Black Buck Plumbing & Gas offers leak detection in Penrith for homes and small businesses. Some leaks are easy to spot, like a dripping tap. Others stay hidden and show up later as a high water bill.

We are trained plumbers based in Cambridge Park, and we can quickly identify potential leaks using a dye test. There is no call-out fee, and you get a fixed price before any repair starts. Call us on 0451 071 272 or use the Book Now button.

Signs you have a hidden leak

A leak does not always look like a leak. We look for water leaks and gas leaks, and the signs below are a good reason to call.

Gas appliances not working properly

If a gas heater is hard to light, the cause could be a valve fault or a leak in the gas line. A leaking gas line is a serious safety hazard for you and your family. If you think you can smell gas in the home, call a plumber straight away.

Droplets of water in the sink or shower area

You might find a mysterious puddle in the shower after it hasn’t been used for a long time. That is a clear sign of a water leak. Often it is an easy fix, such as new tap washers, but it is worth having a plumber check it.

Wet or cracked grout in the bathroom

Wet or cracked grout is never a good sign. It often means water has become trapped between the tiles and the shower floor, and your bathroom waterproofing may be damaged. Get a plumber in before it gets worse.

A drip you can hear but cannot find

A drip in the middle of the night can drive you crazy. If you can’t trace the noise, we can find where it comes from.

How we find a leak

  1. You call us or book online and describe what you have noticed.
  2. We inspect the area and find the source, using a dye test where it suits the job.
  3. You get a clear, fixed quote for the repair before any work begins.
  4. We fix the leak and clean up our work area before we leave.

If the leak turns out to be a damaged pipe, we will explain your options. For a pipe that is cracked or root-damaged, pipe relining can repair it without digging. A dripping tap or sink fitting is covered by our sink and tap repairs.

What does leak detection cost in Penrith?

The price depends on where the leak is and how hard it is to reach. A visible drip under a sink is a smaller job than a leak behind a wall or under a floor. Access, pipe condition and the true cause all affect the cost.

Most leaks can’t be priced exactly over the phone, because they often hide bigger issues. That is why the plumber sees the job first.

We don’t charge a call-out fee. If fault-finding, testing or a detailed inspection is needed to quote accurately, a diagnostic fee may apply. If you go ahead with the work, it is deducted from your final invoice. You get a fixed upfront quote before work begins, with no hidden costs.

If water is flooding out, turn off the water at the meter if it is safe to do so, then call us. After-hours and emergency work is charged at a higher rate, and we explain that before we attend.

Leak Detection questions

How do I know if I have a hidden water leak?
Watch for a puddle in the shower when it hasn't been used, wet or cracked grout, or a drip you can hear but can't find. Hidden leaks can also lead to costly water bills. If you notice any of these, call us.
What should I do if I smell gas?
If you smell gas, turn off the gas supply at the meter if it's safe to do so, open doors and windows to ventilate the area, and contact us immediately. If the smell is strong or persistent, move to a safe area and call emergency services.
Do you charge a call-out fee for leak detection?
No, we don't charge a call-out fee. If testing or a detailed inspection is needed to quote accurately, a diagnostic fee may apply. It is deducted from your final invoice if you go ahead, and we explain it upfront.
Do you test for gas leaks?
Yes. We carry out proper gas leak testing using professional equipment to ensure your gas system is safe and operating correctly. Testing is essential after installations or repairs.
