Second time I have used Clean Crawls to redo a crawl space. It was so clean and well insulated that my son wanted to move his room to the crawl space. They even made me a nice screen door to better protect the furnace access. Had them come back recently when I had a dead rat problem and they took care of it, got rid of the bodies (and the smell), cleaned everything out again, poured cement where the rats were burrowing in, and are now following up with bi-monthly checks. Wonderful service! They take care of all imaginable crawl space needs.
