• Rot
?? Type of Sealer Used
• Basic clear sealers: 1–2 years
• Semi-transparent stain/seal combos: 2–3 years
• High-end oil-based products: often last longer
?
?? Easy Water Test
Sprinkle water on the deck:
• ? If water beads up ? Still protected
• ? If water soaks in quickly ? Time to reseal
?
?? Pro Recommendation
For pressure-treated wood:
• Wait 2–3 months after new installation before first sealing (let it dry properly).
• Clean before sealing.
• Never seal damp wood.

Bottom Line
In East Texas conditions, most pressure-treated decks should be cleaned and resealed about every 2 years to maintain strength and appearance.
| | Clean Cut Decks | 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
