Why FS Group
Our engineers cover Wealdstone and South Harrow out to Pinner, Stanmore and Kenton. Pairs of 1930s semis often share a drain, which changes who pays for the work. Mature gardens in Pinner and Hatch End bring roots into the pipes. We show you on camera exactly where your problem sits.
Weekdays from 8am to 6pm, a standard unblock is charged per half hour. Ring first and you learn the rate before an engineer leaves.
See all our ratesFS Drainage are very professional at their job. I had a leak in the ceiling space that British Gas couldn’t fix but They fixed it it under 2 hours even though it was a week leading to Christmas when Plumbers were scarce. Very good Service and cleaned up as well. I will use them again and I recommend them
Mitch was so nice and did washed the place throughly, after sorting out blocked drains. He went above and beyond to fix the problem. Thank you Mitch.
FS Drainage came out the same day, after an initial email enquiry in the morning. Uchenna was polite and professional and managed to clear our exterior blockage in no time at all. Excellent service, highly recommended :)
We had to unblock our drain. Such a professional service. They came out on short notice and were incredibly polite and respectful. Maintained communication throughout any delays. Everything was transparent and clear from the start. The engineer (James) also gave us plenty of information on how to look after the drain for the future. Will most definitely be using this service again!
I would highly recommend FS Drainage Services. From start to finish their communication was excellent. Dominic took time to explain everything clearly before I booked and the pricing was transparent. Josh called before his visit, he was professional and friendly, explained everything again in detail, completed the job efficiently and left the premises clean. I will definitely be using their services again. Thank you
Mitch from FS Drains attended my property to sort the drainage blockage issue outside my house. He was professional and friendly and fixed the issue quickly. I am happy with his service and would recommend him for any drainage related problems. Thanks, Rah

Drain ownership
Much of Harrow was built in the 1920s and 1930s, and many homes still sit on the clay drains from that time.
Who we work for
In a Pinner semi or a Wealdstone terrace, the cost per half hour is clear before anyone drives over.
Flats in town centre conversions share soil stacks. Camera surveys come with the recording plus a written report.

What we see most
Tree-lined roads in Pinner and Stanmore bring roots into old joints. We cut them out, then reline the pipe so they stay out.
Many Harrow semis have grown, with extra bathrooms on old pipes. We check whether the drain can carry the load.
Suburban roads here often have one pipe for waste and another for rainwater. A wrong connection can send sewage into the wrong one.
Kitchens on Station Road and in Wealdstone pour away fat that cools in the drain and narrows it.
Leafy streets in Pinner and Hatch End fill yard gullies each autumn, so rainwater backs up.
Converted houses and new flats in Harrow town centre share soil stacks, so a block affects the flats below.
Ring us any time. A drain emergency in Harrow is met with our two-hour response.
