Leak Detection Specialists in Newcastle
Hidden water leaks are found fast with thermal imaging and acoustic testing, then repaired by licensed local plumbers.
Why Locals Call Us First for Leaks
"I've been looking for this leak for about 18 months and have had 6 or 7 tradesmen here to try and locate it. In an hour, you've found it"
Newcastle's Water Leak Detection Specialists
A hidden water leak rarely announces itself. It shows up as a climbing water bill, a damp patch that never dries, a musty smell, or the sound of running water when every tap is off. Our team locates these leaks quickly and accurately, so the damage stops before it spreads. Leak detection is part of our wider Newcastle plumbing services, and it’s the work our specialists are known for.
We’re leak detection specialists, not general plumbers who guess. We use acoustic leak detection, which is listening equipment that picks up the sound of water escaping a pressurised pipe, alongside thermal imaging cameras that read temperature differences behind walls and under floors, and moisture meters that measure how far water has travelled. Together, these tools pinpoint the source without cutting open walls or digging up your garden.
Backed by 25 years of plumbing experience, fully licensed and insured, we find and repair leaks across Newcastle homes and businesses, along with the Central Coast and Port Stephens. Most leaks are located in a single visit, and you get a written quote before any repair begins.
How We Find Hidden Leaks
We match the detection method to the symptom. These are the tools our specialists rely on, and when each one is used.
- Acoustic Leak Detection: Acoustic equipment amplifies the sound of water escaping a pressurised pipe, even through concrete or tile. It’s the fastest way to trace a leak inside a wall cavity or under a slab without opening anything up.
- Thermal Imaging: A thermal camera reads the temperature difference a leak creates behind a surface. Warm water under a floor or cool, damp inside a wall shows up clearly on the image, which lets us mark the spot before we touch it.
- Moisture Meters: Moisture meters confirm how far water has spread through floors, walls and subfloors. They separate an active leak from an old stain, so the repair targets the real source rather than the symptom.
- Pressure Testing: For supply and drainage lines, we isolate sections and test the pressure to confirm which pipe has failed. This is how we verify a suspected slab leak or an underground water leak before recommending the fix.
Our Leak Detection Advantage
Finding a hidden leak quickly comes down to the right equipment in experienced hands. These are the things that let our team locate leaks that other plumbers walk away from and repair them without turning your property upside down.
Advanced technology
Thermal imaging, acoustic sensors and moisture meters are used together, so a leak is pinpointed to the exact spot rather than a rough area.

What We Detect Leaks in
Water finds the smallest gaps, so leaks turn up in places you would never expect. Our team detects and repairs leaks across every part of a property:
- Water leaks in walls and underground. Concealed pipes that can leak for months. Our specialist water leak detection traces the line and marks the failure point before any digging.
- Bathroom and shower leaks. Our bathroom water leak detection finds whether water is escaping the membrane, the drain or a supply pipe. We also handle shower repairs.
- Slab and subfloor leaks. Warm floors or a rising bill with no visible water. Our subfloor leak detection case study shows how we trace them.
- Balcony and pool leaks. We test both and repair the cause, from pool leak detection to balcony leaks.
Wherever the water is escaping, the priority is the same: pinpoint the exact source before any repair, so the fix lands the first time.
Leak Detection Specialists Newcastle can rely on
Leak Hunters started with one idea: find the problem properly before touching anything. Too many Newcastle homeowners had already paid tradespeople who patched the symptom without finding the source, so we invested in the equipment to do it differently.
Signs your property is hiding a leak
Water leaks don’t always leave a puddle. The early signs are easy to explain away:
- A water bill that keeps climbing for no clear reason
- Damp spots or stains that won’t dry out
- A musty smell, or mould on walls or ceilings
- The sound of running water when everything is off
- Warm patches on the floor, which often point to a slab leak
With over 25 years in Newcastle plumbing, our specialists use thermal imaging, acoustic listening devices and moisture meters that most plumbers don’t carry, so leaks that have run for months get found. We’re straight with you on cost, you get a written quote before any work begins, and the same licensed team both detects and repairs the leak. Every leak we locate is repaired by our Newcastle plumbing team, with the findings explained before any work is quoted.

Frequently Asked Questions
Can you find leaks without damaging my property?
Yes. Our non-invasive leak detection uses thermal imaging and acoustic equipment to locate most leaks through walls, floors and balconies with no demolition. If access is ever needed, we keep it to the smallest possible area.
How long does it take to find a leak?
Most residential leaks are located within 1-2 hours. Complex or multiple leaks may take longer, but we’ll keep you informed throughout the process.
Do you repair the leaks you find?
Yes. We’re licensed plumbers, so the same team that detects the leak can repair it, often on the same day. You’ll have a written quote before any repair begins.
How much does leak detection cost?
Cost depends on the type of leak and how much investigation it needs. We give you an upfront price before starting, and you approve the repair quote separately, so there are no surprises.
What is acoustic leak detection?
Acoustic leak detection uses sensitive listening equipment to pick up the sound of water escaping a pressurised pipe, even under concrete or tile. It lets us trace a hidden leak to its exact position without guesswork.
Can you detect underground and slab leaks?
Yes. We combine pressure testing, acoustic detection and thermal imaging to find underground water leaks and slab leaks, then confirm the location before any concrete or paving is disturbed.
Can you detect leaks in swimming pools?
Yes. Our specialists test the shell, plumbing and fittings to find where a pool is losing water. Our pool leak detection service covers this in detail.
