Something we run into a lot of these people not using galvanized nails, alkaline copper quaternary screws, or ACQ screws for attaching any type of pressure treated wood. A tip for you old-timers, the CCA and the ACQ are 100% different. The ACQ is more corrosive than the old stuff. So, some of these old-timers that are like, "I used nails and I had no problems." Well, it's not the same anymore. These issues can arise within years, months in some cases, I'm sure. So, if it's something you did before, maybe you need to think about what you're doing now.
