Check the deck wood for soft, spongy areas. Walk over the entire deck and stairs, feeling for soft spots by pressing with your shoe.
Run your hand over the railings looking for spongy areas. Get under the deck and tap different areas with a screwdriver. Examine the deck posts for soft spots.
Stick a screwdriver into any soft areas of the wood you find. If the screwdriver penetrates more than 1/2 inch deep, replace the wood piece. If the rot is less than 1/2 inch deep, apply a water sealant to the entire deck to stop wood rot from becoming worse.
Things You Will Need
- Remove standing pools of water from decks by sweeping away with a broom or blowing dry with a leaf blower.
