How to Tell This Job Can't Wait

  • A water bill higher than usual with nothing changed in day-to-day use
  • The water meter keeps turning over even with every tap shut
  • A damp patch, musty smell or soft spot in flooring with no clear source
  • A warm patch on the floor that suggests a hot water line underneath
  • Mould appearing on a wall that isn't near a bathroom

What We Handle Under Water Leak Detection

Hidden leaks aren't always where you'd expect, which is why guessing rarely finds them.

Slab leaks. Pipework under the concrete floor itself, usually found through sound and thermal patterns rather than digging blind. Often the hardest to spot without the right gear.

Wall and ceiling leaks. Water tracking sideways from its actual source, so the stain rarely sits directly above or beside the problem. Chasing the stain alone usually opens the wrong wall.

Underground supply leaks. A line between the meter and the house losing pressure gradually, often only obvious on the bill. The lawn staying suspiciously green in one patch is another giveaway.

Fixture and appliance leaks. Slow losses around a toilet, dishwasher or washing machine connection that build up over weeks. Small on their own, but they add up fast on a quarterly bill.

Water Leak Detection and St Clair's Older Housing

Along streets like Blackwell Avenue, houses from that original 1980s-90s build still carry a lot of their first pipework, whether copper, galvanised steel or early poly fittings. None of it was built to last forever, and plenty of it is now well past the point where a slow leak becomes likely.

A leak in that older pipe rarely announces itself. It's usually a bill, a smell, or a patch of ground that stays wet after a dry week.

Newer poly fittings on more recent renovations tend to behave better, which is part of why the older streets keep us busiest with this particular job.

What Affects the Price of Water Leak Detection

  • Whether the suspect spot sits under slab, inside a wall cavity or below ground
  • Whether acoustic listening alone locates it or thermal imaging is also needed
  • The size of the area that needs checking based on what you've noticed
  • Whether any exploratory access work is required to confirm the source
  • Follow-up repair, priced separately once the leak's actually found
  • Whether the leak's on your side of the meter or needs a different authority involved

Older copper and galvanised runs, common in streets from that first 1980s wave near Blackwell Avenue, don't carry sound the same way newer poly pipe does, so tracing them properly sometimes needs an extra pass.

Our Water Leak Detection Process, Start to Finish

  1. When you call about water leak detection, we talk you through the safe first step.
  2. Our plumber arrives and makes the water leak detection situation safe before anything else.
  3. You approve a fixed price for the water leak detection with no surprises.
  4. We carry out the water leak detection and stand behind it with a lifetime labour warranty.

Most leaks are located within the one visit. An especially faint or deep slab leak can occasionally need a second pass with different equipment.

Either way, you're not left guessing in between. We'll tell you what we've ruled out as well as what we're still chasing.

What NSW Requires for This Work

Locating a leak is one thing; fixing what it uncovers is another, and NSW rules require that follow-up repair work to be carried out by a licensed plumber.

Detection equipment doesn't require special certification to use, but interpreting what it's telling you correctly takes real experience, which is where a proper diagnosis earns its keep.

Anyone can point a thermal camera at a wall. Reading it correctly, and knowing when it's wrong, is the actual skill.

The Difference We Bring to Water Leak Detection

We're a family-run team, and that shows up here as patience: we'd rather spend the time finding the actual source than open three walls guessing.

The same no-surprises approach applies whether it's the detection itself or the repair that follows it.

A quote that only covers finding the leak, with the fix priced separately once we know what we're dealing with, is standard practice on our jobs.

A leak traced back to a worn fitting rather than the pipe itself often becomes a same-visit leaking tap fix.
