Installing a radon fan involves running a vent pipe from the sump pit in your basement or crawlspace up through the roof or an exterior wall, then mounting the fan securely in the attic or outside. Proper sealing and correct fan sizing are critical to ensure the system continuously pulls radon gas from beneath the foundation and vents it safely above the roofline, reducing your indoor radon levels to safe limits.
