Blocked Drains in Kingston upon Thames

Kingston upon Thames drainage covers KT1, KT2, KT3, KT5, KT6, and KT9, taking in Kingston, Surbiton, New Malden, Norbiton, Berrylands, Tolworth, and Chessington. The borough's drainage stock is suburban: Edwardian 150 mm vitrified clay mains under Surbiton terraces, 1930s 100 mm laterals across New Malden and Berrylands, modern PVCu adoptable runs in the Kingston riverside apartment clusters, and post-war 150 mm shared mains around Chessington. Target arrival is 30 to 60 minutes across all six postcodes.

Larger family-house stock across KT3 and KT6 means longer lateral runs, and Kingston callouts often start with Sewerin acoustic location and the 90 m CCTV crawler before any rodding begins because the buried route rarely matches the original deed plans. Our crews dispatch with the Harben P30 4000 PSI jetting trailer for mainline clearance, electromechanical rodding gear for compacted fat and scale, 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 and SES Water both serve the borough, splitting roughly along the A3, and the moderate-to-hard supply leaves scale in older copper waste runs feeding 100 mm cast-iron soil stacks across Surbiton. Riverside apartment blocks in central Kingston have shared-riser soil stacks rising fifteen-plus storeys, and blockages at intermediate floors back into multiple flats. We work with managing agents to isolate the affected riser before clearing with rotating heads sized to the bore.

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 KT6 conservation streets where excavation would damage Edwardian front gardens and tessellated pathways. We line clay sections in situ, run a post-cure CCTV survey, and replace Class B manhole covers with period-appropriate finishes.
