Before you hire anyone for mold remediation in Columbus, verify they have IICRC S520 certification and current general liability plus pollution liability coverage. Ohio doesn't require statewide mold licensing, so these credentials matter. Also get a detailed quote upfront - typical projects in the area run $1,200-$3,600, so you'll want to understand what you're paying for and compare estimates from multiple contractors.
Columbus's humid climate (averaging 70% relative humidity and 39 inches of rain yearly) creates conditions where mold thrives, especially in older homes like many built around 1966. Rainbow Restoration of Westerville has earned a 5-star rating across 152 Google reviews, suggesting they understand local moisture challenges well. Before you sign any agreement, ask them to walk you through their specific assessment process and explain exactly what work they'll do to prevent the problem from returning.
