Operation Restoration

Operation Restoration carries a 4.9-star rating across 83 Google reviews, which matters in Columbus where the climate works against you. With 70% average humidity and 39 inches of annual rainfall, plus most homes built around 1966, mold finds plenty of opportunity in older construction. A contractor that consistently earns top marks from local homeowners has proven they can handle the moisture challenges specific to this area. You're likely looking at a remediation project cost between $1200 and $3600, so that track record is worth paying attention to.

Before you hire, know that Ohio doesn't require a statewide mold remediation license, so you'll need to verify credentials yourself. Ask Operation Restoration for IICRC S520 certification and proof of both general liability and pollution liability coverage. These protections matter because mold work involves real risk. Once you confirm they have the right credentials and insurance in place, you'll have solid ground to move forward with confidence.
