Grange PlumbingWhat 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 Redhill 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 Redhill actually involves
Housing stock and why supply pipes fail in Redhill
Redhill is dominated by Victorian terraces around the station and St John's, inter-war semis in Earlswood and Merstham, and later estates at Whitebushes. Terraced properties frequently share a single supply pipe running behind or beneath several houses — a common cause of disputes when a leak appears, because the leak may not be under the property whose bill has jumped.
Ground conditions across RH1
The area straddles the Gault Clay and Folkestone Sand boundary, with chalk to the north around Merstham. Sand moles quickly. On the chalkier northern runs we survey first and, where a bore is not sensible, use a targeted narrow excavation instead — always agreed and priced before we start.
Access, driveways and reinstatement
Where terraces share a supply, we trace and separate the pipes so each property ends up with its own dedicated MDPE main and its own internal stop tap. That removes the shared-responsibility problem permanently rather than just patching the current leak.
Water supplier and postcodes we cover
Redhill and the surrounding Surrey villages are supplied by SES Water, and the properties we work on are mainly in the RH1 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 Redhill include Merstham, Earlswood, Whitebushes, Nutfield, South Nutfield, St John's and Woodhatch. 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.
