Need Urgent Plumbing Help?
If the problem is active, spreading or affecting your ability to use water safely, it is better to get advice quickly. Some plumbing issues can cause damage if they are left for too long, especially when water is leaking into floors, walls, ceilings or cabinets.
Call us if you are dealing with:
- A sudden leak
- A burst pipe
- Water coming through a ceiling
- An overflowing toilet
- A blocked toilet that cannot be used
- Water around pipework or fixtures
- A serious tap, toilet or fixture fault
- A sudden loss of water pressure
- Plumbing problems affecting your bathroom or kitchen
- A fault that could cause water damage
What to Do Before We Arrive
If you have an active leak or urgent plumbing problem, a few simple steps may help reduce further damage before the issue is inspected.
If it is safe, you can:
- Turn off the main stopcock
- Turn off the local isolation valve if you know where it is
- Move items away from the affected area
- Place towels or a container under minor drips
- Avoid using affected fixtures
- Avoid repeated flushing if the toilet is blocked or overflowing
- Keep children and pets away from wet areas
- Take photos or a short video of the issue
- Tell us whether the water is hot, cold, clean or wastewater
Do not attempt repairs if you are unsure, if water is near electrics or if the situation feels unsafe.
Call Fix Your HouseBurst Pipe in North West London
A burst pipe is the one plumbing fault where the first minute changes the size of the bill. Everything below assumes water is coming out now.
The First Sixty Seconds
- Turn the water off at the internal stopcock. Clockwise, until it stops.
- Open the cold taps, kitchen first, to drain the pipework down. Less water in the system means less water on the floor.
- If water is anywhere near lights, sockets or the consumer unit, do not touch them. Switch the power off at the consumer unit only if the unit itself is dry and you can reach it safely.
- Get a container under the drip and move what you can. Lift anything soft off the floor.
- Take a photo or a short video. It helps us understand the fault before we arrive, and it helps you afterwards.
- Call 07777 759333. The phone is answered 24 hours a day.
Where the Stopcock Usually Is in a North West London Property
If you have never found yours, look now rather than while a ceiling is coming down.
- Under the kitchen sink, at the back of the cupboard behind the waste trap. This is the most common position by a wide margin.
- 1930s semis around Mill Hill, Edgware, Burnt Oak and Hendon: usually under the kitchen sink, sometimes in a downstairs cloakroom or utility, occasionally in an attached garage.
- Victorian and Edwardian terraces in Finchley, Hendon and Golders Green: often under the hallway floorboards near the front door, under a hatch or a loose board, or in a cellar where there is one.
- Flats, converted and purpose-built: commonly in an airing cupboard, under the bath, or behind a kitchen kickboard. In a conversion the valve for your flat may sit in a shared hallway cupboard.
- The external stop tap is under a small metal or plastic cover in the pavement or front path, at the bottom of a narrow chamber. It needs a stopcock key. A screwdriver will not reach it.
If the internal stopcock turns but the water keeps running, the leak is upstream of it or the pipe is fed from a storage tank in the loft. Either way it needs someone out.
What Not to Do
- Do not tape the pipe and leave it. A wrapped joint under pressure fails again, usually overnight.
- Do not force a stopcock that will not move. Old brass ones seize and shear, and a sheared stopcock turns a burst pipe into a much bigger job.
- Do not go into a loft or under floorboards where water is running near cabling.
- Do not push or pierce a bulging ceiling to release the water. It can come down in one piece.
- Do not run the heating while the system is drained down.
When It Needs Someone Out
Call rather than wait if any of these apply:
- Water is coming through a ceiling or a light fitting.
- You cannot find the stopcock, or it will not turn.
- Water is still flowing after the stopcock is off.
- It is wastewater rather than clean water.
- The leak is behind plaster, under a floor or inside a wall and you cannot see the source.
- The property is empty or tenanted, or you are away from it.
We carry out emergency plumbing work across North West London, and in our core areas we can typically be with you within the hour. If the source is not obvious once the water is off, we can trace it — see leak detection and leak repair.

Emergency Plumber FAQs
What should I do if a pipe bursts?
If it is safe, turn off the main water supply at the stopcock and move items away from the affected area. Avoid using nearby fixtures and call for plumbing help.
What should I do if water is coming through the ceiling?
If safe, turn off the water supply and avoid using rooms or fixtures above the affected area. Keep away from electrics and call for urgent plumbing advice.
Is a blocked toilet an emergency?
A blocked toilet can be urgent if it is the only toilet in the property, if it is overflowing or if wastewater is backing up.
Can you help if I am not sure what is causing the problem?
Yes. Contact us with a description of the issue and photos where possible. We can advise whether it sounds like an emergency plumbing fault, leak, blockage or another issue.

How quickly can you get to me?
The phone is answered 24 hours a day, and in our core areas we can typically be with you within the hour. Those core areas are Mill Hill, Edgware, Hendon, Finchley, Golders Green, Colindale, Burnt Oak, Stanmore and Barnet. Further out, or over the Hertfordshire border in Borehamwood and Elstree, it depends on traffic and on what we are already working on. The honest version is that this is a target we meet most of the time in the core patch rather than a guarantee for every job at every hour, and if we cannot reach you quickly we would rather say so when you call than leave you waiting. While you wait, turning the water off at the stopcock will do more to limit the damage than anything else.
I have turned the stopcock off but water is still coming through. Why?
Almost certainly because the water is coming from a storage tank rather than the mains. A lot of North West London housing still runs on a gravity-fed system: a cold water tank in the loft feeding a hot water cylinder in the airing cupboard. The stopcock only shuts off the mains supply entering the property, so the tank carries on emptying through the leak, and a loft tank holds a serious volume of water. What to do is close the gate valves on the pipes leaving the loft tank and the cylinder as well, then open all the cold taps downstairs so the tank drains down through the taps quickly and deliberately instead of slowly through your ceiling. If the water is hot, switch off the immersion heater or the boiler too, so the cylinder is not being reheated while it empties. In a newer flat or a property on a combi boiler there is no tank at all, so if closing the stopcock does not stop the flow, the source is probably not your property, and you should check whether a flat above you is leaking.
Does an emergency call-out cost more at night or at the weekend?
We do not publish a fixed emergency rate, and we would rather you asked on the call than guessed from a web page. What we can set out plainly is what changes the figure: the time of day, how long the job takes, whether the fault can be made safe and left until normal hours or has to be finished on the spot, and whether parts are needed at short notice. Ask for the number when you phone, before anyone sets off. It is a fair question and it should not be an awkward one.
Water is coming into my flat from the flat above. What can I do?
Work on your own side of the boundary first, because the leak itself cannot be stopped from your ceiling. Turn off your own water at the stopcock if water is anywhere near your electrics, switch off the affected circuits at the consumer unit, move what you can, and photograph everything before you clear up. Then get access agreed with the flat above. In a converted North West London terrace or a purpose-built block, the source is usually a bath seal, a shower tray, a waste connection or a failed flexible tap connector, and it is often offset from where your stain appears rather than directly above it, because water travels along a joist before it drops. If nobody is home upstairs, contact the managing agent or freeholder rather than opening the ceiling yourself. We can attend your side, make it safe and help trace the likely source, but we cannot enter another property without the occupier's permission.
Is a boiler breakdown or a loss of heating something you can attend?
We can attend leaks and water-side faults on a heating system at any hour: leaking radiator valves, leaking pipework, a leaking towel rail, a corroded radiator. We are not Gas Safe registered and we do not carry out gas work, so a boiler fault, a gas supply problem or anything inside the boiler casing has to go to a Gas Safe registered engineer, and we will tell you that on the phone rather than send someone who cannot legally do the work. If you can smell gas, do not wait: leave the property, do not touch light switches, and call the National Gas Emergency Service on 0800 111 999.
