Why FS Group
Our plumbers cover Hertfordshire from Rickmansworth and Hemel Hempstead to Hitchin, Hertford and Bishop's Stortford. Hard water is the daily enemy here, scaling up taps, valves and shower heads. We also fix the leaks and running toilets every house gets in time. When a pipe bursts, the help desk sends someone out at any hour.
This is the weekday half-hour rate between 8am and 6pm. Other times cost more, and you hear the rate before you agree.

Pipe ownership

About Priority AccountsHow it works
Someone picks up 0800 689 3497 day and night. Tell us what is leaking, dripping or not working.
We confirm the half-hour rate on the call, before a plumber heads for Watford, Hitchin or your door.
Once the repair is done, the plumber tests it under pressure. Our work is guaranteed for six months, T&Cs apply.




What we see most
Hertfordshire's hard water leaves scale inside tap cartridges. Once they stiffen, they start to drip.
Scale also clogs shower valves and heads. Flow drops, or the temperature jumps between hot and cold.
If the fill valve sticks or the flush seal wears, water runs into the pan all day and night.
A weeping joint under a floor can go unseen for months. Lifting boards or a damp skirting is often the first sign.
Pipes in lofts and garages freeze in hard weather. Close the stopcock as soon as you see water.
A loose fitting behind a washing machine or dishwasher leaks every cycle. The cupboard base swells before anyone spots it.
Call whenever the water starts. The help desk books the nearest free plumber.
