"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."

"We are first-time home buyer. We considered to buy a condo and found him on Homeadvisor. He is fantastic and experienced home inspector. He helped us identify one safety issue and a solid list of minor issues within the unit. He also explained in great details of how to maintain various apartment appliances. Not to mention that he charges fair amount of service fee, which is significantly lower than the market price. We'd definitely recommend him for all home buyers."

"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.

"We feel confident in recommending the home inspection services of Mr. Robinson. When looking for a person perform the inspection we relied on Mr. Robinson’s qualifications (member, ASHI), his experience within the location of our prospective home (i.e., familiarity with older homes in the Dedham, West Roxbury, JP and Boston/Roslindale neighborhoods) and his wealth of experience in working in and with older homes. As a licensed construction supervisor, he has consulted in some of the finest homes in Beacon Hill as well as many moderately priced homes surrounding the Boston area. We wanted a person who would be able to strike a reasonable balance between the cosmetic concerns of some older dwellings and those of a more serious nature. Mr. Robinson did just that. While our potential home needed some ventilation improvement in the attic and structural work for a detached garage, his emphasis on the safety and integrity of the house took center stage. He reaffirmed the value of our purchase price while giving us cost estimates for the recommended improvements. We wish to employ local contractors and Mr. Robinson was able to provide us the contact information for such. His wisdom, professionalism and guidance was invaluable."

"DENNIS (OWNER) WAS VERY PROMPT AND THE ROOF WAS CLEARED PRETTY QUICKLY. HE WAS A LITTLE GRUFF AT FIRST, WHEN HE WAS AFRAID I CALLED HIM ALL THE WAY OUT JUST TO GIVE ME ADVICE (HE DIDN'T GET THE FIRST-TIME HOMEOWNER HAND-HOLDING THING, I GUESS), BUT OTHER THAN THAT WAS FRIENDLY. HE WAS HAPPY TO GIVE ADVICE ON UPCOMING ROOF REPAIR NEEDS, AND SEEMS LIKE HE WORKS WITH OWNERS RATHER THAN AROUND THEM. UNFORTUNATELY, THEY WERE MORE THAN ASSIDUOUS ABOUT REMOVING ICICLES, AND SOME SHINGLES AND SIDING WERE (VERY MINORLY) DAMAGED IN THE PROCESS."

Radon Detection and Reduction questions, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

Yes, many systems include warranties for performance. Confirm terms with your installer.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.
