Water leak detection

Think you have a leak? Don't start digging.

Hidden leaks drain your wallet and damage your home. Our tracer-gas detection finds the exact spot – usually within the first hour – so we only open one tile, not your whole floor.

How non-invasive leak detection works

  1. STEP 1

    Confirm the leak

    A meter and pressure test tells us whether water is escaping – and roughly how much.

  2. STEP 2

    Introduce tracer gas

    A safe nitrogen-hydrogen mix is pushed into the drained line. It escapes wherever water does.

  3. STEP 3

    Pinpoint it

    A sensitive detector picks up the gas through tiles, concrete, paving and soil.

  4. STEP 4

    Fix one spot

    We open only the marked point, repair the pipe and pressure-test the result.

Check for a leak yourself

  1. Close every tap and make sure no toilets are refilling.
  2. Take a photo of your water meter reading.
  3. Wait 30–60 minutes without using any water.
  4. If the reading has moved, you have a leak – call us.

Warning signs

  • Water meter turning with every tap closed
  • Unexplained jump in your municipal bill
  • Damp patches, lifting tiles or a soggy spot in the garden
  • Sound of running water when everything is off
  • Cracks or mould near pipes

Questions

Will you need to break my floors? +

Only at the exact leak point once it has been confirmed – usually a single tile or a small hole, not a trench.

Is the tracer gas safe? +

Yes. It is a non-toxic, non-flammable nitrogen/hydrogen mix that disperses harmlessly into the air.

How long does it take? +

Most residential leaks are located within the first hour on site.

Will my insurer pay? +

Many policies cover leak location. We provide a report with photos of the leak point.
