I have a ceiling vent where the drywall is cut a bit larger than the actual vent. I was looking for some advice on the repair.
The duct is mounted to a stud along the top (a piece of the stud is visible in the top right). Should I cut a slightly larger square (around the vent cover) and add a piece of backing on the bottom side so I have something to screw the patch into on the top/bottom? Or should I cut a larger section of drywall out so I can catch the stud on the bottom. The vent cover itself is about 8 inches.
