"Called to ask about getting someone to come check on our radon system, which had stop working several months earlier. The person I spoke with, was friendly and very helpful. She was able to answer a few questions over the phone. She was also able to schedule someone to come out within the week. I was impressed that I received both an e-mail and phone appointment confirmation, the day before the technician was suppose to arrive. The technician showed up right on time, was professional and was able to diagnose the problem quickly. We needed a new fan for the system. Less than 30 minutes later, he was done and everything looks great. He left a radon testing kit that we will use in a week to make sure everything is working. Great experience and would definitely use them again in the future if needed."

"John did a great job. Our radon went down way more than I expected, to almost nothing. There were a couple of blips along the way, and they did everything to fix things with no trouble to me at all. I would highly recommend."

Radon Detection and Reduction questions, 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.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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.

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.
