Paul22 September 2025Trustindex verifies that the original source of the review is Google. I called Josh at Mint Plumbing and Relining, because of a blocked waste pipe from our apartment block. He was professional and courteous on the phone, plus gave a quick response time of 2 hours. Onsite site his manner was knowledgeable, tidy, and efficient. With a modern set up on his ute, he was able to provide a service where as the job was completed within half an hour. As this blockage affected several units in the complex, it was good to know, he was local and had the ability to get to us within a few hours. Great outcome for the residents of our units. Keep up the great work Josh, and the team at Mint Plumbing and Relining. Will be using them in the future for our strata plumbing. A couple years in using Mint plumbing and we have had Jamie out for gas meter re- piping and recently jetting one of the lines for a blockage. Helpful, professional and good to see the same faces time after time. Thanks Miranda Smidmore22 September 2025Trustindex verifies that the original source of the review is Google. Jamie from Mint Plumbing turned up for a last minute emergency and did an amazing job fixing the problem in the block.
