Leak detection in Hastings.

Southern Water's supply to TN34, TN35, TN37, and TN38 runs at 270 to 310 ppm CaCO3, placing Hastings in the hard-water bracket where limescale progressively narrows bore diameter and raises operating pressure on older joints – a combination that eventually produces pin-hole failures in supply runs that can go undetected beneath Victorian flagstone floors for months.

Our leak-detection surveys open with thermal imaging across accessible floor and wall surfaces to identify anomalous temperature gradients. Where a leak signature appears beneath solid ground or road crossings, acoustic correlation equipment is deployed: paired sensors on either side of the suspected zone calculate the exact leak point to within centimetres, allowing targeted excavation rather than wholesale lifting of historic fabric. For supply mains concealed inside the listed-building stock of the Old Town or the earlier St Leonards terraces, tracer gas (a non-toxic hydrogen/nitrogen blend) is introduced to confirm pinhole positions before any work is committed.

Every survey concludes with an insurance-grade written report: test pressures, equipment calibration records, annotated site drawings, and a photographic log – formatted to the standard required by building insurers and mortgage lenders operating in East Sussex.
