Water Leak Detection, From Assessment to Fix
We bring detection equipment before we bring a shovel. Pinning down exactly where water is escaping avoids opening a wall or slab that has nothing wrong with it.
- Meter and pressure testing: confirming there's a genuine leak before anything else.
- Acoustic and thermal tracing: pinpointing a run under concrete or inside a cavity without cutting first.
- Ceiling and wall staining: working back from a visible mark to where the water actually entered.
- Rising-usage diagnosis: explaining a jump in the bill when nothing on the surface has changed.
- Repair once located: fixing the actual leak, not just noting where it is.
Is It Time to Call a Plumber?
The meter won't stop. Shut off every tap and appliance and watch it for a minute. Any movement at all means water is going somewhere it shouldn't.
Usage has jumped without explanation. No new appliance, no extra people in the house, just a bigger bill.
A patch of lawn stays wet longer than the rest. Or a ceiling shows a stain that grows slowly over weeks rather than appearing all at once.
If you can already see the source, like water actively spreading from a fitting, that's a more urgent situation with its own page: Burst & Leaking Pipes.
Why Merrylands Properties Call Us for This
Cottages from the inter-war years near the railway station commonly still run original galvanised steel supply pipes, and those corrode from the inside over decades. That slow narrowing eventually opens small leaks that show up as reduced pressure or a creeping bill, long before any visible water appears.
Post-war brick-veneer homes spreading out from around Excelsior Street carry a similar story, just a few decades younger. The reactive clay soils under this part of Cumberland add another layer, since ground movement can stress a supply line at a joint that's already weakened by corrosion.
Detecting that kind of leak early, before it becomes a burst, is exactly what this service exists for.
Storm-season overland flow in the Duck Creek catchment adds a different wrinkle. Heavy rain can push groundwater against an already-weeping joint, and what was a slow, barely noticeable seep can suddenly show up as a damp patch that won't dry out between downpours.
Water Leak Detection Pricing, Explained Upfront
Access to the suspected area. A leak under a slab takes more work than one behind a wall we can reach easily.
Method needed. Acoustic detection and thermal imaging aren't the same job or the same time on site.
Detection versus repair. Finding the leak is one step; fixing it is a separate, clearly quoted step.
Age of the pipework. Older galvanised lines like those common in Merrylands' pre-war cottages sometimes need a broader check once one leak point is found.
Given how much of the older stock here still runs galvanised supply pipe, finding one corrosion leak often means checking whether nearby sections show the same wear. You end up deciding on the whole picture, not just the one spot.
Our Water Leak Detection Process, Start to Finish
Call about water leak detection any time. Turning up costs you nothing, no call-out fee.
We assess the water leak detection and explain what it'll take to fix.
The fixed water leak detection price is agreed before we start.
We do the water leak detection and guarantee the workmanship for life.
Straightforward jobs, like confirming a fitting leak, are usually wrapped in the one visit. Tracing something hidden beneath concrete genuinely takes more care to pin down accurately, which we'll flag as soon as we know.
Licensed Work, Done to Standard
Leak detection and any resulting repair both fall under NSW's licensed plumbing work requirements. There's no separate lighter standard for diagnostic work.
Whoever attends carries the same licence and insurance as for any other job on this site, so the person tracing the leak is qualified to fix it too, not just point it out.
That matters more than it might seem. A leak found but reported to the wrong trade, or fixed without the right qualification, can leave a compliance gap that shows up later, whether at sale time or during another repair.
Why Locals Choose Us for Water Leak Detection
Advanced detection technology means walls and slabs stay closed until we know exactly where to look. That saves you the cost and mess of a trial-and-error approach.
You'll know what finding the leak costs and what fixing it costs before agreeing to either, not one combined guess.
Related Jobs and the Areas We Cover
A leak that's found often turns out to need Burst & Leaking Pipes work once located, or in older units, connects back to ageing Hot Water Repairs issues. Blocked or overflowing fixtures sometimes share the same root cause too, in which case our Blocked Drains page picks up the story.
We service this suburb alongside Guildford, Greystanes and Granville on the same basis, all part of the one regular run through Cumberland.

Common questions
Common Water Leak Detection Questions
The questions we get before most leak detection bookings.
Is a water leak detection quote free?
Yes, quotes are free and there's a $0 call-out fee on top. You'll get a fixed price for any detection or repair work before we start, with no charge just for us turning up to look.
Do you hold the right licence for water leak detection?
Yes, our plumbers are licensed and insured under Lic #465156C, which covers diagnostic work like leak detection the same as any repair job. Feel free to look the number up yourself.
How soon can you get to me for water leak detection?
Getting someone out the same day is usually realistic, and a real person picks up whenever you ring, day or night. A spinning meter with every tap off is worth flagging as urgent, and we'll treat it that way.
How do I use the $65 off my first service for water leak detection?
Say the word when you call, and it reduces whatever number we land on for the detection and any repair that follows. Works the same here as it does on any job we do.
Can you do water leak detection on weekends?
Yes, we're on call for water leak detection every day of the week, weekends included. A hidden leak doesn't wait for a weekday, so we don't either.
Do you do water leak detection on ageing pipework?
Regularly. Merrylands has plenty of pre-1940 and 1940s-60s housing still running original galvanised supply pipes, and that's exactly where hidden leaks tend to hide. Older pipework just needs a more careful approach, not a different one.
