How To Install Interior Door Jamb

Installing an interior door jamb is a relatively straightforward project that can be completed in a few hours. By following these step-by-step instructions, you can ensure that your new door is installed correctly and securely.

Materials Needed:

Interior door jamb
Door stop molding
Casing molding
Shims
Nails or screws
Hammer or nail gun
Caulk gun
Caulk

Step-by-Step Instructions:

Step 1: Prepare the Doorway

Begin by removing the old door and jamb. If the old jamb is in good condition, you may be able to reuse it. However, if it is damaged or rotted, you will need to replace it with a new one.

Step 2: Install the Jamb

Place the jamb in the doorway and shim it around the edges until it is plumb and level. Use a level to ensure that the jamb is vertical and a straightedge to ensure that it is horizontal.

Step 3: Nail or Screw the Jamb

Once the jamb is in place, nail or screw it to the framing of the doorway. Use 2-inch nails or screws, and space them 12 inches apart.

Step 4: Install the Door Stop Molding

The door stop molding is installed on the inside edge of the jamb. It helps to keep the door from swinging open too far.

Step 5: Install the Casing Molding

The casing molding is installed on the outside edge of the jamb. It helps to cover the gap between the jamb and the wall, and it gives the door a finished look.

Step 6: Caulk the Jamb

Once the casing molding is installed, caulk the gap between the jamb and the wall. This will help to seal out air and water, and it will give the door a more professional look.

Step 7: Install the Door

Hang the door on the jamb and make sure that it opens and closes smoothly. If the door is not hanging properly, adjust the shims until it does.

Step 8: Finish the Trim

Once the door is installed, you can finish the trim by adding baseboards, crown molding, or other decorative elements.

Tips:

If you are unsure about how to install an interior door jamb, consult with a professional.

By following these step-by-step instructions, you can install an interior door jamb like a professional. With a little time and effort, you can give your home a new look that you will love for years to come.
