​EnviroHome conducts pre-purchase Indoor Air Quality inspections in Florida with equipment and expertise not found with your standard Home Inspector. Ensure prior to your new home purchase that your home does not have an IAQ issue that may reduce your home's value or have negative health effects.

Up until recently it was believed that there were only two sources of radon exposure – radon gas ground source seepage, and off-gassing of radon impacted groundwater. In the low ground source areas such as Tampa, it was generally assumed that radon was not a major concern and not one that would warrant mandatory testing associated real estate transactions, etc. Today we are finding highly elevated radon levels in many Tampa concrete building structures. Test results clearly show that the radon comes from the building materials and specifically from the poured concrete.

​

The problem is most significant in Tampa condominium, apartments, and high-rise structures where large volumes of formed in-place concrete are used and where large concrete surface areas are present in close proximity to building occupants living in the individual units.  â€‹

EnviroHome specializes in testing and mitigation of radon emanating from building materials. We provide testing, diagnosis, and full scale mitigation plans overseen by certified radon experts, licensed professional engineers, and licensed general contractors to ensure the radon levels in your property are at healthy levels. 

Tampa, St. Petersburg, and Clearwater Radon Levels by Zip Code

The Florida Health department has created a great database, linked here, of radon test results as reported by certified radon businesses and facilities per Florida Statute 404.056. This tool allows you to see the percentage of radon tests that returned greater than a 4 pCi/L result.  The EPA recommends homes and properties be mitigated if the level of radon is above 4 pCi/L.

​

Below are some of the zip codes in Hillsborough and Pinellas County over 10% that we were able to acquire. Last checked: July 17th 2022:

Per the Florida Department of Health: This radon data does not represent a scientific or statistical survey; therefore, it should be interpreted with caution. The data provides an indication of the radon potential within a zip code if a large enough and properly distributed number of buildings have been tested and reported for the area. This data cannot be used to predict the radon level for existing or new construction. Structural features, construction details, and ventilation operations differ from building to building and greatly influence radon concentration. Structures within the same zip code may have dramatically different indoor radon levels due to these differences. Inferring indoor radon levels for untested buildings based on indoor radon data from tested buildings is not possible.

Tampa, St. Petersburg, and Clearwater Public School Radon Results

The Florida Department of Health publishes radon test results for state licensed, regulated, owned, or operated facilities. You can find their information linked here and in the table below. If you do not see your school in the table below it's possible a new test has been submitted since we checked on July 31st 2022. Please check the database linked above for your school. If you still do not see your school the best course of action is to call the Radon and Indoor Air Program at 850-245-4288 or 800-543-8279 or email phtoxicology@flhealth.gov

Per the Florida Department of Health: Radon Testing is required for State licensed, regulated, owned or operated Facilities.  This requirement is the same for all buildings in facilities required to be tested for radon per Florida Statue 404.056.  Currently all buildings in a facility that are used by the clients of the facility are required to be tested twice, five years apart.  Once tested twice, testing is no longer required unless one of the triggering events occurs:

1) a building is subject to significant structural renovation or a change in facility operation equivalent to a building structural change, or
2) the facility legally becomes a new facility.  Examples of a legally new facility would be the issuance of a new license, or there could be a change in ownership or operator.  If a facility operator failed to complete the required testing in any building by the time it was due, the testing should be completed as soon as is practical.
