With the damaged plank removed, you now need to install supports at either end of the opening for the new deck board.
- Using a circular saw (How To Use), cut two (2) 12" long sections of 2x4 support blocks.
- Take one of the 12" support blocks and place it centered under the opening alongside one of the joists and pulled hard to the underside of the deck boards.
- Nail the support block to the joist face with two (2) 3" spiral shank galvanized nails.
- Repeat this process for the other end of the opening, fastening the second support block to the other joist face in the same manner.
