34 years of mold & air quality experience
Certified mold inspection, same-day air testing and professional remediation, led by Larry Harris and trusted from family homes to the courtroom.
Decades of experience, backed by real credentials
Larry Harris is a certified mold inspector with 34 years of experience. In 1998 he became a charter member of the National Institute for Indoor Air Quality. He has been an active member of NORMI, the National Organization of Remediators and Mold Inspectors, since 2004, and holds certifications in mold inspection, air sampling, thermal imaging, formaldehyde screening and remediation.
Every job starts the same way: a careful visual inspection and relative humidity readings, because mold can start to grow once indoor humidity reaches 60%. When air testing is needed, a morning test means a lab report the same afternoon, so you are never left waiting days for answers.
From the Columbia, SC Midlands, Classic Systems serves South Carolina, North Carolina and Georgia, working in homes, commercial buildings, school classrooms, hospitals and medical facilities, and university dorm rooms.
