Leak Detection in Surrey Heath

Leak detection across Surrey Heath covers GU15, GU16, GU17, GU18, GU19, GU20 and GU24, taking in Camberley, Frimley, Bagshot, Lightwater and Windlesham in Surrey. Affinity Water South East and South East Water both supply the area depending on the exact postcode, and the A30 corridor is the typical approach on a 75-minute drive from the NW10 dispatch hub. Outside the M25 west, weekday-daytime bookings are the preferred pattern for leak-detection surveys.

Mixed-supply territory means the first step of the survey is to confirm which water authority serves the property, what the mains-pressure profile looks like, and whether the cold-feed runs through a stop tap inside or outside the boundary. The survey then begins with a Protimeter Surveymaster and Tramex pinless moisture map to fix the wet boundary, with the FLIR E96 thermal camera (640x480 sensor, less than 0.04 degrees C differential) following heating-circuit flow under solid floors.

Pressure-decay testing across isolated sections of the central-heating primary circuit and the cold mains narrows the failure to a single run before lifting anything. The Sewerin Aquaphon A150 acoustic kit (rod microphone on accessible valves, ground microphone on screed) covers underfloor and concrete-slab leaks across the Camberley and Frimley stock. Hydrophone work on hot-water cylinders and loft cold-water tanks confirms whether the source is a vessel or a pipework leak.

For underground supply leaks across Bagshot, Lightwater and Windlesham, where buried mains can run thirty-plus metres on detached-house plots, the 5% hydrogen / 95% nitrogen tracer gas mix (BS EN 14338 compliant) is the standard tool. Sodium fluorescein and Rhodamine WT dye under a Spectroline OPX-365 UV lamp separates above-floor plumbing from waste-pipe failures on shower trays and bath wastes. Damp surveys 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 M25-adjacent half-hour rate.
