Step-by-Step Guide

1. Prepare the Doorway

Before installing the door jamb, ensure that the doorway is square and plumb. Use a level and tape measure to check the height, width, and squareness of the opening.

2. Assemble the Door Jamb

Locate the three sections of the door jamb kit (head jamb, two side jambs). Lay them on a flat surface and join them together using trim nails. Make sure the corners are at a 90-degree angle.

3. Install the Head Jamb

Place the head jamb across the top of the doorway and level it using a level. Secure it to the header using framing nails or a nailer.

4. Install the Side Jambs

Insert the side jambs into the slots on the head jamb. Align them vertically using a level and secure them to the studs using trim nails.

5. Check for Squareness

Once the jamb is installed, check its squareness using a level or a carpenter's square. Adjust the jamb as necessary until it is perfectly square.

6. Fill and Caulk

Use wood filler to fill any nail holes or gaps in the jamb. Once the wood filler dries, apply a thin bead of paintable caulk around the perimeter of the jamb, where it meets the drywall or wall.

7. Install the Door

With the jamb securely installed, you can now hang the door. Align the door hinges with the hinge slots on the jamb and secure them using screws.

8. Finish

Once the door is installed, paint or stain the door jamb to match the surrounding trim and walls.

Tips for Success

Wear safety glasses throughout the installation process.

Measure carefully and check for squareness at every step.

Use nails that are long enough to penetrate the studs securely.

Apply caulk generously to prevent air leaks and moisture damage.

Allow ample time for the wood filler and caulk to dry before painting or staining.

Conclusion

By following these steps and tips, you can successfully install an interior door jamb that will enhance the appearance and functionality of your home. Remember, proper installation is crucial to ensure the durability, security, and smooth operation of your door for years to come.
