What Water Leak Detection Covers
A leak you can't see is often worse than one you can, because it keeps running unnoticed while the damage builds underneath.
We're called in when a household notices the dial still moving with every fixture shut off, usage that's crept up with no clear reason, or damp appearing on a wall with no obvious source. Each of those points to a hidden leak in the supply line, and pinpointing it is the whole job.
Rather than digging on a guess, acoustic listening gear, pressure testing and thermal imaging narrow the search before any ground or wall gets disturbed. That's the difference between a targeted fix and a yard full of exploratory holes.
How to Tell This Job Can't Wait
Some signs point to a slow, manageable leak. Others suggest real damage building right now.
The dial that never rests. If it keeps turning with every tap and appliance switched off, water is going somewhere it shouldn't.
A bill that's climbed without explanation. Steadily rising usage with no change in household habits usually points to a slow leak rather than a one-off reading.
Warm flooring or indoor damp. A warm patch underfoot or a stain spreading across a ceiling points to a leak already inside the structure, and that one is worth calling about sooner rather than later.
Why Kellyville Properties Call Us for This
Kellyville's building stock spans decades, from original 1960s and 1970s fibro and brick homes to render-finished builds from the 2000s onward, and each construction style hides its pipework differently.
Older brick-veneer homes typically run supply lines under the slab or through wall cavities that are hard to inspect without the right gear, which is exactly where acoustic detection earns its keep. Newer render-finished homes can mask a leak differently again, since damp can travel some distance before it shows on the surface.
That mix of construction eras is a big part of why we treat every property on its own merits rather than assuming a fixed pipe layout.
What Affects the Price of Water Leak Detection
A few honest factors shape what a leak detection job costs.
- How much area needs to be checked before the source is confirmed
- Whether the leak is under a slab, in a wall, or in the yard
- Pipe material and age, which changes how sound and pressure behave
- Whether a repair is bundled in once the leak is found
On the older render and brick-veneer stock, wall cavities and solid construction can make acoustic tracing take a little longer than on newer, more open-plan builds. Either way, the price for the detection work is fixed and agreed before testing starts, and inspecting the property costs nothing.
The Process, From Quote to Warranty
Your call sends a licensed plumber and the right gear for the water leak detection.
We find the true source behind the water leak detection problem before quoting.
The fixed water leak detection price covers a proper fix, not a patch.
We finish the water leak detection and guarantee the labour for good.
A straightforward detection job is often wrapped up within an hour or two on site. A leak sitting deeper under a slab needs longer to pin down properly, and we won't rush that step just to finish faster.
The Rules That Apply in NSW
Anything on the property side of the meter, from finding a leak to fixing it, is licensed plumbing work under NSW rules. There's no room for guesswork here.
A wrong diagnosis before repair work begins risks opening up the wrong wall or slab entirely, which ends up costing far more than getting it right from the start.
We carry the licence and insurance to do both the detection and the fix, so nothing has to be handed off to a second tradesperson.
The Gear We Actually Use
Acoustic gear tracks the noise a pressurised line makes as it escapes, and it works through most slabs and cavity walls without any digging.
Where that trace isn't conclusive on its own, pressure testing narrows down which section of the line is losing pressure, and thermal imaging can pick up a temperature shift where water is tracking somewhere unexpected. None of it means opening up the property until we're confident of the location.
Why Kellyville Trusts Us With This
Finding a hidden leak comes down to having the right gear on hand, not muscle or guesswork, and that's exactly what turns up with us.
We're also upfront that detection and repair are two separate decisions. You're never locked into a repair just because we found the leak, and the free quote process means there's no cost to knowing where you stand.
Other Plumbing We Sort in Kellyville
A hidden leak often surfaces alongside other ageing-pipe symptoms, which is why we also handle burst and leaking pipes and blocked drains for the same households.
Servicing extends beyond Kellyville too, into Castle Hill and Glenhaven for the same kind of diagnostic work.

Common questions
Water Leak Detection: The Questions People Ask
A few questions Kellyville homeowners raise before booking a leak inspection.
Can you do water leak detection on weekends or after hours?
Yes, weekends and public holidays included, we don't switch off. A spinning meter doesn't respect business hours, so neither do we.
What if water leak detection turns up more than first expected?
We stop, explain exactly what we've found, and give you a revised price before doing anything further. Nothing extra happens without your say-so.
Do you do water leak detection on ageing pipework?
Regularly. Older galvanised and clay-jointed runs behave differently under pressure testing than modern pipe, so we adjust our method rather than applying one approach to every property.
What's your method for water leak detection?
We combine listening equipment, pressure testing and, where needed, thermal imaging to narrow down a location without digging up the whole yard on a guess.
Do I need a licensed plumber for water leak detection?
Yes. Both pinning down where a leak sits and repairing it need a licensed plumber under NSW rules, and a wrong diagnosis just means paying for the job a second time.
How much does water leak detection cost in Kellyville?
The price depends on how straightforward the leak is to locate and access. We always agree that figure with you before any testing begins, so there's nothing to guess at.
