Leak detection specialists in Sydney

A hidden leak wastes water and quietly damages floors, walls and foundations. We isolate sections of your system to narrow the search, then pinpoint the leak with acoustic listening gear and thermal imaging.

You get the location and a written price for the repair, rather than an invoice for exploratory demolition. If concrete has to come up, it is one small opening rather than a trench across your living room.

How we find a leak without breaking walls

Pressure isolation

We shut off and test sections of the system to narrow the leak down to one line.

Acoustic and thermal

Ground microphones pick up water escaping under the slab or lawn, and a thermal camera shows where it is soaking through.

With the leak pinpointed, only the spot over the leak is opened, or the pipe is rerouted and nothing is broken.

Signs you have a hidden leak

  • A water bill higher than usual with no change in use
  • The water meter moves with every tap turned off
  • Warm spots on the floor or damp carpet edges
  • Damp skirting, lifting floor edges or a musty smell
  • A patch of lawn that stays green or soggy
  • Pool level dropping by centimetres a day

Melissa DavisGoogle review

“Definitely a 5 star experience. Anthony from Bayside Plumbing arrived on time, and was friendly and professional. The repair was completed efficiently, and everything was left clean and tidy afterward. His communication was excellent throughout the process, and I appreciated the honest advice provided.”

Margaret LyGoogle review

“After getting several quotes, Max stood out with both the best price and the best solution for my situation. He took the time to problem solve with me, gave me multiple options, and genuinely thought about what would work best for my needs and budget. They were professional, polite, and very respectful of my home.”

Charl DuplooyGoogle review

“Our experience with Bayside was exceptional. Tilley and Yanni went over and above from the start and were exceptional in dealing with a complicated matter and resolving it professionally.”

Matt PenningtonGoogle review

“They responded to our call promptly, and listened to our concerns before equipping themselves to come out. Our precious engagement ring had been flushed down the toilet and they managed to retrieve it thankfully for a reasonable price. Special shoutout to Harry the plumber.”

Aran MatkevichGoogle review

“Quick response and neat job.”

Morad RushdiGoogle review

“All done on time, very professional technician.”

A written report for your insurer

Resulting water damage is often covered by insurance. Our written report gives the location and cause of the leak, which is what insurers ask for.

If it turns out to be failed waterproofing or a pool shell, we tell you plainly so you call the right trade.

Questions about leak detection

How do you find a leak you can’t see?

Pressure isolation narrows it to a section, then acoustic gear hears the escaping water and thermal imaging shows the temperature difference.

Do you have to dig up my floor or yard?

Only where the leak is, and only once it is pinpointed. Often rerouting the pipe avoids breaking the slab at all, and we price both so you can choose.

Can I claim it on insurance?

Resulting damage is often covered. Our written report with the location and cause is what insurers ask for.

How do I know it’s under the slab?

Warm spots underfoot, damp carpet edges, and a water meter that moves with everything turned off are the usual signs.

Do you repair pool leaks too?

We repair the plumbing side. If it is the shell or the liner, we will tell you plainly so you get the right trade.

What does it cost?

There is no call-out fee. Once the leak is found you get a written fixed price for the repair before we start.
