"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."

"I'm completely satisfied with the work that John's team did. They were extremely professional and knowledgeable. The workmanship is superb. Best of all, the system works as promised and reduced the radon concentration based on subsequent tests. I could not recommend them more highly."

"They were polite and quick to get the work done. The first installation was not sufficient to reduce the radon levels but they came out a second time, free of charge, to make the necessary changes. The final result was more than satisfactory."

"JT of Dragon Ridge performed a Home Inspection and Radon Testing of a SFH in Fairfax, VA. JT arrived before I did, and was already examining the exterior of the property. While we waiting for my realtor to arrive, he grabbed a ladder and did a complete inspection of the roof (not all inspectors do this). Once we got inside, he explained the processes and we began. I shadowed him throughout the whole processes, and it was a wonderful experience. He was very thorough and knowledgeable, and was always willing to provide complete and educational answers about both the good and the bad he found. We got the report later that evening, and it was well written, with plenty of pictures of any deficiencies. He also performed a Radon test, and reported the results a few days later. I spoke to him over the phone about the findings, and he was able to discuss in detail the methodology he used, and the meanings of the testing numbers. Overall, I would highly recommend JT and Dragon Ridge."

Radon Detection and Reduction FAQs, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.
