Overhead Door Company of Cortland, Inc. replaced our mechanism for opening our garage door. We had one and it wasn't working. There were some parts broken on it--the technician from Overhead Door Company of Cortland, Inc. showed us. He had the new part on his truck and he was able to replace it right away. The installer was a very personable, nice young man, and he worked the whole time he was here. He made sure that everything was installed properly. The company stuck to the estimate I had been given; there were no extra charges or hidden fees. The door works great now.
