I would like to say Jordan was a very professional, clean and tidy plumber, he also heard leaks from behind my toilet and recommended that it needs looking into which he did not have to say, I appreciate that he cleaned my sink after plumbing work and treated my property tidy after his work. he also is a friendly person to chat with and very respectful.

Pipe ownership

Whose pipe is it?

Indoors
Pipes, taps and toilets in the house are the owner's to maintain. Tenants report faults to the landlord, who arranges the repair.
Garden and drive
From your boundary to the house, the supply pipe is also the owner's. A leak under the lawn is yours to fix.
The street
Your water supplier owns the main and the pipe up to the outside stop tap. Tell them about leaks on their side.

Hard water scales up valves, so a stopcock left alone for years can jam. Turn yours now and then to keep it free.

What we see most

Common plumbing problems in Hertfordshire

Scaled-up taps

Hertfordshire's hard water leaves scale inside tap cartridges. Once they stiffen, they start to drip.

Furred shower valves

Scale also clogs shower valves and heads. Flow drops, or the temperature jumps between hot and cold.

Cisterns that keep filling

If the fill valve sticks or the flush seal wears, water runs into the pan all day and night.

Slow leaks under floors

A weeping joint under a floor can go unseen for months. Lifting boards or a damp skirting is often the first sign.

Burst pipes in winter

Pipes in lofts and garages freeze in hard weather. Close the stopcock as soon as you see water.

Leaking appliance connections

A loose fitting behind a washing machine or dishwasher leaks every cycle. The cupboard base swells before anyone spots it.

Hertfordshire plumbing questions

Do you have an emergency plumber for Hertfordshire?
Yes. Call 0800 689 3497 at any hour, including weekends. A burst pipe goes to the front of the queue.
Where is my stopcock?
Usually under the kitchen sink, where the supply comes in. In some homes it is in a hall cupboard, a garage or under the stairs.
Can you tell if I have a hidden leak?
Turn off every tap and watch the water meter. If it still moves, water is escaping somewhere. Our plumber can trace it.
Can you help with hard water damage?
Yes. We descale or replace tap cartridges, shower valves and fill valves that scale has stiffened or blocked.
What does a plumber cost in Hertfordshire?
Weekdays from 8am to 6pm, each half hour starts at £80.00 + VAT. Evening, night and weekend work is charged at other rates. We tell you which before you book.
I rent my home. Who pays for the plumber?
Usually your landlord, who must keep the water supply, basins, baths and toilets in repair. Report the fault to them or your agent first.
Can you also unblock the sink or toilet?
Yes. Our engineers handle drains as well as plumbing, so a blockage and a leak can be fixed on one visit.
Is the plumbing work guaranteed?
Yes. We stand behind our plumbing workmanship for six months, T&Cs apply. Ring if the same problem comes back in that period.
