How to Install a Prehung Interior Door With Trim

Installing a prehung interior door is a relatively easy project that can be completed in a few hours. With the right tools and materials, you can give your home a fresh, updated look. ### Tools and Materials You Will Need: * Prehung interior door * Door trim kit (including casing, architrave, and baseboard) * Measuring tape * Level * Pencil * Utility knife * Hammer * Nails or screws * Wood filler * Paint or stain (optional) ### Step 1: Measure the Doorway Before you purchase a prehung door, you need to measure the doorway to make sure it is the right size. Measure the width and height of the doorway, as well as the thickness of the door stop. Add 1/4 inch to the width and height measurements to allow for clearance. ### Step 2: Prepare the Doorway If you are replacing an existing door, you will need to remove it. To do this, use a pry bar to remove the nails or screws that are holding the door in place. Be careful not to damage the door frame. Once the door is removed, you will need to remove the old door stop. ### Step 3: Install the Door Jamb The door jamb is the frame that the door will fit into. It comes in two pieces, the jamb leg and the head jamb. To install the jamb leg, place it in the doorway and secure it with nails or screws. Make sure that the jamb leg is plumb and level. To install the head jamb, place it on top of the jamb leg and secure it with nails or screws. Make sure that the head jamb is level. ### Step 4: Install the Door Stop The door stop is a strip of wood that is installed on the door frame to prevent the door from swinging open too far. To install the door stop, measure the length of the door frame and cut the door stop to size. Place the door stop in the door frame and secure it with nails or screws. ### Step 5: Hang the Door To hang the door, lift it into the door jamb. Make sure that the door is centered in the doorway and that the top and bottom edges of the door are level. Secure the door to the jamb with nails or screws. ### Step 6: Install the Trim The trim is the molding that goes around the door. To install the trim, measure the length of the door frame and cut the trim to size. Place the trim around the door and secure it with nails or screws. ### Step 7: Finish the Door If desired, you can paint or stain the door and trim to match the rest of your home. ### Tips for Installing a Prehung Interior Door * Make sure that you measure the doorway carefully before you purchase a prehung door. * Be careful not to damage the door frame when you are removing the old door. * Use a level to make sure that the door jamb and door are plumb and level. * Secure the door to the jamb with nails or screws that are long enough to penetrate the door stop. * If you are painting or staining the door, be sure to use a paint or stain that is specifically designed for interior doors.
