This Selbyville Delaware resident noticed the high moisture content in the crawlspace. Since the crawlspace contained no duct work or mechanical equipment the homeowner decided to remove the fiberglass insulation from the joist and spray a disinfectant to kill the microbial growth. A closed cell foam will be used to place of ineffective fiberglass batt insulation. The closed cell foam will serve as a vapor barrier protecting the crawlspace wood from rot.
