Radon Mitigation in Sioux Falls, SD

If your home tested at or above the EPA's action level of 4.0 pCi/L, radon mitigation is how you bring it back down – permanently. We design and install certified radon reduction systems for homes and businesses across Sioux Falls and the surrounding metro.

What radon mitigation actually does

The most proven, effective method is sub-slab depressurization. We install a sealed vent pipe and an in-line fan that create a slight vacuum beneath your foundation, capturing radon gas before it enters your living space and venting it safely above the roofline. A well-designed system reduces radon by up to ~99% and keeps it low for the life of the home.

Our mitigation systems

• Sub-slab depressurization – the standard for basements and slab-on-grade homes
• Sump-pit and drain-tile systems – tie into existing drainage where present
• Crawl-space depressurization – sealed membrane systems for crawl-space homes
• Sealing – closing foundation cracks and openings that let radon in
