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.
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.
Why Perth Property Owners Choose Us for Leak Detection
Non-Invasive Detection Methods
We find leaks without digging up your yard or cutting into your walls. Our acoustic, thermal, and pressure testing equipment pinpoints the exact location of a leak. This means repairs are targeted and your property stays intact.
