 You take care of them. But if you just have a deck on the back of the house, it's six, eight feet off the ground. After 15 years, you can have some serious issues as far as structure if you haven't taken care of it. So make sure that if you've got a few years into it and maybe somebody built this deck and painted it, you don't even know what's underneath it. But if it's built out of just regular dimensional lumber versus a pressure treated or a treated wood.
