Hey, michael Church, Crawl Space Ninja. Today we are launching our brand new Crawl Space Misconception Series Is loose-laid vapor barrier all you need to control humidity in your crawl space. So when we're going against competitors out in the market like HVAC companies that are doing a little bit of crawl space work, pest control companies and things like that, one of the misconceptions out there, because of the building practices that we have in this country, is that a loose laid vapor barrier a black six mil, for example, or a clear six mil vapor barrier just thrown on the crawl space floor, is good enough to control humidity. Now the interesting thing about that is if you seal the vents of the crawl space, you just took that vapor barrier out of code, because code says that once you seal the vents or you create a crawl space that is sealed and dehumidified, the vapor barrier or the plastic now needs to go up the walls and be mechanically attached. So the only time you should use a loose-laid vapor barrier if you're looking to install one, would be if your vents are open and or you have ventilation fans with an open crawl space Okay. So just keep that in mind.

If you're looking to encapsulate, then the loose-laid vapor barrier becomes out of code. But let's think about this for a moment. We just throw plastic down, we don't seal it, we don't seam it with tape, we don't do anything. And then your HVAC contractor or your pest control company or whoever goes in and out and, as that happens, that vapor barrier starts to separate and expose ground. Because most contractors do not overlap the vapor barrier, they'll just take this piece and butt it up against that piece. I put my knee over here and then that piece shifts that direction. So now the ground is exposed, all right.

The other thing is is that there's more places inside the crawl space for humidity to enter other than the ground, and if it's not sealed and not properly attached to the wall, then it's not really doing a good job at even preventing moisture from the earth from getting up into the crawl space. So one of the misconceptions out there is that a loose-laid vapor barrier is good enough to control humidity. If you're having your home built and all they're doing is laying down a loose-laid vapor barrier, they are only doing what code requires. If you've been in your home for a long time and you look in and you see a black six mil plastic that's not taped and all that sort of thing. I would encourage you, especially if you live in a humid environment, to look into a full encapsulation with dehumidification in order to control humidity. I'm Michael Church, crawl, space and Energy. We hope you make it a happy and blessed day. We'll see you later.
