Install exterior prehung door: Step-by-step guide to successfully installing a prehung exterior door

Installing an exterior prehung door can be a rewarding DIY project that enhances your home's curb appeal and energy efficiency. A prehung door comes with the door already attached to the frame, making it easier to install compared to traditional doors. Follow this comprehensive guide to ensure a successful installation.**Step 1: Gather Your Tools and Materials**Before starting, gather the necessary tools and materials, including a level, hammer, pry bar, tape measure, screwdriver, shims, and wood screws. You’ll also need a prehung exterior door, which can be purchased at most home improvement stores.**Step 2: Remove the Old Door**If you're replacing an old door, begin by removing it. Unscrew the hinges using your screwdriver, then carefully take the door off the frame. Use a pry bar to remove the old door frame if necessary, ensuring you do not damage the surrounding walls.**Step 3: Prepare the Door Opening**Clean the door opening of any debris or old materials. Measure the width and height of the opening to ensure your new prehung door will fit perfectly. Make any adjustments if necessary.**Step 4: Position the New Door**With the help of a friend, place the new prehung door into the opening. Ensure that the door is level and plumb by using your level. Adjust the door as necessary by placing shims under the frame until it is perfectly aligned.**Step 5: Secure the Door Frame**Once the door is level, use wood screws to secure the frame to the wall studs. Start at the top and work your way down, adding screws to both the left and right sides of the frame. Make sure to check the level after each screw to maintain alignment.**Step 6: Install the Trim**After the door is securely in place, it’s time to install the trim around the door frame. This can be done using finishing nails and a hammer. Ensure that the trim is flush with both the frame and the wall for a polished look.**Step 7: Test the Door**Open and close the door a few times to ensure it operates smoothly. Check for any gaps between the door and frame. If you notice any issues, adjust the shims and screws as needed.**Step 8: Finish Up**Finally, apply weather stripping around the door frame to improve energy efficiency. This will help keep out drafts and moisture, enhancing the longevity of your door. Paint or stain the door as desired to complete the look.By following these steps, you can successfully install your new exterior prehung door and enjoy the benefits of improved aesthetics and energy efficiency in your home. Happy DIYing!
