Blocked Drains in Slough

Slough drainage covers SL1, SL2, and SL3, taking in Slough town, Langley, Cippenham, and Chalvey. The district's drainage stock is mixed industrial and dense residential: Victorian 150 mm clay mains under central Slough town, 1930s 100 mm laterals across Cippenham and Chalvey, modern PVCu adoptable runs in the Langley trading estate clusters, and post-war 150 mm shared estate mains across SL2. Target arrival is around 50 minutes from the NW10 dispatch hub.

Trading estate plus dense residential profile means weekday-daytime work and PPM schedules dominate the booking pattern, and we coordinate with FM teams on the larger Slough Trading Estate addresses. Our crews dispatch with the Harben P30 4000 PSI jetting trailer for mainline clearance, a 90 m CCTV crawler with depth-logging for survey work, Sewerin acoustic location for buried laterals, electromechanical rodding gear for compacted fat, and Picote cutter heads for root intrusion at clay joints. Drain unblock priced at our flat half-hour labour rate, with no callout fee (see /pricing), CCTV survey with annotated report from £350.

Thames Water supplies the district at hard 270 ppm, and the resulting heavy scale in older copper waste runs feeding 100 mm cast-iron soil stacks across central Slough and Chalvey is the dominant blockage cause we remove with the Picote heads. Trade-waste interceptor traps and grease-trap installations across the Langley industrial cluster require regular jetting frequency to match operational throughput, and we plan PPM schedules to align with shutdown windows.

CIPP cured-in-place lining to BS EN ISO 11296-4 from £500 per metre (3 m minimum run) is our standard repair across the central Slough conservation streets where excavation would damage Victorian forecourts and stone-set pathways. We line clay sections in situ, run a post-cure CCTV survey to verify the new bore, and replace Class B manhole covers in heavy-duty industrial finish across the trading estate. Backflow preventers fitted as standard on basement gullies across SL3 lower-ground installations; air admittance valves fitted on HMO soil-stack reroutes.
