Many O'Fallon homeowners assume all mold contractors are created equal, but Missouri doesn't require a specific mold remediation license. This means you could hire someone without proper credentials or insurance protection. When you're choosing a contractor, look for IICRC certification and verify they carry appropriate general liability insurance. SERVPRO of Western O'Fallon/Wentzville meets these standards and has earned a 4.8-star rating across 70 Google reviews from local customers.
O'Fallon's humid climate - averaging 68% relative humidity and 42 inches of rain annually - creates ideal conditions for mold growth, especially in homes like many in the area that were built around 1999. A typical remediation project in O'Fallon runs between $1200 and $3650, depending on the scope. Before you sign with any contractor, ask them to explain their specific process for containment and remediation so you know exactly what you're paying for.
