Advanced Leak Detection Methods
Hidden leaks can cause thousands of dollars in water damage and significantly increase your water bills. Our non-invasive detection technology locates leaks behind walls, under floors and underground — without tearing anything apart.
Acoustic Listening Equipment
Highly sensitive ground microphones and contact sensors detect the sound of water escaping from pressurised pipes, even deep underground.
Thermal Imaging Cameras
Infrared cameras reveal temperature variations caused by moisture — identifying wet areas behind plaster, under tiles and in cavities.
Tracer Gas Technology
A safe, non-toxic gas is pressurised into the pipe system and detected at ground level, pinpointing leak locations with extreme accuracy.
Pressure Testing
We isolate sections of your plumbing and test pressure to confirm whether leaks exist and narrow down their location.
Leaks We Detect & Repair
From minor drips to major underground mains leaks, our equipment finds them all. Here are the most common leak types we encounter in Sydney properties.
Slab Leaks
Leaks in pipes running under concrete slabs. Common in older Sydney homes with copper pipes subject to corrosion.
Wall & Ceiling Leaks
Pipes concealed in walls and ceilings that develop pinhole leaks or joint failures over time.
Underground Water Mains
Leaks in the pipe running from the water meter to your property. Often the cause of high water bills.
Hot Water Pipe Leaks
Hot water pipes that develop leaks, often detected by warm spots on floors or unexplained heat.
Swimming Pool Leaks
Pool shell, pipe and fitting leaks detected using pressure testing and dye methods.
Comprehensive Leak Detection Solutions
Acoustic Leak Detection
Sensitive listening equipment detects the sound of water escaping from pressurised pipes — even underground or behind walls.
Thermal Imaging
Infrared cameras detect temperature differences caused by water leaks hidden behind walls, under floors and in ceilings.
Tracer Gas Detection
Non-toxic gas is injected into pipes and detected at the surface — ideal for locating leaks in complex or deep pipe systems.
Slab Leak Detection
Specialised equipment to find leaks under concrete slabs without breaking through — protecting your floors and foundations.
Residential Detection
Homes, units and apartments — we find hidden leaks that cause rising water bills and structural damage.
Commercial Detection
Large-scale leak detection for commercial properties, strata complexes and industrial facilities.
Our Process
Call & Describe the Symptoms
Tell us what you've noticed — high water bills, damp walls, mould, pooling water, or sounds of running water when nothing is on.
On-Site Assessment
Our technician arrives with acoustic, thermal and pressure testing equipment. We assess the property to determine the best detection method.
Non-Invasive Detection
Using a combination of acoustic sensors, thermal cameras and tracer gas, we pinpoint the exact location of the leak without digging or demolition.
Detailed Report
You receive a clear report with the leak location marked, photos, thermal images and our recommended repair approach.
Repair (Optional)
We can repair the leak on the spot in most cases — or provide a quote for more complex repairs if excavation or pipe relining is required.
Signs You May Have a Hidden Leak
If you notice any of these, call us for a professional inspection before the damage gets worse.
