Mario handled the situation very professionally and made a genuine effort to resolve the issue. Although the problem wasn’t ultimately fixed, he did everything he could to help and was clearly committed to finding a solution. I was a bit frustrated at times when I couldn’t reach him by phone, but I understand he was busy and short-staffed. Overall, I appreciate his effort, honesty, and professionalism throughout the process.
Mario is an absolute gentleman, my experience with Mario and his team from start to finish was amazing. We had an urgent issue at my 83 year old mother’s home with a serious blockage, Mario had the problem sorted and fixed without any issues and was a gentlemen to deal with. Keep up the amazing work 👌

Yes, licensed plumbers are qualified to fix, replace and install sewer lines. They handle a wide range of sewer-related issues including blocked drains, damaged pipes, tree root intrusion, collapsed sections, and full sewer line replacements. Depending on the severity of the issue, they may use non-invasive methods like jet blasting or CCTV inspections first, or perform full dig-ups if the pipe is extensively damaged.
In Melbourne, the cost to dig up and replace a sewer line typically ranges from $3,000 to $10,000 or more. Pricing depends on several factors including the length and depth of the damaged pipe, how accessible the area is, the type of ground or surface being excavated and any restoration required afterward such as concreting or landscaping. Reach out today for a tailored quote.
No, you can’t dig up your own sewer line. Digging up a sewer line must be done only by a licensed and registered plumber to ensure safety and compliance with local regulations.
