Step-by-Step: Replacing Interior Door Slab

This guide assumes your existing door frame is in good condition. If not, skip to the “Door Frame Replacement” section.

Step 1: Measuring the Existing Door

1. Width: Measure the width of the door at the top, middle, and bottom. Use the largest measurement.
2. Height: Measure the height of the door on both sides. Use the largest measurement.
3. Thickness: Measure the thickness of the door. This is usually 1 3/8 inches for interior doors.

Step 2: Removing the Old Door

1. Protect the Area: Place a drop cloth or old blanket beneath the door to protect the floor.
2. Remove the Doorknob: Unscrew and remove the doorknob and any associated hardware.
3. Loosen the Hinges: Use a screwdriver to loosen the screws on the top hinge first. This will help prevent the door from binding as you remove the other screws.
4. Remove the Hinge Pins: Use a hammer and a nail set to gently tap out the hinge pins, working from the bottom up. You can also use a screwdriver and hammer.
5. Remove the Door: Carefully lift the door away from the frame. You might need a helper for heavier doors.

Step 3: Preparing the New Door Slab

1. Compare the New Door: Place the new door next to the old door. Ensure the new door matches the size of the old door.
2. Mark Hinge Locations: Lay the old door on top of the new door. Trace the locations of the hinges.
3. Mark Doorknob Location: Mark the location of the doorknob. Use a hole saw or drill to create the hole for the doorknob.

Step 4: Cutting Hinge Mortises on the New Door

1. Score the Outline: Using a utility knife, score the outline of the hinge mortises on the new door. This prevents splintering.
2. Chisel the Mortises: Use a chisel and hammer to carefully remove the wood within the scored lines, creating a shallow recess for the hinges. Aim for a depth that matches the thickness of the hinge.
3. Test the Fit: Place the hinges in the mortises to ensure they fit flush with the door surface. Adjust as needed.

Step 5: Hanging the New Door

1. Attach Hinges to the Door: Screw the hinges to the door, aligning them within the mortises.
2. Position the Door: Carefully position the new door in the frame.
3. Attach Hinges to the Frame: Align the hinges on the door with the hinge plates on the frame. Insert the hinge pins. Start with the top hinge.
4. Check the Fit: Open and close the door to check for proper alignment. If the door binds or sticks, use wood shims to adjust the frame.

Step 6: Installing the Doorknob and Strike Plate

1. Install the Doorknob: Follow the manufacturer’s instructions to install the doorknob.
2. Mark the Strike Plate Location: Close the door and mark the location where the doorknob latch hits the frame.
3. Install the Strike Plate: Chisel out a recess for the strike plate and screw it into place.

Step 7: Finishing Touches

1. Fill Imperfections: Use wood filler to fill any nail holes or imperfections.
2. Sand Smooth: Sand the filled areas smooth.
3. Prime and Paint: Prime and paint the door to match your décor. Apply multiple coats for best results.
