Why FS Group
Our engineers cover Clapham and Brixton through Wimbledon and Sutton to Twickenham. Terraces in Battersea and Balham often have kitchen extensions built over the old drain. Larger gardens in Richmond and Twickenham bring roots into clay pipes. Relining fixes many of these without lifting a floor.
The starting rate for a standard unblock, per half hour, on weekdays 8am to 6pm. The exact rate is given on the phone first.
See all our ratesThe service from FS Drainage was second to nine. I highly recommend them. Mirren Putney
I found FS at the last minute, and they were able to find an agent to come out in a few hours which was incredible. Jordan, who attended the property, was punctual and thorough. The review of the drainage was equally thorough. I needed an honest opinion and solution to any potential issues, and that was delivered. I also felt that he was working with me, that the survey being carried out was in the interest of my future purchase of this property. I'd recommend FS to anyone who needs to review concerns from Home Buyers reports or has repairs on new purchases of any house.
Couldn’t recommend FS Group highly enough. Had an issue with my Macerator pipes being blocked. Had someone out previously who couldn’t get the job done. It was only because of this it led me to FS who had no bother sorting it, they were quick reliable and amazing to deal with. Will never use anyone else in the future!
Our toilet was blocked. We had 4 other plumbers come to fix it but no one could unblock it. JJ was great. Professional and unblocked it within an hour. Thanks so much!
FS sent their engineers the day after I called them. They knew exactly how to deal with the blocked drain at my property - and did so quickly and efficiently. I'd use FS again.
The operatives arrived on time and dealt with a horrible drain blockage very efficiently in less than an hour. They were very friendly and informative. I would definitely use again if needed.

What we see most
Kitchen extensions in Clapham and Wandsworth often sit over the original pipe. We survey it and reline it where we can, without digging.
Extra bathrooms send more water down pipes that were never sized for it. A camera shows if the drain can cope.
Buyers in Wimbledon and Putney often want a drain survey before they exchange. We record it and give you a written report.
Terraces in Clapham and Tooting often share one pipe behind the houses, so a block can affect neighbours.
Leaves and silt fill outside gullies in Streatham and Putney, so rainwater backs up towards the house.
In Brixton and Balham, cafe and restaurant grease collects in shared drains until the water stops flowing.
Call now, whatever the time. If sewage is backing up, we aim to have someone there in two hours.
