How Do You Know a Leak Is Hiding?
A leak rarely announces itself. It shows up as evidence first, and the pattern tells you where to look:
- A water bill that climbs even though nothing about your water use has changed
- Paint that bubbles, or a musty smell that returns whatever the weather
- Warm patches underfoot, often a sign of hot water pipes weeping below
- The meter ticking over with every tap in the place turned off
- Faint running water sounds inside a wall, clearest in the quiet of night
The meter test is the one you can do yourself: note the reading, use nothing for an hour, read it again. Movement with nothing running means a leak somewhere inside your boundary.
How We Trace a Leak
- 01
Isolate and confirm
We shut the supply and check the meter to prove the leak is real and on your side of it, not the street main.
- 02
Narrow the zone
The listening equipment works along the pipe run while the line stays pressurised, and moisture meters map the wet spread across walls, floors and cabinetry.
- 03
Pinpoint the pipe
The locator traces the buried line's path and depth, so the leak gets marked to a spot, not a corner of the house.
- 04
Quote the fix
You get the findings, the marked-up location and a fixed price for the repair before a single tile or board comes up.
What Changes the Cost of Leak Detection?
The biggest driver is depth: a leak under a timber floor you can crawl beneath is a faster trace than one sealed under concrete. The pipe material matters too, because old galvanised lines can be corroded along their whole length rather than at one point. Access to the suspected zone, and how many rooms sit between the meter and the wet patch, round out the figure.
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.

What Customers Say
[The team] came to our home to inspect a water leak yesterday. … They were able to identify and service the leak and were happy to talk us through the process.
When We're Not the Right Call
When the water is coming from above. A failed shower membrane or water getting in through the walls or roof is a waterproofer's or builder's work, and the trace shows that before you pay for a pipe repair that solves the wrong problem.
Related work when the trace finds damage: a cracked drain run is confirmed with CCTV drain inspection, a hot water unit doing the leaking is handled under hot water, and a smell rather than a stain goes to gas leak detection. For urgent bursts that cannot wait for a trace, the emergency plumber page covers what happens on the night.
Leak Detection FAQs
Can you find a leak under a concrete slab in a Wallsend home?
Yes. The listening equipment hears a pressurised leak hissing beneath a slab, and the pipe locator maps the run underneath first so we open one small hole, not a trench. You see the marked spot and the fixed quote before any concrete comes up.
How accurate is the trace before anything gets opened up?
Very. The locator gives a line on the floor and a depth for the pipe, and the listening gear confirms the loudest point along it. We mark that spot for you, so the repair targets the fault rather than a guess somewhere near it.
Should I shut the water off at the meter while I wait?
If water is spreading anywhere near wiring or timber, yes, shut it at the meter and keep it off. For a slow damp patch you have watched for days, leave it on so the leak stays audible and we can pinpoint it faster.
Is a hidden leak always a big repair?
No. A trace can end at a single corroded fitting or a perished washer, which is a small repair. The costly ones are usually buried supply lines in older homes, and even those can often be rerouted above ground instead of excavated.
