The National Drainage Company provides drain unblocking and drainage services across Bristol, covering the BS postcodes — Bedminster, Bishopston, Easton, Redland and Clifton. Pre-agreed prices, with CCTV, jetting and no-dig repairs.
Bristol's hilly terrain and the tidal River Avon shape its drainage. Low-lying Bedminster, Southville and the city centre carry a real flood risk, while the steep Victorian terraces of Totterdown, Cliftonwood and Bishopston run on old clay drainage where gradients and root ingress cause recurring blockages. The grand Georgian housing of Clifton hides some of the city's oldest pipework, and the dense, converted terraces of Easton and Montpelier put shared soil stacks under heavy load. In Bristol, the public sewers are the responsibility of Wessex Water, and we'll tell you when a blockage sits on their network.
Older terraces run on clay pipework that tree roots find and split at the joints.
Kitchens and food businesses keep drains under constant FOG pressure.
Converted flats share soil stacks, so one wipe can back up several homes.
Older surface drains and gullies silt up and struggle in heavy rain.
"Fast, tidy and did exactly what they said. Couldn't fault them."
"Showed me the problem on camera and sorted it properly. No hard sell."
"Reliable and professional — one call and it was handled."
