Water Leak Detection: What We Actually Do
Older homes on Hornsby's Federation-era streets often still carry original supply pipework, laid decades before anyone thought about leak-detection technology. Newer apartments closer to the station bring a different challenge again, shared walls and slab-on-ground construction where a leak can travel a metre before it ever shows on a ceiling.
We use acoustic listening equipment and pressure testing to find exactly where a pipe has failed, rather than opening up walls on a guess.
Ground and slab leaks. Traced without digging up the whole yard first.
In-wall and in-ceiling leaks. Pinpointed before any plasterboard comes off.
Meter checks. We confirm whether the leak is really on your side of the connection.

The Warning Signs Worth Acting On
A leak you can't see is often the one doing the most damage, quietly.
- Your water meter keeps spinning with every tap in the house turned off
- A water bill that's jumped with no obvious reason
- A damp patch on a wall, ceiling or under flooring that won't dry out
- A hissing sound near a wall or under a slab
- Constantly soft or soggy ground in one part of the yard
A bill that's spiked without a visible leak is one of the clearest reasons to book this rather than wait and watch it climb further.

What We See in Hornsby Homes
Jersey Street and streets built to the same pattern carry a lot of pre-1940 housing, where original supply lines have had eighty-plus years to corrode from the inside.
That corrosion narrows the pipe and roughens the interior, which is often exactly where a pinhole leak eventually opens up. Newer apartment stock along the rail corridor has the opposite problem: modern pipework, but shared risers and wall cavities that hide a leak until a ceiling stain gives it away downstairs.
Both situations need the same starting point, tracing the leak properly before anyone opens a wall.
A leak that's been running quietly for months can also show up as a soft spot in flooring or a musty smell in a room that never used to have one. Neither is dramatic on its own, which is exactly why it often goes unnoticed until the bill forces the question.

What Your Fixed Quote Depends On
The cost here comes down to how hard the leak is to pin down, not how urgent it feels.
- Whether the leak is exposed, under slab, or inside a cavity wall
- How much of the property needs testing to isolate the source
- Access, ground level plumbing versus a multi-storey apartment stack
- Whether the repair is a simple joint or a longer pipe section
$0 call-out applies regardless, and the price we agree covers tracing and repairing unless something genuinely new turns up once we're inside the wall.

Our Water Leak Detection Process, Start to Finish
- Your water leak detection call reaches a licensed, insured local team, Lic #465156C.
- We attend, introduce ourselves, and assess the water leak detection properly.
- You get a fixed upfront quote for the water leak detection before we start.
- We complete the water leak detection to standard and guarantee the labour for life.
Detection alone can often be done in under an hour once we're on site. Tracing a stubborn slab leak, or one hidden deep in a wall cavity, can understandably take longer before we're confident we've found it.
We'd rather take the extra time on site than send you a repair quote based on a hunch, since opening the wrong section of wall costs you more than the extra half hour of testing ever would.

What NSW Requires for This Work
A general handyman can't legally trace and fix a hidden supply leak in NSW; that work sits with a properly licensed plumber, no matter how simple it looks.
Our plumbers cover exactly this kind of diagnostic and repair work. Where a leak sits on the Sydney Water side of the meter rather than yours, we'll tell you plainly rather than quote for work that isn't ours to do.

What Sets Our Work Apart
Leak detection with proper technology means we find the actual source before opening anything, which saves you paying to have a wall cut open on a guess.
The repair that follows carries the same lifetime labour warranty as everything else we do, so finding the leak is never treated as a separate, lesser job to the fix.

Water Leak Detection Across Hornsby and Nearby Areas
We trace hidden leaks just as regularly in Waitara, Normanhurst and Asquith, where the same older pipework and newer apartment mix shows up street to street.
If the leak turns out to be an obvious burst rather than a hidden one, our burst and leaking pipes page covers that more urgent end of the job.

Common questions
Your Water Leak Detection FAQs
Honest answers to what people ask before they book this in.
Is water leak detection something a licensed plumber has to do?
Yes, tracing and repairing a water supply leak is licensed plumbing work in NSW. Our plumbers hold Lic #465156C and handle both the detection and the fix.
Will it be safe to use straight after water leak detection?
Yes. Once we've traced and repaired the leak we check the fix holds under pressure before we leave, so the water's safe to use straight away.
Is water leak detection available in the middle of the night?
A hidden leak rarely announces itself at a convenient hour, so yes, we take these calls overnight too. The equipment and the approach don't change with the time.
Is water leak detection a permanent fix?
The detection itself just finds the leak; repairing the pipe is the permanent part, and that's covered by our lifetime labour warranty.
Will the price change if water leak detection is more involved?
If tracing the leak takes longer than expected, we'll tell you before continuing rather than run the bill up silently. Any extra work gets its own agreed price first.
How do I use the $65 off for water leak detection?
Flag it at the start of the call and it's deducted before you pay, whether the job ends up being detection alone or detection plus the repair.
