We arranged for a lab to be «sanitized» by this company, a local office I gather in So Cal. The cost was very high, and two high school kids showed up with no supplies, and no knowledge about the job, or even how to protect themselves had we not already done the work. They went to WalMart and bought Simple Green cleanser and paper towels came back and wiped the lab and equipment down then provided a bogus looking certificate. From my experience this place is bogus and not worth considering. Can you give a negative 5 stars rating — that would be mine!
