Plumber using thermal imaging and acoustic equipment to find a hidden leak

How we can help

Some leaks are obvious. Others hide under slabs, inside walls or underground, slowly damaging your home and pushing up your water bill.

We use thermal imaging, moisture meters and acoustic listening equipment to narrow down where a leak is before opening anything up — so repairs are smaller, neater and cheaper.

Common problems we solve

  • Water bills higher than normal
  • Water meter ticking over with all taps off
  • Damp patches, bubbling paint or mould
  • Warm spots on floors (hot water leaks)
  • Soggy ground in the garden
  • Leaking showers and wet areas

What to expect

  1. 1

    Confirm a leak

    We test the meter and isolate sections of the system to confirm and narrow down the leak.

  2. 2

    Pinpoint it

    Thermal imaging and acoustic equipment help us locate the leak without guesswork.

  3. 3

    Show you

    We show you where it is and explain the repair options and costs.

  4. 4

    Repair

    With your approval, we repair the leak and retest the system.

Pricing & quotes

We'll explain the cost of the leak investigation before we start. The repair is quoted separately once we know where the leak is and what's involved.

* The $0 call-out fee applies when you go ahead with the quoted work. If you decide not to proceed after we have attended and quoted, a $49 dispatch fee applies. See all offers & our guarantee.

Frequently asked questions

How do I check for a hidden leak?

Turn off every tap and water-using appliance, then watch your water meter for 15–30 minutes. If it moves, there's likely a leak somewhere.

Can you find a leak under a concrete slab?

In many cases, yes. We use thermal imaging and acoustic equipment to narrow the location before any concrete is cut.

Can I get a concession on my water bill for a leak?

Some Melbourne water retailers offer leak allowances once a licensed plumber has repaired the leak. We can provide a report to support your application.

  • Slow drain had been driving us mad for months. They arrived the next morning with camera equipment, pinpointed the blockage and fixed it on the spot. Very professional.
