Replace Interior Door Jamb: A Comprehensive Guide

Replacing an interior door jamb may seem like a daunting task, but with the right tools and guidance, it can be a straightforward and satisfying DIY project. This article provides a comprehensive guide to help you tackle this task with confidence.

Tools Required:

Pry bar or flathead screwdriver
Hammer
Circular saw
Miter saw
Measuring tape
Level
Shims
Nails or screws

Step 1: Remove the Old Jamb

Begin by removing the stop molding on both sides of the jamb using a pry bar or flathead screwdriver. Next, remove the casing, trim, and any other decorative elements. Use a hammer and a pry bar to carefully detach the jamb from the studs.

Step 2: Measure and Cut the New Jamb

Measure the height and width of the door opening. Cut four pieces of jamb stock to these measurements using a circular saw or a miter saw. For the head jamb, cut the angles on the ends where it will meet the side jambs.

Step 3: Install the Head Jamb

Place the head jamb in the center of the opening and level it. Nail or screw it into place. Use shims to level and plumb the jamb.

Step 4: Install the Side Jambs

Cut the side jambs to the desired length and cut angles where they will meet the head jamb. Install them on both sides of the head jamb, ensuring that they are plumb and flush with the head jamb.

Step 5: Install the Stop Molding

Cut the stop molding to the length of the jambs. Nail or screw it into place on the inside edge of the jambs. The stop molding should be flush with the edge of the jamb.

Step 6: Install the Casing and Trim

Finally, install the casing and trim around the jamb. These pieces should be nailed or screwed into place and will give the door a finished look.

Tips:

Use a level to ensure that all jambs and trim are installed plumb and square.
Use shims to ensure that the jambs are level and plumb.
Pre-drill holes before nailing or screwing to prevent splitting the wood.
Fill any gaps between the jambs and the studs with foam or caulk to prevent air leaks.
