The check takes about two minutes: search the company's legal name, confirm the credential (CR-65 — Household Cleaning and Water Damage Restoration, B-1 — General Residential Contractor (for structural work), B — General Commercial Contractor (for commercial buildings)), verify Active status with a future expiration, and scan for disciplinary actions. Arizona's CR-65 is the only U.S. state-level license specifically for water damage restoration — most states cover this under general contractor categories Never take a logo's word for a license the state will confirm for free.

If the Mold Followed a Leak
Stop the water at the fixture valve or the main, cut power to wet rooms at the breaker if you can reach the panel safely, move what you can out of the water, and photograph everything before it is touched. Water that has reached carpet pad, drywall or a subfloor is a same-day restoration call rather than a cleanup: mold can establish on wet materials within 24–48 hours, and every hour of delay moves materials from "dry it" to "replace it."
Before You Sign Anything
Ask for a written scope and the pricing basis, who is fixing the water source and when, and what the moisture readings are — a company that does not take readings is not drying. Sudden, accidental water damage (a burst pipe, a failed supply line, an appliance leak) is usually covered by homeowners insurance; long-term leaks, neglected maintenance and rising outside water usually are not. Document first, then call the restoration company, then the insurer.

Frequently Asked Questions
Does Arizona require a license for mold remediation?
YesArizona licenses mold work through the Arizona Registrar of Contractors (ROC). The credentials to look for: CR-65 — Household Cleaning and Water Damage Restoration, B-1 — General Residential Contractor (for structural work), B — General Commercial Contractor (for commercial buildings).
Arizona's CR-65 specialty license is the specific category for water damage restoration and household cleaning services — the only state in the U.S. with a dedicated water damage restoration license class. Contractors performing structural reconstruction after water damage also need a B-1 (residential) or B (commercial) general contractor license from the ROC.
How do I verify a company's mold license in Arizona?
Use the official ROC License Lookup — it's public and takes about two minutes: search the company's legal name, confirm the license type matches the work (CR-65 — Household Cleaning and Water Damage Restoration), check the status is Active with a future expiration, and scan the same record for disciplinary actions.
When verifying an Arizona ROC license, check the 'Complaints' tab on the license record — this shows any filed complaints and their resolution status, which is more informative than just checking the active/inactive status.
What happens if a company works without a license in Arizona?
Contracting without an ROC license in Arizona is a Class 1 misdemeanor — up to $2,500 fine and 6 months in jail. The ROC actively investigates complaints and posts all disciplinary actions publicly on their website.
For you it also matters practically: insurers and future buyers treat unlicensed remediation paperwork as barely better than none.
Is a water damage restoration license different from a mold license in Arizona?
Arizona's CR-65 specialty license is the specific category for water damage restoration and household cleaning services — the only state in the U.S. with a dedicated water damage restoration license class.
Contractors performing structural reconstruction after water damage also need a B-1 (residential) or B (commercial) general contractor license from the ROC. For the extraction-and-drying phase, the industry standard to ask about is IICRC certification.
Is IICRC certification the same as a state license?
NoThey answer different questions. Arizona ROC CR-65 license applicants must demonstrate knowledge of water damage restoration standards — in practice, IICRC WRT and ASD certifications are the most recognized credentials.
Insurers in Arizona's Maricopa and Pima County markets widely require IICRC certification. The strong hire holds both: the state credential you can verify in the registry, and IICRC-certified technicians on your specific job.
I need a verified company fast — what's the shortcut?
One call: describe what you're dealing with and a certified pro serving your ZIP answers, with costs explained before any work starts. Then run their company name through the ROC License Lookup while you're still on the phone — a legitimate Arizona pro will happily wait the ninety seconds it takes.
