Broken torsion springs: this is the most common garage door repair. On an average, a garage door spring has a life span of 8-12 years depending on a manufacturer and the quality of the spring. Some garage doors come with either 1 large torsion spring or 2 on each side making a total of 4 springs. It is never recommended for anyone to attempt the repair without experience and proper tools of a professional. If this is attempted, you are running a high risk of injury to your hand and fingers. Trust me, it is not worth it. (Google image: garage door spring repair injury ) When your garage door has more than one spring and one breaks or looses it's tension, it is recommended that you replace all of the torsion springs at once to prevent further damage to the garage door and it's components. Even though the garage door will function(if you decide to simply replace one), you may be running the risk of having the older springs break causing heavier load on the new spring and degrading its life span. In some extreme cases, garage door would drop without warning with no safety support, causing damage to the cables, panels, and the opener, not to mention what and who may be underneath it when the spring snaps. Save yourself the time and money, get them all replaced at once! It is recommended that you contact your local garage door repair company if you have any questions regarding spring or any other repairs to your garage door before you attempt them yourself.
