There is no mold classification at the Arizona Registrar of Contractors, and the Department of Health Services publishes mold guidance without regulating the work. The credential that does apply is the general contractor licence, required once labour and materials exceed $1,000 or where a permit is needed at any value.
Arizona does back that licence with money: residential contractors must carry $200,000 of consumer protection, as a surety bond, a cash deposit, or participation in the Residential Contractors' Recovery Fund. That is worth more to a homeowner than a mold certificate nobody verifies.

Arizona issues no credential of its own, so the contractor's certification is doing all the work. Ask which body certified the crew and to what standard, and expect IICRC S520 for mold or S500 for water. Then ask for proof of liability cover, because in Arizona nothing else is being checked on your behalf.
With no state credential to pay for, Arizona pricing tracks the national ranges closely. That cuts both ways, because the cheapest quote and the most careful crew are indistinguishable on paper here.
Drying itself is priced the same in Arizona as anywhere else; the published national ranges are on the pricing page.
Metro guides for Arizona publish once three local facts can be sourced for a city: named operators, local flood risk and the county permit office. Until then the Arizona position above is the state-level answer, and the national guides below cover cost and process.
Arizona has no mold licence; what applies is the ordinary contractor licence, required once labour and materials exceed $1,000.
With no state credential, the contractor's own certification is doing all the work. Ask which body certified the crew and to what standard, and expect IICRC S520 for mold or S500 for water. Then ask for proof of liability cover, because in Arizona nothing else is being checked on your behalf.
