How to Install Prehung Interior French Doors

Installing prehung interior French doors can add a touch of elegance and sophistication to any home. By following these detailed instructions, you can complete this project successfully, even as a novice DIYer.

Materials and Tools:

Prehung French door unit
Level
Measuring tape
Pencil
Shims
Screws
Power screwdriver
Caulk
Caulk gun

Step-by-Step Instructions:

1. Remove the Old Door (if applicable):

If replacing an existing door, start by unhinging it and removing any molding around the frame. Use a pry bar to gently lever the old frame out of place.

2. Prepare the Doorway:

Measure the doorway to ensure that the prehung door unit will fit snugly. Level the floor and ensure the walls are plumb. If necessary, adjust the framing to accommodate the new door.

3. Position the Prehung Door:

Place the prehung door unit in the doorway and align it level using shims. Adjust the shims until the door is plumb and square.

4. Secure the Door Frame:

Use screws to secure the door frame to the studs in the wall. Start by driving a screw through the hinge side jamb and into the stud. Continue adding screws along the top jamb and the opposite jamb.

5. Install the Door Hinges:

Attach the door hinges to the frame and the door leaf. Use screws to ensure a secure connection. Check that the door opens and closes smoothly.

6. Install the Lockset and Handles:

Mark the location of the lockset and handles on the door and bore the necessary holes. Install the lockset and handles according to the manufacturer's instructions.

7. Trim and Caulk:

Cut the molding to fit around the door frame and install it using nails or adhesive. Apply caulk around the edges of the door frame and molding to seal any gaps.

Tips for Success:

Use a level regularly to ensure accuracy throughout the installation process.
Drive screws at an angle to increase their holding power.
Do not overtighten screws, as this can damage the door frame.
Allow sufficient time for the caulk to cure before using the door.

Installing prehung interior French doors is a rewarding project that can significantly enhance the look and feel of your home. By following these instructions carefully, you can complete the task with confidence and precision.
