Mold Solutions

Mold Solutions carries a 4.9-star rating across 180 Google reviews, which matters in O'Fallon where homes built around 1999 face real moisture challenges. The area's 68% average humidity and 42 inches of annual rainfall create conditions where mold thrives, especially in older homes. That rating suggests the contractor has proven results with the exact climate and housing stock you're dealing with. Most remediation projects in O'Fallon run between $1,200 and $3,650, so you'll want a contractor who knows how to scope and price jobs fairly for this market.

Missouri doesn't require a specific mold remediation license, so before you hire, verify that Mold Solutions holds IICRC certification and carries appropriate general liability insurance. Ask to see both credentials in writing. This protects you if something goes wrong during the job. One important note: a high rating and insurance don't guarantee the lowest price, so get at least two quotes to compare scope and cost.
