Most leaks in this suburb are not discovered by anyone seeing water. They are discovered when a quarterly bill comes in at two or three times what it should be, and nothing about the house looks any different.
The reliable test is the meter, not your eyes. Everything off, watch it for a quarter of an hour, and if it is still turning then water is going somewhere. That costs nothing and it works no matter where the leak is.
The part a lot of people never hear about is what happens afterwards. Sydney Water runs a concealed leak allowance that can reduce a bill inflated by a leak nobody could reasonably have known about. Whether it applies is their decision, not ours.
What we can do is hand you a proper written report: what leaked, where, how we found it, what we did and when. That is the documentation an application needs, and it comes with the job rather than as an extra.


Turn everything off and watch the meter for fifteen minutes. It is free, it takes a quarter of an hour, and it answers the question.
Shut every tap and appliance and watch the meter for fifteen minutes. Movement with nothing running means water is leaving the system.
It costs nothing, needs no equipment, and works regardless of where the leak is or whether anything is visible.
Water follows the fall of a slab or a cavity and emerges wherever it can, which may be nowhere you would ever see.
So the absence of a wet patch proves nothing at all, and the bill is frequently the only symptom the property ever gives you.
It exists to reduce a bill inflated by a leak the customer could not reasonably have known about. A lot of households never find out it is there.
Whether it applies to any particular bill is Sydney Water's decision. We will not promise an outcome, and anyone who does is guessing.
An application needs to show what leaked, where, when it was found and when it was repaired, by someone licensed.
Every leak job we complete comes with that written up plainly, at no extra cost, whether you intend to apply or not.
The alternative to detection is opening up the likely spots and hoping, then making good everything that turned out to be wrong.
Acoustic and pressure work narrows a whole property to a point, so one small repair does what several exploratory ones would have.
Agreed in writing before work starts. These are indicative 2026 ranges. Written findings are included on every leak job, whether or not you plan to take them to Sydney Water.
Isolated and stopped, any hour. We deal with the water before we discuss the price.
Acoustic, pressure and thermal, narrowed to a point rather than an area.
Once located. Access moves this figure considerably more than the pipe does.
Cheap now, and among the most destructive failures in a house when left.
What leaked, where, how found, what was done and when. Written to be read by anyone.

On a burst the water gets stopped before anything else is discussed, including money.

Acoustic, pressure and thermal testing to narrow the whole property down to a single point.

A fixed figure with the licence number on it, agreed before the repair starts.

Pressure tested before anything is closed up, then the findings written out for you to keep or take to Sydney Water.
Shut it off at the meter if you can reach it, then call. We will make it safe first and quote afterwards, not the other way round.

Do the meter test before anything else, because it is free and it settles the question. Turn off every tap and appliance in the house, then watch the water meter for fifteen minutes. If the dial is still moving with nothing running, water is escaping somewhere. A concealed leak under a slab or in a wall can run for months with nothing visible at all, and the bill is very often the only symptom you ever get.
It is worth asking, and a lot of people never do. Sydney Water operates a concealed leak allowance which can reduce a bill inflated by a leak you could not reasonably have known about. Whether it applies in your case is Sydney Water's decision and not ours, so we will not promise an outcome. What we can do is give you a clear written report of what we found, where it was and when it was repaired, which is the kind of documentation any application needs.
What was leaking, where it was, how we located it, what we did to repair it and the date the repair was completed, along with our licence number. It is written to be read by someone who is not a plumber, because the people who need it are Sydney Water, possibly an insurer, and you. Every leak job gets one whether you ask or not, at no extra cost.
Easily. Water follows the fall of a slab, a joist or a wall cavity and comes out wherever it can, which may be metres from the actual failure, or nowhere visible at all. That is exactly why the meter is the reliable test and your eyes are not. A leak that never surfaces still appears on the bill every quarter.
With equipment rather than guesswork. Acoustic gear listens for escaping water through the structure, pressure testing isolates which line has lost integrity, and thermal imaging finds the temperature difference a hot water leak leaves. Between them we narrow it to a point before anything is cut or dug, which is what keeps the repair small and the cost down.
They are among the most common causes of serious water damage in Australian homes and they have a service life of about five to ten years. When one fails it does not drip, it releases mains pressure continuously until someone reaches the meter. If you cannot remember ever replacing the braided hoses under your sink or vanity and the kitchen is over ten years old, that is a cheap job now instead of an expensive one later.
An emergency make-safe is $250 to $500. Leak detection is $300 to $600 depending on how much of the property has to be covered. Repair once located is $400 to $1,200 for most jobs, with access moving that more than the pipe does. A flexible hose replacement is $150 to $350. All of it agreed in writing before we start, and the written findings are included.
Tell us what made you suspect it, whether that is the meter, the bill or a stain. And say if you want the findings written up for a Sydney Water application, so we format it accordingly.
Located with equipment, quoted in writing, and written up properly whether or not you decide to apply for anything.
