My name is Aleksey Levchenko, I’m a local licensed plumber specializing in new construction. I started to noticed more and more often that radon gas is in high quantities in most homes and needs to be taken care of. After doing some research, not only is it a concern but the availability and price to mitigate and test radon is not reasonable in our area. I decided to get nationally certified to measure and test radon and in the case of high quantities, my experience as a subcontractor plumbed allows me to mitigate in the most professional way.

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.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.
