How often should you seal a deck?
Clean and reseal the deck every 2 years, or sooner if water stops beading on the boards. That is the interval the HomeAlmanac app schedules for this job, adjusted for the systems your home actually has.

Why it matters
Sealing protects wood from moisture and UV, preventing warping, cracking, and rot that shorten a deck's life.
How to do it
Clean the deck, let it dry fully, replace loose fasteners and rotten boards, then apply a quality stain or sealer on a dry day.
When to do it
Best done in summer, and the app schedules it for that season automatically.
HomeAlmanac schedules this one for you, works out the next due date each time you mark it done, and reminds you before it is late.
