How Can We Help?

We are here to help you learn about, test for, and reduce radon levels. We make it possible to enjoy your home, school or workplace worry free of the dangers of radon gas. In 2007, one of our founding partners, Len Gieck, learned about the danger of radon gas. He tested his home and discovered unsafe levels. With a daughter living in the basement of his home, he researched how to fix his home and reduce the levels. From then on, it became Len’s mission to help others navigate solutions to radon gas by providing trusted radon mitigation solutions.

What is Radon ?

Radon is an odorless, colorless gas that causes lung cancer. It is present everywhere in the atmosphere, but in buildings it can build up to levels that are unsafe. The only way to know how much radon in your home is to conduct a simple test using a radon test kit.

I was very impressed with Radon Controls Inc. Not just their responsiveness and professionalism but their follow up. They never missed a

beat with following up on post work testing and clearly have an organized and mature business that works. These guys are great I would highly recommend them. ~ A. Kolozetti
