I contacted Complex Plumbing when my shower was dripping. They sent a plumber within an hour to my place. The plumber checked the issue and explained me how he was going to fix it. He completed the work in no time. The work was perfect and I did not experience the issues after that. I would definitely contact Complex Plumbing for any plumbing issues.

The team provided an amazing service right from when I called them. The plumber provided an affordable quote while there are other plumbing companies charging exorbitant prices for the same problem. Thank you Complex Plumbing.

The old pipe in my house was deteriorated and I called Complex Plumbing. The plumber visited my house to inspect the pipe. He used the CCTV camera to assess the exact location and also showed me where and what the issue was. He replaced the pipe soon after and the price was reasonable. I would recommend Complex plumbing for their excellent service.

I was amazed their great service and communication throughout. I found Complex plumbing when I was looking for plumbers who provided service for gas leaks. They came and fixed the gas leak. They also gave me some tips on how to prevent the gas leaks. Highly recommended for plumbing in Sydney.

I wanted a new hot water to be installed in my new home. The plumber from Complex plumbing assessed my requirements and recommended me a few hot water heater models to suit my needs. I picked a model and the installation process was smooth. Thank you Complex plumbing the expert advice and the professional service.

The plumber impressed me with his attention to detail. I had called the team for blocked sinks and he detected a major block in the drains as well. Thanks to him, it had saved me from spending a huge amount of money if the blocked drains were undetected for one more week. Great work, Complex Plumbing!
