Leak Detection in Tower Hamlets

Leak detection across Tower Hamlets covers E1, E2, E3 and E14, taking in Whitechapel, Bethnal Green, Bow, Canary Wharf, Wapping, Limehouse, Stepney, Isle of Dogs and Shoreditch. Georgian terraces in Spitalfields, post-war council towers across E1 and E3, dockside warehouse conversions in E14 and Wapping, and Canary Wharf high-rises all draw on a moderately hard Thames Water supply, with pressure-stepping required in the high-rise stock and specialist booster-pump setups across E14.

Canary Wharf and Wapping high-rise work brings the most specialist brief in the borough: shared-riser systems with pressure-reducing valves on every floor, booster-pump arrangements in plant rooms, and managed-building access protocols. The survey starts with pressure-decay testing across isolated sections of the flat's plumbing to confirm whether the source is inside the unit or on a shared service. Hydrophone work on plant-room cold-water tanks rules vessel-side sources in or out before any opening up.

The Sewerin Aquaphon A150 acoustic kit (rod microphone on valves, ground microphone on screed) finds underfloor leaks on screed-and-clip systems across the high-rise stock. The FLIR E96 thermal camera (640x480 sensor, less than 0.04 degrees C differential) reads heating-circuit flow through finished floors and across plasterboard ceiling voids. Sodium fluorescein and Rhodamine WT under a Spectroline OPX-365 UV lamp separates above-floor plumbing from waste-pipe failures on shower trays and bath wastes.

Spitalfields Georgian-terrace and Bethnal Green Victorian-terrace work uses a Protimeter Surveymaster and Tramex pinless moisture map plus the FLIR E76 (320x240 sensor) for routine heating-flow tracing. Underground supply leaks across the Isle of Dogs estates use the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant). Damp surveys close with a salt-test analysis (30 minutes on-site, 48-hour lab turnaround). 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.
