It’s tough to know when you’re garage door needs to be replaced or simply repaired if you are not experienced in this sort of thing. If you or someone you know has backed into your garage door and damaged it to the point of its functionality being affected, it is time to replace. This is due to the fact that not only has your garage door/panels been damaged, but most likely the hardware has been as well. When a collision occurs, it bends the frame and supporting rails, which are all replaced when a new door is installed. Trying to replace a single panel requires only for the panel to be replaced and leaves other parts that were most likely affected during the accident still in place, which very well may cause problems in the very near future.
