I felt like these guys were life savers. I didn't know much about mold, but when they found it and determined the source they were able to help me out by giving me great advice. While they were down in my crawlspace they had found some wet asbestos piping that was in pretty rough shape. I would definitely recommend these guys and they even showed up on time...a few minutes early even! You don't find that too much, especially after I had just waited 3 hours on the cable guy to arrive!
