"adon After I contacted him, he responded promptly.  While evaluating the area that needed radon mitigation, he called to discuss an area that had not been evaluated by inspectors (not affiliated with him).  After accepting his price, we agreed on the day for the installation.  During the installation, he was respectful and communicative.  After completing the installation, he provided written warranties for me and the buyer.  I highly recommend Keystone Radon Mitigators.

"Bill was very responsive and did a very thorough assessment of the water damage. He provided a detailed estimate for the work at a fair price. My homebuilder agreed to repair the damage and I didn’t need to hire Flood Crew LLC. I would hire Flood Crew LLC in the future if needed."

Radon Detection and Reduction FAQs, answered by experts

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 a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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

Installation typically takes 1-2 days, depending on the system and property layout.
