When replacing screening in wooden frames, you may discover some problems with the frame itself. Wood shrinks, warps, and moves, so joints often come loose.

Loose joints on wooden frames can easily be reinforced with fasteners, angle plates or screws.

Pry up the screen molding with a small chisel or screwdriver. If the molding is sealed with paint, use a utility knife to cut the paint film and free the molding.

Stretch the new screen fabric tightly across the frame and hold it in place with staples or thumbtacks. It usually works well to leave extra screen overhanging the frame so you can pull it tightly before stapling. Then simply trim the overhang once it is secured.

Nail the screen molding back in place with wire brads. Cut away the excess screen fabric with a utility knife.
