When selling a home, radon testing and mitigation can add unexpected costs. Many buyers now request a radon test before closing, which typically runs $100-$200. If levels are high, mitigation systems cost around $800-$1,500. Some states require disclosure, so it's smart to test early. This avoids last-minute surprises that could delay the sale or require negotiating who pays.
