What Is Radon and Can It Be Found After Water Damage Events?

Radon is a colorless, odorless gas that forms when uranium in soil and rock breaks down. It can seep into homes through cracks in foundations, gaps around pipes, or openings in crawl spaces. Because you cannot see or smell it, radon is easy to miss without testing.

Radon levels vary by location and soil composition. Some areas have higher natural radon potential than others. Testing kits are available through local hardware stores or online, and they are simple to use. The results tell you the average radon level in your home over a set period.

Radon is the second leading cause of lung cancer in the United States, after smoking. When you breathe in radon gas, it can damage the cells lining your lungs. Long-term exposure at high levels is the main concern, so early testing is important.

If your radon test shows levels at or above the Environmental Protection Agency's action level, you should take steps to reduce it. This often involves sealing entry points and improving ventilation. See a doctor if you have health concerns related to radon exposure, but remember that radon is not a medical diagnosis.

If your radon test shows high levels, the first step is to retest to confirm the result. If it is still high, you can hire a qualified radon mitigation professional. They can install a system that draws radon out of the soil and vents it safely above your roofline.

Mitigation systems are often straightforward and can be effective. The cost depends on the size of your home and the specific system needed. Your insurance company may or may not cover radon testing or mitigation, so check your policy. Policies vary, and your insurer decides what is covered.
