We have used Overhead Door Company of Cortland, Inc. to take care of the overhead doors both at our home, and at the business. They are unbelievably prompt when we call them. When I scream for help, they run! The last time we used them, the door at the business had come off the track, and it was hanging on one side, about to fall off. I called them and by the time I got home, they called me back to let me know they already had it fixed. They attached the tracks back to the building, and rehung the door, and now it raises and lowers just like it is supposed to! This is a great company, and I highly recommend them!
