You know that you need to call Pro Garage Doors to repair your springs, when:
The door is crooked. One of the springs is broken and all the weight falls on the other one.
The garage door opens and closes with a banging noise instead of a smooth and steady closing.
The door opens only partially. The springs don’t function properly, and the weight of the door falls on the garage door opener, which can’t withstand the weight and can suffer damage too.
