"Project: Radon Mitigation I highly recommend Advanced Radon. 1. Advanced Radonâ s mitigation system decreased the radon in my house from 40 pCi/L to at or below 2 pCi/L within two days. 2. Advanced Radon guaranteed reduction of radon under 4 pCi/L (the industry standard). 3. Advanced Radon offered an effective product at a reasonable price. 3. The technicians showed up on time and worked diligently until the job was finished. We had agreed ahead of time on where the piping would be located so as to maintain aesthetics, and I am pleased with the results. 4. Advanced Radon offers radon testing before and after the mitigation system was installed to ensure success. 5. I was extremely impressed with the education level of the technician. He answered all of my questions throughly. He even had pictures and diagrams available to help explain the answers. As an engineer, he had patented several pieces of equipment to ensure a safe and effective installation of the mitigation system. Overall I was very impressed with Advanced Radon. I would highly recommend them to anyone struggling with high radon readings in their home. I feel confident that if I ever had a problem with the system, Advanced Radon would address it."

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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

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