A hidden leak can quietly run up your water bill, undermine your foundations and feed mould for weeks before you ever see a drop. Plumbing Bros provides fast, accurate leak detection across Perth, and because we are fully licensed plumbers, we do not just find the leak, we fix it, often in the same visit. Using non-invasive equipment, we pinpoint water and gas leaks in walls, floors, ceilings and underground pipes with minimal disruption to your property.

Signs You May Have a Leak

Leaks are not always obvious. These are the most common warning signs it is time to book leak detection:

  • Unexplained high water bills
  • A water meter that keeps ticking over when all taps are off
  • The sound of running water when nothing is turned on
  • Damp walls, ceilings or flooring, or watermarks that keep spreading
  • Water pooling in or around your property with no clear cause
  • A drop in water pressure
  • Musty smells, mould or bubbling paint near wet areas
  • Cracks, soft flooring or swollen skirting boards
  • A suspected gas leak, such as a rotten-egg smell near appliances

If you notice any of these, it is worth getting the source found early, before a small leak becomes a major repair.

Detection and repair in the one visit

Why a Leak Is Best Fixed by a Licensed Plumber

Some Perth companies only detect leaks, then leave you to arrange a separate plumber to carry out the repair. That means two call-outs, two waits and often two bills. Because Plumbing Bros are licensed plumbers and gas fitters, we can locate the leak and complete the repair in the one visit wherever possible, from repairing pipework, tapware and fittings to burst pipe repairs. It is faster, simpler and gets the problem sorted sooner.

As licensed plumbers, we can also provide the documentation you may need to apply for a Water Corporation leak allowance, which can help reduce a bill caused by a concealed leak.

Our Leak Detection Process

We use advanced leak detection technology to find the source of the problem. Our process includes:

  • Step 1
    Turn Off All Water Appliances to Ensure No Usage

    Ensure no water is being used in your house (turn off all water appliances, such as washing machines and evaporative air conditioners).

    Frequently Asked Questions

    How do you find a hidden water leak?

    We use non-invasive methods including acoustic detection, thermal imaging, tracer gas, pressure testing and moisture meters to locate leaks behind walls, under floors and underground, without unnecessary damage.

    Do you have to dig or cut walls to find the leak?

    Yes. We regularly locate leaks in buried water services, irrigation lines and beneath concrete slabs using specialist detection and pipe-locating equipment.
