Blocked Drains in Bexley

Bexley drainage covers DA1 across to DA18, taking in Bexleyheath, Sidcup, Welling, Erith, Belvedere, and the Crayford and Slade Green corridors. The borough's stock is suburban 1930s semis with original 100 mm vitrified clay laterals feeding shared rear-garden manholes, plus larger post-war estates in Erith and Belvedere on 150 mm runs. Target arrival is 30 to 60 minutes for blocked drains, sewage backups, and CCTV survey work across all ten postcodes.

Thames Water hard supply leaves heavy scale in waste runs, and the combination of fat, scale, and root intrusion at clay joints drives the bulk of our Bexley callouts. We dispatch with the Harben P30 4000 PSI jetting trailer for mainline clearance, a 90 m CCTV crawler for buried-lateral mapping, and Sewerin acoustic location for the runs that no longer match the council drainage plans. Drain unblock priced at our flat half-hour labour rate, with no callout fee (see /pricing), CCTV survey with annotated report from £350, CIPP cured-in-place lining to BS EN ISO 11296-4 from £500 per metre (3 m minimum run).

Sidcup and Bexley Village have Edwardian streets with original cast-iron soil stacks still in service, and we carry the Picote cutter heads needed to remove tuberculation without damaging the bore. Erith's post-war estates have shared 150 mm laterals running between multiple terraces, and a single root mass at a clay joint can back sewage into four properties at once. We work upstream of the affected addresses, locate the obstruction with the crawler, and clear with electromechanical rodding gear before re-surveying to confirm flow.

Thames frontage at Erith and Belvedere requires backflow preventers on basement gullies, especially on properties below the 5 m AOD line. We fit air admittance valves on internal soil-stack reroutes where conservation rules limit external vent terminations, and replace Class B manhole covers where the original frames have corroded through.
