Drill a hole at the center of each end of the board you are replacing with a 1/2-inch arbor hole saw. Drill the hole 2 inches from each end so you do not hit the joist under the board.
Insert the blade of your jig saw in the holes and cut across the board at one end. Cut the other end of the board off while a friend holds the board from falling. Remove the cut portion of the board.
Slide a crowbar between the deck joists and remaining ends of the board. Push down on the crowbar to raise to pry the board nails up and remove the ends from each joist.
Things You Will Need
- 1/2-inch arbor hole saw
- Jig saw
- Pry bar
- You can insert the crowbar between the ends of the bad board and good boards. Place a block of scrap wood on top of the end of the good board to provide leverage for the crowbar and protection for the good board. Pry the old board up to remove it from the deck.
