Our first step was installing flashing. This wasn't done originally and is the reason for the dry rot against the house. The hardware store only had 3 inch L flashing. We needed 2 inch, so we made do. My Charles trimmed it down with our metal shears.
We also had to strengthen the structure a bit, as we discovered part of a footer missing and also that some of the boards are getting a bit spongy. Next spring, we'll be replacing the entire deck, and we'll be using composite thank you very much, but for now, there are a few more steps to get the deck back together and strong before the snows come (this weekend, eek!).
