 Trustindex verifies that the original source of the review is Google. Z Plumberz is amazing! I was able to schedule service easily. They were quick to respond and get me on the books ASAP. When Brenden arrived he was pleasant, courteous, took time to explain the options, and he did a great job pivoting when what I thought was the issue, in fact, wasn’t the issue. He uncovered the real problem and contacted the team who quickly got Brian to come out with the proper equipment needed to correct the issue! They then cleaned up and all was well again! Highly recommend this team! Top to bottom- office staff to plumber- they were great!

 Trustindex verifies that the original source of the review is Google. This was my first time using Z Plumberz of Downriver, and they have earned my business for any future plumbing needs.

My service technician, Devin Sawmiller, went above and beyond. He was extremely professional, detailed, and took the time to thoroughly explain my situation and what repairs were needed. Devin replaced my sump pump and also discovered a separate leak in my PVC piping that needed attention.

What impressed me most was that he stayed beyond normal business hours to make sure everything was completed correctly. Throughout the entire process, he explained how the issues occurred, answered all of my questions, and handled the work with confidence, professionalism, and a positive attitude.

Devin, thank you for the outstanding service. I truly appreciate your hard work and dedication. Have a great vacation—you’ve earned it! - Joe
