How it works
What happens from the moment you call to the day we send the report.
We answer and listen
A member of our team answers, asks what is happening and gives you a time for the visit. For blockages, we tell you what to avoid using while you wait.
We find the cause
Your engineer lifts the covers, clears the drain if it is blocked and puts a camera through so you can both see the cause.
We give you a fixed price
If a repair is needed, you receive the footage and a fixed written price, and we tell you if any of it is the water company's responsibility.
We send the report
You receive the report, the before and after footage and the guarantee, ready for your records or your insurer.
About us
“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.

FAQs
Straight answers on price, timing and who is responsible for which drain. If your question is not here, call the office.
How much does it cost to unblock a drain?
Our blocked drain call-out is £120 including VAT and includes the first hour on site, which is enough for most blockages.
How quickly can you come out?
For blocked drains, usually within two hours. Surveys and planned repairs can normally be booked within three working days.
Who is responsible for my drains?
You are responsible for the drain that serves only your property, up to the boundary. Shared drains and lateral drains beyond the boundary have belonged to the water company since October 2011. We tell you which is which before we quote.
Are your engineers employed by you?
Yes. Everyone who comes to your property is employed by us, trained by us and carries identification.
What is guaranteed?
Patch and full-length liners are guaranteed for ten years. All other repairs are guaranteed for two years.
Will you leave a mess?
No. We put mats down around the chamber, wash down paths and drives when we finish, and take all waste away.
Do you charge VAT on top of your prices?
No. Every price on this site and in our quotes includes VAT.
Do you work for landlords and businesses?
Yes. We look after rental properties, schools and restaurants, with planned jetting and reports for each visit.
