Servicing Perth's southern suburbs
Located without the guesswork
A hidden water leak is a slow bleed. It might be a pipe under the slab, a line inside the wall or a connection behind the shower. Left unfound, it rots the structure, drives mould and sends your water bill climbing every single month.
At Frecks Plumbing & Gas, Ben uses his own ultrasonic leak detection equipment and pipe locators to pinpoint the leak before any digging or cutting starts. You find out exactly where it is and exactly what it will take to fix it.
Ben handles the whole job from first call to clean-up, and where a leak is on a buried line he can dig it up and repair it himself with his mini excavator, so it all stays with one tradie and there are no surprises on the invoice.
What we find and fix
- Burst and hidden pipes inside walls and ceilings
- Slab leaks under concrete floors
- Under-floor leaks in suspended and timber-floor homes
- Wall and ceiling leaks from deteriorated or damaged lines
- Water-bill-spike investigations
- Meter-ticking checks to confirm a leak is present
Signs you have a hidden leak
- Your water bill jumped but your usage has not changed
- The water meter keeps ticking over with every tap turned off
- Damp patches, bubbling paint or mould appearing on walls or ceilings
- Warm or hot spots on the floor slab (often a hot water line leaking below)
- The sound of running water when nothing is on
- Unexplained drop in water pressure at taps or the shower
How we track down hidden leaks in Perth homes

You call and describe what you are seeing
Tell us what raised the alarm, a bill spike, a damp patch, a sound you cannot explain. We will ask the right questions so we arrive prepared.
We confirm a leak is present
A meter check with all outlets closed takes about two minutes and tells us definitively whether water is going somewhere it should not.

We locate it without unnecessary damage
Ultrasonic leak detection and pipe locators let us narrow the leak to a specific spot so we open up only what needs opening, not half the wall or the whole slab.
We fix it and show you what caused it
Once located, we repair the line, pressure-test the fix, and walk you through what let go so you understand what happened and why.
Where hidden leaks come from in Perth homes
Corroded copper and galvanised pipe
Older Perth homes often still have original copper or galvanised steel lines. Corrosion eats through the wall of the pipe over years, producing pinhole leaks that hide inside walls for months.
Ground movement and soil shift
Perth's sandy soils move more than people expect. That movement puts stress on buried and slab-encased lines until a joint cracks or the pipe splits.
Poor or deteriorated pipe joints
A joint that was under-tightened, fitted with the wrong fitting or has simply hardened with age will eventually weep. These show up as slow, persistent leaks rather than a sudden burst.
Tree root intrusion
Roots chase moisture into hairline cracks in buried water lines. What starts as a tiny weep grows into a broken pipe as the root expands season after season.
High water pressure
Perth reticulated supply pressure can run high. Sustained over-pressure fatigues pipe walls and fittings over time, making small failures more likely in older plumbing.
Ageing slab plumbing
Pipes cast into a concrete slab in older homes were often in direct contact with the concrete or wrapped in materials that have now broken down. Slab leaks are among the most expensive to leave unfound.
Non-invasive leak detection before anything gets cut
The old approach to a hidden leak was to start opening walls or chipping up the slab until the wet patch was found. It was expensive, messy and often damaged parts of the home that had nothing to do with the leak.
Ben uses his own ultrasonic leak detection equipment to pick up the sound signature of escaping water through walls, floors and concrete, and pipe locators to trace exactly where the line runs. That pinpoints the fault to within a small area before a single tile is lifted or a wall is opened.
And when the leak is on a buried line in the yard, he can dig down, repair or replace the section and backfill with his own mini excavator, so the whole job stays with one tradie. That means a smaller repair, less disruption to your home and a lower overall cost, with a clear upfront price once we know exactly what we are dealing with.

Servicing Perth's southern suburbs
We carry out water leak detection right across Perth's southern suburbs. Based in Kwinana and out through the south every week, so if you are in the area we can get to you.
Questions we get asked
The most reliable check is your water meter. Turn off every tap and outlet in the house, then watch the meter dial for two minutes. If it moves at all, water is escaping somewhere it should not. A rising bill with no change in habits is another strong signal.
Only if there is no other way to reach the pipe, and we always try to avoid that. Ultrasonic leak detection and pipe locators let us narrow the leak to a small area before anything is opened, so the work stays targeted and the repair stays manageable.
You get an upfront quote before any work starts. Cost depends on the access involved and how deep the pipe is, but because we pinpoint the location first, the repair is usually much smaller than it would be with exploratory cutting.
Most of the time, yes. Once we locate the exact position of the leak we access only that section, repair or re-route the pipe and pressure-test the fix. A full slab replacement is rarely necessary for a single point failure.
We cover Kwinana, Rockingham, Baldivis and right across Perth's southern suburbs. If you are nearby, give us a call on 0409 685 414.
