Professional Radon Testing

Radon testing measures the concentration of radon gas inside a home. Testing is the only way to determine whether radon levels are elevated and whether mitigation may be recommended.

Types of Radon Tests

Radon tests are typically categorized as short-term or long-term, depending on the testing period and purpose.

• Short-term testing: Conducted over a period of 2 to 7 days and commonly used during real estate transactions
• Long-term testing: Conducted over 90 days or longer to better reflect average annual radon levels

When Radon Testing Is Recommended

• During real estate transactions
• Before installing a radon mitigation system
• After mitigation to verify system performance
• Periodically as part of ongoing indoor air quality monitoring
• When structural changes are made to the home

Understanding Test Results

Radon levels can fluctuate due to weather conditions, seasonal changes, and building characteristics. A single test represents conditions during the testing period and should be interpreted in context.

If elevated levels are identified, further testing or mitigation may be recommended.

Next Steps

If you are buying or selling a home, or if radon levels have not been previously evaluated, testing provides a clear starting point.
