Your Trusted Sydney Leak Detection Experts

A hidden water leak is more than a nuisance; it's a silent threat to your property. Whether it's a water bill that has inexplicably skyrocketed, the appearance of a mysterious damp patch on your wall, or the faint sound of running water, the uncertainty is stressful. Unseen and unfixed, a minor leak can quickly escalate, causing significant structural damage, fostering unhealthy mould growth, and leading to costly, disruptive repairs. You need more than a guess; you need precision, expertise, and immediate peace of mind. That's where GPS Gas Plumbing Services comes in. We are not general plumbers who happen to find leaks; we are dedicated leak detection specialists. Our primary focus is locating the exact source of your water leak non-invasively, saving you from the destructive guesswork of digging up floors or tearing down walls. While we are also fully licensed gas fitters, our specialisation in water leak detection provides evidence-based results using state-of-the-art diagnostic technology.

Our Comprehensive Leak Detection Services

At GPS Gas Plumbing Services, we use state-of-the-art tools and proven techniques to find and fix any type of leak.

Icon for underground pipe leak detection

Underground & Under-Slab Leaks

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.

Icon for bathroom and kitchen leak detection services

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.

Pool & Spa Leaks

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.

Gas Leaks

Gas leaks are a serious safety risk. As licensed gas fitters, our technicians perform thorough inspections to safely detect and facilitate the repair of any gas leak with the urgency it requires.

Find Leaks Fast with Advanced Technology

We use the industry's most sophisticated tools to find water leaks accurately without damaging your property.

Acoustic Sensors: Highly sensitive listening devices allow us to hear the distinct sound of water escaping from pressurised pipes, even deep underground or within walls.
Thermal Imaging: Our infrared cameras detect subtle temperature differences in walls and floors, revealing hidden moisture from leaks that are invisible to the naked eye.
Tracer Gas Detection: For elusive leaks, we use a safe, non-toxic gas that can escape through the smallest crack in a pipe. A sensitive electronic "sniffer" detects the gas, pinpointing the location.
CCTV Inspection Cameras: We use tiny, waterproof cameras to see inside your pipes, allowing us to identify cracks, blockages, or breaks without any guesswork.

This technology allows us to work efficiently, saving you time, money, and the stress of unnecessary property damage.

Warning Signs of a Hidden Water Leak

As a homeowner, it’s important to know the signs of a potential leak. Call us if you notice any of the following:

Sudden Spike in Water Bills: If your bill is unexpectedly high but your water usage hasn't changed, you likely have a leak.
Damp or Discoloured Spots: Check for damp patches, water stains, or peeling paint on walls, ceilings, or floors.
Mould or Musty Smells: A persistent musty odour or visible mould growth often indicates a hidden moisture source from a leak.
Sound of Running Water: If you can hear water running when all taps and appliances are off, it's a clear sign of a leak.
Low Water Pressure: A sudden drop in pressure can indicate a breach in your water service line.

Jane Wills

Had a kitchen tap that wouldn’t stop dripping no matter how hard I turned it off. Called GPS Gas Plumbing Services and they booked me in the same day. He replaced the worn-out washer, tightened everything up, and even checked the other taps in the house to make sure they were fine. Really tidy job — left the bench clean and dry. Happy with the service.

Frequently Asked Questions About Leak Detection

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.

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.

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.

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.

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.

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.
