Door feels heavy
A garage door should not suddenly feel like dead weight. If it does, one of the most common causes is a failed spring. Springs are what counterbalance the weight of the door. When one breaks, the door can feel far heavier than normal. That is a strong sign you may need garage door spring repair.
Door will not open
If the opener runs but the door does not go up, or it starts and stops, the spring may no longer be balancing the door. Continuing to hit the button can strain the opener. This is one of the most common broken spring repair calls we get.
Loud bang from garage
Many homeowners describe a broken spring as sounding like a gunshot or a sharp bang in the garage. If you heard that sound and the door stopped working afterward, a snapped spring is a likely cause.
