"We used Radon Abatement Services for our basement. The radon levels were slightly over the EPA recommended limit. We mitigated the radon as part of a larger basement renovation. Radon Abatement Services worked with our General Contractor and did a great job. Radon levels are vastly reduced now as a result of their work."

"After my basement test come back with significantly elevated radon, I contacted radon abatement services at the recommendation of a neighbor. A day and a half later, they were on site. While performing the initial walk through, the experienced and thoughtful professionals adapted their plan to utilize my sump pump. This was an effective strategy as it addressed the main source of radon and concealed the system in completely unfinished space. I just received my post mitigation radon results, and the system is working phenomenally. To sum it up, I was blown away by the responsiveness, thoughtfulness, and reasonableness and can't say enough positive things about this company. I don't ever post reviews, but in this circumstance I absolutely had to."

"I scheduled the radon testing with Bill. He was very thorough and accommodating. Bill agreed to meet my real estate agent at the property to set up the testing equipment. As promised, the test results were provided in a report format and after 48 hrs. Great service."

"Justin was quick to respond and very polite. The job was a tad bit pricey but he explained about the extra cost of using a 28 ft plus ladder. Which I was happy to pay to get the repair done. The job was done in only two days after I made the request. And everything looks as it should be. Job well done and I will definitely refer him and use Adams again.

"Chris was very professional on the phone and it surprised me that, for such a low price, I was getting as much as I did! MA CARRES is a FHA 203k qualified inspector (though I only hired him as a home inspector) AND a Realtor so I got a little bit of everything when he and his employee came. The fact that they are retired firefighters was a bonus as I had some questions about darkened wood and they let me know where the CO2 detector should really be located for best effect. I definitely will use MA CARRES in the future!!"

"We were able to schedule an appointment with Mr. Lindsay on very short notice. I called him on a Friday and was able to schedule an inspection with him for the following Monday. He was punctual, polite and professional. He welcomed us to follow him around during the inspection and ask questions. He was also receptive to hearing our particular concerns about the home and addressing those concerns in his report in addition to his findings. Before leaving the home, Mr. Lindsay took the time to review his list of issues with the home with us to make certain nothing was missed for his final report. He completed and sent us the report very quickly (within 24 hours). The report was neat and detailed with pictures clearly illustrating any/all issues with the home. His work was also very affordable. I would definitely recommend him to a friend or family member in the future."

Radon Detection and Reduction questions, answered by experts

Installation typically takes 1-2 days, depending on the system and property layout.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.
