My garage door has several problems…it’s totally off kilter from ‘adjustments’ a well-meaning relative did (he almost killed himself in the process!) ….about a third of the door is rotten or has water damage and termite damage (termites are taken care of, now!)…based on this information, is it best to have the rotted sections replaced and the balance reset, or just to go ahead and get a new garage door installed and what would that cost in general?
