ORF Home Inspections, LLC

ORF Home Inspections, LLC carries a 4.9-star rating across 1225 Google reviews, which matters in O'Fallon where homes built around 1999 face real moisture challenges. With 68% average humidity and 42 inches of annual rainfall, older houses are prone to mold issues that can worsen quickly if missed. That track record suggests the inspectors know what they're looking for in your local climate. A standalone mold inspection typically costs $200 to $600 in this region, so you're paying for expertise that can catch problems early.

Before you hire, verify that whoever inspects your home holds IICRC certification and carries appropriate general liability insurance. Missouri doesn't require a specific mold remediation license, so credentials matter more here. One important caveat: ORF Home Inspections is listed as offering mold inspection services. If they also perform remediation work, that creates a conflict of interest under industry standards - an inspector who profits from recommending fixes may lack objectivity. Ask directly whether they do both, and if they do, consider getting a second opinion from an independent contractor before moving forward with any remediation.
