"Mark Pierce was very helpful and thorough. We are moving from TX to NC and could not be there for the inspection but Mark called and went over everything he found concerning with us. We used them for the home inspection, water test and radon test and were very happy with their service."

"This is the third time I've had Joseph perform an inspection for me in the last three years. You will find my previous reviews elsewhere on Home Advisor. His first inspection saved me from purchasing a house with many issues that the sellers failed to disclose. They initially declared that they would not negotiate on anything, but when he was finished they were rushing to backpedal and begged me not to cancel my offer. The sale was cancelled the same day he was done with his inspection. His second inspection ended in my purchasing my current home, and after three years I remain very satisfied with the purchase. This latest inspection was done in order to renew my insurance. I was asked for a 4-point but based on his expertise, he recommended I also do the wind mitigation since it might be asked at some point. Turns out, it will be needed after all, and his recommendation saved me from having to do this twice. So I have used Joseph's services for years, and he's always delivered even if asked to do so in short notice, with time constraints, while being flexible and accommodating when it comes to scheduling the work. I haven't had reason to complain about his services yet, and I will continue to call him first whenever I require any sort of home inspection."

"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! "

"Biotek is the best, most compassionate company I've ever dealt with. All the employees were top professionals with a very kind heart & ever so helpful. They answered all my questions honestly & were concerned about my health. All were knowledgeable, well trained, courteous, & performed the testing & remediation efficiently. They blocked off the place where the mold was found & protected me from any mold spores or mycotoxins the the remediation could stir up. They brought huge air scrubbers to my house to suck up all bad stuff in the air & used a special vacuum cleaner to clean the carpets, as well as cleaning the furniture. They thoroughly took every precaution & measure to get rid of all toxins & poisons from the mold that have made me so sick. I am so grateful for Biotek & pray for all in the company everyday. May God bless them more than they could ever ask or think."

"Greg Peterson did an amazing job. He provided a thorough proposal with a reasonable estimate for his work. I felt comfortable immediately and requested that he do the work. He arrived on time, explained the work he was doing, and left the work area neat on completion. He explained what he expected from his work, and the results reflected that. He was extremely professional. I feel confident that my radon issues are no longer a problem. He also does home inspections and I only wish I had had him do our inspection when we purchased the house. We are considering having him come back and doing an inspection of our house so that we can feel confident that we know our house well. I feel lucky to have found this professional."

"<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 />"

FAQs for radon gas testing projects in Asheville, 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.
