IDPH is explicit that it does not license individuals to perform mold assessments or testing. What Illinois has instead is the Mold Remediation Registration Act, Public Act 103-0893, which requires firms providing mold remediation to register with IDPH and show active third-party certification and evidence of financial responsibility.
The practical test for a homeowner is therefore two-part: is the firm registered with IDPH, and which body certified it. IDPH points to ACAC, IICRC and NORMI. A registration number is a real thing you can ask for; a claim of being "certified" with no issuing body named is not.

Registration is a number you can ask for and look up with Illinois Department of Public Health (IDPH). Ask which body issued the third-party certification behind it as well, since the registration rests on that certification staying active. A claim of being certified with no issuing body named is not a credential.
Registration does not set prices, so Illinois pricing tracks the national ranges. What it changes is who you can hire: an unregistered firm working for compensation is operating outside the Act.
Drying itself is priced the same in Illinois as anywhere else; the published national ranges are on the pricing page.
Metro guides for Illinois publish once three local facts can be sourced for a city: named operators, local flood risk and the county permit office. Until then the Illinois position above is the state-level answer, and the national guides below cover cost and process.
Illinois registers mold remediation firms rather than licensing them, and requires third-party certification to register.
