"I was very pleased with Sentry Access, from start to finish. I had the opener replaced. My older garage door (20+ years old) now operates and sounds like a new door. Richard, the technician who did the work, did an outstanding job on both the install and the "tune-up" of the door. I am 100% satisfied with the work from this company, and highly recommend them."

"He came on time, had all needed tools, knowledgeable. Made all repairs and adjustments. Was unable to remove large sliding patio door to see the rollers but was able to clean and adjust things so door is working well. Lock probably needs replacing but was able to adjust it to work well. Repaired screen door handle and cleaned rollers. Everything working as it should. I want to add, the work was done a week ago and I feel the door is working like new now. I only wish I had shown him the other one in the bedroom; I didn't realize how bad it was until I have the patio door working like new. Really happy with it. I'm sure I'll get him back out at some time."

"I contact AMG Doors through a recommendation from a friend. I contacted Michael and he was very knowledgeable about the different types of door materials and what material would work best for my area ( I get a lot of sun at my front door). Michael talked me into getting a thermatru front door and I obsoletely love it! AMG Doors already has a patio door on order for my home!"

"Hire my Husband built an arbor to go over our living room sliding door (it was not a kit). Dawson worked closely with us on the design to insure it was exactly what we wanted. The team who built it were very detailed and consulted with us on each step of the installation. We couldn’t be happy with the results! We plan to have them help us with another project."
