Montell Construction did an excellent job building our three season room. It was our first time using them, and everything turned out great. They do a great job. They're obviously dedicated to their work, but the project took longer than we were expecting. We were expecting the work to be done by Thanksgiving, but they just finished today. So it was two weeks late. The workers, and the work, were excellent. Our only objection is it took longer than we were expecting.
