The National Drainage Company clears blocked drains across Bexley 24/7, covering the DA and SE postcodes — Bexleyheath, Sidcup, Erith, Welling and Crayford. Pre-agreed prices, fast local response.
Bexley, in south-east London, is largely inter-war and post-war suburban housing on clay ground, with the Thames marshes along its northern edge at Erith and Thamesmead bringing genuinely low-lying, flood-prone conditions. The 1930s semis of Bexleyheath, Sidcup and Welling run on shared clay drainage now decades old and prone to root ingress, while the riverside north sees surface-water and high-water-table problems. The River Cray and River Shuttle add further low-lying pockets. Blocked shared drains, flooding near the marshes and ageing clay pipes are the everyday Bexley call-outs.
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."
