IICRC Certifications Explained
Which restoration certifications matter, which to get first, and how they’re different from a state license.
The IICRC (Institute of Inspection, Cleaning and Restoration Certification) is the best-known certifying body in restoration. Its credentials aren’t legally required in most states, but adjusters, insurance companies and property managers look for them. I’m IICRC certified, and here’s how I’d think about them.
The ones that matter most for water and mold
| Certification | What it covers | When to get it |
|---|---|---|
| WRT (Water Restoration Technician) | Water damage basics: categories, drying principles, equipment, safety | First. The foundation for everything else. |
| ASD (Applied Structural Drying) | Hands-on drying of structures: equipment setup, monitoring and drying science | After WRT, once you’re running jobs |
| AMRT (Applied Microbial Remediation Technician) | Mold remediation: containment, removal and safety | When you’re ready to step into mold |
| FSRT (Fire and Smoke Restoration Technician) | Fire and smoke damage cleanup | If you add fire jobs |
| OCT (Odor Control Technician) | Finding and removing odors | If you add odor work |
Course names, prerequisites and renewal requirements change. Check the IICRC website for current details.
Certification vs. state license
A certification shows you were trained to an industry standard. A license is issued by a state and is a legal requirement where it applies. In a few states, like Florida, Texas and New York, mold work needs a state license on top of training. See the mold licensing requirements for every state.
What certifications won’t teach you
Certifications teach standards. They don’t teach you how to win the job on the first call, write an estimate that gets approved, or get paid on time. That’s the business side, and it’s what the 6-Figure Launchpad covers. Start with the free From Leak to Paycheck playbook.
