Protect your encapsulated crawl space from mold and fungus. Keep your crawl space safe and clean all year.
Okay, Mr. and Mrs. Ballard, here is the mat cover here in the front of the house. This is your encapsulated crawl space. You can see I'll kind of walk you through everything that we've done.
First off we did the dry ice blasting for the floor joists that has removed all the fungus and we have treated that wood with the Board Cure Mold & Fungicide treatment, which will help prevent future growth. You can see the sub-floor is nice and clean. So that was the fungal remediation part of it. Then we installed the Closed Crawlspace System which is, we put a vapor barrier on all the exterior walls and piers. All your piers are done this way. Then we attached the Dow Thermomax insulation board over the top of the vapor barrier, which is what this silver stuff is right here. That's your insulation.
We don't have to insulate the sub-floor, but we do have to insulate up here, so we have to use the regular insulation all around the exterior of the foundation. You can kind of see how it is up on the exterior on your sill plate. So you've got a really good insulated crawlspace. It's going to allow it to breathe now because we've sealed it all off, we've got rid of the fungus, and your crawlspace is actually going to be conditioned. It's actually going to be about the same temperature and relative humidity as inside of the home.
So this air down here will actually get into the house which will make your air conditioning or heating system not run as much because, instead of hot, humid air, or cold air in the winter time getting into the house because your house has a natural upward air movement, you will have conditioned air getting into the house so it won't have to work quite as hard. We use this clear vapor barrier because masonry walls do allow some moisture to come through it. You can kind of see a couple of areas down here where it kind of looks a little hazy. That's a sign that moisture has been coming through that wall, so it was definitely a good idea to go ahead and do it this way. You can see here how we've taped all the seams together so it's all airtight, attached to the floor liner, which is what this white thing is, covering the ground.
It's basically like a pool liner. It's all airtight and waterproof to help keep all the moisture out of here. I'm going to go back up towards the front of the house a little bit, kind of get a little bit better view of everything. It's a little bit dark and I don't have a whole lot of light in here. We use this clear liner too, so this way we can still do a good termite inspection down here, and we can see termites coming up this wall before they get up to the top part, so we can take care of them if they ever do come back, and treat for them, so you don't have any wood problems. We've installed what's called supplied air inducers to the HVAC system. I'll kind of crawl back here.
You have two of them in your crawlspace, which are blowing conditioned air out of the trunk line, you main trunk line. That's what it looks like right there. There's one on this side of the trunk line and one on the backside of the trunk line. So you've got air blowing towards the front of the house and air blowing towards the back of the house. You can see this monitor, that's your thermo hygrometer, that's your remote sensor in the crawlspace. That's how you're judging the temperature and relative humidity. And that's about it. I hope you guys enjoy this.
Everything came out real good. We got a couple little things we need to come back and finish up, that the guys missed. Nothing big, just some cleanliness things. I want the floor liner cleaned a little bit better that what it is, but that's about it in a nutshell. Thank you guys for your business.
