Signs You Have a Hidden Leak

Hidden leaks can cause thousands of dollars in damage before they're visible. If you notice any of the following, call us for a leak detection inspection.

Unexplained increase in water bills
Sound of running water when taps are off
Damp or wet patches on walls or ceilings
Mould or mildew without an obvious source
Hot spots on floors (hot water pipe leak)
Cracking or lifting floor tiles
Soft or spongy areas in lawns or gardens
Low water pressure throughout the property

The Cost of Doing Nothing

A 1mm pinhole leak at normal mains pressure loses around 1,000 litres per day. That's $2–$4 per day in water costs alone — before you factor in structural damage to walls, floors, and foundations.

Most hidden leaks are found and repaired in a single visit. The sooner you call, the less damage — and the lower the repair bill.

How we find it

Our Detection Methods

We use specialist equipment to locate leaks precisely — so repairs are targeted, not exploratory.

Acoustic Leak Detection

Specialist listening equipment amplifies the sound of water escaping from pressurised pipes. We can pinpoint leaks inside walls, under floors, and underground — without opening anything up.

Thermal Imaging

Thermal cameras detect temperature differences caused by moisture and water movement. Ideal for finding leaks behind tiles, inside wall cavities, and under concrete slabs.

Pressure Testing

We isolate sections of your plumbing and test pressure to confirm whether a leak exists and narrow down its location before using detection equipment.

Pipe Relining

Where excavation isn't practical, we can reline damaged pipes from the inside — restoring full flow without digging up your yard or breaking your slab.

What to expect

How We Work

Initial Assessment

We discuss the symptoms — high bills, damp patches, sounds of running water — and determine the most likely leak location.

Detection

We use acoustic and/or thermal equipment to locate the leak precisely. In most cases this takes 1–2 hours.

Report & Quote

We show you exactly where the leak is and give you a fixed quote to repair it before any work starts.

Repair

We repair the leak with minimal disruption — targeted access only, no unnecessary digging or demolition.

Test & Confirm

We pressure-test the repaired section to confirm the leak is fully resolved before we leave.

Common questions

Leak Detection FAQs

How do you find a hidden water leak?

We use acoustic listening equipment to detect the sound of water escaping from pipes, and thermal imaging cameras to identify temperature differences caused by moisture. These non-invasive methods let us pinpoint leaks without unnecessary digging or demolition.

How much does leak detection cost?

Leak detection starts from around $250–$450 for a standard residential inspection. Complex under-slab or underground detection may be higher. We quote before we start — call 0487 810 593.

Will you need to break up my slab or walls?

In most cases, no. Our detection equipment locates the leak precisely so that any access point is minimal and targeted. We only open walls or slabs when absolutely necessary — and we'll always discuss this with you first.

My water bill has gone up — could I have a leak?

Yes. An unexplained increase in your water bill is one of the most common signs of a hidden leak. Even a small continuous leak can waste thousands of litres per month. Call us for a leak detection inspection.

Leak Detection Reviews

Found a hidden slab leak without tearing up the floor

“My water bill had doubled but I couldn't see any obvious leak. Terry used acoustic detection equipment and pinpointed a slab leak under the laundry in about 20 minutes. Minimal concrete cutting, pipe repaired and re-tested the same day. Saved me thousands compared to what I'd been quoted elsewhere.”

Problem

Water bill doubled with no visible leak — suspected slab leak under the laundry floor

Solution

Acoustic leak detection pinpointed the exact location; minimal concrete cutting, pipe repaired and pressure-tested

Resolved in1 hour 45 minutes

Thermal imaging found a leak inside the wall

“I could hear water running but couldn't find where it was coming from. Terry used thermal imaging and found a pinhole leak inside the bathroom wall. He opened a small access panel, repaired the pipe and patched the wall. No major demolition needed — I was so relieved.”

Problem

Audible water running inside the bathroom wall with no visible source — suspected pinhole leak

Solution

Thermal imaging camera located the pinhole leak precisely; small access panel cut, pipe repaired, wall patched

Resolved in1 hour 30 minutes
