"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."

"Appeared very knowledgeable regarding the problem I was having. Was on time and went right to work.. At this point I am very pleased with the results due to seeing less dust in the air and on furniture. The big test will come once I turn the furnace on this fall. I was informed to call them back if their was a problem. Again very pleased with their work at this time"

"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!"

"To the folks at Radon Be Gone and potential customers, Lengthy-but hopefully insightful Recently I learned that radon was present in my house and the intelligent thing to do is to have it mitigated. This occurred at the onset of the pandemic and the Governor's briefings and closures. I had read plenty of positive reviews about Radon Be Gone and they came personally recommended from a couple people I trust. At the time Radon Be Gone was not operating until they felt they had a great grasp of safety protocols for their staff and customers. I did have a few other companies come out, take a look, and provide a quote but my gut told me to wait if possible for Radon Be Gone to be operational. I spoke to Portia several times and she was very knowledgeable, reassuring, and answered a lot of questions I had, now that I had some time to learn about the gas itself and how companies mitigate it. Brad came out and did an honest assessment and again answered a host of questions. Due to previous reviews, their treatment of me, and the similar price to other companies, I chose Radon Be Gone. I was a bit nervous because I had finished the basement a couple years prior. For anyone that plans to finish their basement, check for Radon first. You have less options once you finish it. The day the job was to be completed, the vehicles were in my drive a few minutes early, which I liked. The guys: Larry, Walker and Ian were all very cooperative and professional. I was able to watch and learn without feeling like I was snooping. The holes in my side brick and facial wall and the foundation were precision. We couldn't have picked a better spot for the system. It is unobtrusive in the utility room and is not visible from the sides of the house that matter. They explained the system and how it works and some small other need to know items. They caulked all the exterior hardware and sealed and cleaned everything. For those of you that may be concerned about their Covid safety protocols- I was very comfortable with how they operated. Post installation of the equipment, they retested the Radon Levels in my house and I was not only under the accepted level, but significantly under. The report of the test and other details were provided in a very timely manner. As a matter of fact the gentleman, forgot his name, (sorry) text me the results immediately. I know this is probably a lengthy post, but hope it provides useful insight and my recommendation of using Radon Be Gone if you need to have Radon Mitigation."

"Absolutely professional. Tyler came out exactly on time. His co worker/partner set everything up and explained the process and worked with our schedule. Pricing was VERY affordable and for a job done exceptionally well and clean. I reccomend getting the levels tested in your basement as over time this can be detrimental to ones health. If we have any issues in the future, I will be using Ohio Radon Specialists for all of our mitigation needs."

"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,"

FAQs for radon gas testing projects in Columbus, OH

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
