How to Replace a Broken Front Porch Board
Ask This Old House general contractor Tom Silva fixes a front porch by replacing a deck board
- To avoid damaging the surrounding boards, pull out the nails in the board using a hammer and a cat’s paw. For stubborn nails, use nail-pulling pliers.
- Once the nails are out, use a pry bar to go under the board and pull it up. Wiggle it out delicately as to not harm any other boards.
- Cut the 1x4 fir board to length to match the length of the other deck boards using a miter saw or circular saw.
- Depending on the porch, you may be able to just lay the board in place. However, in this case, a door threshold and a solid porch railing system prevent that.
- To remedy that, cut the 1x4 fir board a little shorter. Then create a shelf for the board to sit at one end using an old piece of deck board.Use construction adhesive to attach the shelf to the underside of the surrounding deck boards.
- Secure the shelf to the adjacent deck boards further with a trim head screw.
- Get an exact measurement for the new board and cut the board to length using a miter or circular saw.
- Apply construction adhesive to the ledger board and the new shelf board. Then, set the decking into place, avoiding a visible joint.
- Nail the board down using 8d finish nails and a hammer.
- Make sure all the nails are below the wood surface using a nail set. This will help avoid trip points.
