Wood decks see a lot of wear and tear over the years.
Is the damage limited to just a few boards?
If so, there’s no question that patching is the best route.

Oftentimes, damage on the surface is indicative of damage beneath the surface.
This shouldn’t be cause for more concern, as most damaged joists can easily be patched as well.
Most decks are constructed using 5/4 boards, which are 1-1/4 inches thick.

Match the looks and smell with the boards you’re purchasing.
If you see damage on the top of the deck, look for damage beneath the deck.
Compromised joists will need to be structuralized as part of the repair.
If the joist is significantly damaged, you might need to sister the joist across its entire length.
Warning:If your joists are significantly damaged, consult a licensed contractor before moving forward with your repair.
To find the joist, simply look through the cracks between the boards.
Step 3: Cut Out Damaged Boards
Carefully cut the damaged boards from the deckusing a jigsaw.
Hold the jigsaw straight and refrain from cutting into the joist below.
Step 4: Remove Boards
Remove the damaged section.
Repeat on the other end of the removed section.
To prevent splitting, drill pilot holes using a drill bit slightly smaller than your fastener.
Tip:While the joist is exposed, seal any damaged or unsealed areas to protect from future rot.
Position the board with any obvious cupping facing upward, so the board sheds water rather than holding it.
If you see no obvious cupping, inspect the end grain and aim any obvious curvature upward.
For the best results, sand, stain, and seal your entire deck after installing the replacement boards.
Stain and seal your deck annually or biannually for the best protection.
Additionally, look for reasons that your deck was damaged in the first place.
Are there gutters draining on your deck or leaky spigots?
Resolve any issues to ensure your deck last for years to come.
