Radon Detection and Reduction questions, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.

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

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
