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: Can I do my own radon testing?

• <div><p>It is possible to <a href="https://www.angi.com/articles/how-to-test-for-radon.htm">test for radon yourself</a> using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family&rsquo;s safety, hiring an experienced professional to do the testing is usually the best option.</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. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.</p></div>

Q: What are the health risks associated with radon exposure in homes?

• <div><p>Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.</p></div>

Q: What costs are associated with radon detection services?

• <div><p>Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.</p></div>
