Water Leak Detection, From Assessment to Fix
A leak you can't see is still doing damage, whether that's a rising water bill, a damp patch that won't dry out, or mould creeping along a skirting board.
- Electronic listening equipment to pinpoint a pressurised pipe leak
- Thermal imaging to spot damp behind a wall or under a slab
- Meter testing to confirm whether a leak is active right now
- Dye testing for a suspected shower or wet-area leak
- A written explanation of the source once it's confirmed
When This Problem Can't Wait
A hidden leak rarely announces itself loudly, but a few signs are worth acting on quickly.
- A bill that's noticeably higher with no change in use
- A meter that keeps spinning with every tap in the house off
- A damp patch, bubbling paint or a musty smell indoors
- A warm patch on the floor, which usually means a hot water line
- Water pooling somewhere with no obvious source
What We See in Mount Colah Homes
Brick-veneer and fibro construction from the postwar decades dominates around Ku-ring-gai Chase Road, and both hide a slow leak well.
A leak behind fibro sheeting can travel a surprising distance before it shows as a stain, and a cavity behind brick veneer can mask a dripping pipe until real damage is done. That's exactly the situation proper equipment is built for, rather than guessing from a mark on the ceiling.
Older homes on these streets also tend to run original copper or galvanised supply lines, which corrode from the inside and leak at a joint long before anything's visible from outside the wall.
That's the pattern we're called out for most on this ridge: a homeowner notices a rising bill or a faint musty smell months after the leak actually started, by which point tracking the exact point of failure properly saves a lot of unnecessary demolition.
Water Leak Detection Pricing, Explained Upfront
Tracing a leak is priced as its own job, separate from whatever repair follows once we know the cause.
That separation matters because a lot of leak-detection outfits blur the two, so the trace turns into an unexpectedly large invoice once they're already on site and you feel stuck agreeing to it.
- How accessible the suspected area is
- Whether it's a simple pressure test or a full trace
- Slab leaks generally take longer to pinpoint than wall or ceiling leaks
- Any follow-up repair is quoted separately once the cause is confirmed
You'll always see the cost before we start tracing, and the $0 call-out fee applies regardless of what we find.
Our Water Leak Detection Process, Start to Finish
Step one, you call and we take down the water leak detection details.
Step two, a licensed plumber assesses the water leak detection in person.
Step three, you get a fixed water leak detection quote and decide.
Step four, we complete the water leak detection and back it for life.
On a fibro or brick-veneer home like most of this suburb's older stock, that assessment usually starts with thermal imaging before anything gets opened up.
Guessing where to cut into solid brick veneer wastes time and money for everyone. Most detection visits finish within the one appointment; a genuine slab leak occasionally needs a second visit with different equipment.
Done Right, and Done to Code
Locating a leak doesn't require a licence in itself, but NSW law puts whatever repair follows, cutting into a water line or a gas line, in the hands of a licensed plumber.
We handle both stages ourselves, so there's no gap between finding the problem and being allowed to fix it.
If your leak happens to involve a gas line rather than water, that switches to our gas fitters specifically; NSW treats gas work as its own licence category, separate again from general plumbing.
What Sets Our Work Apart
We invest in the equipment that finds the actual leak, not just where the water happens to be pooling by the time you notice it.
Free quotes and honest pricing with no surprises mean tracing a leak never turns into an open-ended bill.
That matters most on a job like this, where a homeowner has no way to check our working themselves; we show you what the equipment found rather than asking you to take our word for it.

A confirmed leak sometimes turns out to be a burst fitting rather than a slow weep, in which case burst & leaking pipes takes over from there. A leak that's actually overflow from a blocked line points back to blocked drains instead.
We cover Hornsby and Waitara on the same basis, tracing leaks across Mount Colah and the wider Hornsby Shire.

Common questions
Questions We Get About Water Leak Detection
A few things Mount Colah homeowners ask before booking a leak trace.
Do I need a licensed plumber for water leak detection?
Not for tracing the leak itself, but fixing what we find does need a fully licensed plumber, which NSW requires. One visit covers both parts of the job.
Is the water leak detection quote fixed before work begins?
Yes. We quote the detection work upfront, and if a repair follows, that's quoted separately once we know exactly what we're dealing with.
Is water leak detection a true emergency?
A slow, contained leak can usually wait a day or two for a booking. A leak near electrics, or one that's rapidly worsening, is worth calling about straight away.
Will you tell me why water leak detection was needed?
Always. We'll show you what we found, whether that's a meter reading, a thermal image or the physical damage, before explaining the fix.
Will water leak detection fix the problem for good?
Once we've traced the actual source and repaired it properly, yes. Patching a symptom without finding the cause is how the same leak comes back.
Who is responsible if the problem is in the public main?
If it turns out to be the public main rather than your private line, that's the water authority's responsibility, and we'll tell you plainly if that's what we find.
