 Hi, this is Nate Adams with Energy Smart Home Performance, and I want to show you a problem that I found in a spray foam job, pretty typical, and you just have to check after the fact to find out. So this is a client house. This is an addition here, and you can see everything's gotten foamed. Even a wall that's in the middle here, this is open cell for sound absorption. But this wall right here is the wall in between the old house and this addition. And if you take a look at the top there, that is where it connects to the attic over the old house. So I didn't have much time to be here. I didn't catch this, which is kind of typical. If you only have a little bit of time, things like this are going to get missed. And this is a big miss. In doing blow door testing, this room was about half connected to the outdoors, so it's really a very problematic room. And this space right here is going to be most of it. I'll find out soon, but I know that's the biggest piece of the puzzle. So I'll get that foamed up and we'll get it taken care of. So if you have a little bit of time after the fact, you can catch things like this, and then this won't get missed and get drywall put up and then get some kind of crazy rot on this wall here and wonder what's going on. This will be all taken care of.
