    Set a hydraulic jack and post under the beam, and jack up the joists about 1/8 in. a day until they're level. Jacking them up too fast may cause cracks in the walls and floors overhead. If a crack or sag is isolated to one area, the sister joist should extend at least 3 ft. on both sides of the problem area.
