How to Know It's Time for Water Leak Detection
Not every leak announces itself with a puddle. These point to water moving where it shouldn't, even out of sight:
- The meter dial still creeping along with every tap firmly shut
- A bill noticeably higher than usual with nothing to explain it
- Walls, ceilings or skirting feeling damp without an obvious cause
- A musty smell that lingers with no clear source
- One patch of flooring feeling warm, often a sign near a hot water line
- Water noise somewhere in the house when every fixture is switched off

Water Leak Detection: What's Included
Finding a hidden leak isn't guesswork with the right gear. Here's what a typical visit includes, from first check to final confirmation:
- Checking the water meter for movement with everything switched off
- Listening and using acoustic gear to narrow down a likely area
- Checking damp walls, ceilings and flooring for moisture patterns
- Isolating sections of pipework to narrow the search further
- Narrowing the search down to a specific spot before anything gets opened up
- A plain-English rundown of the findings and the options for fixing it
Fair, Upfront Pricing on Water Leak Detection
What a visit costs comes down to how well hidden the leak turns out to be, not a flat call-out figure. Here's what typically influences it:
- How accessible the suspected area is, whether wall, slab or ceiling
- Whether one leak is suspected or several
- The type of pipework involved
- How much tracing time the job genuinely needs
Older galvanised lines, common in Kensington's pre-war homes near Carlton Street, corrode from the inside and can take a little longer to trace than newer copper or PEX pipework, which we factor into the price.
There's no call-out fee, and we put a fair price in front of you before any wall or ceiling gets opened, backed by our Best Price Guaranteed.

Water Leak Detection on Kensington's Streets
Kensington's pre-war homes, especially around Carlton Street, commonly still run galvanised steel supply pipes rather than modern copper or PEX.
These pipes corrode from the inside over decades, which narrows the flow and eventually lets water escape through a pinhole rather than a dramatic burst.
That's exactly the kind of leak that's easy to miss until a bill jumps or a wall feels damp, which is why detection matters more in these older properties.
Newer sections of Kensington, built with different pipe materials, see fewer of these slow, hidden leaks, but they're not immune to a fitting or joint failing.

Who's Responsible for What on Water Leak Detection
Diagnosing and repairing a leak inside your property is plumbing work under NSW law, carried out by a licensed plumber.
Water and gas both sit under our licence, so a leak that turns out to involve a gas line doesn't mean calling anyone else out.
Should tracing point to a fault beyond your boundary, on the street side, that falls to a different authority, and we'll say so plainly.

Our Callout Process for Water Leak Detection
- First: get the water off at the meter, if you can reach it safely. We'll talk you through this on the call before we've even left.
- We arrive and isolate the problem properly, working the water leak detection issue back to its actual source, not just the visible leak.
- We'll tell you exactly what's wrong and the best way to fix it, then fair, upfront pricing before any work starts.
- Repaired, pressure-tested and cleaned up. Quality Workmanship Guaranteed on every water leak detection repair.
Tracing a leak typically takes most of a visit, often one to two hours, though concealed leaks under a slab can occasionally take longer to pinpoint accurately.
What You Get When We Turn Up for Water Leak Detection
A hidden leak is unsettling precisely because you can't see what's actually happening. We'll tell you exactly what's wrong and the best way to fix it, in plain terms, once we've found it.
Licensed and insured for water and gas, Lic #292427C, so wherever the leak has travelled, the right trade is already on-site.
And should a repaired leak ever reopen, the Lifetime Labour Warranty brings us straight back to put it right, at no cost to you the second time.

Servicing Homes Beyond Kensington
A leak isn't always where it seems, and sometimes it's actually a burst & leaking pipes situation rather than a slow hidden one. If a drain backs up alongside a damp patch, our blocked drains page might be the better fit.
We also service Maroubra and Randwick, and the suburbs around them.

Good questions, straight answers
Straight-Answer Water Leak Detection FAQs
The questions we hear most from Kensington homes about tracing a hidden leak.
What's usually behind Water Leak Detection jobs like this?
Ageing galvanised pipework is a common cause in Kensington's older homes, corroding from the inside until a pinhole leak forms. In newer properties, it's more often a failed fitting, seal or joint under pressure.
Does the price change if you discover extra faults during Water Leak Detection?
It can, but never without telling you first. Turning up a second issue means a fresh conversation and a new number to approve before we go any further.
What state is my home left in after Water Leak Detection?
We leave the work area clean and any access points, like a small section of wall or ceiling, tidied up as much as the repair allows. Anything beyond that, like patching plaster, we'll discuss with you.
Do you offer $65 off my first service?
Yes, first-time customers get $65 taken off, and it applies to leak tracing the same way it applies to any other job we do.
Do you charge a call-out fee for Water Leak Detection?
No. The call-out is $0, so having us come out and properly investigate a suspected leak costs you nothing upfront.
Do your vans carry the parts for Water Leak Detection?
Yes, our vans carry common fittings, valves and seals, so once a leak is found, we can often fix it there and then instead of booking a second trip.
