Repairing a deck board seems like a straightforward and easy DIY job. There are several steps to proper and thorough decking board repair, however, that may make you think twice and decide to hire a pro to repair the deck for you.

First, remove all nails and screws from the damaged decking board. Inspect the joists and remove the rotten sections of the boards. Measure the exposed section and cut new boards to size. Apply sealant to the newly exposed boards and reinforce and secure the joist. Apply matching wood stain to the new board and nail and/or screw into the existing deck.

It’s not always easy to know if your wood deck is rotten, as rot can begin in areas not easily visible to the naked eye. There are some signs to look out for, though, and it’s important to inspect your deck every season to ensure it’s safe and there are no hazards that need to be addressed.

If your wood deck is older, it may begin to show signs of dry rot, even if it’s made of pressurized wood. Dry rot includes spongy and discolored wood that can flake off or disintegrate when it becomes wet. You can use a screwdriver to test areas of a wood deck for dry rot. When you see signs of dry rot, it’s important to address the problem and get it repaired as soon as possible, because the problem will only get worse and the deck may become dangerous to use.
