Air leak where exterior wall meets block foundation
So my family room is behind the garage and furthest away from the rest of the house. It's always cold. I was peaking under the siding this weekend and notice the house wrap doesn't come down to the block foundation. That wall is probably not sealed well against wind.
What’s the best move here to seal that up? There's no gap, nowhere to spray expanding foam in. I'm thinking of get some house wrap and trying to slip it under the siding with some adhesive to bring it down to the block foundation and then trim it to you can't see it.
