How to Replace Tongue and Groove Boards in Hardwood Flooring

The interlocking design of tongue-and-groove boards means that it is necessary to cut through the board joints to release them from their position. A circular saw is ideal for this purpose.

Prepare to Cut

Use a nail cutting blade to cut through any concealed nails. Set the circular saw to the exact depth of the damaged board.

Cut Around the Damaged Board

Run the saw down the entire length of the board on either side of the damaged area where possible.

Pry Out the Damaged Board

Use a pry bar to remove the damaged board. Rest the bar on a wood offcut to prevent the bar from damaging adjacent boards.

Prepare the New Board

Remove the tongue from the new board, using a sharp chisel. If the boards are very thick, you may need to use a saw.

Place and Finish the New Board

Reposition the new board in place. Since blind nailing is not possible, use finish nails and fill the holes.
