"Avert Radon LLC , specifically Chance, recently completed radon mitigation work at my residence, installing two systems. I typically refrain from writing reviews, but felt compelled to share my experience with Avert Radon LLC . I'm extremely satisfied with the results, as the radon levels are now virtually undetectable. Chance demonstrated exceptional professionalism throughout the process. The communication was excellent, and their meticulous attention to detail was also outstanding. Furthermore, their post-installation follow-up has been consistently excellent. I highly recommend this company without reservation. They are among the best service providers I've encountered. if I could give it more than five stars, I certainly would! "

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"The entire process went extremely well, and Hugh is a very pleasant person to work with. He came to the home a day early to set up the radon test. The day of the inspection led to a 35-page report that covered everything imaginable. He started at 9 a.m. and left at 3:15 p.m. after sitting down with us for nearly an hour to discuss all that he had seen, plus he had shown us various concerns during the process. We now know what needs to be done before the closing date, and can work with the realtors to make sure the home is safe and sound. Anyone needing a home inspection in the region should definitely consider this company."

"Terry was very professional and kept me informed on what was going to take place. He was very thorough and paid close attention to every detail. He made sure there were no tree roots or limb debris dumped into the hole that was filled in from the tank removal. He paid close attention to not damage any tree limbs as he worked his way around several large trees that were very close to the dig location. He had his crew rake and smooth the tire tracks from the grassy areas after he had completed the work and removed the heavy equipment. I was very impressed with his concern on leaving the property in good shape when the job was completed. <br /> Only concern was when Terry was late for the first meeting for the initial estimate. He also had to reschedule the actual planned work day but that was okay because he let me well in advance so I could adjust my plans. <br /> I would highly recommend Terry-Lynn LLC . <br /> Terry Miller is very knowledgeable and certified in his field. He always responded to my calls, or texts in a timely manner. His services are warranted and guaranteed. <br /> Thanks Terry for your professional service, <br /> Robin Claver <br /> 320 Tatum Rd. <br /> Olin, NC 28660 <br />"

FAQs for radon gas testing projects in Cashiers, NC

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.
