"A1 and Andrew were great. Returned my call right away, gave me a fair bid, what I should expect, and a date to come out. They called ahead of time, and did quality work. Don’t hesitate to use them. I got lucky. I found out I had lung cancer and did a radon test. Don’t hesitate to do a radon test, and use A1 if appropriate. Thanks."

"Rapid Restoration was excellent to work with on a water damage issue I had discovered. They worked with me on cleaning an affected surface as well as air quality testing so we could have exact information for the best health of the home. They were able to get started the same day and were professional and wonderful to work with from the first phone call through the completion of the job. Chad is very knowledgeable and his crew was great. It turned out that we did not need to take additional steps for remediation because the diagnostics came back without concerns. I appreciated that this team had the skill and abilities to provide information and work up possible plans from "best case to worst case scenario" then take the most fitting action. We found a perfect result for the home at much lower cost than could have been the case without such an honest exam. I had two other companies out to look and Rapid stood out in terms of timing, communication, assessment, and an efficient plan. I couldn't be happier and will definitely call them again and highly recommend them!"

"We hired Radone, inc. for some follow-up work after a different contractor (Radon Squad, inc.) let us down. Sam did a great job assessing the installation and make the necessary repairs in a timely manner. His communication was excellent throughout. Highly recommend."

"John called me while I was reading reviews about TJ on angies list. He educated me about radon mitigation. I checked out a couple other companies and decided to go with TJ as they were able to come out the very next day and offered the best price. They arrived at exactly 9 am as they said they would. They evaluated the best method of mitigation for our house and explained their choices. They were done at the time they said they would be and cleaned up after themselves. They left a prepaid radon tester so that we could independently see they had brought the radon level down. Good results came back yesterday! I would highly recommend them!"

"I contacted Radiant Radon through Angi and Jonathan responded within minutes. We spoke over the phone the next day and I was given a firm price. The work was completed within a couple of days and Jonathan was super communicative and did a great job. I have an air quality monitor and the radon level dropped from 9.0 to below 1.0 within 24 hours. Overall - awesome service, great pricing and a great guy!"

"We recently had a radon mitigation system installed. When they ran the pipe for the radon fan out the side of the house they uncovered a pipe with asbestos that had previously been unreachable. I called AAA concerned and they were able to send someone to look at it the same day and completed the work that same week (I realize that might not always be possible). A small, quick job for $250, so I was very grateful they were able to squeeze us in and willing to take on the project. The first company I called was booked until April. I will call AAA first from here on on. They did great work and were all friendly and helpful."

"Justin was awesome. He seriously went above and beyond to explain things to me throughout the inspection. He was extremely thorough and he knows his stuff. He treated the inspection like he was inspecting his own home. He even took the time to show and explain how to fix a few minor things that were broken. I HIGHLY recommend using JJ Inspection. There were a few things I forgot to ask him to look at during the inspection and he offered to double check them when he went back to pick up the radon test."

FAQs for radon gas testing projects in Castle-Rock, MN

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.
