We live in a sad time when a pressure treated deck doesn't even last 10 years. I built mine 15 years ago and after about 10 years, the deck boards were rotting badly. Pulled some off the the treated joists are also rotting in several places even though they are ground contact rated and are 2-3 feet above the ground level.

Now I need to decide if I pull the desk out completely and just build small platforms and a few steps for the 3 french doors and plant grass or if I do pavers or stone.
