Blocked Drains in Southwark

Southwark drainage covers SE1, SE5, SE15, SE16, SE17, SE21, SE22, and SE24, taking in Borough, Bermondsey, Peckham, Camberwell, Dulwich, Walworth, Elephant & Castle, Rotherhithe, and Herne Hill. The borough's drainage stock is layered: Georgian 150 mm clay mains under the Bermondsey terraces, Victorian 100 mm laterals across Peckham and Camberwell, modern PVCu adoptable runs in the SE1 riverside cluster, and post-war 150 mm shared estate mains around Walworth. Target arrival is 30 to 60 minutes across all eight postcodes.

Elephant & Castle redevelopment has produced a heavy concentration of new high-rise stock with shared-riser soil stacks rising thirty-plus storeys and shared-riser pressure quirks, and blockages at intermediate floors back into multiple flats simultaneously. 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, and Picote cutter heads for root intrusion at Victorian clay joints. Drain unblock priced at our flat half-hour labour rate, with no callout fee (see /pricing), CCTV survey with depth-logged report from £350.

Dulwich SE21 and SE22 have substantial Edwardian housing stock with original copper waste runs feeding 100 mm cast-iron soil stacks now showing pinhole failures, and we remove tuberculation with the Picote heads rather than excavating whole sections. Thames Water moderately hard supply across the borough leaves scale in older waste runs, and the combination of scale, fat, and root intrusion at clay joints drives the bulk of our SE15 and SE5 callouts.

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 Dulwich Village and Bermondsey conservation streets where excavation would damage Georgian forecourts and tessellated pathways. We line clay sections in situ, run a post-cure CCTV survey, and replace Class B manhole covers with period-appropriate cast-iron finish. Backflow preventers fitted as standard on basement gullies across SE1 and SE16 lower-ground installations near the Thames flood-risk corridor.
