Reply to comment by wowsuchtroll in Do I need to replace my deck joists? by RobotKevinSpacey

My parents deck went 25-30 years before they had to replace their pressure-treated joists.

Same, but this really depends a lot on how close to the ground the deck is. My parents had a multi-level deck and the ground-level portion rotted after about 20 years. The upper level portion will probably last 100; the joints still look new @ 25 years.

Yeah, I have a ground level deck and after ten years two joists have minor rot. Okay for now but will probably need to replace in the 2030s.
