"Andy from Tristate was a real professional. He was prompt, knowledgeable and the entire analysis was completed on time with an easy to understand report. We will use this company every 2 years to monitor radon. We could not be more pleased with Andy and Home Builder! John Seifert"

"Our radon system fan needed to be replaced and we were able to get that done the day after I talked to this company. Very quick and courteous service and didn't cost as much as we were anticipating."

"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!"

"Paramount showed earlier than the designated time. Which was just fine with us. They steam cleaned the affected area and scotch guarded the area as well. I happened to notice on the side of their van that they cleaned tile grout. They were willing to do it while they were here on my polished limestone bathroom and shower stall. The guy was friendly and professional and efficient!"

FAQs for radon gas testing projects in Cincinnati, 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.
