Abstract: A kit for reducing the level of radon in a dwelling. Containing a rain-proof exhaust vent hood housing an axial fan, and a suction pipe attached to a length of flex-duct. The kit can be easily installed by most homeowners. The installer simply cuts a hole in the band-board atop the foundation wall of the dwelling, inserts the assembled vent hood and suction pipe in the band-board opening, attaches the proximal end of a length of flex-duct and positions the distal end of the flex-duct into a de-pressurization point in the dwelling. An existing sump pump well or drain tile field can serve as a de-pressurization point.
