Top Answer (61% of 39 votes): Every 2-4 years.
Answer: Every 2-4 years
Explanation: Pressure-treated wood should typically be sealed every 2 to 4 years depending on sun exposure, moisture levels, and foot traffic. Over time, the protective qualities of the initial treatment diminish, leaving the wood vulnerable to cracking, warping, and mildew. A good rule of thumb is to test annually by sprinkling water on the deck — if it no longer beads up, it’s time to reseal. Regular maintenance extends the life and appearance of your deck. | | Vassett Painting and Construction LLC | Answer: Every 2-4 years
