When you're selling your home, radon testing and mitigation costs can be a sticking point. A typical test runs about $150, but if levels are high, mitigation systems range from $800 to $2,500. Buyers often request these be handled before closing, so it's smart to test early and address issues upfront to avoid delaying your sale.
