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 Three Bridges 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 Three Bridges actually involves
Housing stock and why supply pipes fail in Three Bridges
Three Bridges combines Victorian railway housing near the station with 1950s and 60s Crawley New Town estates and later development at Pound Hill and Maidenbower. The railway-era terraces are where lead is still found; the New Town properties typically have galvanised iron or early polythene that is now at the end of its life.
Ground conditions across RH10
Weald Clay dominates, with made ground close to the railway corridor. Made ground can contain buried rubble and old services, so we CAT-scan and hand-dig the first section of every pit near the line rather than assuming a clear route.
Access, driveways and reinstatement
Front gardens here are typically short, so runs are usually 8 to 15 metres and jobs are quick. Where the property fronts directly onto the pavement we keep the footway opening as small as possible and reinstate the same day.
Water supplier and postcodes we cover
Three Bridges and the surrounding West Sussex villages are supplied by Southern Water, and the properties we work on are mainly in the RH10 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 Three Bridges include Pound Hill, Maidenbower, Worth, Northgate, Tinsley Green, Hazelwick and Church Road. If you are just outside these, it is still worth calling — most of West Sussex is within our normal working radius and there is no charge for a quote.
