"Jeff inspected a home built in 1966 that we were looking to purchase. I have nothing but good things to say about Jeff. From my intial phone call to Jeff until his inspection was complete, I was very pleased with his professionalism and understanding of the job he was performing. At the conclusion of his inspection, he took the time to explain his findings and actually let me accompany him during a part of the inspection that I was having a hard time visualizing. The report he provided was great! I recieved it within 4 hrs of Jeff finishing the inspection. It provided detalied pictures with accompanying explanations. The report is accessible via the internet and able to be viewed, printed and forwarded at any time. I also needed the home tested for Radon, which like the inspection, was performed without any issues. I had the Radon report within 1 buisness day. Without Jeff's inspection, we would have missed critical repairs that needed to be taken care of before moving forward with buying the house. I highly recommend Jeff if you have a need for a home inspection/radon testing."

"We are out of state buyers looking to relocate to Tennessee. Tommy Kirby of 1st Choice Home Inspections completed our home inspection on the day and time arranged, as promised. He contacted us promptly afterwards with the results. He even advised us that due to what may be some costly repairs on the home, possibly causing us to reconsider the purchase, he would withhold submitting a well test that he performed, to his lab until we made the decision, saving us another $275. This is only the third time we've bought a home, but neither of our previous 2 home purchase inspections were as thorough and informative as this one. We most definitely will use his services again and highly recommend him."

FAQs for radon gas testing projects in Johnson City, TN

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.
