#  Institute of Inspection, Cleaning and Restoration Certification IICRC 

 The non-profit standards-setting body for the cleaning, inspection, and restoration industries. Publishes the technical standards that define what 'professional' means in carpet and water-damage work. 

## Detailed definition

The Institute of Inspection, Cleaning and Restoration Certification — universally referred to as IICRC — is the non-profit organization that publishes the technical standards governing professional carpet cleaning, water damage restoration, mold remediation, fire and smoke restoration, and several adjacent disciplines. It’s been the de facto standards body for the industry since the 1970s.

The standards that matter for commercial cleaning work are:

* **S100** — Standard for Professional Cleaning of Textile Floor Coverings. Defines methods, equipment specs, technician procedure, and pre-inspection protocol for carpet cleaning.
* **S500** — Standard for Professional Water Damage Restoration. The reference document for what classes of water loss require what drying approach, dehumidification calculations, etc.
* **S520** — Standard for Professional Mold Remediation. The reference for containment, PPE, and remediation procedure on mold jobs.

Individual technicians and firms can earn IICRC certification in specific disciplines. The most common technician certifications are Carpet Cleaning Technician (CCT), Upholstery and Fabric Cleaning Technician (UFT), Water Damage Restoration Technician (WRT), Applied Structural Drying (ASD), and Carpet Repair and Reinstallation Technician (CRRT).

**About CCSD’s IICRC status.** Joe held IICRC credentials earlier in his career. They are currently expired. We still work to the IICRC standards on every carpet and extraction job — the operating procedures, equipment specs, and inspection protocols are baked into the way we do the work — but we don’t claim current IICRC certification, and we won’t list it on quotes or marketing material until it’s renewed. If current certification is a contract requirement for your facility, tell us early so we can plan around it or partner accordingly.
