You might think a drafty crawl space is no big deal, but an unsealed crawl space (especially in the winter months) can have a major impact on your upper floors. As heated air rises through a home, cold air is drawn into the poorly sealed crawl space through gaps and holes. If vent covers and crawl space doors are missing or damaged, or you have inferior fiberglass insulation in the space, you are at an even bigger disadvantage. Drafts and air leaks below your home will ultimately make for cold floors and drafty rooms above. Additionally, a crawl space left unsealed is an open invitation for unwanted moisture, mold, and nasty bugs and critters.
