Why FS Group
Our engineers cover Norbury and Thornton Heath down to Purley, Coulsdon and New Addington. The north of the borough is mostly Victorian and Edwardian terraces. Further south, Sanderstead and Selsdon have detached houses with long private runs. Offices and restaurants in central Croydon book us for planned jetting too.
That price is per half hour, for standard weekday unblocking from 8am to 6pm. The help desk quotes your rate before anyone leaves.
See all our ratesThis operative was very thorough in making safe my leaking kitchen sink. He then came back a week later and fixed it permanently. The work was done to a high standard, he replaced taps, all pipework under the sink and sealed the lot. I am very happy with the job done and couldn't ask for any better. He was polite, cleaned up after his work and observed covid distancing. It is so good to see someone take pride in his work like this young Man. My kitchen is now leak free and my sink looks brand new.
Josh and his colleague were very helpful, friendly and professional. They quickly and efficiently found the route cause and cleared the blockage thoroughly. 10/10 service. I would definitely recommend FS Drainage Services to anyone else in the future. Many thanks again.
They were so good. Found them easily online. Responded late at night through text email and on voice mail. We’re at our home by 8.30am the next morning. Drains unblocked by 9.am super efficient and would highly recommend them to anyone with blocked drains
Fantasic service provided by William today. I had been struggling to find the blockage for a couple of days without any luck. He located the blockage and cleared it in just over an hour. I am more than happy to recommend F S Drainage to anyone. Thank you once again guys.
Got two drains unblocked on the same day for 2 houses. I was a little skeptical about using them based on pricing per 30 mins but they were professional, fast and got the job done. The team member Felix was friendly and efficient. Booking on the phone was easy. They explain well about their pricing. I’m satisfied.
Called FD Drainage at 11.58, contacted us at 12.10 to say Josh would be with us for 12.30. He arrived before 12.30, unblocked the outside drain, which was blocked with fat. Josh was friendly, efficient, tidy and professional. A credit to himself and FS Drainage. Would recommend them again. Hope you get Josh

What we see most
Blocks around East Croydon and West Croydon share drains between many flats. One misuse can block the run for everyone.
In Shirley, Selsdon and Sanderstead, older pipes and big trees mean roots in the drains.
Restaurants on the High Street and around Boxpark need grease kept out of the pipes. We jet them on a schedule.
Victorian and Edwardian terraces in Norbury and Thornton Heath often share one drain behind the row.
Leafy plots in Purley and Kenley let tree roots work into old clay joints.
Leaves and silt fill outside gullies in South Norwood and Addiscombe, so rainwater backs up.
The phones are staffed day and night. In a Croydon emergency, our aim is an engineer with you inside two hours.
