How often should you seal your deck?

Thumbtack Editors
Answered

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.
