"They were prompt, professional, and thorough in their review of the problem (results of a radon test revealing higher than acceptable levels of radon), coming up with a proposal for a radon mitigation solution, providing an estimate, accomplishing the work (blocking off possible radon entrances in the basement floor and installing a venting system), providing a visible means to monitor performance of the mitigation system once installed, explaining what they were doing, and answering all questions I came up with. <br />"

"Our existing system had been in the house 4 years and we had already had the fan replaced once. The previous company also used gutter pipe instead of PVC. We had Radon Experts come out to evaluate. Originally we were only going to replace the pipe since it was making so much noise that it was hard to sleep. Radon Experts told us that the type of fan that was being used was known for going bad and they recommended a different brand. It's been 3 months so far and no problem. They also replaced the pipe. They were quick efficient and very professional."

"Inspector was very professional and personable, and performed a very thorough inspection. He provided a detailed report (except for the radon test which requires more time) on the same day."

"Daniel performed radon testing and did a home inspection for a home we are purchasing. He was easy to contact and always quickly responded to our emails. He was very thorough with the inspection, encouraged us to ask questions, and explained everything he was doing. The day after the inspection, we received a detailed report (with pictures) that listed the discrepancies and suggested repairs. We received the radon test results 2 days later. Daniel was very professional and was great to work with. We highly recommend him for home inspections and would gladly use his services again. <br />"

"I waited a month before getting a test kit I called and was told there was something wrong with the Angies list orders but that I would be receiving a kit soon. It wouldve ben nice if they called me to tell me that though. The test results were quick and on par with other radon test I had done locally."

FAQs for radon gas testing projects in Fredericksburg, VA

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.
