The author also discusses how to build better homes by building better homes by building better doors.

To flash an exterior door, the author first reads the installation instructions provided by the door manufacturer. If these instructions violate basic flashing principles, they should be followed. The article then guides the reader through the process of replacing exterior door trim, from removing old trim to installing new PVC components.

The author suggests unscrewing the threshold, taking out the old flashing, sliding a new piece of slashing under the door, replacing the threshold, and re-calking everything. The author begins with the side flashing and head flashing, installs the handle and other hardware, and air-seals the door. To install the flashing, cut pieces of building paper and self-adhesive flashing to fit and install them in the correct order (bottom, sides, and top).

By using flashing material around the sill, header, and doorjambs, a watertight seal can be created, preventing all the door openings from opening.
