Here’s a great tip from ApartmentTherapy for getting a little more life out of a stripped-out, too-lose screw-hole in wood: line the hole with toothpicks and replace the screw:
Taking my father’s advice, I unscrewed the hinge and placed a few pieces of toothpick in the screw hole. As I reinstalled the screw, I could feel that the toothpick pieces were doing their job. Basically the screw is able to grip onto the soft wood of the toothpick pieces, which creates a tight fit that couldn’t be achieved in the stretched and stripped hole.
