"I employed the services of Radon Mitigation Master to run a radon test, install a radon mitigation system, and then retest. From start to finish, John and Ed were punctual, always communicated and kept the line of communication open for any questions I had. They conducted the install very quietly, clean, and efficiently. They then retested, and the system was able to reduce the radon by 90% plus. I would recommend RMM to any acquaintance, friend, or family member. Thank you John and Ed!"

"The Advanta team was superb in every way. During the proposal stage they documented the work to be done with specificity and answered each question we asked. During the project, the techs were unobtrusive, professional and responsive to our needs. The work was completed on the agreed upon schedule and our home tested clean to earn a clearance letter from our testing firm. Our family had dreaded the cost and disruption that we imagined the remediation would cause but Advanta performed its tasks in a manner which proved each of our concerns were unfounded. We recommend Advanta without reservation for mold remediation."

"I would definitely recommend this company to anyone!!! I hired them and the job was done nicely, Dan O'Brien was the technician who took care of the project and he did an excellent job, he answered all of my questions and explained to me everything related to Radon gas. When he finished setting everything up and the job was completed all the working area looked super clean and the installation looks just like it is part of the house and that has been there forever. This is what I call a Perfect and Complete execution of a Radon gas mitigation project."

"We had a last minute reschedule do to tenant issues and he worked with us to get the inspection done the next day. He was 15 minutes early because he wanted to talk to the maintenance people before they went home for the day. He seems to be an experienced home inspector with a stellar work ethic. 10/10 would reccomend."

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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.

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

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

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