"He was friendly, very professional, and answered all my questions clearly about how mold happens in a home. His reasonable estimate and scope of work. What are the steps for mold remediation? Furthermore, I had delicate items around the work area. He was very successful in making sure that nothing was damaged. "Think floor demolition in a China shop" where none of the dishes gets broken. I highly recommend restoration Hunter if you have to deal with mold in the home."
