"TESTING FOR ASBESTOS I need to make sure people know about a man named Jeff Miller Owner of Scope Environmental. I wanted to have my basement checked for Asbestos. This man was absolutely the nicest person. Jeff is a professional, who explained things extremely well and in detail, offered positives suggestions, and extremely knowledgeable. Oh, and extremely honest and helpful. If you ever want to have your basement checked for Radon or Asbestos or Mold, please call this nice man who has a vast amount of experience and knowledge on these three issues. His phone number is 314-220-1810. His pricing is very reasonable and he is Certified in the State of Missouri which is a requirement by the State to do testing. He sure put my mind at peace."

Radon Detection and Reduction questions, 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.

Yes, many systems include warranties for performance. Confirm terms with your installer.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
