Professional Leak Detection in Illawarra
Expert plumbing leak detection across Wollongong, Kiama, Shellharbour and the greater Illawarra region. Using advanced non-invasive technology to locate hidden water leaks quickly and accurately.
Plumbing leak detection is a specialist service that uses acoustic listening devices, thermal imaging, and pressure testing to locate hidden water leaks in pipes, walls, floors, and underground without causing damage to your property. Professional leak detection in Illawarra typically costs between $150-$400 and can save homeowners thousands in water damage repairs and excess water bills. Signs you need leak detection include unexplained high water bills, damp patches, musty odours, or the sound of running water when all taps are off. We also provide non-invasive leak detection for unit complexes and strata schemes across the Illawarra, where pinpointing leaks between lots is critical to attributing repair costs correctly.
Advanced Leak Detection Methods
Plumbing Creations uses the latest leak detection technology to find hidden water leaks quickly and accurately, saving you time and money on unnecessary repairs.

Our advanced acoustic and thermal technology locates leaks without damaging your walls, floors, or landscaping. We pinpoint the exact location before any digging or cutting.
Pressure Testing
Comprehensive pressure testing identifies leaks in your plumbing system, including underground pipes, hot water systems, and concealed pipework throughout your property.
Thermal Imaging
Infrared thermal cameras detect temperature variations caused by water leaks behind walls and under floors, revealing hidden moisture without destruction.
Emergency Response
Water leaks don't wait for business hours. Our emergency leak detection service is available 24/7 across Illawarra to minimise water damage and prevent costly repairs.
Save Money
Early leak detection prevents water wastage, reduces your water bills, and avoids expensive structural damage. Most leak repairs cost far less than water damage restoration.
Licensed & Insured
Fully licensed plumbers with comprehensive insurance. All work guaranteed and compliant with Australian plumbing standards and NSW regulations.
Types of Water Leaks We Detect
From underground pipes to concealed wall cavities, our team has the expertise and equipment to locate any type of water leak in your Illawarra property.
Underground Water Leaks
Hidden leaks in underground water mains and supply pipes can waste thousands of litres daily. We use acoustic detection to locate these leaks precisely without excavating your entire yard.
Warning Signs:
- Unexplained wet patches in yard
- Higher than normal water bills
- Low water pressure
- Sound of running water underground
Slab Leaks
Leaks under concrete slabs are particularly challenging. Our thermal imaging and acoustic equipment can detect water movement beneath concrete floors without breaking through.
Warning Signs:
- Warm spots on floor
- Cracks in flooring or walls
- Mould or mildew smell
- Foundation cracks
Wall & Ceiling Leaks
Concealed leaks within walls and ceilings can cause significant structural damage and mould growth. We detect these early using moisture meters and thermal cameras.
Warning Signs:
- Damp patches on walls
- Peeling paint or wallpaper
- Stained ceilings
- Musty odours
Hot Water System Leaks
Leaks from hot water systems and associated pipework require prompt attention. We inspect tanks, valves, and pipework to identify the source and recommend repairs.
Warning Signs:
- Puddles near hot water unit
- Rusty water
- Inconsistent water temperature
- Higher energy bills

What leak detection and repair costs
Detection and repair are two different jobs. Finding a concealed leak properly is almost always cheaper than excavating speculatively along the whole run.
| Job | Typical range | What affects it |
|---|---|---|
| Exposed or accessible pipe | $250 – $500 | Under a sink, in a cupboard, on an external wall. |
| In-wall pipe | $400 – $800 | Includes opening and making good the wall. |
| Underground, with excavation | $800 – $2,500+ | Driveways, paving and deep runs push this higher. |
| Leak detection (before any repair) | $250 – $600 | Acoustic and thermal. Finds it without digging up the yard first. |
These are typical price ranges for the Illawarra and NSW, drawn from published 2026 industry pricing data — not a quote, and not our fixed prices. What your job actually costs depends on access, the age and condition of the plumbing, parts, and whether it is after hours. We give you a fixed price before we start work, so you are never guessing.

Find it first, or start digging?
The cost of a leak repair is mostly the cost of getting to it. That is why locating it precisely changes the number so much.
| Situation | Locate first | Dig and hope |
|---|---|---|
| Leak under a slab | Acoustic and thermal narrow it to a small area | Open the floor and follow the pipe |
| Leak under a driveway | One excavation, in the right place | Reinstating concrete is the biggest line on the invoice |
| Leak in a wall | One patch to make good | Several patches, one of which is right |
| Total cost | Detection fee plus one targeted repair | Unpredictable, and usually higher |
| Insurance | A written report on the cause if they ask for one | Harder to evidence |
The meter test: find a hidden leak for free
Before you book anyone, do this. Turn off every tap and appliance in the house — including the washing machine, the dishwasher and any irrigation. Go to the water meter and watch the smallest dial for a few minutes. If it is still turning, water is going somewhere it should not.
Other signs worth acting on:
- An unexplained jump in the bill
- A warm patch on a floor — that is a hot water line
- A musty smell in a room, or paint bubbling on a wall
- A patch of lawn that stays green through dry weather
- The sound of running water when nothing is on
A slow leak running for months does far more damage than the repair would have cost, and many insurance policies treat gradual damage differently from a sudden burst. That distinction is the reason not to sit on it.
How we actually find it
Acoustic equipment listens for the sound of water escaping under pressure, which carries through pipe and slab. Thermal imaging finds the temperature difference a hot water leak creates. Pressure testing isolates which line is losing water. On drainage rather than pressure lines, a CCTV camera does the same job visually. Between them, we get to a small area rather than a general direction — and that is the whole point.
Why Illawarra homes leak
- Age. Post-war stock in the older Wollongong suburbs, and the 1980s Gainsborough Estate homes in Kiama Downs now at around forty years — which is when original runs start letting go.
- Salt. Coastal properties at Gerroa, Minnamurra and Werri Beach corrode faster, particularly fittings and valves.
- Ground movement. The escarpment side moves after heavy rain, and buried pipework does not flex. Underground failures often show up weeks after a big weather event rather than during it.
- Water hammer. That bang when a tap or washing machine valve shuts is a pressure spike hitting the pipework repeatedly. Over years it works joints loose. Cheap to fix, and worth doing.
- Excessive mains pressure. If you have had more than one unexplained failure, get the pressure checked. It explains a lot of otherwise random plumbing problems.
