"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."

"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."

"I purchased a radon kit to asses the need for radon mitigation but I was educated by the business owner himself who was incredibly knowleadeable and helpful. If we do have radon over the next 6 months after seeing what the averages are from winter to summer, this is the company we will gladly hire!"

"During the initial contact, I was impressed with the explanation of the testing process provided by the individual who answered my call. I was equally impressed by Mr. Robinson's step-by-step explanation while he set up the equipment to perform the test. He explained his licensing and the accuracy of the test that he was conducting. He was professional, efficient and possesses a great deal of expertise in his chosen field. He informed me when to expect the results of the testing and followed up with a phone call explaining the report in minute detail. Looking forward to working with Mr. Robinson for the next step in this process. Thanks again. -- Roger K"

Radon Detection and Reduction FAQs, answered by experts

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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

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

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

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.
