When you're looking at a contractor with 60 Google reviews and a 4.9-star rating, you're seeing enough feedback to spot patterns about their work quality and customer service. That said, reviews alone won't tell you whether they're properly licensed or insured for mold work. In Columbus, where older homes built around 1966 are common, mold problems can be serious. Ohio Technical Services, Inc. should be able to show you IICRC S520 certification along with proof of general liability and pollution liability coverage before you hire them.
Columbus gets plenty of moisture - averaging 70% relative humidity and 39 inches of rain yearly - which means mold remediation isn't cheap. Most projects in the area run between $1,200 and $3,600 depending on the scope. Before you commit to Ohio Technical Services, Inc. or any contractor, ask them to provide a detailed written estimate and proof of their insurance coverage. Don't sign anything until you've verified those credentials in writing.
