    I just had to tell everyone about the experience I had with Donnelly’s and especially The best plumber in the world. I had a leak in my second bedroom overhang above the closet. Travis came to my house and put me at ease. He was so polite, knowledgeable and respectful. I showed him what the problem was. He looked at the room above it and the bathroom upstairs. He told me that he’d have to cut some of the drywall out to see where the problem was coming from and the price. After he found the problem he made me aware of the problem and told me exactly what he’d have to do to fix it. If I had questions, which I did, he explained very thoroughly to me so I’d understand completely. At every aspect he told me the price. He had me look at everything he was doing and where the problem was. After I agreed he got the parts and completed the fix , and of course showed me. Stayed to make sure nothing leaked anymore. I’ve never met anyone so knowledgeable, professional yet friendly, so proud of doing his job but mostly helping people. You can tell he loves what he does and he does it competently! Thanks so much Travis! You’re the best!!!!
