How Do You Know a Leak Is Hiding?
These signs point at a pipe losing water somewhere you cannot see:
- The meter dial still turning with all the taps off
- Bubbling paint or a tide mark on plaster where no tap or roof sits above
- The hot tank running cold sooner than usual, which can mean it is leaking into its drip tray or under the floor
- One strip of lawn that stays lush and spongy in dry weather, or a warm spot under the floorboards
- An unexplained jump in the water bill with no change in how the house is used
If you notice one, a detector check is the next step. It costs nothing to get us out to your door (excluding after-hours).

What Moves the Price of a Leak Trace?
A leak trace is priced on how hard the pipe is to hear and reach:
- Depth and cover, since a buried run beneath a slab is slower to pin down than one behind plasterboard
- Pipe material, as copper thinned by salt air and ageing galvanised steel carry sound differently to newer polyethylene
- The length of pipe between the water meter and the suspected leak, since a longer run takes longer to listen along
- Whether the repair is a single joint swap or a section of pipe that has to be replaced

What Customers Say
[The team] came to our home to inspect a water leak yesterday. … They were able to identify and service the leak and were happy to talk us through the process.
When We're Not the Right Call
A smell of gas is not a water leak; it belongs with gas leak detection, and a heavy odour means ringing the gas network's emergency line before us. Water coming back up a floor waste is a blockage, which is drains work rather than a trace.
Leak Questions We Hear
How do you find a leak without tearing up the floor?
The detector listens for escaping water through the surface, and the locator shows where the pipe actually runs. Together they narrow the leak to a small patch of floor or wall, so any cutting is measured in centimetres, not rooms.
Why does a high water table make leaks harder to spot in Belmont?
Groundwater keeps the sand moist near the surface here, so a leaking pipe does not always show as an obvious wet patch. Damp that never dries between downpours, or green patches that outgrow the rest of the lawn, are worth a detector pass rather than a guess.
Is a hidden leak worth chasing if it is small?
A slow drip never stops, so even a pinhole adds up on the water bill over a quarter. On older copper runs corroded by salt air, a first pinhole is usually a warning that the pipe wall is thinning, and catching it early avoids the flood version of the same fault.
Do you trace leaks outside Belmont as well?
Yes. The same leak detection run covers Belmont North, Redhead, Belmont South and Valentine, each of which has its own page, and the same fixed quote and 365-day warranty on all work applies wherever the job sits.
Book the Trace
A burst flexi hose flooding a vanity is an emergency call; a slow hidden leak is a booking, and either way the trace comes first. If a camera look at the pipes behind the damp would help, our CCTV drain inspection service films the line so the repair talk starts from footage.
