Our Mitigation Process

Three steps, one day on site for most homes.

  • 01

    Foundation Drilling

    We drill a precise suction point through your concrete slab to access the soil gas beneath your home.

  • 02

    Professional Piping

    We route Schedule 40 PVC piping from the suction point to the exterior, ensuring the most aesthetically pleasing path.

  • 03

    Fan Installation

    We mount a premium Festa AMG fan to actively draw radon gas out from under your foundation and vent it safely above your roofline.

How Active Soil Depressurization Works

Radon enters your home because the air pressure inside is usually lower than the pressure in the soil beneath your foundation. This creates a vacuum effect, drawing the radioactive gas up through cracks and pores in the concrete.

We fix this using a method called Active Soil Depressurization (ASD). By installing a pipe into the sub-slab gravel and connecting it to a specialized fan, we reverse the pressure difference. The fan safely pulls the radon gas out from under your home and vents it above the roofline before it can ever enter your living space.

The fan runs 24/7 for years, so we only install premium Festa AMG fans: whisper-quiet, 7-year warranty, efficient EC motor, and weather-sealed for Iowa winters.
