This project I didn’t show you when we pulled all the furniture out of the trash. It’s pretty, pretty bad. We hauled all that off also, and so far we’ve pulled out 4400 lbs of trash to the trash. The real issue is the floor dropping in right here. I don’t know for sure what the issue is. The floor joists are right there.

I’m thinking that is because of the air conditioner filter problem being closed and the rain water at the front so that the back shows water stains down through here, right over there, the plywood, the exterior plywood on the outside was swelled up and rotted. That might have caused the ends to get rotted, but it certainly would have caused all this. So I’m assuming water running from this air conditioner across to the carpet, which was here, and the pad soaked through to the particle board. And we’re going to have to cut all this up and find out just how bad it is. So you guys will be joining us as we go into a unique situation.

We cut through the floor. We’re cutting a hole with a saw. Sort of like you do in mobile homes cut it in between the joists. This is the floor joists. I’m really not that strong. Sometimes I smell strong, but I’m not that strong. So it’s been wet for a long, long time. And our job is to make it better. It’s went through plywood underneath and then particleboard and then the floor joists, so. It had plastic too, by the way. Some how it still got through all of that. So here we go.

Couple hours later. When I say couple, I mean two. We’ve got all this out. And that one, although it looks… it’s pretty good and we’re going to put new floor joists in. I’m going to try to encourage them to put plastic down so that we won’t get moisture up on to the floor joists. And I don’t know if they will want to put insulation floor, but that’d be a good idea. And then we’ll put half inch OSB down and then a tongue and groove flooring.

Some of this area we’ll have to cut the particle board and we’ll leave the plywood. The half inch plywood, we’ll cut this out because it’s just too swelled up. Like behind on this area here. It’s all swelled up because of moisture.

And we’ll cut that out and put new in. But this is what you can do in a couple of hours, two and a half hours. Plus talk to the guy that owns this place. Who is thoroughly depressed and disappointed. What we’re going to do now is continue to clean up and pick up and we’ll take you through, as we put all back together.

What you do, is put in another two by ten here to help feel more secure about the support of this wall. Because that was rotted, also now that’s something I want to take out and mess with the siding. And I talk to the owner about it. This area here, we know to replace it from the outside so I went ahead and covered this area. So again, I feel more solid, but we’re going to put another one out here. Even so, we have something to screw the plywood to and give it more support on that edge. And that’s what we’re up to now.

We’re going to put in floor joists and we have those ready to roll and we’ll have to fasten them. Mark on that wall.

Okay. So far, all what an hour we put in all of the floor joists, lay out and the guys are struggling. They’ve got all the plastic on the ground, which is something I’m wanting to do to make things better.

We’re using pressure treated. You don’t have to. But it doesn’t cost that much more to going to put pressure treated down. And it’s the second time in in very very recent that I’ve seen a plastic in the flooring catch water and then rot everything for joists and everything. So you might think about what kind of consequences is probably the fourth or fifth time I’ve seen it over my 26 year period in this area.

Um, so I probably wouldn’t put plastic in between the layers. I understand there’s probably a reason, but if water gets consistently on there, it spreads over a larger area than if it wasn’t there to stay in one area, maybe for three or four feet. And this wouldn’t be as big a project. But now we’ve screwed everything, and now we’re getting ready to put down plywood and some floor stiffeners.

And we’ll bring it in when we get this half inch plywood. This matches what was already there. Uh, and then we’ll go the other way with the thicker plywood. Fasteners, 3” screws and uh we’re going to do more of the same. But we’re going to use a different type of plywood on top of this. Probably run it across the right… the floor joists now that I think about it. So we’ll be doing it.

3 hours in. We’ve got all the plywood down. Screwed off. Replaced the areas of particle board that swelled up, and we’ve cut out the outside edges where we’re having to pry it up to put in the better plywood.

And have to do the same over here. It’s not all easy work, but they didn’t hire us because we’re Wal-mart greeters. We’ve got to do the work. All the swelled up areas with new plywood screwed everything down. And we’re going to put floor leveler on it.

In our discovery in the kitchen and dining area was five year old Rockstar, 10 year old Rockstar. I don’t think it’s like wine, where aged is better. So we were trying to see who would be willing to take this. And this… Taste test for longevity of Rockstar and rock star recovery.

You might need recovery if you drink 10 year old recovery Rockstar. This is uh, 10 calories, but it’s non-carbonated lemonade taste. And this is Pina Coloda five year Pina Coloda. It’s probably going to be something close to wine. But anyway, there you go. Lemon flavored Rockstar, he’s opening it and it got carbonation still.

“Here, you smell it. You said you would drink it.”

Smell it, smell test.

“It is definitely no good. It smells like rancid lemon.”

So, to go by faical expressions I would not drink it.

“You smell it.”

I don’t know.

“Go ahead and take a taste.”

No, I’m not getting paid enough.

“I told you 10 bucks if you drink it.”

“You won’t have to pay me back. My supplies.”

“Go once.”

I’m not paying for it.

“Oh, it looks like you almost drank it.”
