"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."

"Beatty home inspections was awesome to work with! Being a first time home buyer, we really didn?t know much about the process or what to expect. Chris?s expertise not only made us more knowledgeable about it ourselves, but put our mind at ease that the issue would be fixed. The issue was in fact, fixed. I would recommend him tenfold to anyone looking to get a radon mitigation system put in."

"Shawn was very professional, timely, and informative. He performed a thorough/comprehensive full house, radon, and termite inspection on my new construction home. The report was extremely helpful for negotiating with our builders. Shawn found problems that their inspector had not. He even made ergonomic recommendations. Shawn was very prompt too. We had our inspection report the same afternoon as our inspection. I also found that he was extremely reasonable price wise when compared to similar professional inspection companies. I definitely recommend that you use Eagle Eye Inspection services! Thank you Shawn!"

Radon Detection and Reduction questions, answered by experts

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

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.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
