"They installed a Radon Mitigation system in a house I was selling. They had the best price, the experience I wanted, and were able to install a few days after I called. Technician was very nice and efficient in getting it installed. Good warranty too. I had my system installed in an encapsulated crawl space."

"Our radon specialist, Tim Milledge, was terrific. Communication was excellent, he arrived on time, was professional, courteous and experienced. He was able to run the pipe line and place the other equipment in a way to be unobtrusive and did nothing to detract from the aesthetics of our property. He explained post procedures and cleaned up after himself, unusual these days with service providers, and completed the installation quickly and efficiently. We would highly recommend SWAT and, in particular Tim."

Radon Detection and Reduction questions, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

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.

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.
