Inside a Typical Water Leak Detection Job
Water bills climbing for no clear reason, a patch of ceiling that stays stubbornly wet, or a meter dial that won't sit still, these are the calls where tracking down the source matters more than patching whatever's visible.
Thermal imaging and listening gear, our leak detection technology, locate a fault well before we'd need to dig up half the yard on a guess.
Is It Time to Call a Plumber?
A few signs point to a hidden leak rather than something obvious.
- The meter dial keeps turning with the whole house shut off
- A quarterly bill that's climbed with no change in how water's used
- Ceiling stains, wall discolouration, or a patch of slab that's warm
- A faint hiss from behind a wall or under the floor
- Odd green or soft patches in an otherwise dry lawn
- Water pressure that's dropped across the whole property
If the leak has already surfaced as flooding, Burst & Leaking Pipes is the more urgent job to call about.
The St Marys Angle on This Job
Mamre Road runs through some of the suburb's older housing, brick veneer and fibro built with slab-on-ground foundations that hide a leaking pipe well below the surface.
That style of construction means a slab leak often shows up first as a warm patch on the floor or a water bill that's crept up quietly, long before anything's visible from outside.
Finding it without breaking up a whole section of slab is exactly what detection technology is for.
What Your Fixed Quote Depends On
Depth and location drive the number here far more than what time you rang.
- Slab, wall cavity or open yard, each needs a different search method
- The amount of listening and imaging work needed to pin it down
- Access to the area once the leak's actual position is known
- A spot repair versus a longer stretch of pipe replacement
Take Mamre Road's slab-on-ground homes: locating a leak under concrete simply takes longer than finding one in open ground, and that time is what moves the cost. The quote itself is always free, and the number is fixed before repair work starts.
How We Work Through Water Leak Detection
Late or early, your water leak detection call still reaches a real person.
A plumber is dispatched for the water leak detection, same honest pricing as any hour.
We quote the water leak detection fixed on site, so there's no after-hours sting.
We fix it and hand you a lifetime labour warranty on the water leak detection.
Straightforward leaks in open ground are often found within a single visit; a slab leak under a home like those along Mamre Road can typically take longer to isolate, and that gets explained before we start.
Done Right, and Done to Code
Any repair following detection, whether it touches a water or gas line, has to be carried out by a plumber holding a current NSW licence.
Where a leak sits close to a gas connection, that section of the job passes to a licensed gas fitter rather than being treated as routine plumbing.
We'll explain what we found and what it means in plain terms, not trade jargon.
What the Search Actually Involves
An acoustic listening device picks up the sound a pressurised leak makes moving through pipe, even under a slab or behind tiles.
Thermal imaging shows up temperature differences in a wall or floor that often line up with where water's been sitting.
Neither method involves breaking anything open until we're confident of the spot, and we'll show you what we're seeing before any digging starts.
Why This Is a Job for Our Team
Upfront fixed pricing means the free quote we give you is the price you pay, whatever the search actually turns up.
A lifetime labour warranty backs the repair once the source is found, not just the detection visit itself.
Once the Leak's Found
A confirmed leak location doesn't always mean a big job. Plenty turn out to be a single fitting or a short section of pipe.
Where the damage runs further, especially under an older slab, we'll walk you through repair versus reroute options before deciding anything.
Either way, the same crew that found it carries out the fix, so nothing gets lost between one visit and the next.
Servicing St Marys and the Suburbs Around It
Slab leaks and rising water bills aren't limited to one part of town. Our detection gear travels to St Clair, Colyton and Cambridge Park just as readily as it does around St Marys itself.
If the leak's already visible as running water rather than a hidden drip, Blocked Drains or Burst & Leaking Pipes may be the faster call.

Common questions
Common Water Leak Detection Questions
The questions homeowners ask us most before booking this job.
How do I use the $65 off for water leak detection?
Mention it when you call and it comes straight off your invoice as a new customer. It applies to water leak detection the same as any other job on our books.
What's your method for water leak detection?
We start with the meter, watching it against every tap and appliance turned off, then narrow the search with listening gear and thermal imaging where it helps.
Could the problem come back after water leak detection?
Finding the exact leak means the fix addresses the real fault, not a symptom of it. A different pipe failing later is possible in an older property, but it's a separate issue, not a comeback of the same one.
Is there anything to do while I wait for water leak detection?
Note when you first noticed the water bill jump or the damp patch, and avoid digging around the suspected area yourself. That timeline helps us narrow things down faster.
Will you charge me to quote water leak detection?
No. The quote is free, and there's nothing to pay just to get us out for a look.
What does it cost just to attend?
Nothing at all. Whether the repair goes ahead afterward or not, attending costs you nothing.
