What the IICRC Is

The Institute of Inspection, Cleaning, and Restoration Certification is an independent nonprofit that develops and maintains industry standards for the cleaning and restoration industries. The IICRC S500 Standard for Water Damage Restoration and S520 Standard for Mold Remediation define the technical requirements for professional restoration work. IICRC certification means a technician has passed testing demonstrating knowledge of these standards.

Key IICRC Certifications for Water Damage

WRT (Water Restoration Technician): the foundational certification for water damage restoration. Covers water damage categories, moisture physics, and drying principles. ASD (Applied Structural Drying): advanced certification focusing on drying systems, psychrometrics, and monitoring documentation. AMRT (Applied Microbial Remediation Technician): certification for mold and microbial remediation following S520 standards. FSRT (Fire and Smoke Restoration Technician): relevant for fire damage jobs. For water damage jobs, verify WRT and ASD at minimum.

How to Verify IICRC Certification

The IICRC maintains a public online registry at iicrc.org where you can search for certified technicians and firms by name. Ask the contractor for the individual certification cards of the technicians who will be on your job -- not just a company-level claim. Company IICRC firm registration does not guarantee every technician is certified.

Certification vs. Licensing

IICRC certification is a voluntary industry credential. State contractor licensing is a legal requirement in most states. Both matter. A licensed contractor is authorized to perform work in your state. An IICRC-certified technician has demonstrated knowledge of professional restoration standards. Look for both.

Other Credentials to Consider

OSHA 10 or 30-hour training indicates safety training for job site workers. RIA (Restoration Industry Association) certification is another industry credential. Some states have state-specific mold remediation licensing requirements -- check your state's requirements.

Frequently Asked Questions

Do I need to hire an IICRC-certified company for water damage?

IICRC certification is not legally required in most states, but it is the best indicator that a company's technicians have been trained in the technical standards for proper restoration. For insurance claims, many adjusters look favorably on IICRC-certified contractors. For your own protection, prioritize certified technicians.

What does it mean if a company says they are an IICRC Firm?

IICRC Firm status means the company has registered with the IICRC and committed to maintaining certified technicians and following IICRC standards. It is a step above no affiliation but does not mean every employee is certified. Ask for individual technician certifications for the crew doing your work.

Is IICRC the same as being licensed?

No. IICRC is an industry certification organization. State contractor licensing is issued by state government. Both are separate requirements. A company can be IICRC-certified without being licensed and vice versa. Verify both.
