Installing Interior Door Casing: A Step-by-Step Guide

Installing interior door casing is a relatively straightforward project that can be completed in a few hours. By following these steps, you can ensure a professional-looking finish for your door. Before you begin, gather the following materials:

Door casing
Mitre saw
Brad nailer
Brad nails
Wood filler
Caulk gun
Painters tape

Step 1: Measure and Cut the Casing

Measure the width of the door frame and cut two pieces of casing to that length. Then, measure and cut two pieces of casing to the height of the door, minus the width of the top and bottom pieces. If you are using a mitre saw, set the saw to a 45-degree angle and cut the ends of the casing so that they will mitre together at the corners.

Step 2: Attach the Casing to the Door Frame

Place the top piece of casing on the door frame and secure it with brad nails. Then, place the side pieces of casing on the door frame and secure them with brad nails. Finally, place the bottom piece of casing on the door frame and secure it with brad nails.

Step 3: Fill the Nail Holes

Once the casing is attached, fill the nail holes with wood filler. Allow the wood filler to dry completely, then sand it smooth.

Step 4: Caulk the Casing

Apply a bead of caulk along the edges of the casing where it meets the wall. Use a damp cloth to smooth the caulk.

Step 5: Paint the Casing

If desired, you can paint the casing to match the wall or the door. Use painters tape to protect the wall and the door from paint spills.

Tips for Success

Use a sharp blade on your mitre saw to ensure clean, precise cuts.
Countersink the brad nails slightly below the surface of the casing.
Use a damp cloth to clean off any excess wood filler or caulk.
Allow the wood filler and caulk to dry completely before painting.

Conclusion

Installing interior door casing is a simple task that can add a touch of elegance to your home. By following these steps, you can achieve a professional-looking finish that will last for years to come.
