Emergency Plumber in Letchworth Garden City
Rated 5.0 on Google · Fully insured
When a pipe bursts or water starts dripping through a ceiling, it helps to have plumbers who are already in town. Our team is based in Letchworth Garden City, and this year we have been out to Letchworth homes for leaks and burst pipes, blocked toilets and drains, taps, toilets and showers that failed, and hot water cylinders that stopped working. We're a local team rather than a call centre, and we reply to enquiries within 2 hours.

Before we arrive: four things to do
Shut the water off. The inside stopcock is usually under the kitchen sink, though some houses have it under the stairs or near the front door. Turn it clockwise until it stops. If it's seized, there is normally an outside stop tap under a small cover in the pavement or by your boundary. That one belongs to Affinity Water, the local supplier.
Keep water and electrics apart. If water is reaching a light, a socket or the fuse box, switch the power off at the consumer unit and stay clear of anything wet.
Drain what's left. Once the supply is off, open the cold taps to empty the pipes, so less water escapes from the damaged spot, and switch off the immersion heater.
Call 01462 510001. Tell us what's happening, or WhatsApp a photo to 07719 056800 so we can see it before we set off.
Urgent plumbing we deal with in Letchworth Garden City
Burst and frozen pipes
Water expands as it freezes, so a cold snap can split a pipe, and the leak often only shows once it thaws. We cut out the split section, fit new pipe and test it under pressure before anything is covered over.
Leak detection: leaks you can't find
A damp patch on a ceiling or a meter that keeps turning with every tap shut usually means a hidden leak. We trace it with pressure tests and specialist equipment, so only the area around the leak is opened up.
Blocked or overflowing toilets and drains
Stop flushing straight away. Most toilets have a small isolating valve on the pipe into the cistern: a quarter turn with a flat screwdriver stops it refilling. Drains that back up into gullies or the garden need unblocking quickly, often with high pressure jetting. More on drain unblocking.
Hot water cylinder faults
A cylinder that has stopped heating, is leaking from its base or is discharging water from a pipe outside needs looking at quickly. We repair and replace vented and unvented cylinders and immersion heaters.
Taps, toilets and showers that won't stop running
A tap that won't turn off, or a cistern that overflows into the pan nonstop, can run all night. We replace the worn cartridge, washer or valve so it shuts off properly again.
Business premises
A leak in a shop, a blocked washroom in an office or a burst pipe at a school in Letchworth Garden City is handled the same way: shut the water off, then call us. We also fit and maintain commercial washrooms and drainage, so the follow up work can be planned with the same team.
When to call us
Our lines are open 7am to 9pm Monday to Friday and 7am to 7pm on Saturday and Sunday. Call 01462 510001 and we'll give you the earliest time we can be with you. A call out fee applies to emergency visits, and we confirm it with you before we set off. Outside those hours, turn the water off at the stopcock, then send us an enquiry or a WhatsApp and we'll reply as soon as we open. Every repair we make is guaranteed for 12 months.

Why Letchworth homes get the emergencies they do
Letchworth is the world's first garden city, so the housing ranges from the original cottages of the early 1900s to post war estates such as the Grange and Jackmans, and the Lordship and Manor Park homes built from the 1970s. In homes with a cold water tank in the loft, the pipes up there run through the coldest part of the house, which is where most frozen pipes start. Lagging them, and leaving the heating on low when you go away in winter, prevents most of them.
The town's water is hard. Scale builds up on immersion heater elements, inside valves and on tap washers, which is why so many dripping taps and tired cylinders here trace back to limescale.
We cover every part of the town, including Norton, Wilbury, Westbury, Pixmore, the Grange, Jackmans, Lordship and Manor Park, plus Willian and Radwell.
