IICRC - Institute of Inspection Cleaning and Restoration Certification

IICRC - Institute of Inspection Cleaning and Restoration Certification holds a 5-star rating across 1,830 Google reviews, which stands out in Las Vegas where most homes were built around 1990 and the dry climate (27% relative humidity, 4 inches of annual rainfall) means mold is less common than in humid regions. That track record suggests homeowners have had positive experiences with their work. A standalone mold inspection in this area typically costs $200-$600, so you'll want to confirm pricing before booking.

Before you hire, know that Nevada requires mold remediation contractors to hold a valid license from the Nevada State Contractors Board - verify this at nvcontractorsboard.com. One important caveat: IICRC is listed as a mold inspector, and inspectors who also perform remediation work can create a conflict of interest under industry standards, since the same company profits from finding problems and fixing them. Ask upfront whether they do both inspection and remediation, and consider getting a separate inspection from someone who doesn't do repair work.
