Signs It's Time to Pick Up the Phone
- Your latest bill jumping for no reason you can point to
- The meter ticking over even though nothing inside is running
- A damp patch on a wall, ceiling or carpet that keeps coming back
- A musty smell without a visible source
- A wet patch in the yard that isn't from rain or the garden

What We Handle Under Water Leak Detection
Leak detection covers the finding, not just the guessing. Here's what that looks like in practice.
Hidden slab and wall leaks
Water moving under a slab or inside a wall cavity, traced with proper equipment rather than opened up blind.
Meter and pressure checks
Isolating whether the leak sits inside the house or on the supply line itself.
Damp and mould source tracing
Following moisture back to where it's actually entering, not just where it's showing.
Post-detection repair
Tracing it properly first means the fix that follows is quoted and carried out as its own job.
How We Price Water Leak Detection
- Whether the suspected spot is easy to reach or buried deep
- Slab, wall cavity or yard, each needs a different approach
- Whether it's a single fitting or a longer run of pipe
- Any make-safe work needed on the day
- The repair itself, priced separately once we know exactly what we're fixing
We never guess and hope. Detection is quoted as its own step, and the repair that follows gets its own fixed price too, so you're never paying to find out and paying again to fix it as one blurred number.

What We See in Cherrybrook Homes
Cherrybrook's housing is overwhelmingly brick veneer over a timber frame, with a smaller share finished in solid brick or render, built out mostly since the 1980s.
That construction style means water from a hidden leak tends to travel sideways along the wall cavity before it ever shows on the surface. By the time a stain appears near Castle Hill Road, the actual source can sit metres away.
Render finishes can hide the problem longer still, since damp doesn't always show through a painted or rendered surface the way it would on bare brick.

Standards and Safety, Explained Simply
Plumbing work in NSW, including tracing and repairing a leak, has to be carried out by a licensed tradesperson, and our plumbers hold that licence and full insurance.
Where a leak turns out to involve gas piping rather than water, that work shifts to our licensed gas fitters under the same ticket. Either way, nothing gets opened up without you knowing what we're doing and why.

Our Water Leak Detection Process, Start to Finish
- 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.
On a straightforward fitting, tracing the source often takes an hour or two once we're on site. A leak buried under a slab can take a full visit to confirm properly, and we'd rather take that time than guess.

Why This Is a Job for Our Team
We're a family-run team that's been working across Sydney for over ten years, and leak detection is one of the jobs where that experience actually shows, knowing what a spinning meter usually means before we even arrive.
There's a $0 call-out fee whether the leak turns out to be minor or major, so getting someone to look never costs you anything extra.

Servicing Cherrybrook and the Suburbs Around It
We trace and fix hidden leaks across Thornleigh, Westleigh and Castle Hill too.
Already watching water actively flood the place? Head to burst and leaking pipes instead.

Common questions
Water Leak Detection: The Questions People Ask
How quickly can you come out for water leak detection?
Usually the same day, particularly if you're staring at a bill you can't explain. Give us a call and we'll send someone to investigate properly.
When should I call about water leak detection?
A rising water bill with no obvious cause, a meter that spins with every tap off, or a damp patch that won't dry out are all good reasons to call. Waiting usually just lets the damage spread further.
Do you hold the right licence for water leak detection?
Yes, our plumbers are fully licensed and insured, #465156C, and leak detection work sits within that licence just like any other plumbing job we do.
Is the water leak detection quote fixed before work begins?
Yes. We quote the detection work itself upfront, and once we've found the source, you get a separate fixed price for the repair before we touch anything.
Could the problem come back after water leak detection?
Not if we've traced the actual source properly. That's the whole point of proper detection over guesswork, chasing the real leak rather than patching the spot where water happens to be showing.
Can you explain what caused the problem behind water leak detection?
Always. Once we've traced it, we'll show you what caused it, whether that's a fitting, a joint, or pressure somewhere in the line, so you understand the fix.
