Plumber repairing an exposed pipe in a trench

Where Do Hidden Leaks Show Up First?

Pipes rarely fail in the open. The signs turn up somewhere away from the fault, so it pays to know what each one means:

A meter that moves with everything off

The cleanest proof there is a leak; the faster it turns, the bigger the hole.

A warm spot on the floor

Hot water pipes under a slab betray themselves as a warm tile patch long before anything surfaces.

Bubbling paint on one wall

A joint weeping inside a brick-veneer cavity keeps the outside skin wet for weeks before it shows.

A drop in pressure around the house

One pinholed service line feeding every fixture can starve them all at once.

How We Find a Hidden Leak

The trace runs from the outside in, starting with what we can test before anything gets opened:

  1. 01

    Isolate and pressure-test

    We close sections of the water service and watch the gauges. A drop on one side of a valve narrows the fault to a single run.

  2. 02

    Listen with the detector

    Acoustic leak detection gear picks up the hiss of escaping water through soil, slab or brickwork, marking a spot on the ground rather than a wall cavity.

  3. 03

    Trace the pipe's path

    A pipe locator maps the line's route first, so the detector reads along the actual pipe, not a guess at where it runs.

  4. 04

    Open the smallest hole that reaches it

    Only when the fault is marked do we lift a tile, cut one panel or dig one spot, and you see what we found before the repair starts.

What Moves the Price of a Trace?

We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.

The price then depends on:

  • Location At the meter, under the floor or inside a wall each take a different route to reach.
  • What the pipe is made of A copper service, a polyethylene line and old galvanised steel each take different fittings to repair.
  • How deep the line runs Services on benched blocks can travel further under fill than you would expect.
  • The hour we're called A trace after dark or on a weekend is priced at the after-hours rate.

Benched Blocks and the Leaks They Hide

The way this suburb was cut shapes where its pipes fail

Homes here sit on level benches carved into the slope below Munibung Hill, and the fill used to bench them is corrosive to the original copper water services running through it. Half a century in that ground pinholes a pipe from the outside, so an unexplained damp patch on these blocks points first at the copper service.

The soil keeps moving after the pipe stops being new

The clay and shale under these blocks take up water in winter and dry out in summer, easing joints apart one season at a time. A trace done at the first sign of damp is a smaller job than one done after the wall has been wet for a year.

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 shower seeping through its waterproofing

is for a waterproofer or builder to strip and re-seal, though we can pressure-test the pipes in that wall first. Water pooling against the house after rain points to drainage rather than a pipe, and stormwater drains work is the better place to start.

A confirmed leak can also be the first sign of a bigger drainage problem

Where a trace points at cracked joints or root-damaged runs, the CCTV drain inspection footage tells you what's coming next.

Questions Before You Book a Trace

How can I tell there's a leak if nothing is visibly dripping?

Watch the meter with every tap in the house off. If the dial keeps creeping, water is escaping somewhere. Damp patches, a warm tile, bubbling paint or a hiss behind a wall all point the same way, and a trace pins the fault down before any lining comes off.

Can the leak be repaired on the same visit as the trace?

Once the detector and pressure test have narrowed the fault to one section, the repair can follow straight away, and we quote it before touching anything. If the fix needs parts we don't carry on the truck, we cap the leak, quote the repair and come back to finish it.

Is a damp patch at the bottom of a retaining wall a plumbing leak?

Not always. On this hill, runoff from a property above can pool against a wall and look exactly like a burst pipe, so we pressure-test the water service first. If the pipes hold, the damp is drainage, and we point you to the stormwater work instead of selling you a repair you don't need.

Does it cost anything to have you come out and look?

It costs nothing to get us out to your door (excluding after-hours). We locate the leak, explain what we've found and quote the repair before any work starts. Nothing is opened up until you have approved that price.
