"Tom was wonderful and extremely thorough! He explained everything as he went along and I left feeling like I really knew the ins and outs of the property. He was extremely personable and very professional. He called to schedule and follow up prior to the date of the inspection. I felt confident in him during the entire process. I would recommend him to anyone."

"I received 3 quotes from 3 different company's who are certified in radon and Mason Dixon was the highest by $170.00 plus they have a gravel clause in their contract while others did not which could cause the price to go up another $500."

"This team was professional, as well as friendly and knowledgeableâ ¦gave us up front scenariosâ ¦ we didnâ t have to pay them before OR after the job was done (once the testing is done and we are SATISFIED, we are to pay the bill â ¦which was a little higher than the first company we contacted but the first company wanted payment up front and said nothing about OUR satisfaction). We were appreciative of the explanation of what was done and what WE needed to do to make sure the system was working properly. We got clear instructions on testing after installation. So far, so good! We are pleased."

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

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.

Installation typically takes 1-2 days, depending on the system and property layout.
