What Our Water Leak Detection Job Includes
- A full listen-and-look assessment across likely leak points, not just where the damp patch shows.
- Meter testing with everything in the house turned off, to confirm whether there's an active leak at all.
- Acoustic or moisture-meter tracing to narrow down a hidden leak behind a wall or under a slab.
- Checking irrigation, hot water lines and outdoor taps as possible sources too, not just the obvious ones.
- A plain-English explanation of exactly where the leak is and what fixing it actually involves.
- The repair itself, or a clear referral to the right follow-up job if it's better handled separately.

Signs It's Urgent, Signs It Can Wait
Not every leak needs an emergency call, but some genuinely can't wait for a routine booking.
- Water actively pooling, dripping through a ceiling, or spreading across a floor right now, treat that as urgent.
- The meter still spinning even though every tap in the place is shut.
- A water bill that's crept up for no clear reason, worth booking soon rather than treating as urgent.
- Peeling paint, damp patches or a musty smell that's only shown up in the last few weeks.
- A burst pipe is a different, faster-moving emergency, and that page has the steps to take first.
- A slow drip from a tap is usually a leaking tap repair job, not a hidden-leak trace.
What Moves the Price of Water Leak Detection
Finding a leak properly, rather than guessing at it, is where the real work sits, and that's what actually shapes the price.
- Whether the leak's visible or hidden behind a wall, under a slab, or along a beam.
- How many possible sources need ruling out before we can confirm the actual one.
- Whether specialist listening or tracing equipment is needed, or a simple meter test settles it.
- Access to the suspected area, an open wall cavity versus a finished, tiled one.
$0 Call Out Fee covers that first assessment, and you get fair, upfront pricing, no surprises, once we actually know where the leak is.

The Local Story Behind Water Leak Detection
Lilyfield's building history runs in clear waves: pre-war workers' cottages and semis, a run of 1980s-2000s infill, and apartments still going up near the light rail today. Streets like Carrington Street carry that layering directly, a renovated Federation-era semi can sit metres from a townhouse built decades later.
The catch with the older stock is that heavy renovation often hides the original plumbing behind new tiles and cabinetry, so a leak can travel along a beam or under a slab before it ever shows on the surface.
That's exactly the kind of leak a proper trace finds, and a damp patch alone won't tell you.
Newer builds near the light rail have their own version of the same problem, just with different materials involved, modern fittings can still fail, and a slab leak under a 2000s-era townhouse is no easier to eyeball than one under a Federation semi.

Our Process When You Need Water Leak Detection
- Who answers the phone? A real person, around the clock, ready to help with your water leak detection problem before we've even arrived.
- What happens on arrival? We'll tell you exactly what's wrong and the best way to fix it, honestly and in plain English.
- What will it cost? Fair, upfront pricing, agreed before any work on the water leak detection job begins.
- How do I know it's actually fixed? Quality Workmanship Guaranteed, tested before we leave.
Typical timeframe: most water leak detection visits find the source within the one call-out. A hidden slab or wall leak in an older home can take a little longer to trace properly, and we'll say so upfront.
On the renovated pre-war stock especially, tracing a leak hidden behind new tiling or under a slab genuinely takes longer than one behind an open wall, which is exactly the kind of case the timeframe above is hedged for.

The NSW Rules Around Water Leak Detection
NSW licensing rules cover tracing and fixing a water leak the same as any other plumbing job, and that licence is what lets one visit cover both the diagnosis and the actual repair. Whatever we find, a tap, a pipe or a fitting, gets fixed by someone qualified to do it properly.
If the source turns out to sit outside your property's own supply rather than inside it, we'll explain that plainly rather than leave you guessing about who's responsible for what.
Why Choose Us for Water Leak Detection
300+ five-star reviews reflect customers who wanted an honest answer, not a guess dressed up as one. We're open 24 hours for Same Day Service when a leak needs tracing urgently, and every job is Best Price Guaranteed once we've actually worked out what's going on.
That combination matters more on a diagnostic job than almost any other, because the tracing itself is the hard part, and getting it wrong wastes both your time and the trust the visit's supposed to earn.

Surrounding Areas We Service Too
Once we've traced a leak, the fix might be a straightforward leaking tap repair, or a full burst & leaking pipes job if the pipe's genuinely failed. Either way, water leak detection is the first step that tells us which. Rozelle, Leichhardt, Annandale and Balmain sit within the same coverage, any hour.

Good questions, straight answers
Plain-English Water Leak Detection FAQs
Direct answers, nothing dressed up.
Am I protected if something goes wrong during water leak detection?
Yes. Every plumber on the job is licensed and insured for water and gas, Lic #292427C, and the trace and any resulting repair are covered by Quality Workmanship Guaranteed.
How does pricing work for water leak detection?
It's $0 Call Out Fee for the initial assessment, then a fair, upfront price once we know what's actually involved in tracing and, if needed, fixing the leak. No guesswork, no figure until we've looked.
What usually causes this problem?
A perished washer or fitting, a cracked pipe joint, a slab leak under the floor, or a fault in an outdoor line are the usual suspects. Which one it is changes how we go about finding it.
Does ageing pipework change your approach to tracing a leak?
Somewhat, yes. Galvanised and clay pipework respond differently to pressure testing than modern copper or PVC, so what we're chasing changes depending on what's actually buried underground or tucked inside a wall cavity.
What warranty comes with water leak detection?
The trace itself is about finding the truth, not guessing, and any repair we carry out afterward is backed by Quality Workmanship Guaranteed and our Lifetime Labour Warranty on the labour involved.
How do I prepare before you arrive?
Note which taps and appliances you've already turned off, and whether the meter kept moving with everything shut. If you can, clear access to the meter and any suspect wall or floor area.
