How to Install an Exterior Prehung Door
Installing an exterior prehung door is a task that many homeowners can undertake themselves, saving both time and money. Prehung doors come with the door frame already attached, making the installation process much simpler than installing a door from scratch. In this article, we will guide you through the steps to install an exterior prehung door successfully.
Step 1: Preparing the Installation Site
Before you begin, ensure that the installation site is ready. This means removing the old door, if applicable, and cleaning the area where the new door will be installed. Check for any unevenness or damage to the door frame and make necessary repairs.
Step 2: Measuring the Door Opening
Accurate measurements are crucial for a successful installation. Measure the width and height of the door opening to ensure that the prehung door you have purchased will fit properly. It’s essential to have the door slightly smaller than the opening to allow for weather stripping and to prevent water and air infiltration.
Step 3: Removing the Old Door (if applicable)
If you are replacing an existing door, you will need to remove it. Begin by removing the door from the hinges, then remove the door frame. Be sure to take note of the placement of any trim or molding, as you will need to reinstall it later.
Step 4: Installing the Door Frame
Position the prehung door frame in the opening. Make sure it is level and plumb using a level. Secure the frame to the rough opening using screws. You may need to use shims to ensure a level and square installation.
Step 5: Installing the Door
Once the frame is secure, slide the door into the frame. Make sure it is aligned correctly and fits snugly. Secure the door to the frame using the provided hinges. Tighten the screws, but be careful not to overtighten, as this can damage the door.
Step 6: Adjusting the Door
Adjust the door to ensure it opens and closes smoothly. You may need to adjust the hinges or the door itself to achieve the desired fit. Check for gaps around the door and add weather stripping if necessary.
Step 7: Installing Trim and Molding
Reinstall any trim or molding that was removed during the installation process. This will help to seal the door and improve its appearance. Make sure the trim is level and securely fastened.
Step 8: Final Touches
Inspect the entire installation, including the door, frame, and trim, to ensure everything is in place and functioning correctly. Clean up any debris and enjoy your new exterior prehung door.
Installing an exterior prehung door can be a rewarding DIY project. By following these steps, you can install your new door with confidence and enjoy the benefits of a fresh, secure entryway.
