We have an older garage with a very heavy wooden door, too heavy to lift without the spring assist. The spring required replacing, the service tech from Stampede Overhead Door responded the same day and replaced the necessary parts quickly. He also took the time to service and tune up the rest of the door mechanism and opener. We were very impressed with the efficiency and taking the time to do more than we had expected. Very courteous and professional, have and will continue to recommend their service.
