Blocked Drains in Brentwood

Brentwood drainage covers CM13, CM14, CM15, and CM4, taking in Brentwood town, Shenfield, Ingatestone, and Pilgrims Hatch. The district's drainage stock is suburban with rural fringes: 1930s 100 mm vitrified clay laterals across central Brentwood and Shenfield, Edwardian 150 mm mains under Ingatestone village, post-war 150 mm shared estate mains in pockets of Pilgrims Hatch, and private soakaway provision on the larger CM4 rural plots. Target arrival is around 60 minutes from the NW10 dispatch hub, outside the M25 east.

Shenfield Crossrail station has changed traffic patterns and approach times across the district, and we plan dispatch routes to handle the revised commuter flow. 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 across the larger plots, 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 depth-logged report from £350.

Essex & Suffolk Water (Northumbrian) supplies the district at hard 320 ppm, and the resulting heavy scale in older copper waste runs feeding 100 mm cast-iron soil stacks across central Brentwood and Shenfield drives the bulk of our callouts. Ingatestone village conservation area limits external drainage work, and we plan reinstatement to preserve the original Edwardian streetscape.

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 Ingatestone conservation streets and the Shenfield Garden Suburb where excavation would damage Edwardian front gardens and tessellated pathways. We line clay sections in situ, run a post-cure CCTV survey, and replace Class B manhole covers with period-appropriate finishes. Private soakaways across the CM4 rural fringe silt up after thirty years of service; trial holes and percolation tests precede any rebuild work.
