Leak Detection Methods & Services

We use advanced, non-invasive technology to locate water leaks accurately, whether they’re hidden underground, inside walls, or beneath concrete slabs.

Acoustic Leak Detection

We use advanced sound technology to detect the noise of water escaping from pipes under pressure. Acoustic detection is especially effective for locating leaks hidden underground or within walls where they are not visible, without any digging required.

Thermal Imaging

Using advanced infrared cameras, we capture temperature variations to visualise areas where leaks are causing changes in the thermal profile of your building. This method is particularly effective for detecting hidden moisture in walls, ceilings, and floors that hasn’t yet shown visible signs.

Pressure Testing

We apply pressurised air or water to your pipes and monitor for any pressure drop, which indicates the presence of a leak or burst pipe. Pressure testing is a definitive method for verifying pipeline integrity, suitable for both new installations and existing systems.

Underground Leak Detection

Underground water leaks are among the hardest to find and the most damaging if left unchecked. Using a combination of acoustic listening equipment and pressure testing, we pinpoint underground pipe leaks accurately, saving you from unnecessary excavation and property damage.

Slab Leak Detection

Leaks beneath concrete slabs can go undetected for months, causing foundation movement, cracking, and water damage. Our non-invasive slab leak detection methods locate the exact source without breaking through your flooring, common in Perth homes built on sand and clay soils.

Emergency Leak Repair

A burst pipe or major water leak can cause thousands of dollars in damage within hours. We provide 24/7 emergency leak detection and repair across the Perth metro area, arriving fast to locate the source, stop the flow, and carry out repairs on the spot.

Don’t Ignore a Leak. It Only Gets Worse.

Even a small leak can cause moisture build-up behind walls and under floors, leading to mould, structural damage, and rising water bills. Get it found and fixed before it becomes an emergency.

Common Causes

What Causes Water Leaks in Perth Properties?

Understanding what causes leaks helps you spot the warning signs early. Here are the most common reasons Perth plumbers are called out for water leak detection.

Burst Pipes

The most obvious cause of a water leak and the most urgent. A burst pipe can flood your home or business in minutes and requires immediate emergency response to prevent serious structural damage.

Corrosion & Ageing Pipes

Perth’s water quality and mineral content accelerate corrosion in older copper and galvanised steel pipes. Over time, pipe walls thin and develop pinhole leaks that are difficult to detect without specialist equipment.

Tree Root Intrusion

Tree roots naturally seek out moisture and can penetrate pipe joints and small cracks in underground plumbing. This is one of the most common causes of hidden underground leaks in Perth’s established suburbs with mature trees.

Ground Movement & Slab Shift

Perth’s sandy and reactive clay soils expand and contract with moisture changes, causing ground movement that shifts and stresses underground pipes. This can crack joints and fittings, leading to slow slab leaks that go unnoticed for months.

Worn Seals & Faulty Fixtures

The seals, washers, and connections that keep your plumbing watertight wear out over time. What starts as a small drip from a tap, toilet cistern, or pipe fitting can worsen significantly if not detected and repaired early.

Poor Previous Plumbing Work

Incorrectly installed or poorly maintained plumbing is far more likely to develop leaks. Substandard joins, wrong pipe sizing, and skipped pressure testing during installation can all cause problems years down the track.

Common Questions

Frequently Asked Questions About Leak Detection in Perth

Got questions about water leak detection in Perth? Here are the answers our residential and commercial clients ask most often.

No, our leak detection methods are specifically designed to be non-invasive. We use acoustic listening equipment, thermal imaging cameras, and pressure testing to locate leaks without digging, cutting, or damaging your property. In most cases, we can pinpoint the exact leak location before any physical work is required, keeping disruption to an absolute minimum.

The duration depends on the property size and the complexity of the plumbing system. A standard residential property typically takes one to two hours to inspect thoroughly. Larger commercial properties or properties with complex pipe networks may take longer. We’ll give you an estimated timeframe when you book.

Leak detection costs vary based on the scope of the inspection and the methods required. We offer a $0 call-out fee during business hours* and provide a fixed-price quote before any repair work begins. Detecting and repairing leaks early almost always saves you money in the long run by preventing water waste, structural damage, and more extensive plumbing repairs.

Yes. We use non-invasive methods including acoustic detection, thermal imaging, and pressure testing to find leaks without any digging. Our specialist equipment allows us to pinpoint underground leaks, slab leaks, and leaks within walls by detecting sound, temperature changes, and pressure drops — so we know exactly where to look before any excavation is considered.

Contact us immediately — the longer a leak goes undetected, the more damage it causes and the more expensive the repair. Before calling, note any signs you’ve observed: the sound of running water when all taps are off, damp patches, a sudden spike in your water bill, or warm spots on the floor. This information helps us identify the likely cause and bring the right equipment. For burst pipes, call us on (08) 6185 3008 for 24/7 emergency response.

We recommend an annual plumbing inspection for most residential properties, particularly older homes with ageing pipe systems. Commercial properties and high-risk buildings such as aged care facilities and hospitality venues may benefit from inspections every six months. Regular checks catch small leaks before they become expensive emergencies.

This depends on your specific policy and the cause of the leak. Many home and commercial insurance policies cover sudden and accidental water damage, but not gradual leaks caused by wear and tear. Having a professional leak detection report can support your insurance claim by documenting exactly where and when the leak was identified. We recommend checking with your insurance provider to understand your coverage.
