Installing a Prehung Interior Door: A Step-by-Step Guide

Installing a prehung interior door can enhance the functionality and aesthetic appeal of your home. With careful planning and precise execution, this project can be completed successfully. Here's a comprehensive guide to walk you through the essential aspects of installing a prehung interior door:

1. Preparing the Doorway

Before you begin, it's crucial to prepare the doorway. Remove the existing door and door frame, if any. Ensure that the rough opening is square and plumb by measuring diagonally from corner to corner. The measurements should be equal, and the opening should be level and vertical. If necessary, make adjustments to the rough opening using a saw or shims.

2. Installing the Door Frame

Position the door frame in the rough opening and secure it temporarily using shims. Ensure that the frame is plumb and level. Use a level to check both sides of the frame and adjust the shims accordingly. Once the frame is level, nail it securely into the studs.

3. Hanging the Door

Lift the prehung door into the frame and align the hinges with the corresponding hinge plates. Slide the door into place, ensuring that the hinges are fully engaged. Use a level to check the door's alignment, and make adjustments as needed. Secure the hinges with screws.

4. Installing Casing

Trim the casing to fit the door frame. Miter the corners and attach the casing around the frame using nails or an adhesive. Fill any gaps between the casing and the wall using caulk.

5. Finishing Touches

Paint or stain the door and casing to match the existing décor. Install doorknobs or handles, and make sure the door opens and closes smoothly. Test the door to ensure that it functions properly and does not bind or scrape against the floor or frame.
