Introduction

This guide explains how to reattach a vent cover if the original screw hole is too worn out to be re-used, or was incorrectly placed originally.

Typically, a vent cover attaches directly to a hole in the ductwork so that the drywall doesn't wear out during the process. Check to confirm this isn't an option before starting this procedure, as the vent will cover minor drywall issues and connecting to the duct work directly will save substantial time.

Measure and mark a rectangle around the damaged drywall area using the carpenter's pencil.
Set up a drop cloth underneath the work area, and a step ladder on top of the cloth for cleanliness and easy access to the work space as needed.
Wear goggles throughout this process. This work will result in drywall dust and insulation falling frequently, in addition to the risks of dropped tools.

Put the patch into place.

Drill holes through the patch and furring strips.
Using the holes drilled as guides, insert wood screws to attach the patch to the furring strips.
