Local context

Leak detection in Woking: what we expect on site.

Very hard chalk-aquifer water at 280 to 320 ppm CaCO3 does disproportionate damage to internal supply pipework in Woking's older stock. Scale deposits force joints to work harder, pinhole corrosion initiates inside galvanised and copper runs that have never been replaced, and the result is a slow leak that often travels considerable distance along a floor screed or behind a plasterboard partition before any surface staining appears. In West Byfleet and Pyrford, where larger detached properties carry longer supply runs, the concealed loss can be substantial before a meter anomaly is noticed.

Our leak-detection surveys deploy three complementary methods: thermal imaging to map temperature differentials across floor and wall surfaces caused by water movement; acoustic correlation to pinpoint the leak position within the supply run without opening the fabric; and tracer-gas injection for hairline leaks in plastic pipework where acoustic signals are too diffuse to resolve. All three methods are non-destructive and require no excavation at survey stage. Every instruction concludes with an insurance-grade written report giving the confirmed leak location, depth estimate, photographic evidence and recommended reinstatement scope. There is no callout fee; see /pricing for fixed-price detail.

Frequently asked

Leak detection in Woking: your questions.

How fast can you reach Woking for leak detection?
60 to 90 minutes for reactive callouts via /areas/woking. We do not run reactive 24/7 callouts in Surrey unless the district is M25-adjacent (and yours is). Scheduled project visits are slot-booked from our north-west London base. Times quoted are best-effort targets, not contractual guarantees.
What does leak detection cost in Woking?
Woking leak detection survey from £449 for a 60 to 90 minute visit with written insurance-grade report (inc VAT for domestic). Any follow-on repair work charged at the hourly rate that applies at your zone and time of day, billed in 30-minute increments (see /pricing). Salt-test damp analysis from £125 per sample with 48-hour lab turnaround.
Do you cover all postcodes in Woking?
Yes. We cover GU21, GU22, GU23, GU24 across Woking, Knaphill, West Byfleet, Pyrford and the rest of Woking. Already M25-adjacent for all six reactive services. The /south-east tree links here only for the wider drainage and leak-detection project work.
What kit do you bring to Woking for leak detection?
FLIR E76 (320×240 sensor) or FLIR E96 (640×480 sensor) thermal imaging camera (sensitive to <0.04°C), Sewerin Aquaphon A150 acoustic correlator with rod and ground microphone, 5% hydrogen / 95% nitrogen tracer gas safe mix (BS EN 14338-compliant), Spectroline OPX-365 UV dye inspection lamp, and Protimeter Surveymaster moisture mapping tool.
Will the report be accepted by my insurer in Woking?
Yes. Our written leak detection reports are accepted by every major UK insurer for trace-and-access policy claims: LV, Aviva, Direct Line, Admiral, Hiscox, Zurich, AXA, RSA, NIG, Allianz, Ageas, Legal & General. Reports include location coordinates, leak rate or drainage condition estimate, photographic evidence, thermal image scans, and a recommended-repair section the customer can hand to any contractor.

Other South East services

Pair this with our other South East service.

We run both drainage and leak detection across Woking. Drainage handles the unblock + survey + relining work; leak detection handles the forensic trace + insurance report side. Many customers book both on the same visit.
