How often should you seal your deck?
It depends on the climate, your deck’s age, its condition and the type of sealer you use. Some experts recommend adding a sealing product at least once a year, while others advise every three years. If your deck is frequently in hot, direct sunlight or harsh conditions like rain, high humidity or snow, you'll likely need to apply a seal at least once a year. Contact a deck sealing professional near you to find out if it’s time to re-seal your deck.
