Why FS Group
Blocked drains in Camden usually trace back to the age and use of the building. Georgian and Victorian terraces around Camden Town and Kentish Town run long shared pipes behind the houses. Mansion blocks send many flats into one stack. On Hampstead's hills, old trees push roots into clay joints. In Bloomsbury, colleges and hotels put heavy daily use on old drains.
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 ratesI had a very bad blocked sink waste I tried to unblock it myself over four days to no avail So I called fs who came very promptly the next day and their man rob came and solved it very quickly and gave us good advice to keep the sink block free I would highly recommend them glad I found them .
Excellent service and really helpful. Cost effective with no fuss. Will definitely recommend for any drainage issues in the future.
I cannot recommend this company highly enough. They are the most professional company and came out to clear my drains within an hour. The cost reflected the work and we are so happy.
Absolutely fast and perfect job , many thanks to Rob for everything. I recommend FS drain to anyone . Thank you !!
We have used these guys twice and both times they have been excellent. The engineers were polite and friendly and cleared our drain quickly and expertly. Very happy, a great company!
Robert the engineer showed up to my home exactly on time & cleared the foul drainage problem the previous contractor failed to do correctly. The service from FS was both professional & trustworthy from the moment I contacted them, with a polite & honest approach from Robert. Many Thanks

Who we work for
In a Gospel Oak terrace or a Hampstead family house, the camera shows you the fault before anyone digs.
Mansion blocks around West Hampstead and Kilburn often share stacks. Managing agents get the footage and a written report for their records.

What we see most
Wipes do not break down like paper. They snag at the first bend and catch everything behind them.
Old trees around Hampstead and Highgate send fine roots into clay joints. Left alone, they fill the pipe.
Being lowest on the run, a basement flat is where a blockage shows first. Water backs up there before anyone upstairs notices.
Oil and fat from kitchens along the High Street cool inside the pipe. Over time, the opening gets smaller.
Autumn leaves from street trees around Belsize Park and Primrose Hill fill yard gullies. Rainwater then sits on the surface.
Mansion blocks and converted terraces share a soil stack. A blockage high up can back up into every flat beneath it.
The help desk never closes, so ring now and we find the nearest free engineer.
