Spring: getting ready after winter
- Cleaning: Start the season with a thorough clean to remove dirt, algae, and winter residue. Use a deck cleaner or a soft brush with mild soapy water. Avoid pressure washers — they can damage the wood fibers.
- Inspection: Check the deck for cracks, splinters, and loose screws. Replace damaged boards and tighten fasteners. Much of this can be prevented already during the build — see common deck building mistakes and how to avoid them.
- Treatment: If the deck went untreated through winter, it may be time for a fresh coat of oil or stain for extra protection — see how to finish and protect deck boards.
Summer: ongoing upkeep
- Light cleaning: Sweep the deck regularly to prevent buildup of leaves and dirt. This keeps algae from getting a foothold.
- Sun protection: Lumber can crack and fade in strong sun. Consider a UV-protective oil to preserve the color and strength of the boards.
- Spot cleaning: Treat stains quickly with mild soapy water to avoid permanent discoloration.
Fall: preparing for wet weather
- Deep cleaning: Repeat a thorough clean to remove leaves and other organic material that can breed mold or algae.
- Oiling: Apply oil or stain to strengthen the moisture protection. Make sure the wood is completely dry before treating it.
- Cover up: Use furniture covers or store outdoor furniture inside to extend its life.
Winter: protection against frost and snow
- Snow clearing: Remove snow with a soft broom to avoid scratches. Avoid salt and chemicals that can damage the wood.
- Checks: Inspect the deck after heavy snowfall and remove ice to prevent water damage.
- Airflow: Keep drainage paths open so water doesn’t collect and freeze under or on the deck.
