Installing a new door can enhance the aesthetic appeal, functionality, and security of your home. While it may seem like a challenging task, with the right tools and guidance, you can successfully install a new door yourself. In this comprehensive guide, we will walk you through the step-by-step process of installing a new door, helping you achieve a professional-looking result and save money on hiring a contractor.
Before you begin the installation process, gather all the tools and materials you’ll need. These typically include a new door and frame, a level, a tape measure, a saw, a screwdriver or drill, screws, shims, a pencil, and a hammer. Ensure that the new door and frame are the correct size and style for your specific needs.

Start with the Old Door
Start by removing the old door and frame. Begin with the door by unscrewing the hinges and carefully lifting it off the frame. Next, remove any trim or molding surrounding the frame. Use a pry bar or hammer to gently remove the frame, taking care not to damage the surrounding walls.
Once the old door and frame are removed, prepare the opening for the new door. Measure the width, height, and depth of the opening to ensure the new door and frame will fit properly. Use a level to ensure the opening is plumb and square. If necessary, adjust the opening by adding shims to create a level surface. Trim any excess shims to fit snugly.
Time for a New Door
With the opening prepared, you can now install the new door frame. Position the frame in the opening and use shims to ensure it is level and plumb. Insert shims between the frame and the opening, adjusting as needed until the frame is secure and properly aligned. Secure the frame with screws, ensuring they penetrate both the frame and the wall studs. Trim any excess shim material.
With the frame in place, you can now hang the new door. Carefully lift the door and align the hinges with the hinge recesses on the frame. Insert the hinge pins or screws to secure the door to the frame. Test the swing of the door to ensure it opens and closes smoothly. Use a level to adjust the position of the door, adding shims as necessary to create an even reveal around the frame.

To complete the installation, attach the door handle, lockset, and any other hardware included with the door. Follow the manufacturer’s instructions for proper installation. Once all the hardware is installed, check the door’s operation and make any necessary adjustments. Apply a coat of paint or stain to the door and frame if desired. Finally, add trim or molding around the frame to enhance the finished appearance.
By following these step-by-step instructions, you can confidently install a new door and transform the look and functionality of your home. Remember to take your time, use the appropriate tools and materials, and prioritize safety throughout the process. With patience and attention to detail, you can achieve a professional-quality installation and enjoy the benefits of a new door.
