How do you know a leak is hiding?
A seep inside a wall or beneath a floor rarely announces itself. By the time staining or pooling shows, the fault has often been running for months. Watch for:
- A water bill creeping up with no change in how you use water
- Damp patches on walls, ceilings or floors that never fully dry
- The meter ticking over while all taps and appliances stay off
- A warm spot on a concrete floor, which points to a hot water line seeping below
- A musty smell in a room that should stay dry
Any one of these earns a look. The longer a hidden fault runs, the bigger the repair behind it, so early tracing keeps the job small.
How We Trace a Leak
The job is methodical, and each step narrows the search.
- 01
Confirm the leak is on your side
We check the meter and isolate sections of the run, so the search starts in the right place and doesn't chase a neighbour's fault or a street-side line.
- 02
Listen for it
Acoustic gear picks up the noise water makes escaping a pressurised pipe, even through concrete or soil, and pins the fault down to a small zone.
- 03
Trace the run
A pipe locator maps where the line actually travels, which matters in older streets where the original routing matches no modern plan.
- 04
Mark and report
You get the fault marked on site, a plain explanation of what is leaking, and the price fixed before any work starts.
Where the seep turns out to be in a drain rather than a supply line, the drain camera takes over: a CCTV drain inspection records the crack or dropped joint behind it.
What Sets the Price of a Leak Repair?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
"[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." Belinda
Location comes first, then the pipe itself:
- Where the fault sits: an exposed joint in a subfloor is quicker to reach than a run hidden behind tiles or under a slab
- What the pipe is made of, since old galvanised and newer plastic lines need different repairs
- How much of the run has to be renewed instead of swapping one fitting
- Whether wall or floor access has to be opened, and how much making good follows
So the number you agree to is the number on the invoice, and you can decide with the whole picture in hand. One customer put it plainly after a leak call:
What the ground does to buried joints. Shale sits under this suburb with reactive clay on top, and every change from wet weather to dry makes the clay heave or settle, working buried joints loose over time. Area-level rainfall averages around 1,128 mm a year, so the ground swings between soaked and dry.
Old galvanised supply lines. Some of the earliest supply runs have never been renewed: cottages around Ida Street and Pearson Street that have skipped renovation still feed off galvanised piping, and a thinned, rusted line is the sort that splits without warning.
Unit fit-outs. Budget flexi hoses and mixers fitted during rapid fit-outs near Charlestown Square can start weeping behind walls within a few years, and strata managers deal with the same fault building after building.
Where a leak is not the only answer. If water is pouring out right now rather than seeping, an emergency plumber is the faster path than a trace, the blocked drains hub covers faults on the wastewater side, and every other job goes to your plumber in Charlestown.
When We're Not the Right Call. A shower that leaks because the membrane under the tiles has failed needs a builder or waterproofer to redo it. A drip that traces back to rusted roof sheets needs a roofer first, so ringing them is the next step, not paying us to guess.
Leak questions from local homes
Can a leak under a concrete slab be found without digging up the floor?
Yes. Listening gear and a pipe locator narrow the fault to a small area first, so any opening we do make is one deliberate cut in the right spot rather than a search across the whole slab.
Are hidden leaks common in the older houses here?
They are a real risk. A lot of the supply piping dates to the postwar building belt, and reactive clay shifting around buried runs is a common cause of slow seeps in homes that have never been repiped.
Will my water bill drop once a hidden leak is fixed?
Usually yes, because a continuous seep pushes water through the meter all day and all night. Once the faulty section is repaired and the run holds pressure, the constant loss stops and usage settles back to normal.
