Leaks buried under your garden, driveway, or concrete foundation are impossible to see. We use specialised equipment to locate these leaks with minimal disturbance, saving you from costly excavation.
Bathroom & Shower Leaks
Leaks in wet areas often go unnoticed until significant damage is done. We pinpoint hidden leaks behind tiles and cabinets from failed waterproofing or faulty pipes, crucial for any renovation.
Roof & Balcony Leaks
Water ingress from worn tiles, damaged flashing, or failed membranes can damage ceilings and walls. We accurately diagnose the source of the leak to prevent costly interior damage.

A leaking pool wastes thousands of litres of water. Our experts precisely locate leaks in your pool’s structure or plumbing, so you can stop the water loss and get back to enjoying your pool.
Internal Wall & Ceiling Leaks
We locate the source of moisture behind drywall and in ceiling cavities within multi-story buildings, preventing the spread of water damage and mould between floors.

Common questions about leak detection.
Can your service find leaks under concrete slabs?
Yes, absolutely. We specialize in locating under-slab leaks using non-invasive methods like acoustic listening devices and tracer gas detection, which allows us to find the source without cutting or drilling your concrete floor.
How long does a leak detection process typically take?
The duration depends on the complexity of the leak. A simple, obvious leak may be found in an hour or two, while more complex hidden leaks could take longer. Our goal is always to work as efficiently as possible to provide a definitive answer.
Is the detection process disruptive to my home?
No, our methods are designed to be non-invasive and non-destructive. We use technology that allows us to find leaks without needing to make holes in walls or dig up your property. The process is clean and quiet.
How much does leak detection cost in Sydney?
The cost depends on the leak's location and the techniques required. However, investing in professional detection is far cheaper than paying for extensive water damage repairs or needlessly excavating the wrong area.
Why not just call my regular plumber to find the leak?
While plumbers are great at repairs, most aren't equipped with the specialised diagnostic tools for complex leak detection. A specialist invests in technology and training to find the leak quickly and accurately, saving time and money.
What should I do if I suspect I have a water leak?
If you suspect a leak, act fast. If you can safely access it, turn off your home's main water shut-off valve to prevent further damage. Then, call us immediately. Our emergency team can professionally locate the leak, ensuring your home is protected.
