6. Do not force the pickets against the board. Instead, cut the new board at the point where it was last flush and make two boards (figure F). Cut at an angle, and make the cut so it falls in the center of a support post.

7. Install support board using 3-inch deck screws. Drill a pilot hole first, creating a pocket for head of deck screw and making it easier to drive in the screws.

8. Once all support boards are secure, use 2-inch wood screws to re-attach pickets.

9. Apply water seal to the new boards, give it about a week to dry then paint boards desired color.
