Have you checked the spring on your garage door ?
SAFETY TIP: Beware of old springs. Keep in mind that garage door springs are tightly wound and under high tension. Eventually, all springs will wear out and break. A breaking spring that is not properly contained could lash out and strike property or people. If you have an older garage door, be certain your springs are inspected and replaced by a professional installer if needed. If your door has two springs, replace both, even if one is not broken. This will not only prevent any damage caused by the breaking of the second spring, but also keep your door working efficiently. The labor cost of a second call can be avoided by replacing both garage door springs at the same time (the labor to change 1 or 2 springs at the same time is the same).
