"I had an issue with a gas dryer install because the valve was faulty and leaking gas. I called Holt in the AM and Dale and Dee made it out to my house in Franklin that afternoon. I'm old and have been around lots of plumbers for various reasons. These two guys were the best I've ever encountered. Diagnosed and fixed the problem in quick time. They were thorough, professional and had great attitudes. Won't think twice to call them again. Thank you."
