If you look at the upper right section of this garage door, you will notice the skin of the panel is separating from the stile. This occurs when a c – channel is incorrectly installed on the top of the door. They’re many garage door guys locally, but this is usually what you get when you hire the one unlicensed man in a truck. Once the job is complete, you can bet you won’t see the installer again for a warranty issue. To avoid this and to protect yourself, call a reputable licensed company like A plus.
