The evidence — in reviewers' own words
Critical
“This guy charged me $325 to install a faucet. 45 minutes of work for one person. In context, an electrician installed two ceiling fans, two outdoor lights, and a new outdoor outlet for $350 during the first week of September.”
Positive
“I had a toilet issue that was driving me crazy, and Mastermind Plumbing saved the day! They were super friendly, explained everything clearly, and fixed the problem fast. No mess, no hassle—just great service. I’m so grateful for how easy they made the whole process. I’ll definitely be calling them again for any plumbing needs.”
“Highly recommend! We had an excellent experience with Mastermind. They were prompt, professional, and clearly knew what they were doing. The work was done quickly and correctly, and they made sure we stayed informed the entire time! Its hard to find reliable service these days, but Zach went above and beyond. We’ll definitely be calling them again for any plumbing needs!”
