I have used Overhead Door Company of Cortland, Inc. several times over the course of 21 years. Most recently, they Installed an overhead door and the operator. Everything turned out perfect--just the way I wanted it. They just do what they say they are going to do, and things always turn out very nicely. They do quality work. They went above and beyond by taking a quick look at one of their previous doors I had purchased and they did a little maintenance to it without charge. I highly recommend the Overhead Door Company of Cortland, Inc. They do quality work.
