"Radon Abatement services is a reliable dependable superb company. I have had an excellent experience from start to finish. Scheduling was easy and expeditious, service was professionally and very well done. Most importantly, Radon is gone with its in-house level reduced to almost its outside level. John Swett was very helpful and kindly answered all my emails and quickly addressed every concern I had. This project could not have been done better."

Customers say: Quick response

"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."

"We needed the fan replaced on our radon mitigation system. Atlantic Radon responded quickly, confirmed appointment time, called to see if he could arrive early (which he did), had the appropriate replacement for our 32 year old unit, and completed the job in a short time. The "tech" was the owner - pleasant, knowledgeable, easy to work with. Recommend Atlantic highly."

"The work has not yet been done - scheduled for two days from now. Very pleased with the estimate and service to date. The work has now been completed. An excellent job configuring the stacks to be as unobtrusive as possible, sealing cracks and floor drain, and installing a radon flow alarm. An independent radon test has been scheduled now that the work has been finished. Excellent company. Highly recommended."

Radon Detection and Reduction questions, answered by experts

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

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).
