Leak Detection Brisbane Northside — Find Any Leak Fast
A hidden leak can waste thousands of litres of water and cause serious structural damage before it's ever visible. Our plumbers use acoustic listening devices and thermal imaging cameras to locate leaks precisely — under slabs, inside walls, and underground — without unnecessary damage. We find it first, then fix it.

Mystery Water Bill — Slab Leak Under Kitchen
The Problem
Homeowner's water bill had tripled over three months but nothing visible was leaking. Other plumbers couldn't find it. 'We thought maybe it was the meter, but the bill just kept climbing.'
Our Solution
Used acoustic listening equipment along the slab. Located a pinhole leak in a copper pipe running under the kitchen floor — completely invisible from above. Accessed via the most minimal cut possible.
The Result
Pipe repaired, slab patched. Water bill back to normal the following quarter. Homeowner estimated they'd lost over $400 in wasted water before we found it.
Wet Carpet in Bedroom — Wall Leak
The Problem
Wet patch appearing on bedroom carpet with no obvious source. No visible plumbing in that area. Builder and painter both suggested it was a waterproofing issue.
Our Solution
Thermal imaging camera identified a temperature differential in the wall cavity — a slow drip from a join in the cold water pipe behind the gyprock. Opened a small access panel to repair.
The Result
Leak sealed, panel reinstated, carpet dried out fully within a week. Saved the homeowner from a full bathroom re-waterproofing that would have cost thousands and been the wrong fix.
Commercial Premises — Hidden Irrigation Leak
The Problem
A commercial property manager noticed the water meter was spinning even overnight when the building was empty. Suspected an underground irrigation leak but the grounds were extensive.
Our Solution
Isolated zones systematically and used acoustic detection to pinpoint the exact location — a cracked irrigation pipe 600mm underground in the garden bed.
The Result
Pipe repaired with a single targeted dig. Water use dropped immediately. The fix cost a fraction of what ongoing water waste would have cost.
Frequently Asked Questions
How do you find a leak without breaking walls or floors?
We use a combination of acoustic listening devices, thermal imaging cameras, and tracer gas to locate leaks precisely before any access is needed. This means we only open what's necessary to make the repair.
What causes slab leaks in Brisbane?
Brisbane's clay-heavy soils shift with wet/dry cycles, which stresses pipes running through slabs. Older copper pipes also develop pinhole corrosion over time. Slab leaks are often silent — the only sign is a rising water bill.
How much does leak detection cost in Brisbane?
Pricing depends on the complexity of the search. We provide upfront quotes before starting. Call 1300 158 895 for an assessment — many leaks are found and repaired in a single visit.
My water bill has spiked — could it be a leak?
Yes, this is one of the most common signs of a concealed leak. Check your water meter with all taps off — if the dial is moving, you almost certainly have a leak somewhere. Call us and we'll find it.
