"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'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."

"Ryan was right on time both for the dropoff and pickup for doing a Radon test of my basement. He's a great communicator and is very personable! He was able to give me a fair assessment of the test results this time, how they related to the results I had gotten at closing of my home, giving me all the info necessary to feel comfortable on my plan of action. I would highly recommend him!"

Radon Detection and Reduction questions, answered by experts

Installation typically takes 1-2 days, depending on the system and property layout.

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.
