Drainage in Tandridge.

Tandridge's varied property stock generates an equally varied drainage caseload. Around Caterham and Warlingham, the older Victorian and Edwardian terraces commonly retain original vitrified clay lateral runs with push-fit or mortar joints that have shifted over the decades on the chalk and greensand substrates of the North Downs edge – root intrusion from mature garden trees is a consistent finding in the CR3 and CR6 postcodes. Further south into RH7, RH8 and RH9, interwar and postwar stock often mixes short runs of legacy cast iron with later PVCu, producing joint mismatches that show up under CCTV survey even when the surface gives no visible sign of trouble.

Every investigation begins with a full push-rod or crawler CCTV survey to locate deformation, root ingress, settled joints or fracture before any intervention is decided. Where blockage or partial collapse is confirmed, high-pressure water jetting clears the line and a follow-up camera pass verifies the result. Where the pipe wall is compromised but excavation is not warranted, no-dig CIPP relining reinstates structural integrity without open trenching. Only where collapse or severe offset is found does full excavation follow. There is no callout fee; pricing is fixed after survey. See /pricing.
