Q: What level of radon is considered safe or dangerous?

• <div><p>No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.</p></div>

Q: Is a radon mitigation system expensive to run?

• <div><p>The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system.

Q: Do radon mitigation systems come with warranties?

• <div><p>Yes, many systems include warranties for performance. Confirm terms with your installer.</p></div>

Q: Why is radon detection important for residential properties?

• <div><p>Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.</p></div>

Q: Can I use my sump pit for radon mitigation?

• <div><p>If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.</p></div>
