I can’t even begin to say enough good things about MGC! I work in remodeling and deal with contractors all the time. MGC has been the most professional, easy to work with, proficient, and organized contractor I have ever worked with. Their bid was accurate, and the service I received from the team was unparalleled. Above all, communication was top notch! I was kept in the loop every step of the way and never wondered what was going on with my project. I would recommend them in a heartbeat, and will continue to use them for every single commercial project I have in the future. Andy and Jacob were my main points of contact and they were both awesome. Everyone from the team was wonderful. I’m so glad I went with these guys.
