"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 FAQs, answered by experts

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.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.
