When Water Leak Detection Can't Wait
A slightly higher water bill on its own isn't usually urgent. These signs point to something active and worth chasing now:
- The water meter still turning with every tap in the house off
- Damp patches on a wall or ceiling with no obvious cause
- A musty smell that won't shift, especially near a bathroom or laundry
- A warm patch on the floor, which can mean a leaking hot water pipe under the slab
- The sound of running water somewhere in the house when nothing's on
If water's actively pooling or spraying right now, that's burst & leaking pipes territory; shut the water off at the meter and call.
The Full Scope of Water Leak Detection
We use non-destructive methods first, so we're not opening walls on a guess. Cutting into plaster or brick is the last step, not the first, once we're confident exactly where to look.
Acoustic listening. Specialist gear picks up the sound of water moving through a pipe you can't see, narrowing the search fast.
Meter isolation testing. Turning everything off and watching the meter confirms whether there's a leak at all before we go further.
Moisture and thermal checks. Reading temperature and dampness across a wall or slab points to where the pipe is actually running.
Pinpointing before opening anything. Once the leak's located precisely, we tell you exactly what access is needed before any cutting starts.
Water Leak Detection Pricing, Without the Guesswork
How hidden the leak is drives most of the price, and we'll talk through it with you before you approve anything.
- Whether the pipe is exposed, behind a wall or beneath the slab
- Specialist equipment needed, like acoustic or thermal gear
- Property size and how many suspected points there are
- Access, roof space, subfloor or a tight service area
Older double-brick construction, common on Mortdale's pre-war and 1950s blocks, runs pipework inside a solid wall with no cavity to reveal a leak early.
Tracing it accurately can take a little longer than on a newer timber-framed home.
You'll have that number in hand before any tool comes out, whichever of these turns out to apply.
Water Leak Detection, the Mortdale Version
Around Victoria Avenue and through the older parts of Mortdale, houses are commonly built double-brick or in fibro, put up across the suburb's pre-1940s and 1940s-to-1960s growth waves.
Solid masonry like that doesn't have the wall cavity a timber-framed home has, so a leaking pipe inside the wall has nowhere to show itself early.
Water tracks sideways along a slab, or down inside the brick, instead of appearing where the pipe actually is. It's why acoustic and thermal tracing matter more here than a visual check alone.
The Fine Print That Protects You
Diagnosing and repairing a water leak is licensed plumbing work under NSW rules, and that's who you'll get, start to finish.
Tracing a leak doesn't require opening a wall first. The non-destructive methods above are how we confirm the location before any cutting is agreed, so you're never paying to have something opened on a guess.
That plain-English explanation applies whether the repair turns out to be a quick fitting swap or a section of pipe that needs replacing. Either way, you'll know what you're agreeing to and why, before we agree to anything.
Our Callout Process for Water Leak Detection
Your part takes one phone call. Tell us what's happening and where you are. We handle everything from that point on.
While we're on the way, you're not alone. We'll tell you what to turn off, what to move and what to leave well alone.
You make one decision. We hand you a fixed price and you say yes or no. No pressure, no jargon, no fine print.
Then you go back to your night. We fix it, test it, leave it verified safe and see ourselves out quietly.
Locating a leak is usually a same-visit job. The repair itself, if the pipe's easy to reach, often happens straight after; a leak buried deep in a slab can mean scheduling the opening-up work separately.
Why This Is Our Kind of Job
A hard-to-find leak is exactly the kind of job that rewards genuine skill over guesswork, because the longer it runs unnoticed, the more it can affect the structure around it. Guesswork here means opening the wrong wall, twice.
It's backed by the Lifetime Labour Warranty on every job, whether that's a quick trace or a full repair. The same standard applies to a small fix as a full afternoon on-site.
Servicing Mortdale and Surrounding Areas
Older brick housing stock isn't unique to one street here. From Victoria Avenue through to the blocks nearer Hurstville Golf Course, we're regularly tracing leaks through the same kind of solid-wall construction, and the approach doesn't change from one street to the next.
That's true just as much next door. Beverly Hills, Riverwood and Peakhurst are all part of the same regular run, with the same non-destructive approach on every visit.

After-Hours Water Leak Detection FAQs
Common questions from Mortdale homeowners chasing down a hidden leak.
How long does a water leak detection job usually take?
An open leak, an exposed pipe or a running fixture, is usually found within the visit. One hidden behind a solid wall or under a slab can take longer to pin down accurately, and we'll say so as we go rather than guess.
Do you charge a call-out fee for water leak detection?
No call-out fee. A licensed plumber comes out, does the diagnostic work, and you only pay for what's agreed afterward.
Will one visit be enough to sort it?
Tracing the leak usually happens in one visit. Whether the actual repair is same-day too depends on what we find, and we'll always tell you before booking a second visit.
What happens if the job turns out bigger than quoted?
We stop and walk you through what's changed, with a fresh number for the extra scope. Nothing proceeds until you say go.
Will the problem come back after water leak detection?
If our repair fails again, we come back. No questions. No cost.
Are you insured for water leak detection work?
Yes, fully licensed and insured on every visit, whether it's a quick check or a full trace-and-repair.
