Q: Why is my radon mitigation system so loud?

• <div><p>Your radon mitigation system may be loud because it&rsquo;s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.</p></div>

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

• <div><p>No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.</p></div>

Q: How much does it cost to replace a radon fan?

• <div><p>The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.</p></div>

Q: Do radon mitigation systems decrease home value?

• <div><p>No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.</p></div>

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."
