Why FS Group
Our engineers cover Hertfordshire, from Watford and Borehamwood to St Albans, Hertford and Stevenage. Welwyn Garden City was laid out from 1920, and Stevenage was Britain's first post-war new town. Their estates were planned in one go, so many homes share drain runs with neighbours. Older market towns such as Hitchin and Ware still have plenty of clay pipes. A camera survey shows what is under your home.
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 ratesA small but complex blockage was expertly cleared by Josh. Much appreciated and will most definitely use again. Thank you Josh.
Great service. I have issues with my drainage for a while. Jordan was so friendly, very professional, managed to get all sorted for me.
Jordan provided an excellent unblocking and descaling service. He explained the problems well and showed that he was enthusiastic about his work and the great results he achieved. And I was able to get appointments very quickly, within the day. An excellent all round service.
Mitch came to sort out my drainage issue and cleaning. He was extremely professional and polite. He did an amazing job and I would recommend him to anyone. He was also very caring and made us feel comfortable whilst carrying out the work.
Excellent service - Rob, the drainage engineer was first rate. He came at the planned time, did a thorough job in clearing the sewer, gaing entry via two neighbours' inspection chambers.
Very professional service. The tradesman, James, explained everything well before the work. There was no unexpected surprise. After resolving the blockages, he kindly made the area clean and tidy. I am very happy with them would recommend others.

Drain ownership
AL, EN, HP, SG and WD postcodesHertfordshire mixes planned towns with old market towns and villages, so its drains vary widely in age and layout.
Who we work for
In a Watford terrace or a Harpenden family home, the engineer explains what is wrong before starting.
Flats in St Albans and Hemel Hempstead often share one soil stack. Every survey comes with the footage and a written report.

How it works
0800 689 3497 is answered day and night. Or leave your details and we call you back within 15 minutes.
We give you the half-hour rate before an engineer drives to Watford, Stevenage or wherever you are.
The engineer clears or mends the drain, and the work is guaranteed for six months, T&Cs apply.
What we see most
So-called flushable wipes hold together in the pipe. They catch at the first bend and the toilet stops draining.
Clay soils in parts of Hertfordshire shrink in dry spells and swell after rain, pulling old pipe joints apart.
In Stevenage and Welwyn Garden City, many homes share drain runs, so one blockage can affect several houses.
Takeaways in Watford and St Albans wash fat into the drain. It sets hard and slows the flow.
Tree-lined roads in Harpenden and Berkhamsted drop leaves into yard gullies each autumn, and rainwater backs up.
Converted houses and new flats in Watford and St Albans share soil stacks, so one blockage reaches the flats below.
Phone day or night and we send the nearest engineer who is free.
