Mammoth Restoration holds a 4.8-star rating across 161 Google reviews, a strong track record for a mold remediation contractor serving Flagstaff homeowners. Given the region's 48% relative humidity and 22 inches of annual rainfall, mold risk is real, especially in homes built around the 1991 median age. That rating suggests the company knows how to handle moisture problems common to older Flagstaff properties. Most remediation projects in the area run between $1,100 and $3,400, so you'll want to get a quote to understand costs for your specific situation.
Before you hire, confirm that Mammoth Restoration holds a valid ROC (Registrar of Contractors) license, which Arizona requires of all mold remediation contractors. You can verify license status at azroc.gov - it takes just a few minutes and protects you from unlicensed work. Don't skip this step, even with strong reviews; licensing ensures the contractor meets state standards and you have recourse if something goes wrong.
