Paul Francis – Boston University

 In the past several years of working with Ray and Dean they have been reliable and have provided quality service to the University. As a large university, with approximately 100 overhead doors in constant use, we require service frequently. Our calls are met promptly and efficiently. Their work is excellent and I would recommend them to any business or homeowner.

Leigh – Mansfield, MA

As a home owner and being married to a carpenter, my husband likes to do all the work in our home himself. When he wanted to call in someone else to do the garage doors, I knew that they must do excellent work. I was thrilled with the quality of their work and with all the suggestions that they made to us to help us select the style and color of the door. They were timely, cleaned up their mess and even removed the old garage door. Our new one looks fantastic. I would highly recommend them to anyone.
