Why Professional Leak Detection Matters

Hidden leaks can cause serious damage if left undetected. Water leaks may weaken structures, increase water bills, and lead to mould growth, while gas leaks pose significant safety risks.

Working with a professional ensures:

✔ Accurate, non-invasive leak detection
✔ Early identification of hidden issues
✔ Prevention of costly structural damage
✔ Safe handling of gas-related risks
✔ Long-term protection of your property

Early leak detection also helps reduce water waste and improve overall system efficiency, and may uncover other plumbing issues that need attention across your property.

What Our Customers Say

Just called these guys on a Friday night, late for an emergency issue of a water leak in my house. Response was so fast, fixed the issue within no time, a good price too for a 9 pm call out, and super professional. Can’t thank them enough, highly recommend and will use again if I ever need a plumber.

Kyle Northey

D Floor icon

Our office kitchen had a leak that started to flood inside our cupboards, which we called Civic, since we used them for a separate issue in our office building. Chris sent someone out immediately to assess the situation and work on fixing this up in no time. Civic explained what had happened and what they would do to fix the problem. Extremely pleasant and efficient!

Richard from Civic called today and located the leaking pipe in our front yard.
Great job and a great price. Would highly recommend them to anyone.

Tracey Nunziato

I’ve used Civic Plumbing a couple of times. Started with needing a new hot water system, he and his offsider were prompt and gave great advice. Next needed my leaking roof fixed, replaced sheets, all good now, then new kitchen, and Chris and his team put in all my appliances, including new lines. He actually recommended the Kitchen guy, United Kitchens, who was a God-sent. Great to have a plumber you trust.

Tracey Nunziato

Suzanne Hardy

Chris and his team were very professional. They did a great job fixing our gas leak. On seeing the work they did, I gave them another job on the spot. The boys were friendly and clean, leaving no mess. I would highly recommend Civic Plumbing.

Suzanne Hardy

We just moved into a new unit and discovered it was full of plumbing-related issues. Chris gave us perhaps the best service I’ve seen: prompt and punctual, a fair price quoted, and an excellent and efficient job done. Can’t recommend enough!
