"This was a great experience from start to finish. They arrived on time got and got the work done with zero mess even though this involves drilling a large hole in the basement floor. The system did what it’s supposed to do and reduced radon levels to almost 0. I am very happy with this company and would highly recommended them.The price was great too."

"MaGen did an amazing job testing and abating our radon issue, which we weren't even aware of. Maryan's process was easy to follow, he performed work that was even beyond the agreed process (like making necessary fixes to our crawl space), and ensured that the radon system was working well. We went from having the meter read over 10 (pre-work) to under 1. If you're looking for someone that can handle your radon needs, get MaGen to do it ASAP!"

"Ohio Radon Specialists is a fantastic company to work with. They first sparked my interest by quoting me with the lowest price I received from radon companies in my area. My technician arrived on time and was very professional. My home had high levels of radon and Ohio Radon Specialists dramatically reduced the amount of radon in my home. I highly recommend them."

"Very thorough and detailed. They found cracks in the foundation where water had been seeping through, along with many electrical and roof issues. It's a good feeling, knowing that I have a pretty good snap shot of what the issues are with the house....so they can be fixed later. Definitely would recommend..."

"I just put a brand new roof on my home and i called a security first inspection to come out and make sure it was done properly and he found major issues with the ventilation the roofers put on so it was worth my money to call someone out that did identify problems and i got it straightened out before it caused an issuea,"

Radon Detection and Reduction questions, answered by experts

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

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.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.
