Burst & Leaking Pipe Repair

A burst pipe is one of the most stressful plumbing problems a homeowner can face. Water can flood a room in minutes, damaging floors, walls and belongings, and driving up your Water Corporation bill the whole time it's running. A slow leak is quieter but no less costly, causing hidden rot and mould behind walls and under floors for months before you notice.

Our licensed Canning Vale plumbers respond fast to burst and leaking pipes across the Perth south-east. Here's what causes them, what to do in an emergency, and how we fix them.

What causes pipes to burst or leak

Pipes fail for a range of reasons, and knowing the cause helps prevent a repeat.

Age and corrosion in older galvanised steel or copper pipework, common in Perth's established suburbs.
Ground movement as WA's sandy, reactive soils shift with the seasons, stressing joints and pipe runs.
High water pressure straining fittings and joints over time.
Tree roots wrapping around and crushing underground pipes.
Physical damage from digging, reticulation work or renovations.
Poor original installation or degraded joints and seals.
Freezing, which is rare in Perth but can affect exposed pipes on the coldest winter nights.

What to do when a pipe bursts

If a pipe bursts, acting quickly limits the damage. Here's what to do:

Turn off the water at the mains. Your main stop tap is usually near the front boundary by the water meter, or where the supply enters the house. Turn it clockwise to shut it off.
Turn off the hot water system if the leak is on the hot side, to stop it drawing in water.
Switch off power to any area where water is near electrical outlets or the switchboard.
Drain the pipes by opening the lowest taps in the house to relieve pressure.
Move valuables and soak up water to protect your floors and belongings.
Call a licensed plumber.

It's worth knowing where your mains stop tap is before you ever need it. For a fuller checklist, see our guide on what to do in a plumbing emergency.

Finding the leak

Not every leak is obvious. A burst under a slab, behind a wall or underground in the garden can do serious damage before you spot a drop of water. Signs of a hidden leak include an unexplained jump in your water bill, damp patches or bubbling paint, a musty smell, reduced water pressure, or the sound of running water when everything's turned off.

Rather than cutting open walls to hunt for the source, we use specialist water leak detection equipment, including acoustic and thermal tools, to pinpoint the exact spot. That means a smaller, targeted repair and far less mess. If you suspect a hidden leak, our guide to the signs of a hidden water leak will help you spot it early.

How we repair burst and leaking pipes

Once we've located the fault, the right repair depends on the pipe and the extent of the damage.

Spot repairs

For a single burst or leaking section, we cut out the damaged part and replace it with new pipe and fittings. This is the quickest, most economical fix for an isolated failure in otherwise sound pipework.

Repiping

If your pipes are old, corroded and failing in multiple spots, patching one leak often just moves the problem down the line. In that case, replacing a run or repiping a section is the smarter long-term solution. It's a bigger job, but it puts an end to recurring leaks and the water damage that comes with them. We'll always be upfront about whether a repair or a repipe makes better sense for your home and budget.

Underground and slab repairs

Leaks under a slab or buried in the yard need careful handling. With accurate detection, we can often access and repair the exact spot with minimal disruption, and we'll restore the area properly afterwards.

Why use a licensed plumber

In Western Australia, pipe repairs must be carried out by a licensed plumber, and it's easy to see why. A poorly made joint can fail again within weeks, and mistakes on pressurised water lines cause exactly the flooding you're trying to avoid. A licensed plumber gets the repair right, uses compliant materials, and stands behind the work. It also keeps you on the right side of the rules that protect the scheme water network.

Don't wait on a leak

Even a small leak wastes water and money every single day, and a burst pipe can cause thousands in damage in a single afternoon. The sooner it's fixed, the less it costs. If you've got water where it shouldn't be, our 24/7 emergency plumbers are ready to respond.

Preventing future pipe failures

While some pipe bursts come out of nowhere, plenty can be headed off. If your home has old galvanised steel pipes, they corrode from the inside out and will eventually fail, so planning a repipe before they burst saves you the flood and the damage. Keeping your water pressure within a sensible range protects joints and fittings across the whole house, and if your pressure seems unusually high, a pressure limiting valve is a cheap fix that spares your pipes years of strain. Where tree roots are the culprit, dealing with the roots and repairing the affected line stops the same section failing again.

It's also worth knowing the age and material of your pipework, especially if you're buying an older home in suburbs like Riverton, Willetton or Gosnells. A quick inspection can flag pipes that are living on borrowed time, letting you budget for replacement on your terms rather than after a 2am burst. We're happy to assess your plumbing and give you a straight opinion on what, if anything, needs attention.

Frequently asked questions

How do I turn off the water when a pipe bursts?

Find your main stop tap, usually near the front boundary by the water meter or where the supply enters the house, and turn it clockwise to shut off the water. It pays to locate this valve before an emergency happens. Then open the lowest taps to drain the pipes and relieve pressure, and call a licensed plumber.

What causes pipes to burst in Perth homes?

Common causes include ageing corroded pipework, ground movement in WA's sandy reactive soils, high water pressure, tree roots crushing underground pipes, and physical damage from digging or reticulation work. Older galvanised and copper pipes are especially prone. Identifying the cause helps us prevent the problem coming back.

How do you find a hidden or underground leak?

We use specialist leak detection equipment, including acoustic listening devices and thermal imaging, to pinpoint the exact location of a hidden or underground leak without tearing open walls or digging up the whole yard. That means a smaller, targeted repair, less mess, and a lower overall cost to fix it.

Should I repair or repipe leaking pipes?

If it's an isolated burst in otherwise sound pipework, a spot repair is the quick, economical fix. But if your pipes are old and failing in several places, patching one leak just moves the problem along. In that case, repiping a section ends recurring leaks. We'll advise honestly on which suits your home.
