Part 1: Crawlspace Depot DIY Installation

[@jimbojimjim3590]

Everything you have said in this video is so true I wish that home owners can see this video an let us help fix the problem in their crawl space

[@ben8606]

This is a great company. Thanks to these videos and the materials they sell I successfully encapsulated 2 houses. Thanks Crawlspace depot!

[@DIRT_CLOD_BOB]

These are the most helpful videos on the net for crawlspace encapsulation. Excellent complete explanations.of the DIY methods.

[@w.c.6678]

Good speaker for the company. Good information. Very professional video.

Air moving through the walls from crawl to attic that you mentioned is referred to as interstitial leakage. Openings around chimney and plumbing vent pipes are large cause. Clothes driers, running bathroom vents too long, and range hoods that vent to the outside, especially the new high capacity ones remove a tremendous amount of air which has to be replaced. Some range hoods move 1.5 to 2.5 tons of cooling per hour. That make up air has to come from somewhere, such as backdrafting the chimney, water heater, etc. Since learning about indoor air quality and thinking of the house as a system of interactive components, you are the first person to create a post that actually understands the true issues and dynamics of air movement through a building. No one lives in a sealed glass bottle. If air goes out somewhere, then air comes in somewhere. You are showing the difference between ventilation (the controlled movement of air) and infiltration (the uncontrolled movement of air.). Congratulations on your extensive knowledge and thank you for sharing it.

Such a roomie “crawl space”! Thank you for the video just poking because my grandfathers house has barely twenty inches

[@jasonhamby1185]

Great video! This is very true. INDOOR AIR QUALITY is most important.

[@elchebito]

This video was very helpful. Thank you sir, you're a real pro.

[@JasonGlisson]

This is such an excellent video. Thanks for providing the tutorial. Planning to do this on an older house that we're purchasing.

[@mrsfishguts]

THESE VIDEOS ARE FABULOUS! THANK YOU SO MUCH TO PROVIDING THIS INFORMATION.

[@Them353]

That's the largest crawl space I've ever seen...wow.

[@Wesslic]

Thanks so much for taking the time to make these videos.

[@leosrule5691]

Good video BUT that's NOT a crawlspace. Mine is 3ft access under house and a tiny hole in the floor of main house to get into it. Much harder to deal with!!!

[@williamdecamp7343]

It absolutely is a crawl space, there are no code restrictions to crawl space height and often times the land determines the height of the crawl space if it is sloping and they opted not to have a basement.

[@jeremybuchanan289]

All of these companies show videos of new houses with 4 foot "crawl spaces." Let's see how well they do in houses with less than 3 feet of clearance and pipes/wires/ducts running everywhere.

[@watchthe1369]

Seal the crawlspace like a lived in basement and use it as your air return for the HVAC? Keeps it dry, keeps air circulating becomes storage space and you get a look once in a while to see how it is doing?

[@CrawlspaceDepot]

There is generally no air return vent installed in the crawl. If you install an air inducer it will push 50 cubic feet per minute (CFM) of conditioned air into the crawlspace when the HVAC is running. And yes the crawlspace should be checked to make sure everything is functioning properly.

[@laurelshoger-hall1150]

I have rock walls, not concrete. Would you still recommend installing the foam board? I'm worried it will shift the rock or not attach well.

[@CrawlspaceDepot]

Laurel, It will really depend on whether the rock wall is flat enough to attach the foam board. If the foam board cannot lay flat on the wall it will be difficult to attach and big gaps under the board can reduce the thermal benefit. If the wall is too uneven you can run the poly up on the walls and use standard insulation under the floor joist. Thanks for asking!

[@sissymurphy9620]

If your floors are insulated can you still insulate the crawl space walls and what about insulating the crawl space floor .What about spray foaming the walls of the crawl space

[@CrawlspaceDepot]

Great question! If your floors are insulated you can still seal your vents and insulate the walls. Make sure your insulation is still in good shape as wet insulation is ineffective. We recommend Bora Foam because it is designed to deter termites from tunneling through the foam and the 3 mil poly on both sides of the board acts as the vapor barrier on the wall.

[@peytonthomas9378]

CrawlspaceDepot In your opinion, in a sealed crawl space, is having an exposed floor system preferable to insulating the floor system with fiberglass bats?

[@CrawlspaceDepot]

Peyton Thomas Advanced Energy's research showed insulating the crawl space walls was more efficient than a non-closed crawlspace with an insulated floor. They did not compare floor vs. wall insulation. If the floor insulation is in good condition we recommend leaving it in place and insulating the walls. If the insulation is hanging down and has been wet we recommend removing.

Great video....thanks

[@julesagogo]

Really great video - thank you!

[@marshallgoldberg8376]

The checklist is no longer on your website.

[@CrawlspaceDepot]

This is the checklist that we currently have online: www.crawlspacedepot.com/inspection-product-checklist/

[@chrischambless]

I’m in SoCal (low humidity) and my 80 y/o 2 story home has no air conditioning. With what you said in the beginning about vented crawl spaces predating A/C, how beneficial would a closed crawlspace be?

[@CrawlspaceDepot]

Hi Chris, Thanks so much for reaching out! We would say you are fine as you are if you have no a/c, low humidity and are experiencing no issues related to humidity. If you decide to add air conditioning and decide to encapsulate feel free to reach out and we would be happy to help!

Love This Vid U A LifeSaver Man Thanks About to Do My House

[@gmerrill1986]

Very good advice

[@robertclark785]

Is there a concern with existing mold when covering the foundation walls with the insulation board you recommended in the video. In other words can mold spores get trapped behind the newly added insulation and continue to grow causing a problem down the road, or is this not a concern? I have a crawl space here in Florida that I believe is causing an issue with moldly smelling condition in the house. I really like this approach especially since I don't have insulation between the floor joists. This would better insulate and control moisture at the same time. However, I am concerned about any existing mold that may be present before starting this project.

[@CrawlspaceDepot]

That is a great question Robert, thanks for posting it. Most installers will apply a product called Bora-Care with Mold-Care to the areas to be covered. This product kills mold and helps prevent future mold growth. Another point is that if everything is properly sealed you create an anaerobic environment below the poly or behind the foam board and as the oxygen is deleted mold stops cant' survive because it needs oxygen to grow.

[@apexheritage]

I was going to insulate out the floor. This seems cheaper and correct as an alternative.

[@Allenb1977]

Thank you for the video

[@21gonza21]

Wow can we even call that a crawl space when no crawling is necessary? I can’t even crawl on my “crawl space”

[@Jane20121985]

good presentation

[@MCGEE1115]

That's not a crawlspace, that' a short basement! It's called a crawlspace because it's only big enough to crawl in! Mine is less than 18" in places and maybe 3' at it's tallest side. My yard slants downhill and so does the crawlspace. If mine was that tall I would dig it out and have me a basement.

[@Cris-ss8tb]

Crawk space? That's a basement 😳
