Licensed & local
Trusted Leak Detection Specialists
Our licensed team has located and repaired hidden leaks across the inner-north for a decade, with Lic. #333997 from Master Plumber South Australia, full insurance, and acoustic and thermal tools that pinpoint the source before any access cutting begins. Fixed Upfront Pricing and our Lifetime Labour Warranty back every job:
Our team finds and repairs the full range of hidden water and gas leaks across local properties, using non-invasive acoustic, thermal, and pressure-testing equipment that keeps floors, walls, gardens, and slabs intact through diagnosis:
Hidden Water Leak Detection
Acoustic listening tools locate concealed water leaks inside wall cavities, ceiling spaces, and beneath suspended timber sub-floors, pinpointing the exact source before any access cutting begins inside the property itself.
Slab Leak Detection
Thermal imaging and pressure testing pick up the moisture signature of leaks running beneath concrete slabs, so the source is confirmed before any flooring or concrete is cut for repair.
Gas Leak Detection
Suspected gas leaks get full pressure-testing and acoustic detection at the meter and internal fittings, with safe isolation and licensed [gas fitting](/gas-fitting/) repair completed on the same visit where possible.
Acoustic and Thermal Location
Specialist imaging picks up temperature differentials and pressure noise from active leaks behind sealed walls or floors, often resolving hidden cases that turn up alongside symptoms of [blocked drains](/blocked-drains/) elsewhere.
Leak Repair After Detection
Once the source is pinpointed, the repair is completed to AS/NZS 3500 standards with minimal access cutting, full pressure testing, and the workmanship warranty applied to the finished job.
Why it matters
Why Leak Detection Choice Matters
Hidden leaks run for weeks or months before anyone spots them, and by the time a water bill spikes or damp shows on a ceiling, the real damage to your home structure is already underway:
Undetected leaks waste water and steadily drive up your bill
Wall, ceiling, and timber damage compounds the longer a leak runs
Slab moisture leads to mould, rot, and rising-damp problems
Insurance claims often need timely action to stay covered
Non-invasive detection avoids the cost of speculative excavation
Emergency
When a Hidden Leak Becomes an Emergency
Not every leak is an after-hours callout, but the scenarios below are. If any of these are happening at your property right now, treat it as an urgent call rather than a routine booking:
Gas smell anywhere inside or outside the property
Water staining spreading across ceilings, walls, or cornices
Unexplained spike in your water bill of 50% or more
Damp patches or warm spots on floors or under carpet
Our team responds within the hour where availability allows. While you wait, turn off water at the mains or gas at the meter to limit further damage to the home.
Common faults
Common Hidden Leak Problems We Fix
The leak calls our team takes across the inner-north follow a few recurring patterns tied to the local housing stock. These are the hidden leak problems we locate most often:
01
Pinhole leaks in galvanised water lines
Inter-war cottages and Housing Trust homes across the inner-north were plumbed in galvanised steel, with pinhole leaks now developing behind walls before [burst pipes](/burst-pipes/) follow.
02
Gas leaks at legacy fittings
Many older inner-north homes still run cooktops, hot water units, and heaters off original gas meter assemblies and internal fittings, where hairline leaks at the joints turn up on pressure testing.
03
Cracked clay drain joints
Sewer connections laid through the 1940s, 1950s, and 1960s build-out used earthenware clay, and the cracked joints leak slowly into garden beds and under-slab cavities below the property.
04
Hidden bathroom and laundry leaks
Leaks inside walls behind showers, baths, and laundry tubs cause damp damage often blamed on condensation, and our team diagnoses the source and repairs from the cleanest access point.
Our process
How Our Leak Detection Process Works
Our leak detection process is built to be non-invasive and predictable, with each step protecting your home and your budget. Here is what to expect on the day, from first call through to handover:
1
Initial Assessment
Our team listens to the symptoms by phone, then on site we inspect visible damage, check the water meter, and identify the likely zone where the hidden leak is occurring.
2
Non-Invasive Detection
Acoustic listening, thermal imaging, and pressure testing together pinpoint the leak source so walls, floors, and slabs stay intact during diagnosis, with any necessary access cuts kept to a minimum.
3
Upfront Quote
Once the leak is pinpointed, you get Fixed Upfront Pricing for the access work and the repair, with no hourly rates and no surprise charges quoted at the end.
4
Repair, Test, Handover
A licensed plumber completes the repair, pressure-tests the line under load, restores any access cuts made, walks you through the finished work, and confirms your warranty before leaving site.
