Introduction

This guide provides a simple method to replace broken deck boards on an outdoor wooden patio. Wooden boards can become damaged by impact or excessive use, water damage, age, rotting, fungus, or termites. By replacing the damaged boards, you can restore the structural integrity and appearance of your old deck, rather than replacing the entire thing.

By following all the processes, users will have fun by finishing their own DIY project that will bring more self-satisfaction.

    • Measure and estimate the new boards you need to purchase.

    • We recommend using treated 5/4-inch x 6-inch lumber that you could easily get from any home improvement stores.

    • Remove the broken boards.

    • If your boards were originally put down with screws, then remove the old screws with a drill.

    • If your boards were originally affixed with nails, pry the nails up before removing the boards.

    • It's generally recommended to take a more gentle approach, otherwise you may destroy the joists.

    • Check and sweep the joists.

    • In most cases, deck framing typically takes a lot longer to deteriorate because it is protected from the sun, wind, and rain by the boards above it. So joists should be in good shape.

    • Use a hand saw to cut along the marked cutting line for each new board.

    • A circular saw is recommended to expedite the process if there are many broken deck boards to be replaced.

    • Pre-drill the holes at the marked spots using a 1/8th inch drill bit.

    • Drive screws into the pre-drilled holes.

    • Use a wet scrubbing sponge to clean up the lines.

    • You may choose nails but screws are always preferable to nails when fastening deck boards.
