Drainage in Lewes.

Newhaven's tidal and flood-plain context means that drainage work in BN9 and BN10 is never routine, and we treat every blocked or slow-running run in those postcodes as a potential backflow risk until the CCTV footage proves otherwise. Our process begins with a push-rod or crawler camera survey that records every joint, root intrusion and deformation to a timestamped video file; we then cross-reference flow direction against the known flood-risk envelope before recommending a fix.

Where jetting will clear the blockage and restore adequate flow, we jet. Where the pipe fabric is deteriorated – common in the Victorian-era clay runs that still serve many of the conservation-area cottages in central Lewes – we present a no-dig CIPP relining option that avoids opening listed curtilage. Hard chalk-formation ground beneath much of the district makes full excavation expensive but straightforward where relining is not viable.

At Peacehaven and Seaford (BN10, BN25) we additionally check whether any anti-backflow provisions are in place at the outfall. There is no callout fee; the price is fixed after survey. See /pricing.
