How To Replace Interior Door Casing

How to Replace Interior Door Casing

Replacing interior door casing can be a relatively simple task that can give your home a fresh, updated look. Here is a step-by-step guide on how to do it:

Step 1: Remove the Old Casing

Start by removing the old casing around the door. Use a pry bar or a flathead screwdriver to gently pry the casing away from the wall. Be careful not to damage the wall or the door frame.

Step 2: Cut the New Casing

Measure the length of the casing you need to replace and cut the new casing to size using a miter saw. If you don't have a miter saw, you can use a handsaw and a miter box to cut the angles.

Step 3: Install the New Casing

Apply a thin layer of construction adhesive to the back of the new casing and press it into place around the door frame. Use a nail gun or a hammer and nails to secure the casing in place. Make sure to countersink the nails slightly so that they are flush with the surface of the casing.

Step 4: Fill the Nail Holes

Once the casing is installed, fill the nail holes with wood filler. Use a putty knife to apply the wood filler and smooth it out. Allow the wood filler to dry completely.

Step 5: Sand and Paint

Once the wood filler is dry, sand the casing smooth using a fine-grit sandpaper. Then, paint the casing to match the rest of the trim in your home.

Step 6: Install the Trim

If you are adding trim to the casing, now is the time to do it. Cut the trim to size and miter the corners. Apply a thin layer of construction adhesive to the back of the trim and press it into place around the casing. Secure the trim with nails or screws.

Additional Tips

Use a level to make sure that the casing is installed straight.
If you are replacing the casing around a door that has a threshold, be sure to cut the casing so that it fits snugly against the threshold.
If you are not comfortable replacing the casing yourself, you can hire a professional to do it for you.
