How do I know if I need radon mitigation?

Radon gas is a silent health risk lurking in the shadows of our homes. This naturally occurring radioactive gas is odorless, colorless, and tasteless, making it virtually undetectable without the right tools. Yet, its presence is not to be taken lightly, as it stands as the second-leading cause of lung cancer in the United States. This post is an essential guide for homeowners to understand when radon mitigation is not just beneficial but necessary to ensure the safety and well-being of everyone residing in a household.

Introduction to Radon

Radon originates from the natural decay of uranium in soil and rocks. It seeps into our homes through cracks in the foundation, gaps around pipes, and other openings. Over time, radon levels can accumulate to hazardous concentrations, especially in well-sealed, poorly ventilated homes typically found in cooler climates. Awareness of radon and its dangers is crucial for the health of your family.

Radon Testing

Why test for something you can’t see, smell, or taste? Because knowing is half the battle. Home radon testing is the only way to identify whether you’re living with this invisible threat. Test kits are available for short-term (ranging from a few days to 90 days) and long-term (longer than 90 days) monitoring, providing a preview or comprehensive report of radon levels. Alternatively, continuous radon monitors offer ongoing surveillance of the radon levels in your home.

Understanding Radon Levels

Radon levels are measured in picocuries per liter (pCi/L). While no radon exposure is completely risk-free, the Environmental Protection Agency (EPA) has set an action level of 4 pCi/L. Above this level, the EPA recommends taking remedial measures to reduce radon exposure. The World Health Organization (WHO) suggests an even lower threshold of 2.7 pCi/L. Long-term exposure to high radon levels significantly increases the risk of developing lung cancer.

Signs You Might Need Mitigation

How can you tell if your home might have a radon problem without a test? There are a few signs and indicators:

  • Geographical Location: Certain areas are known for higher natural radon levels due to the underlying geology. Minnesota & Wisconsin have higher radon levels than much of the country.
  • House Symptoms: Frequent condensation on windows, musty odors, or chronic humidity issues can be signs of poor ventilation, which may trap radon inside.
  • Health Symptoms: Persistent respiratory problems, such as a cough that won’t go away, can sometimes be attributed to indoor air quality issues like radon—though you should consult a healthcare professional for a proper assessment.

However, these signs are not a surefire way to detect radon. The most reliable method is radon testing, which can conclusively determine if mitigation is required.

Importance of Professional Assessment

While home testing kits are useful, having a professional radon assessment ensures more accurate results. Certified radon professionals can conduct comprehensive tests and interpret results with expert precision, offering peace of mind or confirming the need for action.

FYI, Standard Water Control is certified to test and mitigate radon.

Mitigation Solutions

When a radon issue is identified, there are several mitigation techniques to consider, tailored to the specific needs of your home:

  • Ventilation Improvements: Sometimes, increasing the airflow in your home can reduce radon levels.
  • Active Soil Depressurization: The most common and usually the most reliable system, it involves installing a pipe and fan system to draw radon from beneath the home and vent it outside. This is the system Standard Water installs.
  • Sealing Cracks and Openings: Sealing entry points can help prevent radon from entering your home.

Whichever method is chosen, it is essential to have the radon mitigation system designed and installed by a qualified professional to ensure its effectiveness.


Understanding radon and its potential impact on your health is the first step toward a safer home. Homeowners should regularly perform radon tests and be on the lookout for signs that might indicate elevated radon levels. Mitigating radon isn’t just about improving numbers on a test – it’s about taking proactive measures to safeguard the health of those you love. 

If you’re concerned about the possibility of high radon levels in your home, don’t wait. Start with a simple home radon testing kit, and if the results are concerning, reach out to a professional for a definitive assessment. With radon, it’s better to err on the side of caution, and with the right approach, radon mitigation can be a straightforward and impactful process.
