In a previous blog, we discussed the differences between pre-hung and slab doors. DIYers will have different approaches when it comes to choosing a door type. However, both door types require their own steps for installation. Here are all the steps you need to install a pre-hung door.

A Step-by-Step Process

1. Examine the floor: look over the floor to identify any areas where the floor is off-level.
2. Level the floor: if your floor is not level, then you should use shims to create a level floor.
3. Use a jigsaw to trim the door’s frame jamb: remove any packaging strips at the bottom of your jambs and then trim the high side of the jamb. Ensure your door jambs are at the proper heights.
4. Review your rough opening: install temporary cleats opposite of the door opening so they can hold your door frame. You want to center your jambs in this step as well.
5. Sit your door in the opening: place the door within the opening and shim the bottom of the door, so it fits snug in the opening. Check the door fits in the opening.
6. Shim and nail: shim the bottom of the door frame about 4 inches on the hinge side. Make sure the hinge side is completely plumb and then nail it.
   

   A level is an essential tool for installing a door.

7. Lock the strike side jamb: Use a shim to temporarily hold the strike side (door handle side) in the opening. You can nail or screw it to a stud.
8. Jamb and nail the strike side: add shims to the opening where the strike side does not meet flush. Then nail it into place.
9. Remove excess shims: using a box cutter or another knife, score the shim until the excess breaks away from the strike side.
10. Attach the trim: Nail the matching trim to the door frame. We recommend number 4 finish nails.
11. Set the door: Before fastening the door to the opening permanently, you should add temporary jambs in order to place the door flush in the opening.
12. Secure the door: Once the door is where you want it, nail the top corners. If you need to use shims to ensure the door is centered.
13. Check for a gap: test if the door opens and closes properly. The door should meet the doorstop all at once. If a portion of the door does not meet the stop, then you will need to add more shims.
14. Shim behind hinges: Slide shims behind the hinges’ screw holes. Fill the gap with the shims behind the hinges.
15. Screw the hinges: after adding shims behind the hinges, use long screws to keep them in place.
