A radon reduction system draws air from the soil around a home's foundation and vents it safely above the roofline, preventing radon gas from seeping into living spaces. It's a straightforward solution that runs continuously with a quiet fan, often installed in a basement or crawl space. Testing your home is the first step, and if levels are high, a mitigation expert can design a system tailored to your house's foundation type and soil conditions.
