What may be happening with your garage door
Garage door springs hold significant tension and counterbalance the weight of the door. A broken or poorly matched spring can leave a door immovable, uneven or unsafe. This is not a good do-it-yourself repair: the correct spring size and safe installation procedure matter.
Signs it is time to request professional help
Stop operating a door that is off track, hanging unevenly or supported by a broken spring or cable. Do not stand or work beneath an unstable door.
