Radon is an invisible radioactive gas that can enter homes from the soil. Testing is the only way to know the concentration in a specific property, and mitigation systems are a common response when results are elevated.
Testing belongs in the inspection conversation
A buyer can discuss radon testing with the inspector and agent, including the device, test duration, placement, property conditions, and how the result will fit into the offer timeline.
One result is information, not a character judgment
An elevated result does not mean a house is uniquely bad. It means the parties need to evaluate the result, the test conditions, possible follow-up testing, and the cost and design of mitigation.
Mitigation is usually a defined project
A qualified contractor may install a system that draws soil gas from beneath the foundation and vents it outside. Design and cost vary with the home, so obtain property-specific information.
Put the agreement in writing
Whether the seller installs a system, provides a credit, adjusts price, or takes another approach, the final terms should be documented clearly in the transaction paperwork.
