Blocked drain Croydon

Why drains block in Croydon

Croydon has a lot of Victorian terraces in Thornton Heath, South Norwood and Addiscombe, many with their original clay drains. Converted flats share soil stacks, so one blockage can affect several homes, and the southern suburbs sit on chalk and clay that move with the seasons.

Shared soil stacks

Converted flats in central Croydon and Thornton Heath share one stack, so a blockage backs up into several homes.

Victorian clay drains

Old pipework in South Norwood and Addiscombe cracks and holds waste, so blockages come back.

Ground movement

Chalk and clay in the southern suburbs move in dry summers and can displace drain joints.

Recent local jobs

Drains we have cleared in Croydon

Thornton Heath, CR7 · September 2026

Blocked outside gully

The back gully kept overflowing, particularly when the washing machine was running. We jetted the drain to clear a build-up of fat and silt, then checked the flow with plenty of water.

South Croydon, CR2 · June 2026

Blocked drain at a shared property

Two flats were having problems with slow drainage, and water had started collecting around the outside inspection chamber. We found a blockage further along the shared pipe, cleared it with jetting and checked the affected outlets afterwards.
