Blocked Drains in Richmond upon Thames

Richmond upon Thames drainage covers TW1, TW2, TW9, TW10, TW11, SW13, and SW14, taking in Richmond, Twickenham, Kew, Teddington, Barnes, East Sheen, Hampton, and St Margarets. The borough's drainage stock is mostly Georgian and Victorian: 150 mm clay mains under the Richmond and Kew villas, Edwardian 100 mm laterals across Barnes and Teddington, modern PVCu adoptable runs in the Twickenham riverside flats, and 1930s suburban 100 mm runs across East Sheen. Target arrival is 30 to 60 minutes across all seven postcodes.

A large amount of Grade II listed and conservation-area stock across the borough means listed-building consent often applies to visible drainage repairs, and we plan excavation to preserve York stone paving, tessellated pathways, and stuccoed boundary walls. 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 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 Affinity Water both serve the borough, splitting roughly along the river, and the moderate-to-hard supply leaves moderate scale in older copper waste runs feeding original cast-iron soil stacks across Richmond and Kew. The Thames frontage across TW9, TW10, and SW13 means we fit backflow preventers on basement gullies as standard for properties below the 5 m AOD line, particularly the listed Georgian terraces in Kew and along the Strand on the Green.

CIPP cured-in-place lining to BS EN ISO 11296-4 from £500 per metre (3 m minimum run) is the standard repair across the borough because excavating conservation-area paving and listed-building forecourts would breach the planning conditions. We line clay sections in situ, run a post-cure CCTV survey to verify the new bore, and reinstate to match the original finish. Air admittance valves fitted on internal soil-stack reroutes where listed-building consent blocks external vent terminations.
