Preparing the Doorway Opening
Before installing an exterior door, it’s crucial to ensure that the doorway opening is adequately prepared. This involves a series of precise measurements and meticulous steps to create a sturdy and airtight frame for the new door.
Measuring the Opening
Using a measuring tape, carefully determine the width and height of the doorway opening. Measure the width at three different points: the top, middle, and bottom. Record the smallest of the three measurements as the actual width. Similarly, measure the height at three different points: the left, center, and right sides. Again, record the smallest measurement as the actual height.
It’s important to account for any existing trim or molding around the doorway opening. Measure the thickness of the trim and subtract it from both the width and height measurements to determine the rough opening size.
Framing the Opening
The rough opening size should match the dimensions of the new door frame. If any adjustments are necessary, use a circular saw or reciprocating saw to cut and shape the framing members accordingly.
To ensure a level and square opening, use a level and framing square to check the vertical and horizontal alignment of the framing members. Secure the framing with nails or screws, ensuring a tight and sturdy construction.
Installing a Weather Barrier
To prevent air and moisture from infiltrating the doorway, install a weather barrier around the perimeter of the rough opening. This can be a self-adhesive membrane or a roll of house wrap. Overlap the seams and secure the weather barrier to the framing with staples or tacks.
Installing the Exterior Door Frame
The door frame, also known as the jamb, is the structure that supports and surrounds the door. Installing it properly is crucial for a secure and weather-tight installation.
1. Prepare the Rough Opening
Before installing the frame, ensure the rough opening (the space in the wall where the door will be installed) is level, square, and plumb. Use a level and square to check for accuracy and make adjustments if necessary.
2. Install the Side Jambs
Position the left and right side jambs into the rough opening, aligning them with the exterior siding. Secure them with galvanized nails or screws, ensuring the jambs are flush with the wall’s interior surface. Use shims to level and plumb the jambs if needed.
3. Install the Header
The header is the top horizontal member of the door frame. To install it:
- Place the header on top of the side jambs, aligning it with the top of the rough opening.
- Install temporary supports (e.g., 2x4s) to hold the header in place.
- Ensure the header is level and plumb using a level and square.
- Secure the header to the side jambs with galvanized nails or screws.
- Remove the temporary supports and nail or screw the header securely to the rough opening framing.
