"Radon Systems LLC did a great job. I had a radon level of around 6.5 in my basement for years, and finally decided I needed to address it. After receiving 3 quotes, I had Dave from Radon Systems come over to do the job. I initially was resigned to having the PVC pipe go up the side of my house, but Dave found a way to run the piping inside the basement and go thru the garage, with only 18" of PVC sticking up past the garage roof. Excellent! And now my radon level is around 1.0 to 1.5 all the time. The entire job took half a day, and Dave was clean, respectful and easy to work with. I absolutely recommend them."

Customers say: Quick response

"This is our first time buying a home and everything I read online made me feel I wasn't likely to find an inspector who actually took the time needed to really look at everything and give us a good inspection. I looked at 4 websites of inspection companies and chose Omega. The website provided information about Stuart and what his inspection covers. Our first call with him was pleasant and he was upfront about all the answers to our questions and the pricing. There were no surprises. He arrived early for the inspection, really took his time to examine, poke and test everything. He walked us through what he was looking at and explained any problems or lack of problems. He was very thorough and we'd recommend him to anyone! We'd also use him again if we have the need. You won't be disappointed with his service in any way!"

"I hired Erickson Foundation for radon mitigation. Job went smoothly. They communicated well, were very professional, and reviewed all potential options for the job with me. The system installation was done on time, professionally done, and well cleaned-up. The equipment is high quality, with the 10-year warranty being a big plus."

"Paul and Bill are both extremely knowledgable about all aspects of houses: construction, HVAC, plumbing, electrical, radon everything that I can think of and more.  They are also very nice and helpful. They are pleasant during the inspection, and happy to talk after the inspection and answer questions and make recommendations. <br /> This was the third inspection they have performed for me.  They may not be cheap, but the information is priceless. <br />"

"A&R was very responsive to our questions got back to us promptly with a quote.  Due to snow they had to reschedule our appointment, but they came right out as soon as possible.  Their work was excellent and we really appreciated that they left us with a radon test to allow us to test and make sure the system worked (which it did, with flying colors). <br />"

"The design that was proposed at the initial visit for the estimate ended up being problematic when the technicians came to do the actual installation. It was only with my help that they were able to solve the problem. I was convalescing from knee surgery so it was somewhat inconvenient for me to have to get up and out to figure out the situation. It ended up all right in the end; they did good work with no mess. The post-installation test confirmed a significant reduction in the level of radon gas in the basement of our house."

"The two techs were very professional and courteous. They installed a high performance radon fan and 3" pvc pipe with two different points of extraction in my basement. They had to work partially in a crawl space which made the install more difficult. They cleaned up all debris and left the work areas immaculate."

FAQs for radon gas testing projects in Wellesley Hills, MA

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.
