"They were prompt, efficient and courteous. They called to let me know they were on their way and cleaned up everything when they were done. They were supposed to explain something to me about some monitor after the installation, but they forgot. They did walk through how to do the radon test in another week. they also gave me a senior discount, which was definitely appreciated. Otherwise, their pricing was pretty much in the range with the other estimates I received."

"Zach Shipley of Clear Environmental took on the task of removing my extremely large inground swimming pool, filling the cavity and resodding the lawn. He and his crew were very professional in all aspects and he was very "hands-on" throughout the entire process. He was on-site for delivereies and to oversee the work and to keep me apprised of everything that was being done and how the job was progressing. It was a monumental job and he made it as painless as possible at a very competitive price. I would highly recommend Clear Environmental to anyone with a home or commercial project."

Radon Detection and Reduction FAQs, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
