Woking drainage and leak detection.

Affinity Water draws its supply from a chalk aquifer that produces some of the hardest water in Surrey – consistently 280 to 320 ppm CaCO3 across the GU21, GU22, GU23 and GU24 postcodes. That single fact shapes most of what we find beneath the streets and inside the walls of properties in Woking, Knaphill, West Byfleet and Pyrford.

Two services, one contractor

247 Rapid Response covers drainage and leak detection across the borough. Visits are booked project-style: one to two working days' notice, with an on-site window of 9am to 5pm. Because Woking sits within our M25-adjacent coverage zone, reactive callouts are also available locally – see /areas/woking for that service. There is no callout fee for either service; a fixed price is quoted after the survey and agreed before any work begins. Full pricing guidance is at /pricing.

Woking's property stock is a mixed picture. The town centre and Knaphill carry Victorian and inter-war terraces alongside 1970s and 1980s commuter-era detached houses, while Pyrford and the rural fringes near the RHS Wisley edge include more substantial properties with longer private drain runs. Brookwood's older residential streets add further variety. What unites them is the sustained punishment that Affinity Water's very hard chalk-aquifer supply inflicts on any fitting, pipe joint or service entry that has been in the ground for more than a decade. Scale accumulation, joint failure and slow supply-side leaks are a consistent pattern here, not an occasional anomaly. Our survey methodology is calibrated accordingly.
