"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

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.

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

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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