The Crawl Space Fan Trap That's Destroying Your Home

  I just want to say thank you for all the education you have provided me.  We went from owning a stick built house with a regular basement to a mobile home out in the country.  When I built the skirting for the crawl space i added 6 mil poly to the ground as per the recommendation of the building inspector.  I also fully insulated the skirting walls to R14 and vapour barriered them from the inside, to keep the house from getting too cold underneath in our brutal winters.  Looks like I got those things right!  Here's where I went wrong.  I opened up all my vents this summer and turned on the heavy duty fan (our first summer here), its been very humid and i wake up the last couple days and humidity levels have soared to 99% under the home. I have a wireless temp and humidity sensor under the house so I can monitor readings easily.  Off to YouTube I go to figure out what I can do!  I watched your videos for hours last night.  This morning I put a dehumidifier underneath the home, closed up the vents (insulated as well) and started dehumidifying and to my pleasant surprise I've dropped 10% in just a half hour and still dropping. Thank you so much for posting all these videos online, you literally protect peoples homes and personal health by providing this service.  cheers!

  The music they use really takes me back to the old TV shows and cartoons I grew up watching . Can't put my finger on the exact shows but man is that a nostalgic sound track hahaa

  Dang Michael, Great video. Wished you were in the Pacific Northwest. Working on getting my garage <br>dried out, I was gonna add an exhaust fan, but now I see it&apos;s all about using a dehumidifier.

  Good work guys. &nbsp;It is amazing how many builders don’t take crawl space air quality seriously. &nbsp;Out of sight, out of mind until the homeowner or inspector finds mold. &nbsp;Glad to see you guys sharing your expertise on how to manage these spaces.

  That one reason why I just hired crawl space ninja to do my crawl space after I received four different companies and ninja went far to explain all details.
