Blocked Drains in Croydon

Croydon drainage covers CR0, CR2, CR3, CR4, CR5, CR7, CR8, SE19, and SE25, taking in Croydon centre, South Croydon, Purley, Coulsdon, Thornton Heath, Norbury, Selsdon, and Addiscombe. The borough's drainage stock is dominated by 1930s 100 mm vitrified clay laterals serving suburban semis, with larger 150 mm mains under the Edwardian streets of South Croydon and Purley, and post-war PVCu in central Croydon redevelopment areas. Target arrival is 30 to 60 minutes across all nine postcodes.

SES Water supplies the bulk of the borough, and its slightly different pressure profile to Thames Water inner-London supply affects how scale builds up in waste runs. Our crews dispatch with the Harben P30 4000 PSI jetting trailer for mainline clearance, a 90 m CCTV crawler for survey work upstream of the property boundary, Sewerin acoustic location for buried lateral mapping, 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.

Coulsdon and Selsdon have longer lateral runs through larger gardens, and Croydon callouts here often start with Sewerin acoustic location before any rodding begins because the original deed plans rarely match the buried route. Thornton Heath and Norbury have heavy HMO concentrations with shared soil stacks, and a single fat blockage backs sewage into four flats at once. We work upstream of the affected unit, locate with the crawler, and clear with electromechanical rodding gear.

CIPP cured-in-place lining to BS EN ISO 11296-4 from £500 per metre (3 m minimum run) is our standard repair where excavation would damage block-paved driveways or estate access roads. Croydon's pre-1965 stock is dominated by vitrified clay; post-1965 estates around New Addington and central Croydon are PVCu, and the transition couplings between the two are recurring failure points. Air admittance valves and backflow preventers fitted as standard on basement and lower-ground installations.
