Charlie: … Thym in Spring. Anyway, he says we had to have our wall open due to Harvey, and there’s a plastic vapor barrier on each side of the walls. If you open it a little, you can look down and see that there’s old mold growth between the exterior walls and, what he thinks is, a vapor barrier. The mold’s dead now, but it must’ve been there at some time. He’s wondering what does he do about this, Tom? Should he clean it out by hand? Should he spray some KILZ in there is what he’s asking.
Tom: KILZ isn’t going to do anything so, no, don’t spray KILZ. I don’t know why people are so into that.
Charlie: Good branding.
Tom: Yeah, absolutely. It’s like Thompson’s, very good branding, or Whataburger. Oh, wait, that’s for later today.
Charlie: That’s good stuff.
Tom: If it’s dead, you say the mold is dead and that’s the way the house was built, put it back together. I think that’s all you have to do.
Charlie: He’s talking about that black, what looks like plastic at the bottom.
Tom: Yeah, that’s down by the brick just to keep the water from going in the weep holes, and there are, I don’t know, tens of thousands, hundreds of thousands of homes throughout the country that have that little 18-24 inch plastic at the bottom. If you sprayed it with a little con sand or you sprayed it with whatever your antibacterial product was you sprayed it with, let it go and put the thing back together. It’s there for a reason.
Charlie: The reason is it’s a detail that stops the water from coming in or something?
Tom: Yeah, when the water drips down the bottom of the brick, it’s going to go out the weep holes and not crawl back under the wall.
Charlie: Okay, super, so just leave it is the bottom line.
Tom: Leave it alone. If it’s only that little piece, just leave it.
