"Highly recommend. Elijah M was very professional, thorough in his explanations, and always on time. He installed a radon reduction system in our home and walked us through the entire process. We knew everything that was happening and how everything would work before he left. He also tested the system and explained how the test worked when he came back to check the radon levels. We are very happy with the service provided and will recommend Ohio Radon Services to anyone."

"I think they did a thorough job, however a small issue with the flashing was missed. It had been caulked which allowed water to seep through the brick. All in all, I had a good experience."

"Jon Helton and his son team member Zach were professional and thorough in their inspection while at the same time friendly and easy to talk to and ask questions. In addition to the inspection and samples he took for the lab, Jon gave us several helpful tips and suggestions for making the house marketable. I would definitely use Jon Helton and Home Team Inspection Service again and highly recommend them to anyone needing any type of home inspection, including buyers and sellers."

Radon Detection and Reduction FAQs, answered by experts

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.
