In our new construction house we chose to seal our crawl space. We did this for a number of reasons. We didn't want our crawlspace to have the same moisture and mold issues that a lot of traditionally vented crawlspaces have. We also wanted to keep the floor of the house a little warmer. One of the big reasons we chose a sealed or Conditioned crawl space is because there are Radon issues in our area. Radon is an odorless, colorless gas that can cause a lot of health issues. Sealing the crawlspace will keep Radon Gasses from entering our home.
