Water off fast, the leak located before anything is opened up, and a fixed price agreed first. On sandstone, finding it precisely is worth far more than it is anywhere west.

Three separate stories, depending on which building you are standing in.
In the century-old housing through Chatswood West and the conservation pockets, the pipework has been added to for generations. Original cast iron waste corroding through, post-war copper developing pinholes, and lead-jointed connections that were never meant to last this long. None of it fails dramatically. It seeps, stains, and drifts your water bill upward until somebody investigates.
In the apartments, the failure is almost always a fitting or a membrane rather than a pipe. A braided flexi hose under a vanity has a service life of about a decade and lets go at full mains pressure. A shower waterproofing membrane fails slowly and shows up as a stain on the ceiling below. The second one is the reason so many leaks here become a dispute: the damage is in one apartment and the fault is in another.
Underneath both is sandstone. It means the ground is stable, so you do not get the joint movement that plagues the western suburbs. It also means that when a leak is genuinely underground, reaching it is rock work. Locating precisely is not a nicety here, it is the difference between opening one spot and hiring a breaker.
Call and we will talk you through the isolation valve or the meter while the van is moving. In a unit, knowing where your own stop tap is saves the ceiling.
Water does not fall straight down through a building. It travels along a slab, follows a penetration, drops, and can repeat that below.
So the apartment reporting the damage is usually not the apartment the leak is in, and it can skip a floor entirely.
That is worth establishing before anybody starts allocating blame, because the instinct is to assume it began where it appeared.
Original cast iron waste corrodes from the inside and eventually perforates rather than splitting. Early copper thins and weeps at a point.
Neither announces itself, so the first symptom is frequently a stain or a bill long after the loss began.
Which is why the meter test matters more on older housing here than on anything modern.
The rock here is often within a metre or two of the surface and has to be broken rather than dug, so every hole is expensive and every extra hole more so.
That changes the economics of detection completely. Opening the likely spot and hoping is a considerably worse bet here than on soil.
So locating precisely is not a premium service on this ground. It is what keeps the job affordable.
Shut every tap and appliance and watch the meter for a quarter of an hour. Movement with nothing running means water is genuinely leaving on your side.
In an apartment, check whether your lot is separately metered before relying on the result, because in older buildings the whole block is frequently on one.
Turn any irrigation off entirely rather than to a rest day.
That is what the second reading answers. Close the hot water unit's inlet valve, change nothing else, and watch the dial again.
Movement continuing points at the cold side. Movement stopping points at the unit or the hot line running from it.
A relief valve discharging continuously produces a hot-side result with nothing actually wrong inside the tank, so check that outlet first.
Acoustic listening, thermal imaging and pressure isolation narrow a leak without touching the building, and all three work through a slab.
Opening a ceiling in somebody else's apartment is disruptive, expensive and quite often reveals nothing but wet plaster.
The cost of locating properly is almost always less than the cost of opening the wrong ceiling once.
Braided flexi hoses sit under almost every vanity and behind most cisterns, at full mains pressure, in cupboards nobody opens, and they last about five years.
They fail all at once, frequently while an apartment is empty, and in a block one failure reaches every home below it.
They are inexpensive and quick to replace, and doing a whole building at once is a genuinely sensible collective decision.
A leak between lots involves two insurers, an owners corporation and frequently two residents who have never spoken.
So the written finding matters more than usual: what failed, where, whether it is lot or common property pipework, and what it needs.
That document is what everybody else acts on, and it cannot be produced afterwards from memory.
Whoever assesses this later was not there, and afterwards it is a dry patch and a description.
Take the source if visible, the extent of the water, the affected surfaces and something showing the time.
In a building with several parties involved, half a minute of photographs is unusually valuable.
Closing your apartment's stop tap needs nobody's permission and it is the single thing that decides how much damage there is.
Find it now rather than then. In these buildings it is usually in a cupboard, a laundry or behind an access panel.
Then tell the apartments below, then photograph, then make the call.
That water is escaping somewhere, and nothing more precise than that. It does not indicate distance, direction or which pipe.
Water follows structure, and structure carries it a long way before it finds a way through, particularly downward on a sloping or multi-level house.
So the correct response to finding one is to locate rather than to open, because opening it reveals wet material far more often than a fault.
Sydney Water operates an allowance that can reduce a bill inflated by a leak the customer could not reasonably have known about. The eligibility rules are theirs and worth reading in their own material.
An application is supported by evidence rather than by an account: the date the loss was identified, what was found, and the repair by a licensed person.
None of that can be assembled after the fact, which is why the written finding is produced at the time and handed over.
Where a fault sits on an external run over shallow sandstone, the excavation is broken rather than dug, and the cost is set by depth and hardness rather than by the length of pipe.
So two identical repairs on the same street can differ substantially, and neither figure is wrong.
It is worth asking any quote what it assumes about the ground, because that assumption is where the variation comes from.
Once a fault is located, going around an obstacle can genuinely cost less than reaching it. A new line in the correct material, properly installed, is not a compromise repair.
On shallow rock that comparison comes up more often here than in most suburbs, and it is worth asking for as an alternative quote.
It also frequently leaves you with a run that is accessible in future rather than one buried under stone.

In a house that is the meter. In a unit it is your isolation valve, or the building riser. We talk you through whichever applies before anything else.
Water off and the escape contained before any diagnosis starts. Nothing gets quoted while it is still moving.
Acoustic along the line, thermal where hot water is in play. On sandstone the whole point is opening one spot instead of breaking rock to look.
Fixed figure approved first. What failed and where goes into writing with photographs, which is what strata and the insurer will both ask for.
Turn your own water off, then call. If it is coming from the apartment above, we can establish that without anyone opening a ceiling.
Call 1300 381 569Turn the water off. In a house that is the meter at the front boundary, clockwise until it stops. In an apartment it is usually an isolation valve inside your lot, often in the laundry or under the sink, and if you cannot find it the building manager can shut the riser. If water is anywhere near a light fitting or the switchboard, kill the power first. Then open the lowest tap you have to drain the pressure out of the pipework rather than into a ceiling.
Almost never directly above it, and in a unit block usually not even in your apartment. Water runs along the top of a ceiling sheet, along a joist or down a service duct until it finds somewhere to drop, so the visible stain can be metres from the source and a floor up. In practice a ceiling leak in a flat is most often a failed shower waterproofing membrane or a flexi hose in the apartment above. That makes it a common property or upstairs-lot question, not automatically yours.
It turns on where the failure is. A flexi hose or a waste pipe inside the upstairs lot is generally that owner's. Waterproofing membranes and the common pipework in the slab or the risers are generally the owners corporation's. The reason people end up arguing is that nobody has established which it is. Thermal imaging and a moisture meter answer it without opening anything, and we put the finding in writing for the strata manager.
There was usually warning. In the older houses here the common story is copper from the post-war decades developing pinholes, or original cast iron waste corroding through, and the early signs are falling pressure, a stain that comes and goes, or a water bill drifting up. In anything built or renovated in the last fifteen years it is more often a braided flexi hose reaching the end of its ten-year service life, and those give no warning at all.
That is the whole point of doing it properly, and it matters more here than most places. Chatswood sits on sandstone that is often within a metre or two of the surface, so an exploratory trench is not a shovel job, it is rock work. We use acoustic listening along the line and thermal imaging where hot water is involved, so we open one spot rather than search. On this ground that is frequently the difference between a repair and a project.
Turn every tap and appliance off and watch the meter. If the dial is still moving, water is going somewhere it should not, and that takes ten minutes to establish. In an apartment check your own isolation valve first, because a running toilet cistern is the most common and least dramatic answer. Sydney Water has a concealed leak allowance in some circumstances and it needs the repair documented, so keep the paperwork.
Usually the damage is and the pipe itself usually is not. Most policies cover water damage to the building and contents from a sudden burst, exclude the cost of repairing the failed pipe, and exclude damage from a leak that has been seeping gradually rather than bursting. In strata there are two policies in play, the building policy and your contents, and which responds depends on the same question as above: where the failure was. We document it with photographs because that is what both insurers will ask for.
Tell us whether it is a house or an apartment and where the water is showing. In a building, where it shows and where it comes from are usually two different places.
Fixed price agreed before the repair starts, and the finding documented for strata and your insurer.
