"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

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.
