If a crawl space has not been cleaned in a long time, it can be contaminated and causing bad odors. The crew begun by removing all the old decomposed insulation. Then they sanitized to kill all the bacteria and get rid of any odors. After, the crew installed wire mesh to cover up any entry points in the crawlspace to rodent proof. Finally the crew finished up by installing R-19 Batts insulation. With a nice and insulated crawlspace the home will now be more comfortable.
