How we detect leaks.

We use specialised equipment to locate leaks accurately without tearing apart your property.

Acoustic Leak Detection

Pressurised water escaping through a crack or hole creates sound. Our acoustic listening equipment amplifies these sounds, allowing us to pinpoint the exact location of a leak even when it is buried underground or hidden behind a wall. This method is particularly effective for water mains leaks and underground supply pipes.

Thermal Imaging

Thermal cameras detect temperature differences on surfaces caused by water leaking behind walls or under floors. Hot water pipe leaks show as warm spots, while cold water leaks appear as cool patches. This technology lets us see what is happening behind surfaces without cutting any holes.

Pressure Testing

We isolate sections of your plumbing system and test them under pressure to determine whether there is a leak and where it is located. A pressure drop confirms a leak in that section. Combined with acoustic detection, this narrows down the location with precision.

CCTV Pipe Inspection

For drain and sewer leaks, we use CCTV drain cameras to inspect the inside of pipes and identify cracks, breaks, or joint failures that are causing leaks. This is essential for diagnosing problems in older earthenware pipes common in many Canberra suburbs.

How it works.

1. Call us

Describe the signs you have noticed. High water bills, damp patches, musty smells, or water where it should not be. We will ask questions to understand the situation and schedule a visit.

2. We investigate

Using a combination of acoustic, thermal, and pressure testing equipment, we systematically locate the leak. You get a clear explanation of where the leak is, what is causing it, and an upfront price to repair it.

3. We repair

Once located, we repair the leak at the source. Whether it is a burst pipe in the wall, a failed joint underground, or a corroded fitting, we fix it properly and test the system to confirm the problem is resolved. All work is guaranteed.

Signs you may have a hidden leak.

Many leaks go undetected for months or even years, slowly causing damage to your property's structure, foundations, and finishes. Here are the warning signs to watch for.

Unexplained water bill increase

If your water usage has not changed but your bill has spiked, a hidden leak is the most likely cause.

Water meter keeps running

Turn off all taps and appliances, then check your water meter. If it is still spinning, water is escaping somewhere.

Damp patches on walls or ceilings

Discolouration, bubbling paint, or soft spots indicate water behind the surface.

Musty or mouldy smells

Persistent dampness creates conditions for mould growth, even if you cannot see it.

Warm spots on the floor

A hot water pipe leak under a concrete slab creates noticeable warm areas on the floor surface.

Cracking or movement in walls

Water undermines soil beneath foundations, causing settling and cracking over time.

If you notice any of these signs, do not wait. A small leak today becomes a major repair tomorrow. Properties across Civic and the Inner North, Woden, and Belconnen are particularly susceptible due to the age of the plumbing infrastructure.

Leak detection FAQs.

The things Canberra locals ask us most. Still not sure? Just give us a call — we are happy to talk it through.

We use a combination of acoustic listening devices, thermal imaging cameras, moisture meters, and pressure testing to locate hidden leaks without unnecessary demolition. These tools allow us to pinpoint leaks behind walls, under concrete slabs, and underground with minimal disruption to your property. In most cases, we can locate the leak without cutting a single hole.
Not necessarily. Our non-invasive detection equipment can locate underground leaks without broad excavation in many cases. If the leak is in an underground pipe that needs physical repair, we will need to excavate, but only in the precise location of the leak. No exploratory trenching or guesswork digging. Give us a call and we will talk through your situation.
The clearest indicator is an unexplained increase in your water bill. Other signs include the sound of running water when all taps are off, damp or discoloured patches on walls and ceilings, musty smells, warm spots on the floor (from hot water leaks under slabs), and cracks appearing in walls or foundations. If your water meter is spinning when nothing is running, you almost certainly have a leak somewhere. Call us and we will help you work it out.
Leak detection costs depend on the complexity of the investigation. A straightforward assessment differs from a complex job requiring acoustic detection, thermal imaging, or CCTV pipe inspection. Every home and every job is a little different, so we always provide upfront pricing before starting any investigation. Call us, tell us what is happening, and we will explain exactly how the pricing works for your situation.
