Blocked drains in terraced streets
We clear blocked drains in terraces and flats with high-pressure jetting and help you work out whether the problem is in your drain or a shared one.

Chatham is at the heart of the Medway Towns, with Rochester, Gillingham and Strood alongside. Long streets of Victorian terraces climb the hills above the river, there are busy high streets and takeaways, and industrial estates around the old dockyard and beyond. It’s all on mains drainage, so our work here is drains, grease traps and interceptors.
Terraced houses often share drains that run behind or beneath them, and many have been split into flats. Steep streets and tight parking make access part of the job. On the Hoo Peninsula to the north, villages such as High Halstow, Cliffe, Cooling and Allhallows have homes, farms and holiday parks with private drainage.
Our crews work in Kent most days and we answer the phone 24 hours a day, 365 days a year.
