, and that boundary produces spring lines that run right through the town. A great many Dorking properties are Victorian or older with cellars, and cellar damp here is as likely to be geology as plumbing, which is exactly the question our surveys are built to answer before anyone spends money on tanking. In practice that means the faults we are called to most often here are spring-line ground water in cellars and lower ground floors, victorian and older property pipework concealed in solid walls, long private supply runs on hillside plots.

Who is responsible for a leak on my supply pipe in Dorking?

Mains water in Dorking is supplied by SES 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 Dorking?

We are competitively priced and quote every job individually, the same as everywhere else we work. Call or send us the details and we will give you a price for the job before anything is booked.

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.
