 All right. Good morning, YouTube. So I am In the attic of the house that we were working on yesterday. So you can see spray foam behind my head here I'm wedged in one of the new all addicts. Actually, it's not so bad. This one's pretty big But I want to show you some leakage. So in testing this last night before I left I figured out that this was about 20% connected outdoors still so it's way better than the 45% It was before but it's still fairly leaky But the curse of air sealing is you really can't find the next leak until you seal the big ones So the three rules of air sealing are rule one seal the big leaks rule two seal the medium leaks rule three Seal the small leaks. So you have to just kind of work your way through it one to another to another to another So that's what we have done So we've knocked about a quarter of the leakage out of this house so far But but I know there's more and I know there's more upstairs. So I'm gonna turn the camera around and I'll show you one spot So I am in the knee wall here. So here's the new bath fan And you can see the roof is foamed. We left insulation in here mainly for sound and just a little bit of Insulation from this space here. It doesn't really matter that much But underneath here is what's the pain is the part to pay attention to so this is the knee wall so right on the other side of this is a bathroom and I showed in the video yesterday What happens underneath here? so Down under here You can see it just kind of disappears and you can't really see it But it falls off a cliff down to the basement. So we're gonna seal the basement up Which might seal these leaks up This is where you really have to kind of Begin to understand how houses work, but before I do that, let me just show See, so can you see that little guy right there flaring the breeze? This is leaky enough. I have the blower door on right now Sucking air out of the house. So it is pulling air in through any leaks and I also have My trusty or wizard stick wizard stick smoker here. So I'm gonna get it going You can't see how there we go So you can see Right there. It's kind of lollygagging out. But when I put it down here You can see it's it can't blow out of there fast enough. So I know there's a leak there So we are going to seal the basement first and then we will come up here and Get this sealed, but here's what's going on here So this disappears underneath there and it's somehow connected to an outside wall Through the first of the second floor because this is the third floor of this house So somehow it's connected through there. You don't really know how it doesn't really matter anyway We know that we have to seal that particular joint. So we're gonna come back later and deal with that one and I'm really curious to see what kind of number we can get out of this house because we're already down pretty close to the target We started at 8,000 Originally and we are down to a little under 6,000 now And targets 5,500 so I'm really excited to see what happens and I will report back later
