It is very easy to test for radon. In order to determine if mitigation is needed, a self or professional test which results in a pCi/L of 4.0 or higher will require mitigation. 

"I highly recommend Chris Costello of Radon Control Services to mitigate your home of elevated radon levels. Chris is a qualified radon mitigation contractor with outstanding professionalism, reasonable rates, and courteous service. He arrived as scheduled, assessed the most appropriate location for the system to be installed with as little obtrusion as possible to the home's exterior, and promptly went to work. Within several hours the system was up and running and all areas were completely cleaned up and looking better than before he arrived! Thank you for your expert service!" - Joyce

​What is Radon?

Radon is a naturally occurring radioactive gas that has become the second-leading cause of lung cancer -- second only to cigarette smoke. Most soils contain uranium that, over time, decays to produce radium and polonium. Eventually, polonium is released with the radon, which creates a high toxicity level in the air and water that it infuses. Perhaps some homeowners are thinking they could recognize high levels of radon in their home. Unfortunately, radon is completely undetectable with any human senses. We cannot smell, taste, see, touch, or hear radon. Thus, it easily goes unnoticed. When this happens, everyone in the home becomes susceptible to contracting lung cancer. There are also very limited lung cancer symptoms. Even at that, they tend to lie dormant until becoming more severe. Radon exposure is the second leading cause of lung cancer. According to the World Health Organization, radon causes 15 percent of the world's lung cancer cases and kills 20,000 people each year. For those 20,000 people who have never smoked and have never been heavily surrounded by smokers, the lung cancer diagnosis is far from self-induced.
