"Radon is not something I knew much about, but after purchasing an AirThings air sensor and tracking the radon levels in my basement, I felt like this was causing some of my wife's breathing issues. I found two different companies on HomeAdvisor.com. Radon Systems LLC was a lot cheaper than the second company I met with. I spoke with Lori and she gave me a lot of great information about radon. She sent me an estimate very quickly and after making a decision to hire them, got me an appointment within a week. Nick came to do the work. He was very professional, wore a mask the whole time and did a very neat job. He cleaned up both inside and outside before he was done. I would highly recommend this company to my family, friends, and others looking for a radon mitigation system. Thanks Radon Systems LLC."

"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!"

"The consultation appointment was setup quickly, the salesperson was genuinely nice and took time to answer all my questions. The company itself is well organized, everyone was on the same page for the whole process. The installation for our radon mitigation system went smoothly. The crew was pleasant and did a great job."

"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."

"George and his team were extremely friendly and professional. This is a good group of people. Courteous and thoughtful, they were able to do a complete installation of both systems from scratch in about 6 hours.
The new radon remediation system (Bubble Up) has the added benefit of boosting the fixture pressure in the house to city level or better (60-75psi) as well as completely resolving the pH level of the water.
The cost was slightly lower than the other two quotes we received, partially due to the fact that Absolute offered a "multi-system" discount since two systems were going in at the same time.
If in your service area, I would highly recommend George Doumit of Absolute Water System.

"It went fantastic. Scheduling wise the gentlemen at Rhino Radon were quick to respond to our inquiry via there website were I filled out a online questionnaire. Once speaking to Henry about the specifics of my home via phone and letting him no my situation. They were prompt in scheduling a date for installation to assure my radon problem didn't delay my ability to sell the home. From the time I filled out there questionnaire on there website till the system was installed and fully operational, all took place In one weeks time. I no from experience that these days the attentiveness and service Rhino Radon provided me can be difficult to find. Having recently just finished the process of building my own home in Malden and dealing with a wide range of company's and workers. It's the little things that stand out like personal treatment,responding quick to inquiries or concerns and of course taking the time to do things properly the first time around while still treating the home with respect. Rhino Radon came recommended to me via a friend and I couldn't thank them enough for steering me in the right direction for my radon mitigation needs. I would like to do the same to anyone currently searching for a radon company. If you want the job done right and a pleasant experience, look no further for your radon needs then Rhino Radon Services.

"Dennis contacted me several times by phone ( we were away traveling, I appreciate his effort). We set a date and time. It was a long drive for him. He arrived on time. He completed the work in a professional manner. The roof looks great. I'm completely satisfied with the work. Dennis couldn't have been a nicer guy.

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
