Q: What if radon is still high after mitigation?

• <div><p>You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.</p></div>

Q: How long can you go without a radon fan?

• <div><p>Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement.

Fortunately, radon systems require no downtime maintenance between fan changes.</p></div>

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

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>

If the fan is part of a larger radon mitigation system, the price may be higher.</p></div>

Q: How often should radon levels be tested to ensure safety?
