Install Prehung Interior Doors: A Step-by-Step Guide

Installing prehung interior doors is a cost-effective and efficient way to upgrade your home's decor. With a little preparation and the right tools, you can complete this project in a day or two. Here's a comprehensive guide to help you through each step.

Materials and Tools You'll Need:

Prehung door
Drill
Screwdriver
Level
Hammer
Pry bar
Shim
Caulk

Step 1: Prepare the Doorway

Remove the old door and frame. Square off the opening using a level and a saw. Measure the opening and ensure the prehung door will fit snugly.

Step 2: Position the Door

Lift the prehung door into place and set it in the opening. Use shims to level and align the door. Ensure the door swings freely without hitting the frame.

Step 3: Secure the Door

Screw the door frame into the studs of the wall. Start at the top and work your way down. Ensure the screws are tight but avoid overtightening.

Step 4: Install the Trim

If the prehung door came with trim, nail or glue it in place. Measure and cut the trim to fit around the door opening. Use a level to ensure straight lines.

Step 5: Caulk and Seal

Apply caulk around the edges of the door frame and trim. Smooth the caulk with your finger or a damp cloth. Allow the caulk to dry and cure completely.

Tips:

Use a level throughout the process to ensure accuracy.
Shims are essential for leveling and aligning the door.
If the door is too loose, insert more shims or tighten the screws.
For a professional finish, use quarter-round molding to cover the gaps between the trim and the wall.
Check the door hardware regularly and adjust as needed.

Congratulations! You have successfully installed a prehung interior door. With a little care and maintenance, it will provide years of service.
