Local context

Leak detection in Crawley: what we expect on site.

Leak detection in Crawley is helped by the town's uniform stock: known pipe routes across the 1950s-to-1960s New Town estates mean we can predict where supply and heating runs go before we start tracing. South East Water's hard supply furs those runs, so the usual fault is a weeping, scaled joint rather than a burst, located with thermal imaging and acoustic correlation and confirmed with tracer gas where a run is buried. With Gatwick nearby we produce a lot of insurance-grade and landlord documentation, so every trace finishes with a written report identifying the leak and the fix. There is no callout fee; the trace is billed at our half-hour labour rate for the time of day, and any repair is quoted in writing before work starts – see /pricing.

Yes. We cover RH10, RH11 across Crawley, Three Bridges, Pound Hill, Bewbush and the rest of Crawley. Post-war New Town stock with uniform PVCu drainage installed 1950 to 1965; relining is the standard fix for the older runs.
