Last January I purchased a bi-level built in 1979.
The garage door is a double-wide, using a powered opener.
When the door is in the closed position, only the middle touches the floor, with the ends having a gap of 1 - 2" between the floor and the bottom of the door.
I have loosened & re-tightened all the door connector brackets in an effort to level the door in the closed position, but when I operated the door again the situation didn't change.
Is there a way to remedy this in liu of replacing the door?
