Great experience with Highlander, highly professional and reliable.
Plumbing in Sydney is never cheap so it's be the work is done right, having used a "Cash" plumber I was left with a leak and no one to speak to, Highlander fixed the issue and I have had no other issues.
The Cash plumber took $700 for the work, and Highlander took a bit more however I clearly wish I has spent the money in the first place to get the job done right.
Approximate cost: $900
