"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."

Customers say: Quick response

"Ted Riddick did an excellent job of performing a mold test in our basement, at the buyers request. I was very leary at first, because we recently cleaned the carpets and were concerned and/or confused that mold could be in our basement. We certainly would have known if we had mold in our basement or water coming causing a mold situation. Needless to say no mold was found, and my worries were alleviated. Mr. Riddick is a seasoned inspector, with a deep knowledge all areas of home inspections. He was professional, kind, did a great job."

"Tommy, Paul and crew did an excellent job with my radon remediation and installation of a new attic stairs. They tailored the exhaust piping for my radon removal so the only thing that showed was the exhaust vent, which they painted to blend in with the roof. The test results after remediation was only 0.4 pCi/l. The very low results is a testimony for their outstanding work. They were very friendly and accommodating. They always strived to exceed my exceptions, which they did. I highly recommend Atlantic Radon."

"Very friendly, professional crew from the local area. I got the quote from Peter and had the system installed within a week. Very clean and solid installation. Time will tell how effective it is (still need to wait 48 hours to test the radon levels again) but I'm able to hear the fan through the drain (they covered the grate with a one-way drain) at the opposite corner of the house so it's definitely getting good coverage. No issues at all, I'd recommend them to anyone with either high radon levels or those just trying to reduce the radon levels in their living space!"

Radon Detection and Reduction questions, answered by experts

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.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

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.

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.

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.
