Leak Detection in Greenwich

Leak detection across Greenwich covers SE3, SE7, SE8, SE9, SE10, SE18 and SE28, taking in Greenwich, Blackheath, Woolwich, Eltham, Charlton, Deptford, Thamesmead and Kidbrooke. The borough's Georgian terraces in Greenwich and Blackheath sit alongside Edwardian villas across SE3 and SE9, post-war estates in Thamesmead, and modern apartments on the Greenwich Peninsula. Thames Water supplies moderately hard mains, and the older pipework across Greenwich and Blackheath conservation areas needs careful handling to preserve period finishes.

Greenwich and Blackheath conservation work begins with a Protimeter Surveymaster and Tramex pinless moisture map to fix the wet boundary, then the FLIR E96 thermal camera (640x480 sensor, less than 0.04 degrees C differential) follows heating-circuit flow under solid floors and inside chimney breasts. Pressure-decay testing across isolated sections of the central-heating primary circuit narrows the failure before any of the original floorboards or Cumberland slate is lifted.

Greenwich Peninsula new-build apartment leaks are typically about shared risers and screed underfloor heating runs. The Sewerin Aquaphon A150 acoustic kit (rod microphone on valves, ground microphone on screed) picks up underfloor leaks on screed-and-clip systems, and hydrophone work covers shared cold-water tanks where the source is on a riser rather than inside the flat. Sodium fluorescein and Rhodamine WT under a Spectroline OPX-365 UV lamp separates above-floor plumbing from waste-pipe failures on shower trays.

For underground supply leaks across Eltham and Kidbrooke, where buried mains can run twenty metres from kerb to meter, the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant) is the standard tool. Damp surveys in Thamesmead lower-floor stock close with a salt-test analysis (30 minutes on-site, 48-hour lab turnaround) for nitrate, chloride or neutral salts. Every investigation generates an insurance-grade trace-and-access report accepted by LV, Aviva, Direct Line, Admiral, Hiscox, Zurich, AXA, RSA, NIG, Allianz, Ageas and Legal & General. Survey from a fixed starting fee, repair work at the inner-London half-hour rate.
