Leak Detection in Slough

Leak detection across Slough covers SL1, SL2 and SL3, taking in Slough town, Langley, Cippenham and Chalvey in Berkshire. Thames Water supplies a hard 270 ppm mains across the district, and the drive from the NW10 dispatch hub runs at 50 minutes. Slough is a mix of dense residential and trading-estate stock, with weekday-daytime work and PPM schedules dominating the leak-detection diary.

Trading-estate residential work brings a particular pattern: a mix of post-war 1960s and 1970s stock, original galvanised cold-feed runs in places, and modern apartment blocks with shared-riser systems around the town centre. The survey starts with a Protimeter Surveymaster and Tramex pinless moisture map to plot 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 behind plasterboard.

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 Cippenham and Chalvey 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 Langley and the trading-estate fringe, where buried MDPE service runs can be twenty-plus years old, 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. The FLIR E76 (320x240 sensor) handles routine tracing on smaller surveys. 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.
