"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."

"I bought a radon meter a few months ago and notice that the radon level in basement is very high. It seems the original radon mitigation system is not working. I went through a few different radon companies in the last few months. The original radon company who was hired by the builder did not even bother to show up to take a look at the issue. Dennis from Boston radon is simply amazing! He is extremely knowledgeable about radon and even gave me a lot of good advices for other issues in the basement beyond radon. I just have him re-installed a brand new radon system and will test the radon level very soon. Overall, I am very satisfied by his service and I do not think you will go wrong to ask for his help for any radon related issues. He is the man!!!!"

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."

"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."

"What impressed me first was that they knew what size system to install to meet our demand given that in the winter the water gets very cold and the ratings on the units are at 72 degrees not 34 degrees, so the next size up is needed.  They installed the system with no issues, I would say that if you want to make sure that the filter unit is solidly installed you should make that clear and have them bolt it to something so it won't tip over if its pushed.  I would say that you need to get a water analysis done either by this company or an independent, then give them the results to specify the system."

"I have worked with many contractors,plumbers,electricians, etc. in my time owning two homes. On here in New England and the other in Pembroke Pines,FL. These gentlemen from rhino radon services were deffinelty personable and proffesional I felt like my home was in good hands with this company. After calling around and having a job scheduled with another mitigation company I was blown off and left with a short deadline. Luckily after speaking with Henri from rhino radon they were able to squeeze me right in your schedule the very next day even though they had two other jobs scheduled they showed up at 5pm and still completed the job to ensure I met my closing date, if your looking for a standout and accommodating radon company I would say look no farther then rhino radon. I was very pleased with the service I recieved. HIGHLY RECOMMENDED

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

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.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.
