Radon is a naturally occurring radioactive gas that can seep into homes through cracks in foundations, basements, or crawlspaces. It’s odorless and invisible, yet prolonged exposure is the second leading cause of lung cancer. Because residential buildings can trap radon indoors, professional radon testing is essential to assess indoor air quality and detect dangerous levels before health risks develop.
Radon testing is essential for more homes than many people realize. Here’s who should consider scheduling a radon inspection and why:
Homebuyers – Test before closing to detect any hidden indoor air risks.
Homeowners – Regular testing ensures ongoing safety as radon levels can change.
Sellers – A test builds trust and avoids delays during real estate transactions.
New Construction Buyers – Even new homes can have elevated radon levels.
Basement Renovators – Disturbing soil or sealing spaces may increase radon buildup.
Health-Conscious Families – Prolonged radon exposure increases the risk of lung cancer.
The inspector selects the lowest livable level of the home for monitor placement and checks for proper test conditions.
To ensure accuracy, all doors and windows must remain closed (except for normal entry/exit) 12 hours before and during the test period.
A continuous radon monitor or approved test device is set in a central, undisturbed area to collect hourly air samples.
The test runs for a minimum of 48 hours, recording fluctuating radon levels over time to provide an accurate average.
After the testing period, data from the monitor is retrieved and reviewed for accuracy and consistency.
You receive a clear, easy-to-understand report showing the average radon level and whether it exceeds EPA-recommended thresholds.
Yes, windows and exterior doors should remain closed for at least 12 hours before and throughout the 48-hour testing period to ensure accurate results.
The device is placed in the lowest livable level of the home, ideally in a central area, away from drafts, high humidity, and direct sunlight.
Most tests run for 48 continuous hours to record hourly radon levels and calculate an accurate average.
Yes, you can use your HVAC system normally, but avoid whole-house fans, window fans, and fireplaces, as they may affect airflow and skew results.
A reading of 4.0 picocuries per liter (pCi/L) or higher is considered elevated by EPA standards and typically requires mitigation.
