What customers say

Based on genuine customer reviews

Households needing hot water systems replaced or repaired form the bulk of the work described, and the accounts of that work share a consistent tone. Several customers describe a process that moves quickly from the first call to a finished installation, with diagnostics and quotations arriving within hours and the new unit often in place the same day or the next.

Reviews regularly refer to the friendliness and professionalism of the tradespeople, naming Logan, Nick, David, Vince and Adam, and note that each explained the options clearly, answered questions patiently and offered practical advice, including checking whether a unit was still under warranty before paying for a replacement. An aspect raised across a number of reviews is the care taken with existing fittings and the tidy finish left behind.

Beyond hot water work, the reviews cover gas fitting such as an oven leak repair and the planned installation of a new gas oven, plus general plumbing faults sorted on the day promised. Customers value the clear communication before and after the job, the willingness to work around limited availability, and the fair pricing quoted against several competitors. Problems were handled by returning promptly and keeping customers informed until the work was complete.

I was quoted for a new hot water system but then Mainline assisted me to go through warranty and Rheem gave me a brand new one covered to replace the old one. 2 very friendly and professional gents attended and replaced the system, also offering valued care advice. Thank you to Nick and Mainline for going above and beyond to sort this one out. Warranty is worth checking first. This system was under warranty for 12 years. Lovely hot water again. Will use this company again for sure.

Best price in the area after getting 5 seperate quotes for the same gas storage system. Excellent lead time. Adam was the plumber who attended, highly professional, friendly and obviously takes a lot of pride in his workmanship. Really good plumbing company to work with.

Fantastic experience with a fabulous prompt resolution. Our water meter leak was discovered late in the day, and I was able to make contact out of hours (this in itself fabulous) with Mainline Plumbing. To then being able to have our issue fabulously repaired promptly the next day. Thankyou for making this such an easy process, so quickly resolved. Much appreciation.

Would highly recommend their services. Recently engaged Mainline Plumbing to install services to four new blocks in Bunbury. Drama free job, liaised with Electrician and works completed professionally. Nick kept me in the loop throughout so no unexpected surprises, always available to discuss any concerns. Garry

I was extremely impressed with Mainline Plumbing from the very beginning, I felt genuinely welcomed and valued as a customer. They were more than willing to work around a specific time that suited me, which I greatly appreciated given my limited availability. Vince, the plumber, was exceptionally accommodating throughout the entire process. He took the time to clearly explain everything, provided me with different options to choose from, and made sure I felt comfortable with the decisions being made. His warm and friendly nature stood out, and he wasted no time completing the job to a very high standard. His dedication to achieving the best outcome for me was evident, and he even cleaned up thoroughly afterwards. Nick’s follow-up after the work was completed was also greatly appreciated. It really demonstrated that customer satisfaction is at the forefront of the service Mainline Plumbing provides. The professionalism, communication, and genuine care shown by the team made this an outstanding experience from start to finish. I would highly recommend Mainline Plumbing to anyone looking for reliable, professional, and customer-focused service.
