Leak Detection in Woking

Leak detection across Woking covers GU21, GU22, GU23 and GU24, taking in Woking town, Knaphill, Brookwood, Mayford and Pyrford in Surrey. Affinity Water South East supplies a hard 280 ppm mains across the district, and M25 J11 is the natural approach on a 70-minute drive from the NW10 dispatch hub. The district sits outside the M25 west, so booking lead-time helps with peak-hour travel and survey arrival windows are scheduled accordingly.

Woking town-centre new-build apartment work brings shared-riser pressure quirks, screed-and-clip underfloor heating, manifold-fed bathrooms, and managing-agent access protocols. The survey starts with pressure-decay testing across isolated sections of the flat's plumbing to confirm a flat-side leak versus a riser issue, then hydrophone work on shared cold-water tanks rules vessel-side sources in or out. The Sewerin Aquaphon A150 acoustic kit (rod microphone on valves, ground microphone on screed) finds underfloor leaks on screed-and-clip systems.

Family-house work in Pyrford and Mayford uses a Protimeter Surveymaster and Tramex pinless moisture map first, then the FLIR E96 thermal camera (640x480 sensor, less than 0.04 degrees C differential) follows heating-circuit flow under solid floors and inside boxed-in cylinder housings. Pressure-decay testing on the primary circuit narrows the failure to a single radiator drop or buried elbow before any board is lifted.

For underground supply leaks across Knaphill and Brookwood, where front-garden runs can stretch thirty metres or more, the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant) is the standard tool. Sodium fluorescein and Rhodamine WT under a Spectroline OPX-365 UV lamp separates above-floor plumbing from waste-pipe failures on shower trays. Damp surveys close with a salt-test analysis (30 minutes on-site, 48-hour lab turnaround) for nitrate (rising), chloride (penetrating) or neutral (plumbing) 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 M25-adjacent half-hour rate.
