Fixing Loose Joints
Before embarking on bigger repairs, check to see if your opening frame has loose joints that can be easily repaired with dowels. If they're loose, simply cramp the frame together and drill two holes through the joint - making sure the drill bit passes all the way through the frame. The holes must be the same diameter as the dowels. Smear glue on the dowels and hammer into the holes. Leave to dry overnight, trim the tops and sand smooth. Paint.
