Step 5 · Install Door Casing and Trim

Measure and cut casing trim pieces to fit around the exterior of the door jamb. Miter the corners for a clean, professional look. Apply a small bead of construction adhesive to the back of the casing if desired, then nail the casing into place along the jamb and the wall studs using finishing nails. Ensure the nails are set slightly below the surface for easy filling.
