There are many parts to a garage door that can become broken or fail you if you do not keep up with them over time. One of these parts being the springs. Over time springs wear out, and fatigue. They will no longer have the ability to correctly counter balance the weight of the garage door. During this period your door will become heavier and heavier. Sadly, when you have a broken spring, this has been taking place for the last couple of months or years!
