"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."

"I used Vespene Radon Testing earlier this year and was very satisfied with the experience from start to finish. They were punctual, professional, and very knowledgeable on all things radon testing. Results came back quickly, which mattered to me as a parent of a young child. Having reliable data in hand promptly gave me confidence that our home was safe. I would definitely use them again for any of my radon testing needs ."

"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

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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.

Yes, many systems include warranties for performance. Confirm terms with your installer.

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.

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.
