St. John Environmental Consulting, LLC

Many Columbia homeowners make the mistake of hiring the first mold contractor they find without checking credentials. Since Missouri doesn't require a specific mold remediation license, it's on you to verify that any contractor you hire has IICRC certification and appropriate general liability insurance. St. John Environmental Consulting, LLC is worth considering, especially given Columbia's climate - with 68% average humidity and 43 inches of rain yearly, mold problems are common here. The company has earned a 5-star rating across 187 Google reviews, which suggests they've consistently satisfied local customers dealing with similar moisture issues.

Before you call anyone, know that a typical remediation project in Columbia runs between $1,200 and $3,650, so you can budget accordingly. When you do contact St. John Environmental Consulting, LLC or another contractor, ask them directly about their insurance coverage and IICRC credentials - and get it in writing before you sign any agreement.
