"I used Radon Abetment Services LLC to install a radon system in my basement. John and his team were excellent and I highly recommend them to anybody with this need. John was able via video over phone identify where the system should go. His team was extremely professional and courteous. The installation took a day and the improvement in radon levels was remarkable. We would absolutely use them again."

"Ryan was right on time both for the dropoff and pickup for doing a Radon test of my basement. He's a great communicator and is very personable! He was able to give me a fair assessment of the test results this time, how they related to the results I had gotten at closing of my home, giving me all the info necessary to feel comfortable on my plan of action. I would highly recommend him!"

"Outstanding experience throughout the spectrum of repairs.  We were exceptionally pleased with overall costs and quality of workmanship.  Justin's crew was very professional and went above and beyond to clean the work areas at the end of each day.  Justin was always accessible via phone and email for questions that we had.
Great experience -- we'll definitely use Adam Contracting again in the future!

"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!!"

"I was very pleased with the service and work done by SWAT environmental. Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous. The system itself isn't inconspicuous but I feel safer knowing that our radon levels are significantly lower now."

Radon Detection and Reduction questions, answered by experts

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.

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.

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.

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