Reviews

What customers say

Customers describe prompt, professional work, and one repeat customer singles out Tim's tidy service. One customer said the company fit her in the same day for an upstairs leak; another said Tim returned the next day after she noticed low water pressure following the work. A repeat customer objected to a water-softener replacement quote, citing a fixed income and saying she bought and installed her own unit.

Customer Reviews

Michael Mangum

This is our fifth job with 100% Plumbing. We are always satisfied with their service and their work. We have recommended them to several of our neighbors and will continue to do so. Tim did our work today and he was prompt, professional and tidy. As usual, for 100%. Happy, repeatcustomers.

We found a leak coming from our upstairs and 100% plumbing was able to fit us in the same day! Nate was fantastic, kind, and extremely knowledgeable. He was able to fix the leak right away. Great experience and highly recommend this company!

Frank Bauman

Needed some water heater maintenance done and was not happy with a previous plumbing company. I also needed some finishing work done on a bathroom vanity. Coworker recommended 100% and glad I went with them. Mike was on time, extremely professional and answered all my questions. These guys are fantastic and I highly recommend them.
