Just about everyone knows to apply light penetrating oil or silicone spray to the hinges. But to really rid your door of squeaks, use your hammer and pry bar to lift the hinge pins up an inch or so. Apply the oil or spray to the top of the hinge, then wait a minute or two before you tap the pin back in place.
Weatherstrip and caulk all cracks between the wall and the window trim, especially under the window sills. Replace broken glass and putty any loose window panes. Caulk around the moving parts of windows with a strip-away, non-permanent caulk during the winter. This type caulk can be removed easily in the spring.
