What Points to a Hidden Leak?
- The meter dial creeps along with the whole house shut off
- The bill rises from one quarter to the next without a change in routine
- A ceiling stain spreads after a shower upstairs, or grout keeps darkening at one spot
- Skirting boards soften or paint bubbles at the base of a wet-area wall
- One strip of lawn stays green and soft through a dry month
- The water heater cycles more than it used to, which can mean a hot line losing water

What Sets the Price of a Leak Trace?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
How long the search takes depends on:
- What covers the line As a slab, tiled floor or paved alfresco is slower to read than a garden bed
- The size of the property Because a large block has more line to rule out
- How many leaks there are Since a failing batch of fittings can mean more than one
- Whether a pressure test is needed To separate two runs that share a trench

A burst hose spraying under a sink is an emergency, not a trace, and the emergency plumber page covers what to do.
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
Damp creeping out from a shower base while the pressure test holds steady points to a broken seal beneath the tiling, not a pipe. Stripping and resealing that area belongs to a waterproofing contractor or builder. A smell of gas rather than a wet patch goes straight to our gas leak page.
Leak Questions Before You Book
My water bill jumped. Is that enough reason to book?
It is a good first clue. Read the meter at night after the last tap is used and again before anyone gets up. If the numbers differ, water is leaving the pipes somewhere, and a trace will tell you where before the next bill arrives.
Can a leak be under the slab of a newer house?
Yes. Estate homes here run their water lines through or under the slab, and a joint that shifts with the clay can weep there for months. Warm tiles, lifting floorboards or a damp patch at a wall base are the clues, and the listening gear works through concrete.
Why does the damp patch not line up with the leak?
Water follows the pipe, the framing or the fall of the slab before it shows, so a stain can appear a long way from the fault. Tracing the pressurised pipe finds the source; digging under the stain alone risks opening the floor in the wrong place.
What happens after the leak is marked?
The repair is priced as one set figure, whether it is a single fitting behind a vanity or a new length of buried line, and the choice to go ahead. A small fitting can be replaced there and then. Every repair carries our 365-day warranty on all work.
