I had no idea how bad the crawl space was, because I hardly ever go down there. When I inspected it, I was really surprised and disgusted at what was right under our feet. My wife has allergies that act up all the time, and it's no wonder why. After the guys were done installing the CleanSpace System by Best Home & Property Services, I was amazed by the difference. It's really clean and bright. It seems like the whole house dried out. It's really awesome.
