We just had a fabulous experience with Michael Petito/Petito Plumbing. We were influenced by those of you that had left earlier reviews, and you were right! We had a small issue that was becoming progressively more problematic. Mike came out quickly and fixed it, and even found and corrected an issue from a previous install (not his error, a prior contractor of ours had messed something up). Prompt, professional, and extremely kind. Cannot say enough good things. Highly recommend!

The day after we moved into our new home, we realized there was no hot water. I looked online for a reputable and affordable company and was very lucky that the first person I called was Mike Petito. He and his team have done several major jobs for me since then, and he has given me sensible advice about what items to prioritize and even helped me find reliable people for other jobs when my basement flooded in a heavy rainstorm. I feel very relieved to have found a local company that I trust completely who turns up when they say they will, does a great job and goes above and beyond. I recommend Petito Plumbing without reservation.

I know it may seem like chump change, but Michael saved me at least $100 — possibly way more! I called and left a message, and he got back to me ASAP. I explained the issue, and he walked me through some diagnostic/troubleshooting steps. I followed his instructions and got my water heater back up and running like I was the professional lol. Me and the wife are celebrating! Thank you, Michael — you definitely have yourself a returning customer! 💯

⭐⭐⭐⭐⭐ I cannot say enough good things about Mike Petito and his team! The other night, I texted Mike at 12:20 a.m. about a leak, and his team was at our house at 8 a.m. the next morning fixing it. That’s just one example of how he has gone above and beyond for us. Mike also took it upon himself to coordinate with our water treatment company to get our water softening issues resolved—without me even asking. And while I was visiting my mom in Springfield, Illinois, I FaceTimed him about her unusually high water bill. He took the time to walk me through what to check, even though he had absolutely no obligation to help. He’s simply a genuinely nice person who cares. He’s even helped with an unusual request: a baby fox had previously been living in our French drain pipes, and before I blocked off the openings, Mike helped me scope them to make sure there weren’t any animals still inside. His willingness to help me avoid accidentally trapping an animal meant so much to me. Everyone on his team (Jake, Christian and I can't remember all the names) have been incredibly kind, helpful, and an absolute pleasure to deal with. It’s not just how quickly they show up—it’s the thoughtfulness and care they bring with them. We’re so grateful to have found Mike, and I highly recommend him and his wonderful team!
