Radon is a silent killer. It's a colorless, odorless radioactive gas which naturally occurs in the ground below us, and gets pulled into our homes, schools and businesses. Why should you worry about something you can't see or smell? Radon is the second-leading cause of lung cancer in the United States, with the US Surgeon General and the EPA estimating 20,000 Americans die every year due to radon exposure. Lifetime Radon Solutions is proud to be a locally owned and operated business that has been in operation since 1993! With years of experience and unmatched expertise we can help with any and all of your Radon testing and abatement needs. Get in touch today!

"I had never used Best Option Restoration before but had been referred to them by my neighbor. I was surprised by how quickly they responded (which was nice because I was pretty concerned). The same day, I had one of their managers out to my property to inspect the damage himself. He then reviewed the project with me, including the cost, the process for using my insurance, and the timeline. The work was completed on time. What I found most impressive was the communication throughout the entire process. I didn't feel like I was 'just another customer.' I have referred them to several within my neighborhood. I hope I don't have another broken pipe, but if I do, I know who I will call."

Radon Detection and Reduction questions, answered by experts

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.
