What Is Radon?

Radon is a radioactive gas that forms naturally in the soil and seeps into homes through foundation cracks and gaps. It's invisible, odorless, and tasteless — the only way to know your level is to test for it.

Responsible for approximately 21,000 deaths annually, according to the EPA. Long-term exposure to elevated levels is a serious health risk.

"We hired MaGen to do our Radon Mitigation, the whole process was easy and quick, the testing and abating. The owner is very sweet and does a great job at explaining and making sure everything is working. If you're looking for someone, MaGen is a great choice, and for sure would recommend!"

"MaGen did an amazing job testing and abating our radon issue, which we weren't even aware of. Maryan's process was easy to follow, he performed work that was even beyond the agreed process (like making necessary fixes to our crawl space), and ensured that the radon system was working well. We went from having the meter read over 10 (pre-work) to under 1. If you're looking for someone that can handle your radon needs, get MaGen to do it ASAP!"

"I have a large crawl space, and even though the job took longer than expected, he didn't cut any corners and made sure everything was done right. Very professional and thorough. Our radon levels went from 14 to 0. Couldn't be happier. Highly recommend."
