Hidden water leak

What to look out for

Signs you’ve got a hidden water leak

Most leaks we get called to aren’t dripping in plain sight, they’re behind a wall, under a slab, or buried in the yard. If any of these sound familiar, it’s worth getting checked before the damage grows:

  • Your water bill jumped with no change in how you’re using water
  • A damp patch, stain or bubbling paint on a wall, ceiling or floor
  • A musty smell or mould that keeps coming back after you clean it
  • The sound of running water when every tap is off
  • Warm spots on the floor (a sign of a hot-water line leaking under the slab)
  • Cracked, lifting or loose tiles in a bathroom or laundry
  • Water meter still ticking over after you’ve turned everything off
  • Low water pressure that’s crept up on you

A small concealed leak can waste thousands of litres and feed mould and timber rot for months before you spot the real cause. The sooner it’s found, the smaller the repair.

Not sure if it’s a leak? Call us and describe what you’re seeing, we’ll tell you straight whether it’s worth a detection visit.

Our methods

How we find your leak without wrecking your home

The old way to find a hidden leak was to start opening up floors and walls until you hit water. That’s expensive, messy, and you’re paying to repair the damage on top of the leak. We don’t work that way. We use non-destructive detection equipment to locate the leak precisely first, so the only thing we open up is the small section that actually needs the repair.

Acoustic Leak Detection

Acoustic leak detection

Pressurised water escaping from a pipe makes a sound, far too faint for you to hear, but not for our ground microphones and acoustic listening gear. We trace that sound to its source to locate concealed pipe leaks under floors, slabs and paving without lifting them.

Thermal

Thermal imaging

A thermal imaging camera reads tiny temperature differences across a surface. A hot-water leak warms the area around it; a cold-water leak cools it. We use thermal imaging to map a leak behind tiles, plasterboard or concrete and confirm exactly where it’s tracking.

Pressure testing

Tracer gas and pressure testing

For trickier leaks, we pressure-test the system to confirm there’s a leak and how bad it is, then introduce a safe tracer gas that rises to the surface at the leak point. It’s one of the most accurate ways to find small or intermittent underground water leaks.

What We Fix

Leaks we find across Sydney

We detect and repair every kind of concealed water leak in Sydney homes and buildings:

Concealed pipe leaks in walls, ceilings and floors

Pipes leaking under a concrete slab

Underground and water-main leaks

Hot-water and recirculation-line leaks

Shower, bathroom and wet-area leaks

Toilet, cistern and concealed-cistern leaks

If your problem is a leaking drain or sewer pipe rather than pressurised water, we’ll find that too and our sister specialists at Ready Set Reline can reline the damaged section without excavation.

Chris and the team were the A-team when it came to locating a tricky leak under the property. They never gave up, went above and beyond, and fixed the problem. Always clean, kind, and on time. Highly recommend.

Our Minimum Standards

No boot prints, no mess, no exceptions

Clean uniforms. Clean boots. Drop sheets down before we start. Tools, packaging, and offcuts out with us when we leave. If we need to open a wall or ceiling, we’ll tell you first and leave the area tidy.

  • Drop sheets laid before any work begins
  • Shoe covers worn inside your home
  • All debris, offcuts, and packaging removed when we leave
  • Work area left clean and tidy, not “tradie tidy,” actually tidy
  • Any access to walls, ceilings, or other areas discussed with you before we touch them
  • A walkthrough of the completed work before we pack up

You won’t find boot prints on your tiles or copper shavings in your bath. That’s not a bonus we charge for. It’s the minimum standard.

FAQ

Leak Detection Frequently asked questions

Straight answers to the things people ask us most when something’s gone wrong.

Yes. Ready Set Plumb uses non-destructive methods, acoustic listening equipment, thermal imaging cameras, tracer gas and electronic pipe locating, to pinpoint a leak before anything is opened up. The repair is then confined to the small section that actually needs work, instead of cutting open floors and walls to search.
Yes. Slab leaks are one of the most common jobs we handle. Using acoustic detection and thermal imaging, we locate the leaking pipe beneath the slab and mark its position precisely, so the repair targets one small area rather than the whole floor.
Most residential leak detection takes one to two hours, depending on the size of the property and how accessible the plumbing is. In most cases the leak is located and repaired in the same visit.
Yes. If your insurer needs the leak located and documented, we can provide a report detailing where the leak was found and its likely cause.
