A garage door that has a broken spring has nothing to support its weight. The size of the door and the type of spring system determines how difficult opening the door will be. A garage door should not be opened until the spring is repaired. However, when you need to get your car out of the garage, it may be necessary if you cannot wait for the repairman. Use extreme care when opening a garage door in this manner.
A standard double garage door is 7 ft. high by 16 ft. wide. Standard single doors are 7 ft. high by 8 or 9 ft. wide. Because the doors are so large, few home centers and only some garage door stores keep many doors in stock, so expect to order one instead of buying it off the shelf. Garage doors are available in wood, fiberglass and steel. Steel doors, like ours, are light, maintenance-free, affordable, readily available, and have an insulating value as high as R-19.
