Send a work orderTrustworthy started with a simple idea: turn up when you say you will, explain the job clearly, and do it properly the first time.
Our founder, Gary (Huynh), started in plumbing in 2000 and spent eight years learning the trade with an established Melbourne plumbing company. For more than two decades since, he has worked on homes, rentals and commercial sites across Melbourne, building a reputation for honest quotes and tidy, reliable work.
In 2017 the business became Trustworthy Plumbing & Building Pty Ltd. The name changed, but the way we work didn't. We scope every job properly, give you a clear price before we start, and treat your property like our own. Many of our clients have been with us for years, and that's the part we're proudest of.
Over the years we've grown from one tradesman into a small team of plumbers, and we've trained apprentices along the way. They learn the trade the same way Gary did: on the tools, doing the job properly.
Whether it's a leaking tap, a blocked drain or a renovation, you deal with people who care how the job turns out.
Call us, or email the details and a few photos.
