Over the years we keep coming back! Travis just did a stellar job replacing our outdoor water spigot. From time to call to complete job done about six hours! Awesome. Price a little steep but great work costs money so I’ll take it! Bobby just installed a toilet for us it looks great! He was patient and the dogs liked him too! Great job. The price a little high but the work exceptional! Derrick just fixed our main line he too was excellent help! Came early, put on plastic slippers to protect our floor. TOP NOTCH WORK! Donnelly's is our go-to for plumbing! A few years ago Rob B. from Donnelly's helped us. He was great! Rob B. has been to my house twice for big jobs - installing a water heater and two sink repairs and a toilet replacement. A tad pricey but I'm extremely satisfied with the work. Thanks!
