Blocked Drains in Wandsworth

Wandsworth drainage covers SW8, SW11, SW12, SW15, SW17, and SW18, taking in Battersea, Clapham Junction, Putney, Tooting, Balham, Wandsworth Town, Earlsfield, and Nine Elms. The borough's drainage stock is layered: Victorian 150 mm clay mains under the Battersea and Tooting terraces, modern PVCu adoptable runs in the Nine Elms and Battersea Power Station cluster, 1930s 100 mm laterals across Putney, and post-war 150 mm shared mains across Earlsfield. Target arrival is 30 to 60 minutes across all six postcodes.

Nine Elms and Battersea Power Station have strict managing-agent access protocols for any drainage intervention, and the shared-riser soil stacks rising forty-plus storeys produce shared-riser pressure quirks that affect drainage flow at intermediate floors. 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.

Conversions in SW17 and SW18 often hide pitch-fibre drainage that has deformed under load and is now an active failure point, and we identify pitch-fibre routes with the CCTV crawler before quoting any repair or lining work. Thames Water softer-than-north-London supply still leaves moderate scale in older copper waste runs feeding 100 mm cast-iron soil stacks across Battersea and Tooting.

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 SW11 and SW15 conservation streets where excavation would damage Victorian forecourts and tessellated pathways. We line clay and deformed pitch-fibre 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 SW8 and SW11 lower-ground installations near the Thames flood-risk corridor.
