Radon Detection and Reduction questions, answered by experts

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.
