Drainage in Sevenoaks.

The Sevenoaks property stock spans several construction eras, and the drainage evidence reflects that directly. Larger Victorian and Edwardian houses in the TN13 and TN15 postcodes commonly retain original salt-glazed clayware, often running at shallow depth across gardens that have settled and shifted over a century or more. Root ingress from the mature tree cover around estates such as Knole is a documented failure mode here, with fibrous root masses capable of splitting a socket joint without any surface sign until a camera goes in. Newer estate stock in the TN16 and TN14 corridors is predominantly PVCu, where the typical failure is at offset push-fit joints displaced by ground movement.

Every survey begins with a full CCTV inspection – no assumptions, no rodding without a prior picture. Where the camera confirms a repairable defect, high-pressure water jetting clears the obstruction and a second pass verifies the result. Structural cracks or root-damaged sections are addressed by no-dig CIPP relining wherever access permits, avoiding disruption to landscaped grounds and listed curtilages. Where the damage is too severe for lining, targeted open excavation follows. There is no callout fee; pricing is fixed after survey. See /pricing.
