"They were very nice and professional, but everything they said was wrong with the house I purchased, was wrong. Said there was a small gas leak on the water heater, spent $275 for a plumber to tell me nothing is wrong. They said the furnace was in good condition, but couldn't guarantee how long it would last because it was over 50yrs old. They were wrong again, there was a crack in the heater exchange, so unless we are a fan of carbon monoxide we can not use the furnace. So basically I paid $425 for them to turn things on and not actually inspect anything."

"Eric contacted me shortly after searching Angie's List. I described what I needed, a radon mitigation system, and he provided a written estimate via email. Much lower than what I expected. Eric was able to come out in a few days and install the system. Installation time was about 3 hours. No additional charges. He returned to the house three days later to retrieve the radon monitor and showed me the current reading of 1.0 pC/l, well below the 11.0 pC/l from a prior test. A formal report was emailed the same day; the avg reading was 0.8 pC/l. I highly recommend hiring Radon Fix."

"We called Radon-X because Radon Technology Inc. (RTI) did not return our call for service. RTI installed the unit originally and we called them first because their number was on the unit. We called RTI twice and they failed to follow up with us - and still have not responded back! We called Radon X and their response was immediate. Mr. Busch was prompt and found the problem immediately. He didn’t even charge us for his service call. We appreciated his honesty and experience and Radon X will be the only call we make next time. We highly recommend RADON X! Steve and Sandy Heffner"

"He saved me from making two very questionable purchases. If you're there while he performs the inspection you'll learn a lot about home maintenance and building code. Pay attention to what he tells you. The reports that he issues are *very* detailed and are designed not just to allow you to make an informed decision on a home purchase but also to educate. I feel that I got my money's worth, and then some. If you buy a home and regret it afterward, you're going to pay *much* more than one or two inspection fees!"

"The services went very well.?The inspector was just really knowledgeable and he pointed out a lot of stuff that we hadn't realized that there were original parts to the home that were built but weren't to the current code, that we knew to get them fixed for safety purposes and everything. They were a little more expensive than ones we've had before, but I think it was worth the money still."

"Extremely responsive, efficient, and professional. Very quick response to my phone call. Explained all the details of the process for radon mitigation. They came out within a day or two to provide an estimate, and they were able to perform the service that week. I highly recommend them for radon mitigation. ?On future houses in need of mitigation, I will definitely be using them again."

"They were here for about 3 or 4 hours. The air quality is so much better. They liked interacting with the kids. They were really nice. My mom actually picked them. They showed up extremely prompt. They were here like 7:59 a.m. They were courteous and reliable. They were kind of expensive to me."

FAQs for radon gas testing projects in Dayton, 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.
