The Warning Signs to Act On
Most hidden leaks give some warning, if you know what to look for.
- Your bill creeping upward while nothing about your household has changed
- The meter needle still crawling forward with every tap and appliance switched off
- Walls, ceilings or carpet that stay damp without a clear reason why
- A cool, soggy patch of lawn or garden bed that holds on through dry weather
- A faint dripping or running sound you can't quite trace, behind a wall or under a floor

Water Leak Detection: What's Included
Tracking down a leak nobody can see means ruling things out systematically, not guessing. Here's what a typical visit involves.
Meter and pressure checks. We isolate the property and watch how the meter behaves, the first step in confirming a leak exists before anything else happens.
Acoustic and thermal tracing. Listening equipment and thermal imaging narrow down a leak's location without opening up walls or floors on a guess.
Slab and underground leaks. Leaks running beneath a concrete slab or lawn need specialised tracing gear rather than digging blind.
A written explanation of what we find. You get a clear picture of where the leak sits and what fixing it involves, before any repair work starts.
Advice on what's worth watching afterwards. On an older property, one leak found often means a second is worth checking for while we're already there.

Water Leak Detection Pricing, Without the Guesswork
We price the trace itself as its own job, separate from whatever repair follows it.
- How accessible the suspected leak area is, wall cavity, slab or yard
- Whether specialised tracing equipment is needed beyond a standard visit
- The size of the property and number of fixtures to isolate and test
- Whether the leak sits on the supply side or a fixture's own plumbing
- Timing, since an urgent after-hours trace costs differently to one booked ahead
We quote the detection work upfront, then quote any repair separately once we know what's actually needed.

Why Normanhurst Properties Need Water Leak Detection
Plenty of homes around Fraser Road and the older pockets of Normanhurst still run supply pipe laid well before copper and modern plastic became standard.
Galvanised steel corrodes from the inside, narrowing the pipe and weakening its walls long before anything looks wrong from outside.
By the time it shows itself above ground, in a damp wall or a bill that's climbed for no reason, the pipe underneath has usually been failing quietly for a while.
Pre-war earthenware drainage carries the same risk in a different way, cracking at the joints as the ground shifts around it over decades.
Finding the actual point of failure early, rather than waiting for it to become a burst pipe at 2am, is the difference detection work makes.
It also spares you the cost of guessing. Opening a wall in the wrong spot on a hunch is expensive, and it's exactly what proper tracing gear is built to avoid.

What the Law Asks of Water Leak Detection
Water leak detection itself isn't licensed work in the way a repair is, but any fix that follows has to be carried out by a licensed plumber in NSW.
That matters, because a leak found isn't a leak fixed. Once we've traced it, the actual repair, whether that's a section of pipe or a fitting, needs the same licensing as any other plumbing job.
We carry that licence on every visit, so there's no handoff to another trade once the source is confirmed.
It also means the repair is covered the same way any other plumbing job is, not treated as a separate, unlicensed patch-up.

How We Work an Urgent Water Leak Detection Job
We answer calm, because you might not be. A licensed plumber talks you through it. No judgement, no panic on our end.
We arrive ready, not rattled. Emergencies are what we're set up for, and it shows from the moment we walk in.
You make a calm decision, not a pressured one. A fixed price, put to you plainly, before any work begins.
We leave it fixed and proven. Tested properly, made safe and tidied, with the drama over for the night.
Most leaks are traced within a single visit, though older galvanised runs near Fraser Road can occasionally need a follow-up once the full extent is clear.

What You Get When We Turn Up
Tracing a hidden leak properly takes patience, not guesswork, and it's what we do on repeat across Normanhurst's older housing stock.
Ring at 3am or 3pm and it's the same voice on the other end, a licensed plumber, never a recorded menu.
Once we've found it and fixed it, that work carries our Lifetime Labour Warranty, plain and simple.

Water Leak Detection FAQs
These are the questions Normanhurst homeowners ask us most about tracing a hidden leak.
Is there a fee just to come and look?
No. Assessing whether there's a leak, and roughly where, costs nothing at the door. You only pay once you've approved the actual detection or repair work.
Does water leak detection fix the cause or just the symptom?
Detection finds the cause. Fixing it is a separate step we'll quote once we know exactly what's failing and where.
If the leak turns out worse than expected, does the price change?
We'll stop and talk you through it before anything extra is done. You approve any change before it's added to the job.
Are you insured for water leak detection work?
Yes. Every plumber we send out is licensed and fully insured, on every job, every time.
Do you do water leak detection after hours and on weekends?
Yes, 24/7, including weekends and public holidays. A licensed plumber answers the phone, not an automated line.
How do I know I need water leak detection?
An unexplained jump in your water bill, a meter that keeps moving with everything off, or damp patches with no obvious cause are the clearest signs. The section above covers the full list.
