Kelley Klean

Kelley Klean holds a 4.9-star rating across 202 Google reviews, which matters in Columbia where homes built around 1993 face real moisture challenges. The area's 68% average humidity and 43 inches of annual rainfall create ideal conditions for mold growth. That consistent rating suggests Kelley Klean has proven experience handling the mold issues that older homes in this climate tend to develop. Most remediation projects in Columbia run between $1,200 and $3,650, so you'll want a contractor who understands local conditions and delivers reliable results.

Missouri doesn't require a specific mold remediation license, so verify that any contractor you hire carries IICRC certification and appropriate general liability insurance before signing anything. These credentials show they've met industry standards and can protect you if something goes wrong. Ask to see proof of both before booking, since licensing gaps are common in this field.
