What Water Leak Detection Covers
The classic giveaway is a meter that keeps creeping forward after every fixture in the house is switched off. It's rarely the only clue.
We track leaks through wall cavities, under slabs, beneath tiles and along buried runs, leaning on acoustic gear and pressure testing before anyone lifts a tile. An unexplained jump in your bill or a ceiling stain that keeps coming back both count as reasons to get us out.
Finding the actual source matters more than patching the symptom. A repair on the wrong section of pipe just means the same damp patch reappears somewhere else a few months later.
The Warning Signs to Act On
Some of these build slowly. Others mean water is moving right now, somewhere you can't see it.
- The meter still ticking over with absolutely nothing running inside
- A quarterly bill that jumped for no reason tied to how you're living
- A ceiling or wall stain that dries out, then reappears days later
- An earthy, damp smell with nothing visibly wet nearby
- A patch of tiled floor that's warm for no good reason, often a hot water line underneath
- A faint hiss behind a wall or under the floor with nothing switched on anywhere
The North Sydney Factor
Old galvanised and clay lines under 19th and early 20th century housing here can fail quietly for a while before they fail loudly. Around Berry Street and the older pockets nearby, that mix of ageing pipe is common enough that a slow hidden leak isn't unusual.
A line like that doesn't always burst outright. It can weep for weeks first, running up a bill and softening a slab before anyone notices.
In a unit block, that slow weep rarely stays with one owner. A leak in an upper floor can track down through a shared wall or ceiling and turn into someone else's water damage before it's ever found.
How We Price Water Leak Detection
What we charge to find a leak depends on a few things, none of which change once you've agreed to a number.
- How accessible the suspected area is
- Water moving through a slab, inside a wall, or along a run underground each need a different approach
- Older galvanised or clay pipe on this kind of job can behave differently under pressure testing, which sometimes adds a bit of time to pin down exactly where it sits
- Whether detection and repair happen in the same visit
- Patching and tidying the area once we've got the pipe in view
We quote the detection separately from the fix, so you know exactly what you're paying for at each stage.
How the Job Runs, Start to Finish
- The call is a conversation, not a queue. Tell us what's happening and we'll tell you what to do right now, before we've even left.
- You'll know we're coming. No vague windows while water's running. We confirm we're on the way and stay reachable until we knock.
- We explain before we quote. What's failed, why, and what fixing it involves, in plain English. Then a fixed price you approve first.
- We finish with a walkthrough. You see the repair, you watch it tested, and we don't leave until the job's verified safe.
A leak with a clear location is often found and fixed the same day. One buried deep under a slab, or hidden behind tiling in an older bathroom, can take a little longer to pin down before repair even starts.
The Fine Print That Protects You
NSW treats leak tracing, and whatever repair follows it, as licensed plumbing work, full stop. That licence is exactly what keeps the job insured if anything goes sideways.
Detection sits entirely on your side of the boundary, well clear of the mains under the street. If the trail leads toward a fault out past your meter, we'll say so rather than dig up ground that was never ours to open.
What Sets Our Water Leak Detection Apart
Finding a leak properly the first time beats a guess that reopens the same wall twice. That's the whole reason this is its own specialty rather than an afterthought.
Every job runs under proper cover, and 1000+ five-star reviews back that up, plenty from people who'd already had one failed attempt somewhere else before they called us.
Paired Jobs and Surrounding Areas
A slow hidden leak can masquerade as a sluggish blocked drains issue, or get blamed on a hot water repairs fault when it's really a supply line giving way. We'll tell you which one you're actually looking at.
Crows Nest, Waverton and Kirribilli see us for the exact same reason.

Good questions, straight answers
Honest Water Leak Detection FAQs
The questions people ask before booking a leak trace.
Do I get a plain-English rundown before water leak detection work starts?
Yes. We explain what the equipment's telling us, where we think the leak sits, and what finding it involves, before you're asked to approve anything.
Can water leak detection legally be done by anyone but a plumber?
No. Tracing and repairing a water leak is licensed plumbing work in NSW, not a job for a general handyman or a guess with a moisture meter.
Can you fix it on the first visit?
Often, yes, once the leak's actually located. Finding it is usually the harder part; the repair itself is frequently the quicker half of the job.
Am I protected if something goes wrong during water leak detection?
We're licensed and insured for every job we take on, and every repair carries the Lifetime Labour Warranty on top of that cover.
Does older pipework make water leak detection trickier?
Sometimes. Galvanised and clay sections respond differently under a pressure test than modern PVC or copper, so the method gets tailored to whatever's actually in the ground.
Do you handle strata, rentals and commercial water leak detection?
Yes, all three. Strata jobs usually need a body corporate contact, and rentals need the owner or agent looped in before we start.
