Blocked Drains in Greenwich

Greenwich drainage covers SE3, SE7, SE8, SE9, SE10, SE18, and SE28, taking in Greenwich, Blackheath, Woolwich, Eltham, Charlton, Deptford, Thamesmead, and Kidbrooke. The borough's drainage stock spans four eras: Georgian 150 mm clay mains under Greenwich and Blackheath terraces, Edwardian 100 mm laterals across SE3 and SE9, post-war 150 mm shared mains across the Thamesmead estate, and modern PVCu adoptable runs at Greenwich Peninsula. Target arrival is 30 to 60 minutes across all seven postcodes.

Thamesmead's drainage is the operational anomaly: the entire estate was built below the high-tide mark on reclaimed Erith marshes, with pumped surface-water drainage and a complex network of interceptor traps and backflow preventers. We carry specialist gear for the pump-station-fed shared mains, and we dispatch with the Harben P30 4000 PSI jetting trailer, a 90 m CCTV crawler for mainline survey, Sewerin acoustic location, and electromechanical rodding gear. Drain unblock priced at our flat half-hour labour rate, with no callout fee (see /pricing), CCTV survey with report from £350.

Blackheath and Greenwich conservation areas need period-appropriate Class B covers and concealed reinstatement, and we plan excavation to preserve York stone paving and stone setts. Original cast-iron soil stacks still serve several Greenwich and Blackheath addresses, and we use Picote cutter heads to remove tuberculation without damaging the bore. Thames Water adopts public sewers upstream of the property boundary, and we map liability before quoting any upstream repair work.

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 SE3 conservation streets where excavation would breach the planning conditions. Greenwich Peninsula new-builds have shared-riser soil stacks rising above twenty storeys, and blockages at intermediate floors back into multiple flats. We work with managing agents to isolate the affected riser before deploying rotating heads sized to the PVCu bore.
