  • I had a great experience with Dion’s. Got an appt. quickly, and the plumber, Dylan, was very professional and efficient. He also helped me work with the home warranty company, which was very much appreciated. I would definitely recommend Dion’s!

  • My parents have an older home, with older plumbing. We needed some help fast because the home only has one bathroom. Some one was out fast for a quote/ work done/ back to working order. Happy parents.
