I recently tiled my backsplash but when I put the receptacles back, I noticed some of the screw holes on the electrical box are broken off or missing. Old owners probably epoxyed the holes together but I broke them when I removed the receptacles. I can't remove the boxes without tearing down the backsplash. Is there a way to add the screw holes back somehow? via /r/DIY http://ift.tt/2oFvv7D
