Leak Detection in Hammersmith and Fulham

Leak detection across Hammersmith and Fulham covers W6, W12, W14, SW6 and NW10, taking in Hammersmith, Fulham, Shepherd's Bush, White City, Parsons Green, Fulham Broadway, Brook Green and Wormwood Scrubs. Victorian terraces in Fulham and Brook Green, family houses around Parsons Green, ex-LCC estates in W12, and the regeneration apartments of White City all sit on a moderately hard Thames Water supply. The older copper across SW6 is now showing pinhole failures on hot-water and central-heating returns.

Fulham SW6 pinhole work is the borough's signature investigation pattern. The survey starts 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 engineered-oak and tiled floors. Pressure-decay testing across isolated sections of the primary circuit narrows the failure to a single drop or buried elbow before any board is lifted.

White City regeneration apartments bring shared-riser pressure quirks, manifold-fed bathrooms, and underfloor heating. Hydrophone work on the riser and pressure-decay tests across the flat-side stop valve confirm whether the source is inside the flat or on a shared service. The Sewerin Aquaphon A150 acoustic set (rod and ground microphone) picks up underfloor leaks on screed-and-clip systems. 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 running from the Thames Water meter to the front door, the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant) is the standard tool, with hydrogen returning to the surface through soil and paving where the leak point is. Damp surveys in basement and lower-ground flats 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.
