Leak detection in Windsor and Maidenhead.

Affinity Water's chalk-aquifer supply arrives in Windsor and Maidenhead at 280 to 320 ppm CaCO3 – among the hardest in Berkshire – and that hardness is the dominant factor in the leak picture across SL4, SL5 and SL6. Scale builds progressively inside copper and lead supply pipes, at compression joints and around isolation valves; when a fitting finally fails, the leak is often concealed behind Victorian lathe-and-plaster walls or beneath the solid stone floors common in properties close to Windsor Castle and Eton College. Insurance-grade investigation rather than opportunistic chasing is the only reliable approach.

We deploy three complementary techniques: thermal imaging to map moisture gradients through floor and wall surfaces, acoustic correlation to pinpoint flow noise on buried mains and service pipes, and inert tracer gas injection for supply lines where acoustic signal is masked by background noise. Together they locate the source non-destructively before any opening-up work is authorised. For listed or conservation-area properties in Windsor and Eton this matters particularly, as unnecessary intervention can trigger consent issues. Every completed investigation closes with a written report documenting methodology, findings and repair scope – suitable for submission directly to your insurer. No callout fee applies; see /pricing.
