Ask our Expert! Mitigating Radon for National Radon Action Month
January is National Radon Action Month, a perfect time for Southwest Longmont homeowners to take a closer look at an invisible but important health concern: radon. Colorado’s unique geology makes our region particularly prone to elevated radon levels, but with proper testing and mitigation, families can keep their homes safe. We spoke with Darren Corso, owner of Mile High Radon Control, to learn what every homeowner should know.
Q: Darren, what exactly is radon, and why is it such a concern in Colorado?
Darren: Radon is a naturally occurring radioactive gas released when uranium in the soil breaks down. You can’t see, smell, or taste it—that’s why testing is so crucial. Colorado consistently ranks among the highest radon states in the country. Many homeowners are surprised to learn that nearly half of homes in our area test above the EPA’s recommended action level.
Q: How does radon actually get into a home?
Darren: Radon travels upward through the soil and enters homes through foundation cracks, crawlspaces, sump pits, gaps around pipes—any point where the house meets the ground. Once inside, it becomes trapped and can accumulate to unsafe levels. This can affect homes of any age, size, or style.
Q: What’s the best way for residents to test for radon?
Darren: Testing is quick and affordable. Homeowners can pick up a DIY test kit or, for the most accurate results, hire a certified radon measurement professional. Winter is one of the best times to test because homes stay closed up, which helps provide a true picture of indoor radon levels.
Q: If test results come back high, what does mitigation involve?
Darren: A radon mitigation system is designed to vent radon gas from beneath the home to the outside air before it ever enters the living space. Most systems include a PVC vent pipe and a specialized fan. Installation typically takes just one day, and a properly designed system can reduce radon levels by 50–99%. They’re quiet, energy-efficient, and require minimal upkeep.
Q: What’s your top advice for Southwest Longmont homeowners this month?
Darren: Don’t wait—test your home. It’s one of the best and simplest ways to protect your family’s health. And if your results are elevated, mitigation is straightforward and very effective. My team at Mile High Radon Control is always happy to answer questions and walk homeowners through their options.
Radon testing and mitigation are simple steps that can make a meaningful difference. National Radon Action Month is a great reminder to check your home and breathe a little safer.
