It you have a tilt-up door, you are looking at a $150 – $200 repair or replacement. If it’s a roll-up door it’s going to cost you more. Roll-up door spring repair or replacement is usually around $200 – $250 for a 2 car door. If the brackets need to be disassembled to remove the springs due to the shaft not sliding sideways enough it will cost you an additional $50 – $100.
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.
