Leak detection in Spelthorne

Chalk-aquifer supply at 280 to 320 ppm CaCO3 is the defining leak-detection factor in Spelthorne. Affinity Water's very hard water deposits scale at joint faces and on the outer wall of hairline pipe cracks, which can obscure slow weeping losses for months before moisture reaches a visible surface. On interwar properties in Shepperton and along the Sunbury reach, original copper supply lines and any pre-1970 lead connections demand precise non-invasive tracing before assumptions are made about source location.

Our surveys combine three complementary methods. Thermal imaging reveals temperature differentials behind plasterwork and under screeded floors that no visual inspection can detect. Acoustic correlation pinpoints the leak signal along pressurised supply pipes to within centimetres, eliminating guesswork about where to open up. Where a supply line runs under a concrete slab or through landscaped ground, tracer gas is introduced to find exit points with precision that acoustic methods alone cannot match. The survey concludes with a written, insurance-grade report – timestamped, mapped and referenced – suitable for submission directly to your insurer or loss adjuster. 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.
