Before You Begin
While installing a door is a job most DIYers can handle, it typically requires two people, as even the lightest interior prehung doors weigh more than 50 pounds. With that in mind, you’ll need an extra set of hands to hold the door frame in place while you install the shims, level the frame, and install the fasteners.
STEP 1: Remove the prehung door from the frame
Remove the pins in the hinges with a nail set and hammer, then pull the door out of the frame. Set the door aside and place the frame inside the rough opening about where it should be positioned. Make sure the side jambs and head jamb are even with the wall on both sides and the top to allow for the installation of molding later on.
STEP 3: Adjust the shims so the door is plumb and level
Using the level, check the entire frame, including the interior and edges of the jamb, to make sure it’s properly aligned inside the rough opening. Make adjustments to the shims until the door is level and plumb. Double-check to make sure the door jambs are flush with the rough framing to allow for the installation of the door trim.
STEP 4: Secure the door shims with screws
Fasten the door jamb to the rough framing with 3-inch screws, using a cordless hammer drill equipped with a Phillips-head screwdriver bit. Make sure to drive the screws all the way through the jamb and the shims and into the rough framing. Each screw must penetrate a door shim.
STEP 5: Reinstall the door and trim
If you’re replacing an existing door, reattach the trim around the door frame, covering the gap between the rough carpentry and the door jamb. If you’re installing a door on a new doorway, you’ll need to use a chop saw or miter box to cut new trim to size to fit around the doorway.
Final Thoughts
By following the steps in this door shimming guide, you can ensure a successful installation of a new door or the reinstallation of an existing one. Keep in mind that once the door is installed, it may rub against the frame when it opens and closes. This doesn’t mean the door jamb installation was completed incorrectly.
