A deck on the Emerald Coast lives outdoors in one of the hardest residential climates in the country: salt in the air, sun overhead most of the year, and humidity that never really leaves. Here's the honest upkeep schedule for each material.
If your deck is wood
Twice a year, wash it. Not just for looks — salt film and mildew hold moisture against the wood. A cleaning in spring and fall, with a deck-appropriate cleaner, resets the surface.
Watch the water-drop test. Sprinkle water on the boards. If it beads, your sealer is working; if it soaks straight in, the wood is drinking every rain, and it's time to re-seal. On our coast that typically comes around more often than the label promises, especially on sun-facing decks.
Tighten and inspect annually. Humidity cycling works fasteners loose. Walk the deck each spring: popped screws, wobbly rails, and any rust bleed around fasteners — that last one is a flag worth reading about in our fastener post.
If your deck is composite
Easier, not effortless. Wash off salt, pollen, and mildew a couple of times a year with soap and water. Keep gaps between boards clear of sand and leaf litter so water drains. And give the same annual glance to the frame and connectors underneath — the composite surface outlives its steel if nobody looks.
Either way: look underneath once a year
Five minutes with a flashlight under the deck tells you more than an hour on top of it. Soft joists, rusting hangers, and post bases holding water are all cheaper to catch early.
