How to Tell This Job Can't Wait
Some water loss is obvious. Plenty isn't, and that's exactly the kind that costs the most before anyone notices.
- Your water bill's climbed with no change in how you use it
- The meter keeps spinning even with every tap off
- A damp patch on a wall, ceiling or floor with no clear source
- A musty smell that won't shift, especially near a slab
- Warm patches on the floor that suggest a hot water line underneath
What's Involved in Water Leak Detection
We use acoustic listening equipment and thermal imaging to find a leak without cutting into walls or floors on spec.
Guesswork is expensive to undo. A wall opened in the wrong spot still needs patching and repainting even after the real leak's found somewhere else, so narrowing it down properly first saves both time and mess.
- Checking the meter against actual usage to confirm a leak exists
- Acoustic listening along pipe runs to narrow down the location
- Thermal imaging where a slab or wall leak is suspected
- Pressure testing to isolate which section of pipe is affected
- A clear picture of exactly where the leak is before any repair starts
Water Leak Detection Pricing, Explained Upfront
The property and the leak's location drive the price, not the day of the week.
- How accessible the suspected area is, wall cavity, slab or yard
- Whether one leak is suspected or several
- Whether detection alone is needed or a repair follows straight after
- Any make-good work once a wall or slab has been opened
You'll get that figure set out clearly before we start locating anything, so there's nothing to work out afterwards.
What We See in Normanhurst Homes
The ground under Fraser Road and the streets around it is shale and sandstone, sitting up on the Hornsby Plateau at close to 170 metres. That's solid, stable ground, which is actually part of the problem.
A leak here doesn't show up as a wet patch spreading across soft soil the way it might elsewhere. Water tends to track along the rock and resurface somewhere well away from the actual pipe, which is why a hunch and a shovel gets it wrong so often.
Add in the original galvanised supply lines still common in houses from this era, and a slow pinhole leak inside a wall can run for months on a shale-based block before the water bill finally gives it away.
What NSW Requires for This Work
Locating a leak is diagnostic work, but any repair that follows, cutting into a wall or replacing a section of pipe, is licensed-plumber territory under NSW rules, no way around it.
Should the source sit on the supply side before your meter, that's generally the water authority's responsibility rather than yours, not something we'd invoice you for.
We hold the licence for both the detection work and whatever repair comes after, so there's no handover between trades.
That matters more than it sounds.
A separate diagnostic firm can find the leak and walk away, leaving you to source a plumber to actually fix it. We handle both under the one visit.
How We Work Through Water Leak Detection
- From your first call about water leak detection, we plan to leave your home as we found it.
- We set up cleanly and assess the water leak detection with the area protected.
- You approve a fixed water leak detection quote before work begins.
- We finish the water leak detection, clear away, and back the job for life.
On the shale blocks common around here, sound carries further than usual through the rock, which actually helps our acoustic gear narrow things down. One visit is usually enough to pin the source down, though a hard-to-reach slab leak can need a return trip to open up and repair properly.
Why Normanhurst Trusts Us With This
Finding a leak without guessing takes the right gear and the patience to use it properly, not just a moisture meter and an assumption.
We're licensed plumbers and gas fitters, so a gas-related fault gets picked up in the same visit, not referred elsewhere.
Any repair we carry out afterwards is backed by a lifetime labour warranty, the same as every other job we do.
Servicing Nearby Homes Too
A hidden leak sometimes explains a problem that looks like something else, low pressure at a leaking tap, or a damp patch mistaken for a blocked drain. We check the whole picture, not just the symptom you called about.
We cover Normanhurst out to Hornsby, Wahroonga and Thornleigh on the same basis.
The same shale-ridge geology runs right through this pocket of the Hornsby Plateau, so the detection approach that works on Fraser Road works just as well a few streets over.

Common questions
Water Leak Detection FAQs
The questions that come up most with this particular job. Nothing here covering it? (02) 9054 3067 will.
Are you available for water leak detection out of hours?
Yes, we're on call every hour of the day. A hidden leak doesn't keep business hours, so neither do we.
What if the issue is on Sydney Water's side?
If it turns out to be on the utility's side of the meter, that's outside what we can fix, and we'll point you toward Sydney Water directly.
Could the cost rise if the leak proves harder to pin down?
Only if the leak turns out to be in a harder spot than expected, and we'll always quote that extra work before going ahead with it.
Can water leak detection wait until morning?
A small, steady leak usually can. A meter spinning fast with everything off, or water tracking toward a wall cavity, is worth calling about straight away.
How long does water leak detection usually take?
Most leaks are located within a single visit. A harder case, especially in solid rock or under a slab, can occasionally need a second visit to pin down.
How do I know water leak detection is needed?
A rising bill with no change in usage, a meter that keeps moving with taps off, or damp appearing with no obvious cause are the usual signs.
