 Trustindex verifies that the original source of the review is Google. They are super easygoing, extremely knowledgable, and not sales-y at all. It's difficult to come by honest and reasonably priced plumbers these days, and so I was really happy to work with them. Also supporting a small family business! They did a solid diagnostic assessment before proposing any work to fix the water pressure in our house. Would highly recommend!

 Trustindex verifies that the original source of the review is Google. We had an emergency clog that turned into a big time sewer line repair job, and the Bob Oates team was timely, thorough, and helpful throughout. Prescott was a great project manager and kept us updated and informed the entire process. We're so glad we contacted them first!

They responded to my call quickly, showed up on time, and did an outstanding job on the plumbing work in my home, including my sinks and other maintenance. Their workmanship was excellent, everything was done professionally, and they stand behind their work with a 100% warranty, which gave me great peace of mind. It’s hard to find a company that is this reliable, honest, and responsive. This has been the best plumbing service I’ve ever experienced. I will definitely use them again and recommend them to all my friends and family. ⭐⭐⭐⭐⭐

 Trustindex verifies that the original source of the review is Google. Had the pleasure of being helped by Autumn today. She was friendly, professional, and very knowledgeable about the services this company offers. I wasn’t quite sure what would be right for me, as I’ve never dealt with major plumbing issues before, but she was able to help me choose the services that would best suit my needs. I appreciate her answering all of my silly questions in a way that I could understand. I will definitely be recommending Bob Oates to my friends and family. Thank you, Autumn!

 Trustindex verifies that the original source of the review is Google. I just had Henry and Jesse come over to my condo to help me out with a leaking dishwasher... these guys were rockstars! They gave me a courtesy call and were here on time to the minute! Total professionals as soon as they entered the door, asking about my shoe policy and just pleasant people! As I fumbled around to find my dishwasher literature, they already had it pulled up and were running an initial cycle to troubleshoot the problem. Within minutes Henry diagnosed the problem, the two excused themselves to grab a few tools and were back in moments... it couldn't have been more than 10 minutes and they had resolved the problem and were running a cycle to verify their work. They gave me some additional feedback on what may have caused the issue, how to avoid it in the future, and then proceeded to humor me by answering a few unrelated questions I had about my washer. Great guys and great experience! This is now my second time dealing with the Bob Oates team and both times have been a great experience... Local, first rate service, and family owned; I'd recommend them to anyone! Whether you're a GC or a homeowner, having a great plumber in your Rolodex is a must; Bob Oates is my go to and should be yours as well!

 Trustindex verifies that the original source of the review is Google. Bob Oates Plumbing came recommended by our neighborhood, well-known real estate agent. We have used them a few times-once for a clogged kitchen sink situation and also for kitchen faucet installation. They have been timely, honest, knowledgeable and nice guys who make sure the job is done right. They can also order fixtures/products for you and they will install. Highly recommend!
