"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."

"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!!"

"Mark did great work and made the radon abatement system blend well with the house. The office response time was slower than I would have liked, but the price and quality of work was worth the wait. All of the people I interfaced with were extremely helpful and nice. I would highly recommend this company."

"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 questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
