"Great job installing radon mitigation system in our newly purchased home. All work was done as promised and the system was installed in an inconspicuous location. There have been no problems, with very little noise from the system that we cannot even hear inside and the radon levels were successfully reduced.

"We used Elite for radon testing and it was positive and we put in radon system. We also used them when we purchased a new home to inspect and to test for radon. Radon was in normal range in new home. I don't remember exact prices for each test but was fair as was installation of radon system. Very thorough job and extremely professional."

"We have a concern about the level of radon in our basement apartment. Jesse came to our home and ran a radon test for a week. He was very thorough and informative. He addressed our concerns and answered many of the questions we had. At the end of the test he immediately sent us a report showing the radon levels for the week. We were very pleased with the service received."

FAQs for radon gas testing projects in Alpharetta, GA

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.
