Frequent Asked Questions about Radon Testing & Mitigation

Welcome to Milledge Construction Frequently Asked Questions section for residential and commercial radon testing and mitigation services. Radon, a colorless and odorless radioactive gas, poses a significant health risk when it accumulates indoors. This set of FAQs is designed to provide you with essential information about radon, its entry into buildings & homes, the importance of testing, and other crucial aspects. Whether you are a homeowner, business owner, or property manager, understanding the nuances of radon testing and mitigation is vital for creating a safe and healthy indoor environment. Explore the following questions to gain insights into the process, regulations, and best practices associated with managing radon levels in both residential and commercial settings.


Radon is a colorless, odorless, and tasteless radioactive gas that can seep into buildings from the ground. Prolonged exposure to elevated radon levels is associated with an increased risk of lung cancer.

Testing is crucial to determine if radon levels in a building are within acceptable limits. It helps identify potential health risks and informs the need for mitigation measures.

Radon can enter through the ground and water sources. It typically seeps through cracks in the foundation, gaps in floors, and other openings.

No. Radon can find a way into any home, new or old.

Usually not. Radon can permeate concrete even without cracks. Without a negative pressure underneath the slab it will most likely still be an issue.

In Iowa, it is against the code to have a cap or elbow at the top of the system. The fan is designed to shed water. The system will see anywhere from 3-5 gallons of rain water pass through it annually. Once the rain stops, the fan will begin drying out any water left by the rain. There should be enough air flow from the fan to prevent any leaves/debris from going down the pipe.

No, radon mitigation is applicable to both residential and commercial buildings. Any structure with radon levels above recommended limits should undergo mitigation.

While DIY test kits are available, hiring a certified radon professional is recommended for accuracy and reliability. Professionals have the expertise to interpret results and recommend appropriate mitigation measures.

The duration of mitigation varies based on factors such as the building size, construction, and the chosen mitigation method. Most residential mitigations can be completed in a day.
