"Steve was awesome, he contacted me right away and gave me all the best options to mitigate the radon in my basement. He thoroughly explained how the system works and what we can do if the levels seem to be high in any other areas of my house. I highly recommend Steve and his company Certified Radon Solutions to anyone who is experiencing radon issues in their home!"

"It went fantastic. Scheduling wise the gentlemen at Rhino Radon were quick to respond to our inquiry via there website were I filled out a online questionnaire. Once speaking to Henry about the specifics of my home via phone and letting him no my situation. They were prompt in scheduling a date for installation to assure my radon problem didn't delay my ability to sell the home. From the time I filled out there questionnaire on there website till the system was installed and fully operational, all took place In one weeks time. I no from experience that these days the attentiveness and service Rhino Radon provided me can be difficult to find. Having recently just finished the process of building my own home in Malden and dealing with a wide range of company's and workers. It's the little things that stand out like personal treatment,responding quick to inquiries or concerns and of course taking the time to do things properly the first time around while still treating the home with respect. Rhino Radon came recommended to me via a friend and I couldn't thank them enough for steering me in the right direction for my radon mitigation needs. I would like to do the same to anyone currently searching for a radon company. If you want the job done right and a pleasant experience, look no further for your radon needs then Rhino Radon Services.

Radon Detection and Reduction FAQs, answered by experts

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.

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.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

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.
