Like others have mentioned....keep your wood stained/painted. Keep holes filled in. If and when you redo your deck or remodel, go with alternatives like Trex and Hardie board if you can swing the added costs. It's been a point of contention between me and the wife. She has this fascination with "real wood". Loves it....until it's time to paint/stain/deal with carpenter bees/etc. I won out on my deck and it's Trex. I pressure wash each spring and it looks as good as the day it was installed. She got her cedar rails and pressure treated stairs. Every 2-3 years, it's time to repaint/stain. I don't do paint/stain. Those were the rules when these decisions were made. I don't say "I told you so", but man, I do think it and smile.
