Licensed & local
Trusted Leak Detection Specialists
Our licensed team has located and repaired hidden leaks across the hills foothills for a decade. Lic. #333997 with Master Plumber South Australia, fully insured, and equipped with acoustic and thermal tools that pinpoint the source before any access work begins. Fixed Upfront Pricing and Lifetime Labour Warranty:
Our team locates and repairs the full range of hidden plumbing leaks across local homes using non-invasive acoustic, thermal, and pressure-testing tools that protect floors, walls, gardens, and slabs during the diagnosis stage:
Hidden Water Leak Detection
Acoustic listening locates concealed water leaks inside walls, ceiling cavities, and under suspended timber floors, pinpointing the exact source before any access cutting begins in the home.
Slab Leak Detection
Thermal and acoustic tools locate leaks beneath concrete slabs without breaking up the whole floor, so the exact source is confirmed before any concrete is cut for repair.
Gas Leak Detection
Suspected gas leaks get pressure-test and acoustic detection at the meter and fittings, with full safety isolation and licensed [gas fitting](/gas-fitting/) repair completed on the same call-out where possible.
Acoustic and Thermal Location
Specialist imaging picks up temperature differentials and pressure noise from active leaks behind sealed walls and floors, with the same diagnosis often resolving leaks tied into [blocked drains](/blocked-drains/).
Leak Repair After Detection
Once the source is pinpointed, the repair is completed to AS/NZS 3500 plumbing standards with minimal access cutting, full pressure testing, and our workmanship warranty on the finished job.
Why it matters
Why Leak Detection Choice Matters
Hidden leaks run for weeks or months before anyone spots them. By the time the water bill arrives or the damp shows on a ceiling, real damage is already done. Detection done properly avoids unnecessary destruction across older hills properties:
Undetected leaks waste water and drive up your bill steadily
Wall, ceiling, and timber damage compounds the longer a leak runs
Slab moisture leads to mould, rot, and rising-damp problems
Insurance claims need timely action to stay covered
Non-invasive tools save the cost of speculative excavation work
Emergency
When a Hidden Leak Becomes an Emergency
Not every leak needs an after-hours callout, but the scenarios listed below do. If any of these are happening at your home right now, treat it as an urgent call straight away rather than waiting for the next routine booking:
Gas smell anywhere inside or outside the property
Water staining spreading across ceilings or walls
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.
Common faults
Common Leak Problems We Fix
The leak calls our team takes follow a few recurring patterns tied to the local housing stock and the foothills terrain. These are the hidden leak problems we locate and repair most often for homeowners around the area:
01
Pinhole leaks in galvanised water lines
Pre-war and early post-war homes near Main Road and the railway station were plumbed in galvanised steel. Unreplaced sections develop pinhole leaks behind walls and under floors, located non-invasively before any [burst pipes](/burst-pipes/) follow.
02
Gas leaks in legacy mid-century fittings
Many mid-century homes still run gas appliances through their original-era fittings and risers. Pressure testing and acoustic detection isolate hairline leaks at joints, with a licensed gas fitter completing the repair on the same visit.
03
Slab and under-floor water leaks
Detached homes across the foothills mix slab-on-ground sections with timber sub-floors. Concealed leaks under either show up as warm spots, damp carpet, or unexplained bill spikes, located with acoustic and thermal equipment.
04
Hidden bathroom and laundry leaks
Leaks inside walls behind showers, baths, and laundry tubs cause damp damage often blamed on condensation. Our team diagnoses the actual source and repairs from the cleanest access point with minimum disruption to the home.
Our process
How Our Leak Detection Process Works on Every Job
Our leak detection process is built to be non-invasive and predictable. Here is what to expect on the day, from the first call through to the final repair and handover at your home:
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 leak is occurring.
2
Non-Invasive Detection
Acoustic listening, thermal imaging, and pressure testing pinpoint the leak source so walls, floors, and slabs stay intact during diagnosis, with any access cuts kept to a minimum.
3
Upfront Quote for Repair
Once the leak is located, you get a Fixed Upfront Price for the access work and the repair, with no hourly rates and no surprise charges at the end.
4
Repair Testing and Handover
A licensed plumber completes the repair, tests the line under pressure, restores any access cuts made, walks you through the work, and confirms your warranty before leaving.
