How Often Should You Stain or Seal a Deck in Mobile?

How often a Mobile deck needs stain or sealer depends on its wood, age, condition and how much sun and moisture it gets.

Brush applying stain to deck boards

There is no single schedule. How often you stain or seal a deck in Mobile depends on the wood, its age and condition, and how much sun and moisture it gets. Watch for fading, graying and water soaking in instead of beading.

Signs your deck is ready for a new coat

Color has faded or turned gray

Water soaks into the boards instead of beading on top

The surface feels rough or looks dry

Coating is wearing off in high-traffic paths

Why sun and humidity matter

Decks in full Alabama sun dry out and fade faster than shaded decks. Decks under live oaks may stay damp longer. Both conditions affect how a finish holds up.

Choosing a stain or sealer

The right product depends on your deck's wood, its age and condition, and its exposure to sun and moisture on the Gulf Coast. We look at the deck and recommend the best option for it.
