How to Install a Prehung Interior Door with Split Jamb

Replacing an interior door with a prehung unit is a relatively straightforward project that can be completed in a few hours. A prehung door comes with the door, frame, and hinges already assembled, making the installation process much easier. Here's a step-by-step guide on how to install a prehung interior door with split jamb:

Materials you'll need:

Prehung interior door
Shims
Level
Drill
Screws
Hammer
Nail set
Trim kit (optional)

Step 1: Remove the old door

Start by removing the old door from the frame. Use a screwdriver to remove the hinges from the door and frame. Then, gently lift the door out of the frame.

Step 2: Prepare the opening

Once the old door is removed, inspect the opening for any damage or unevenness. If necessary, use a hammer and chisel to level the opening and remove any obstructions.

Step 3: Install the jamb

Place the prehung door into the opening and align it so that it is level and centered. Use shims to level the door and ensure that it swings freely without rubbing against the frame.

Step 4: Secure the jamb

Once the door is level and aligned, secure the jamb to the framing with screws. Use at least two screws on each side of the jamb.

Step 5: Install the door

Lift the door back into the frame and align it with the hinges. Use a nail set to tap the hinge pins into place. Make sure that the door opens and closes smoothly.

Step 6: Install the trim (optional)

If desired, you can install a trim kit around the door to give it a finished look. Trim kits are available in various styles and materials to match your décor.

Tips:

Make sure that the rough opening is square and level before installing the door.
Use plenty of shims to ensure that the door is level and swings freely.
Do not overtighten the screws when securing the jamb.
If the door is not swinging properly, adjust the hinges by loosening or tightening the screws.
Caulk around the perimeter of the door frame to seal any gaps.

By following these steps, you can easily install a prehung interior door with a split jamb. This project is a great way to update the look of your home and improve the functionality of your door.
