Grovebrook Drainage is a team of five based in Bovingdon, near Hemel Hempstead. We have been clearing, surveying and repairing drains across west Hertfordshire since 2016.
Everyone who works at your property is employed by us. We do not use subcontractors, and we do not quote for a repair until you have seen the camera footage.

“We show you the camera footage before we quote, so you can see the problem for yourself.”
Simon spent nine years with a regional drainage contractor, working on everything from blocked gullies to adopted sewer repairs, before starting Grovebrook from a yard in Bovingdon in 2016.
He still carries out many of the CCTV surveys himself and writes every survey report. The business is named after the small stream that runs behind our yard and into the Bulbourne.
