    Leak Detection in Horley — Non-Invasive Surveys

    Find hidden water leaks fast in Horley — without ripping up floors, tiles or driveways.

    Non-invasive leak detection across Horley, Smallfield, Charlwood and the wider Gatwick area.

    What to do if you suspect a hidden leak

    Damp patches on a ceiling, a meter that ticks over when nothing is running, or an unexplained jump in your water bill — all classic signs of a hidden leak. In Horley the most common culprits are pinholes in old copper pipework, perished compression joints under floors, and supply-pipe leaks running between the meter and the house.

    We use acoustic listening sticks, thermal imaging cameras and pressure testing to pinpoint the leak to within centimetres before anything is disturbed. That means a targeted repair instead of ripping up an entire floor or driveway.

    If the leak turns out to be on the underground supply pipe, we can fix it in the same visit using moling — replacing the run without digging a trench across your garden or drive.

    What leak detection work in Horley actually involves

    Housing stock and why supply pipes fail in Horley

    Horley expanded heavily in the 1930s and again from the 1980s onwards around Langshott and Westvale Park. The inter-war housing on Victoria Road, Massetts Road and Meath Green is where we find most of the failing lead and galvanised supply pipes; the newer estates are usually MDPE already, and there the issue is more often a pulled or badly made joint at the boundary than pipe failure.

    Ground conditions across RH6

    Horley sits on Weald Clay with alluvium near the River Mole. The water table can be high on the western side towards Hookwood and Charlwood, so pits fill quickly. We plan for that with pumps on site rather than downing tools halfway through the day.

    Access, driveways and reinstatement

    Proximity to Gatwick means a lot of Horley properties have off-street parking laid across the whole front garden. That makes trenching disproportionately expensive to put right and makes moling the obvious choice for a supply pipe replacement.

    Water supplier and postcodes we cover

    Horley and the surrounding Surrey villages are supplied by SES Water, and the properties we work on are mainly in the RH6 postcode area. Your water supplier is responsible for the main in the road and the communication pipe up to the boundary stop tap; the supply pipe from the boundary into your home is the homeowner's responsibility, and that is the section we replace, repair and leak-locate.

    Streets and neighbourhoods we regularly work in around Horley include Smallfield, Salfords, Charlwood, Hookwood, Langshott, Meath Green and Povey Cross. If you are just outside these, it is still worth calling — most of Surrey is within our normal working radius and there is no charge for a quote.

    We aim to attend leak enquiries in Horley the same day or the next working day. We work Monday to Friday 8am–6pm and Saturday 9am–4pm, and we're based in Crawley Down, so Horley is a short drive for us.

    A standard domestic leak detection survey in Horley costs around £180–£350 and takes one to two hours on site. The price depends on the size of the property and how much of the system needs testing. If the leak turns out to be on the underground supply pipe, a repair or trenchless replacement typically runs from £1,200 to £2,800 — always confirmed as a fixed written price before we start.

    Very often, yes. Most UK home insurance policies include 'trace and access' cover, which pays for the work needed to locate a leak and to reinstate anything opened up to reach it. We provide a written report with our findings, photographs and an itemised invoice so you can submit the claim. We recommend calling your insurer before the survey to confirm your excess and the cover level on your policy.

    Not to find the leak. We use acoustic listening equipment, thermal imaging and pressure testing to pinpoint the leak to within a few centimetres before anything is disturbed. Once we know exactly where it is, the repair is targeted — a small section of floor or a single access pit rather than a whole room or driveway. For buried supply pipes we use moling, so paving, tarmac and lawns stay intact.

    Yes — we cover Horley (RH6) and the surrounding villages, including Crawley and Reigate, plus the wider Surrey area and across Sussex and Surrey from our base in Crawley Down, West Sussex.

    Yes — we handle the repair in-house, so you don't need a second trade. That covers re-soldering or replacing a failed joint, renewing a section of pipe behind a wall or under a floor, replacing perished compression fittings, and replacing an entire underground supply pipe by moling if the leak is outside. In most cases the repair is done on the same visit as the survey.
