ServiceMaster

ServiceMaster holds a 4.7-star rating across 139 Google reviews, which is solid footing in Columbia's climate. With 68% average humidity and 43 inches of annual rainfall, homes here - especially those built around the median year of 1993 - face real moisture challenges. That rating reflects how local homeowners view the company's work in conditions where mold risk is genuine and ongoing. If you're seeing signs of mold or suspect moisture problems, ServiceMaster's track record suggests they've handled similar situations in your neighborhood.

Before you call, know that Missouri doesn't require a specific mold remediation license, so verify that any contractor you hire holds IICRC certification and carries appropriate general liability insurance. One important note: ServiceMaster is listed as both a mold inspector and remediation provider. Industry standards flag this dual role as a potential conflict of interest - an inspector who also does the cleanup work has financial incentive to recommend extensive remediation. For a mold inspection alone in this region, expect to budget $200-$600. Consider getting a standalone inspection from an inspector who doesn't perform remediation before deciding on any treatment.
