"I would HIGHLY recommend Midwest Radon.  Everyone we came in contact with at this company was so professional, so polite and so friendly.  From the time I contacted Wes till the time the installers left, everyone was done with complete professionalism.  On top of that, I have a HIGH confidence that the radon issue at my home has been rectified.

"I found the experience, from the on-site quote, the explanation of services during the on-site quote, the ease of provision of all requested details before acceptance (including licensing information), the accuracy of what I was provided, contacting me to confirm go-ahead, the quality of work, the timeliness of work completion and cleanup (well inside the anticipated time window etr 3 hours, actual about 1.5 hours), the finished system solidity and finish, and the post-work explanation of what to expect, details about the system's operation, and the overnight radon monitor testing to be fantastic. I also very much liked that there was a range of payment methods, and as I opted for credit card, the payment process was simple and came to my email for me to review and pay. I had 20+ pCi/L in my basement (verified by my own testing apparatus) before work, and overnight I was down to 1 pCI/L. I felt the quote was competitive based on information sourced online prior to my consideration of the company. John Woods from Radon Mitigation Masters did an excellent job at each stage, and I would thoroughly recommend him and his company to anyone in the area needing Radon mitigation."

Radon Detection and Reduction FAQs, answered by experts

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

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.

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.

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.
