First, We Need To Know Where The Water Is Coming From
The mistake with leaks is assuming the wet patch is where the problem started. Water travels. It can run along pipework, down the back of kitchen units, across a ceiling board, or through old boxing before it finally shows.
Some leaking pipe repairs are straightforward. A loose fitting under a sink. A worn washer. A weeping isolation valve. Fine.
Others are awkward. A copper pipe buried behind a cupboard. A heating pipe under the floor. A leak that only appears when the boiler is running. That is where experience matters, because ripping things apart too early can make the job bigger than it needs to be.
If you need broader plumbing support rather than just one leak, our main plumbers Croydon page explains the local plumbing work we cover.
Common leaking pipe callouts

What To Do Before The Plumber Arrives
If water is actively escaping, try to limit the damage first. It sounds obvious, but in a panic people start pulling at pipes, tightening random fittings, or opening cupboards while water is still running.
Look for a small isolation valve near the leak. Under sinks, toilets and appliances there is often a little valve that can be turned with a screwdriver. If that does not stop it, turn off the main stopcock.
If the leak is near electrics, do not touch anything wet. Keep away and call for help. If the leak is from a boiler, cylinder or central heating pipe, tell us that when you call because it changes what we need to check.
For urgent leaks, use our emergency plumber in Croydon service page.
Signs You May Have A Water Leak
You do not always get a dramatic burst water pipe. A lot of leaks start quietly. You might notice a musty smell, swollen skirting board, low water pressure, a damp mark, or a boiler that keeps losing pressure overnight.
| What you notice | What it could mean | What to do next |
|---|---|---|
| Dripping under the sink | A leaking trap, waste pipe, flexi hose, isolation valve or copper pipe joint. | Stop using the sink if water is escaping and call for a pipe leak repair. |
| Damp patch on a wall or ceiling | A hidden water leak from pipework above, behind tiles, or inside boxing. | Do not just repaint it. The source needs tracing. |
| Boiler pressure keeps dropping | A central heating leak, radiator valve leak, pipe leak or boiler issue. | Check visible radiators and pipework, then book a heating diagnosis if it continues. |
| Overflow pipe leaking outside | A faulty valve, cistern issue, tank problem or pressure issue. | Get it checked before it wastes water or damages brickwork. |
| Water appears suddenly and heavily | Possibly a burst pipe or failed fitting. | Turn off the stopcock and call an emergency plumber. |
If the leak is in the road, pavement or public mains pipework, it may need your water supplier rather than an internal plumber. If it is inside the property, around appliances, under sinks, near toilets, on heating pipework, or on your side of the plumbing, we can usually advise once we know what is happening.
When A Leaking Pipe Affects The Boiler
A pipe leak is not always just a plumbing problem. If the leak is on the central heating pipework, it can make the boiler lose pressure, stop radiators heating properly, or leave the system needing to be topped up again and again.
That is where plumbing and heating overlap. We can check the leak and, where needed, look at the boiler side too.
Not Every Leak Means You Need A New Boiler
Important point. A leaking pipe near a boiler does not automatically mean the boiler is finished. Sometimes the boiler is fine and the leak is from external pipework, a filling loop, a radiator valve or an old joint.
But if the system is old, badly installed, constantly losing pressure, or has several weak points, it is worth looking at the bigger picture. Especially if you are already looking at boiler installation services, a new boiler fitted, or updating old heating pipework at the same time.
We will not push replacement where repair makes more sense. If the boiler is genuinely past it, we can talk you through boiler installation in Croydon or boiler replacement without making it dramatic.
How We Approach Leaking Pipe Repairs
The first job is to work out where the leak is actually coming from. Not where the water ended up. That sounds small, but it makes a big difference.
1. Find The Source
We check visible pipework, valves, waste pipes, heating pipes and nearby fittings. If the leak is hidden, we work carefully rather than smashing into walls or floors straight away.
2. Isolate The Problem
Where possible, we isolate the affected pipe or appliance so the rest of the property is disturbed as little as possible. Sometimes the full stopcock has to be used. It depends on the setup.
3. Repair And Test
We repair or replace the failed section, test it, and check nearby joints. With older pipework, the leak you see is sometimes only the first weak point.
Local Pipe Leak Repairs Across Croydon
Croydon has a bit of everything. Flats near East Croydon station. Older terraces around Thornton Heath and Selhurst. Family houses in South Croydon. Converted properties in Norbury. Pipework can be neat and modern in one place, then a complete mixture in the next.
A common one is a slow leak under kitchen units where nobody notices until the floor starts to lift. Another is a heating pipe leak that only becomes obvious because the boiler pressure drops overnight. The customer thinks the boiler is the problem, but the water is escaping somewhere else in the system.
That is why this page is about leaking pipes, not just boilers. But when the leak is connected to the heating system, it makes sense to have someone who understands both plumbing and heating.

Aaqib MirzaLeaking Pipe FAQs
How to repair leaky pipe?
A leaky pipe repair depends on the pipe material, the location of the leak and whether the pipe is carrying mains water, waste water or central heating water. A visible leak may need a new washer, compression fitting, section of copper pipe, flexi hose, trap or isolation valve. The safest first step is to isolate the water, dry the area and get the pipe checked properly. Tape or sealant may slow a drip for a short time, but it is not a proper repair for a pressurised pipe.
Is a leaking overflow pipe dangerous?
A leaking overflow pipe is not always dangerous straight away, but it should not be ignored. It usually means a valve, toilet cistern, cold water storage tank or heating-related component is not shutting off correctly. It can waste water, stain brickwork, cause damp outside and sometimes point to a pressure or valve issue. If the overflow keeps running, book a plumber to find the cause rather than just letting it drip.
How to find a water leak?
Start with the simple checks. Look under sinks, around toilets, behind bath panels, near radiators, around the boiler, beside washing machines and anywhere pipework is visible. Check for damp smells, swollen flooring, stains, mould patches, dripping sounds and a water meter that moves when everything is turned off. If the water is hidden behind floors, ceilings or walls, the leak may need careful tracing before any repair is made.
How to find a water leak underground?
An underground water leak is harder to confirm without proper equipment. Signs include a water meter moving when all taps are off, a sudden drop in water pressure, wet patches in the garden, unusually green patches of grass, water pooling near the mains pipe route, or a higher water bill. If the leak is outside the property boundary or on the public side, your water supplier may need to deal with it. If it appears to be on your side, a plumber or leak detection specialist can advise the next step.
How to tell if you have a water leak underground?
You may have an underground leak if the ground stays wet even in dry weather, your water pressure drops, your meter keeps turning when no water is being used, or you can hear water running with all taps off. In some Croydon homes, older external pipework can also be hidden under paths, concrete or extensions, which makes the leak harder to spot. Do not dig blindly. Confirm the likely source first.
How do I know if my water is leaking?
Common signs include damp patches, dripping sounds, low water pressure, mould, musty smells, warped flooring, a boiler losing pressure, or a water bill that suddenly jumps. You can also turn off all taps and appliances, then check whether your water meter is still moving. If it is, there may be a leak somewhere on the system.
How can I tell if my water is leaking?
Look for changes rather than just obvious water. A small leak may show as a stain, a soft patch of flooring, a damp cupboard, peeling paint, or a boiler that needs topping up more than usual. If the leak is under a sink or around a toilet, you may see water directly. If it is hidden, you might only see the damage after it has been leaking for a while.
How to find a water leak in your house UK?
In a UK home, check the obvious areas first: under kitchen sinks, bathroom basins, toilets, baths, showers, radiators, boilers, airing cupboards, washing machines and dishwashers. Then check ceilings below bathrooms or tanks, skirting boards and flooring. If you cannot find the leak but the symptoms continue, call a plumber. For leaks in the road, pavement or public mains, contact your water supplier.
