I can't say enough positive things about my experience with Randy and his crew. I hired Randy to help me turn a dilapidated old garage into a beautiful studio/cottage. The project took about 6 months. Randy was honest, incredibly transparent, fair, timely and super easy to work with. The crew worked hard, left the site neat at the end of each day and were always willing to answer questions or work with me as the project progressed. I've heard more than my share of construction horror stories going into this project and knowing how busy everyone was, I was nervous. I had zero issues with Randy. Not one that was of his doing and the ones that did arise, got handled professionally and as promptly as possible. I have received SO many compliments on my project and couldn't be happier with the work they did. Highly, highly recommend.
