The Importance of Radon Testing in Real Estate Deals

When buying or selling a home, many factors come into play to ensure a smooth and safe transaction. One critical but often overlooked aspect is radon testing. Radon is a naturally occurring radioactive gas that can seep into homes through cracks and openings in the foundation. It is colorless, odorless, and tasteless, making it impossible to detect without proper testing. Understanding the importance of radon testing for real estate deals can protect health, save money, and provide peace of mind.


Why Radon Testing for Real Estate is Essential


Radon exposure is the second leading cause of lung cancer after smoking. The Environmental Protection Agency (EPA) estimates that radon causes about 21,000 lung cancer deaths annually in the United States. Because radon levels vary widely by location and even between neighboring homes, testing is the only way to know if a property has elevated radon levels.


For real estate transactions, radon testing is crucial because:


  • Health risks: Buyers want to ensure the home is safe for their family.

  • Disclosure requirements: Many states require sellers to disclose radon levels.

  • Negotiation tool: High radon levels can affect the sale price or prompt mitigation.

  • Peace of mind: Both buyers and sellers benefit from knowing the radon status.


Testing is a simple, cost-effective step that can prevent long-term health issues and costly remediation later.

How Radon Testing for Real Estate Works


Radon testing involves measuring the concentration of radon gas inside a home, usually expressed in picocuries per liter (pCi/L). The EPA recommends action if radon levels exceed 4.0 pCi/L.


There are two main types of radon tests used in real estate:


  1. Short-term tests: These last from 2 to 7 days and are commonly used during real estate transactions. They provide quick results but may be influenced by weather and ventilation.

  2. Long-term tests: These last more than 90 days and give a more accurate average radon level over time.


For real estate deals, short-term tests are most common due to time constraints. Certified radon testers place a testing device in the lowest livable area of the home, such as a basement or first floor. After the testing period, the device is sent to a lab for analysis.


If elevated radon levels are detected, mitigation systems can be installed to reduce radon concentrations. These systems typically involve venting radon gas from beneath the foundation to the outside.

The Role of Radon Testing in Negotiations and Disclosures


Radon testing can significantly impact the negotiation process in real estate transactions. When a test reveals high radon levels, buyers and sellers have several options:


  • Seller mitigation: The seller may agree to install a radon mitigation system before closing.

  • Price adjustment: The sale price can be reduced to account for the cost of mitigation.

  • Buyer mitigation: The buyer may accept the home as-is and install mitigation after purchase.

  • Walk away: In some cases, buyers may choose not to proceed with the purchase.


Sellers should be aware of local laws regarding radon disclosure. Many states require sellers to provide radon test results or inform buyers about radon risks. Failure to disclose can lead to legal issues and delays.


Buyers should request radon testing as part of their home inspection to avoid surprises after moving in. Including a radon test contingency in the purchase agreement is a smart move.


Practical Tips for Homeowners and Buyers


Whether you are selling or buying a home, here are some actionable recommendations to handle radon testing effectively:


  • Hire a certified radon tester: Professionals follow EPA protocols and provide reliable results.

  • Test during the inspection period: This allows time for negotiation or mitigation if needed.

  • Understand mitigation options: Systems typically cost between $800 and $1,500 and can reduce radon levels by up to 99%.

  • Retest after mitigation: Confirm that the system is working properly.

  • Maintain the mitigation system: Regular checks ensure continued protection.


For sellers, proactively testing and mitigating radon can make your home more attractive to buyers. For buyers, insisting on radon testing protects your investment and health.

Understanding Radon Risks and Regional Variations


Radon levels vary significantly depending on geographic location, soil composition, and home construction. Some regions have higher natural radon emissions, making testing even more critical.


Homes with basements or crawl spaces are more susceptible to radon infiltration. Newer homes built with tight construction may trap radon inside, increasing concentrations.


Knowing the radon risk in your area can help prioritize testing. Local radon maps and state health departments provide valuable information.


Regular radon testing is recommended even after mitigation because changes in the home or soil can affect radon levels over time.



Radon testing is a vital step in any real estate transaction. It protects health, ensures compliance with disclosure laws, and supports fair negotiations. Taking the time to test and address radon concerns benefits everyone involved in the sale or purchase of a home.
