Water Leak Detection in Perth

A hidden leak doesn't just waste water and push your Water Corporation bill up, it quietly wrecks timber, slabs and walls long before you spot anything. Our Canning Vale crew uses acoustic gear, thermal cameras and pressure testing to find leaks without smashing anything up, then repairs the pipe on the same visit if you want.

Most leaks don't make a puddle where you can see them. The worst ones hide under concrete, sit buried in the garden or just drip away inside a wall somewhere nobody looks. Left alone they burn through hundreds of litres of scheme water, push your Water Corporation bill through the roof and rot out timber, crack foundations and grow mould long before you notice a thing.

We're licensed Canning Vale plumbers who carry professional leak detection kit, so we find hidden leaks fast and pinpoint exactly where they are without ripping your house to pieces. Here's how it actually works.

Signs you might have a hidden leak

Hidden leaks tend to give themselves away through indirect clues rather than obvious water pooling on the floor. Keep an eye out for:

• A water bill that's crept up even though you haven't changed your usage
• Running or trickling water sounds when every tap is switched off
• Damp patches, bubbling paint or stained plaster on walls and ceilings
• A persistent musty or mouldy smell you can't explain
• Warm patches on the floor, which often mean a hot water slab leak
• Water pressure that's dropped noticeably at the taps
• Cracks appearing for no reason, or a lush green patch where the rest of the lawn is dry
• Your water meter still ticking over with nothing running

Quick check: shut off every tap and appliance in the house, then stare at the water meter for a minute. If the dial keeps moving, water is getting out somewhere. Our guide to the signs of a hidden water leak covers this in a bit more detail.

How we detect leaks

Guessing and smashing through walls, that era is done. We rely on non-invasive tech to nail down a leak's exact spot, so the repair stays small and targeted rather than turning into a demolition project.

Acoustic detection

Water forcing its way out of a pressurised pipe makes a noise you can pick up, even when it's running underground or sitting beneath a concrete slab. With sensitive listening gear and ground microphones we trace that sound right to the point of escape, often within a couple of centimetres. It's scarily accurate and doesn't break anything.

Thermal imaging

A thermal camera picks up temperature differences behind walls and under floors. Hot water leaks trail warm across the image, cold water leaks leave a cooler patch, and either way we can map the path of the leak without opening a single thing up. Works especially well for leaks hiding inside wall cavities and ceilings.

Pressure testing and gas tracing

When a leak is being stubborn we can isolate individual pipe runs and pressure-test them to confirm exactly which line is the problem. Alternatively we push a safe tracer gas through the system, it escapes at the leak point and we detect it at the surface. These two methods nail the leaks that other techniques miss.

Common leaks we find

Slab leaks

Plenty of Perth homes sit on a concrete slab with water pipes running underneath. One of those pipes fails and water pools under the slab, undermines the foundations and forces its way up through the floor, not a fun discovery. Slab leaks are stubborn without proper equipment, which is exactly where acoustic and thermal detection come into their own.

Underground and service leaks

Leaks on the buried supply line between your meter and the house, or on garden and reticulation runs, can go unnoticed for months. We locate them precisely so we only need to dig one small targeted hole instead of trenching your entire yard.

Pool and spa leaks

Pool dropping faster than evaporation accounts for? A leak in the shell, plumbing or fittings will waste water and chemicals non-stop. We help track down where it's escaping so you're not constantly topping up and paying for chemicals that just disappear.

Wall and ceiling leaks

A leak inside a wall cavity or above a ceiling causes serious structural damage and mould growth before it ever shows up visibly. Thermal and acoustic tools let us find it early, before it turns into a major repair job.

Why accurate detection saves you money

Proper detection isn't just neater, it's cheaper. When we pinpoint the leak the repair is small and focused, not some costly demolition-and-guess exercise. You save on repair bills, avoid ripping up parts of your home that don't need touching and stop the ongoing water waste you're paying for every single day it runs. Fast accurate detection pays for itself, pretty straightforward.

Once we've located the leak we handle the repair too, fixing a burst or leaking pipe, resealing a joint or swapping out a failed section. And if the leak has turned into active flooding our emergency plumbers are on call around the clock.

Catching leaks early protects your home

The real cost of a hidden leak is rarely the water bill itself, although that stings when it arrives. What really hurts is the slow unseen damage to your home's bones: swollen skirting boards, lifting tiles, blistered paint and the black mould that loves a constantly damp cavity and can cause real health problems for your family. By the time a hidden leak becomes visible it's usually been running for weeks or months, so the sooner it gets found the less it costs to put right.

That's why we'd rather you call at the first hint something's off, a damp patch that shouldn't be there, a musty smell you can't explain, a water bill that doesn't make sense, than wait until the ceiling starts sagging. Detection is quick and non-destructive, and knowing for sure whether you've got a leak and exactly where it is takes the worry out of the situation either way.
