"Bob and his crew did a great job. From dealing with the office staff from the first call all the way until job completion I was impressed with the service. Not only that he had the best quoted price as well and while this may not seem like a big deal there were a few factors that made this impressive. First he was coming from further away than any other company, a lot further, over an hour away. Next he quoted the job site unseen and found that a portion of the work he quoted was already done when he arrived onsite so after the lab test came back showing everything within acceptable ranges he surprised me with a refund for that portion of the job that he didn't have to perform."

"This team was professional, as well as friendly and knowledgeableâ ¦gave us up front scenariosâ ¦ we didnâ t have to pay them before OR after the job was done (once the testing is done and we are SATISFIED, we are to pay the bill â ¦which was a little higher than the first company we contacted but the first company wanted payment up front and said nothing about OUR satisfaction). We were appreciative of the explanation of what was done and what WE needed to do to make sure the system was working properly. We got clear instructions on testing after installation. So far, so good! We are pleased."

Radon Detection and Reduction FAQs, answered by experts

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.

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.

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

Yes, many systems include warranties for performance. Confirm terms with your installer.

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.
