Hi, guys, this is an issue today that we’re dealing with that is very common in mobile homes, and sometimes in house. That is the plastic underpinning, which is underneath the house that holds insulation, lets the heat radiate down to the insulation, keeps those water pipes from freezing is easy because of radiant heat.

But anyway that plastic is gone to now all that insulation is not held up against there, so somebody might have cut it to work on a plumbing issue or electrical issue. Any number of reasons animals got in there. It fell down. What I use is Lowe’s house wrap.

And it’s sort of like a fiberglass and wrap it up like so. And then make sure that there’s nothing underneath you like electrical or plumbing that you would screw into. But this way you can tighten it up and screw it down and. first, though, we’ve got to go under there and try to measure of how wide of an area we need and then we’ll go beyond and wrap it up.

So we open up the scrutiny and right away you can see where something has been getting in here. We’re going to try to that we’ll take a piece of one by and fasten it right there. If you look further up in there have been there, you can see the insulation is down right there.

And we’re going to have to crawl up in there and figure out how long of a piece we need of that. That tie wrap, that House wrap from Lowe’s. And we may have to do more than one section of it, and then we’ll screw it up and I’ll take you along with me.

This is a situation where a cameraman’s and danger just like me. But anyway, it’s not World War two midway. Now in this area. I can tell by looking at it that the a-coil or something similar to that is what caused the issue and water collapsed it.

So we’re going to I’ve measured and about eight foot that way will give me room past it. And now it’s eight foot wide from frame to frame. I’ll double check it. Yeah.

Alright, it’s a little bit more than that remember that we’re going to leave extra and won’t be able to run wood strips over this area, but we will be able to tuck it over this and you got to be careful when you fasten it to anything up in here because there’s water lines or electrical lines on, be sure when you put screws to the one by and up in through everything that you don’t fasten into a waterline or electrical line.

Now, I know I said that, but it is a little bit of a challenge to feel and pushing through this to find make sure there’s nothing on that floor joist that you’re fastening into, which would be over that way. In this case, we have uh, air conditioning duct work to worry about here.

If I wanted to, I could probably take this and fasten it with a one by, right there. But what I want to do is we let all this still be here, and then the heat will radiate down from the floor and keep the water lines from freezing.

That’s why they designed it that way. So we’re going to go outside and you’ll see me go out there and make the length eight foot by, ten foot by ten foot. No, I think that that house wrap is nine foot, so it’ll be nine foot by ten foot.

That allows me to wrap it up with the one by fasten it. That way, it won’t pull loose unless the screws pull loose and go to the other side. Wrap it up, pull it up until I get it tight and pull it up.

And then all this will be held up. So we’ll go outside and do that. Hey guys, one of my favorite tools that I lose a lot of them even though, because of crawling up under houses and up in attics such as a folding razor knife that allows you to change the blades.

In this case, you just pull that button right there back and you pull it out it gives you a slot there for your finger and then you pull your blade out and flip it over. It’s kind of cantankerous. Back over. Pull back and then you replace your blade. That way you don’t have to sharpen it, and you can tuck this in your pocket.

So that’s one of my more fun, very handy tools. And I’ll usually have one on me. Hi guys, as a repairman, I use a lot of knives and blades, or I use a particular type of blades. This is a folding razor knife, the push button right here, folds up, to open it up and locks in automatically.

But there’s a button right here and this one to pull back, pull down and then you pull that blade. You flip it over. And then you push back up. And it clicked in place, now we got a new changed blade and away we go again.

This is a very, very common use blade. You can get them at Lowe’s and other hardware stores and wish you well with it. But is one of my little repairmen tips. We measured. This is a nine foot house, wrap area that’s exactly about what we can use if it isn’t, it’s a limitation, we have.

And then I’ve measured from the end. It’s about ten foot right there, and then I put a one by underneath this, so I don’t dull my knife trying to cut it makes for better cut, and everything, so at the one by at that ten foot area and I just take. Imagine this is concrete underneath this, and it can dull pretty quick. I’ve only got eight foot long one strips, but you can get at Lowe’s, for like a dollar and a quarter apiece.

So now we’ve got the length cut we’ll do the tedious part, which is take this in, or underneath which you can roll it up or you just bunch it up and then stretch it out. And then we’re going to put the one bys, which we’ll throw those under from both sides and we’ll get screw gun and screws ready and then we’ll fasten it all up.
