Step 1: Measure the Doorway

Use a tape measure to determine the width and height of the doorway. Make sure to measure at multiple points to ensure an accurate measurement.

Step 2: Remove the Old Door (if applicable)

If you are replacing an existing door, you will need to remove it before installing the new one. To do this, use a utility knife to score around the caulk seal between the door jamb and the wall. Then, use a pry bar to gently pry the door jamb away from the wall. Be careful not to damage the wall or the door jamb.

Step 3: Prepare the Doorway

Once the old door is removed, you need to prepare the doorway for the new one. This may involve removing any old weatherstripping or shims. You may also need to make adjustments to the door jamb to ensure that it is level and plumb.

Step 4: Install the Split Jamb

The split jamb consists of two pieces of wood that are connected by hinges. To install the split jamb, position it in the doorway and use a level to make sure that it is plumb. Then, use a drill to make pilot holes for the nails. Secure the split jamb to the wall using nails or screws.

Step 5: Hang the Door

Once the split jamb is installed, you can hang the door. To do this, lift the door into the jamb and align the hinges with the hinge plates. Then, use a Phillips head screwdriver to secure the hinges to the hinge plates.

Step 6: Add Weatherstripping and Caulk

To ensure a weathertight seal, apply weatherstripping to the door jamb and the door itself. You can also caulk around the edges of the door jamb to prevent air and moisture from leaking in.

Step 7: Paint or Stain the Door (if desired)

If you want to paint or stain the door, now is the time to do it. Be sure to use a paint or stain that is specifically designed for interior doors.

Step 8: Enjoy Your New Door!

Once the paint or stain has dried, you can enjoy your new interior door. The new door will add beauty and value to your home, and it will also improve the energy efficiency of your home.
