We have been certified for radon testing since 1999 and have performed more than 25,000 radon tests throughout Southwest Florida, including thousands of tests completed during residential and commercial real estate transactions.

​

Radon testing is commonly recommended during the home buying and selling process because elevated radon levels cannot be detected without specialized testing. Identifying radon concerns before closing allows buyers and sellers to make informed decisions regarding mitigation, repairs, and overall indoor air quality.

​

If you’re not familiar with radon, it is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. Because the air pressure inside a home is usually lower than the pressure in the surrounding soil, homes can act like a vacuum, drawing radon gas inside through foundation cracks, slab penetrations, and other openings.

​

While radon is present in the air we breathe every day, elevated indoor concentrations can become a serious health concern. According to the U.S. Surgeon General, radon is the second leading cause of lung cancer in the United States and is estimated to contribute to tens of thousands of lung cancer deaths each year.

​

The U.S. Congress established a long-term goal that indoor radon levels should not exceed outdoor levels, which average approximately 0.4 pCi/L. The EPA recommends mitigation when:

​

• One long-term test shows radon levels of 4.0 pCi/L or higher, or

• The average of two short-term tests is 4.0 pCi/L or higher

​

With modern mitigation methods, radon levels in most homes can typically be reduced to 2.0 pCi/L or lower. Homeowners may also wish to consider mitigation when levels fall between 2.0 and 4.0 pCi/L.

​

For real estate transactions, our testing procedures follow industry protocols designed to provide accurate and defensible results within the timelines often required for inspection periods and contract contingencies. We work closely with homebuyers, sellers, real estate agents, property managers, and remediation contractors to help ensure a smooth transaction process.

​

In Florida, radon reduction systems commonly involve introducing controlled fresh air into the home using systems such as:

​

• ERV (Energy Recovery Ventilator) systems

• VAV (Variable Air Volume) systems

​

These systems can also help improve overall indoor air quality by reducing airborne contaminants and volatile organic compounds (VOCs) released from building materials, paints, adhesives, furnishings, and other household products.
