Leak detection in Chichester.

Portsmouth Water's chalk-aquifer supply reaches properties in Chichester, Selsey, Midhurst and Petworth at consistently very hard levels – 290 to 330 ppm CaCO3 – and that mineral profile accelerates pinhole formation in any copper pipework exposed to temperature cycling. In the conservation-area streets of Chichester city centre, where supply runs beneath stone-flagged floors and original lime-plaster walls, a slow leak can saturate fabric for months before becoming visible. Petworth Estate properties and GU28 and GU29 rural cottages served by private water supplies present additional complexity: mains-pressure monitoring is not available, so acoustic correlation and tracer gas become the primary investigative tools.

Our detection process combines thermal imaging to map temperature anomalies through floor and wall surfaces, acoustic correlation to pinpoint supply-pipe leaks by sound signature, and inert tracer gas for pipes that cannot be isolated. We can work across all construction types, including listed buildings in PO19, without destructive opening-up. Every survey closes with an insurance-grade written report: precise leak location mapped to a site plan, pressure-test results, and a recommended repair scope. There is no callout fee; the price is fixed after survey. See /pricing.
