Steps 6 - 10

6. Shim the bottom of the door frame up about 4 in. from the floor on the hinge side, making sure the hinge side is exactly plumb, and then nail it. Tape your level to a straight 2x4 as shown. Next, shim the center area of the jamb to straighten it and then nail it. Check the whole length with your straightedge.

7. Tack a 4-in. 1x2 to the front edge of the jamb with a 4d finish nail. Set up an even 3/16-in. gap between the door and the strike-side jamb. Then screw the block to the studs to hold the jamb in this position.

8. Shim and nail the strike side near the strike plate and then near the floor.


9. Score the shims several times with a sharp blade and then snap them off to make way for the trim.

10. Nail the trim to the door frame with No. 4 finish nails. Nail the trim to the framing with No. 6 finish nails.
