Radon Mitigation in
Sioux Falls, SD
If your Sioux Falls home tested above 4.0 pCi/L, sub-slab depressurization (SSD) is the most effective path to safer indoor air. The glacial till foundations common across Minnehaha and Lincoln County respond well to SSD — most systems are installed in one day and confirmed effective through a post-installation test.

How Radon Mitigation Works
A proven four-step process from assessment to confirmed results.
Assessment
We evaluate your Sioux Falls home's foundation type, test results, and construction to determine the right mitigation approach.
System Design
We design a sub-slab depressurization system with optimal suction point placement, pipe routing, and fan selection for your home.
Installation
Most Sioux Falls homes are installed in a single day. We drill a suction point, route the pipe, and install the fan with minimal disruption.
Post-Install Test
A follow-up radon test confirms the system is working. We revisit if levels need further reduction until you have a result you're satisfied with.
Sioux Falls Mitigation Context
Mitigation for Sioux Falls Zone 1 Homes
Sub-slab depressurization works by creating a low-pressure zone beneath your foundation slab. A fan continuously draws radon-laden soil gas from below the foundation and exhausts it above the roofline, before it ever enters your living space. For the glacial till and Pierre Shale geology beneath Sioux Falls, SSD is highly effective because the soil is permeable enough to allow good suction distribution with one or two suction points.
Sioux Falls home construction varies significantly — from older homes with poured concrete basements near Falls Park and Downtown, to newer slab-on-grade builds in Harrisburg and Tea. Foundation type affects pipe routing and suction point placement, but all common foundation types in the area can be effectively mitigated. Crawl spaces require a different approach — typically a sealed membrane with passive or active ventilation — but the goal is the same.
After installation, radon levels in most Sioux Falls-area homes drop to below 2.0 pCi/L, well under the EPA's 4.0 pCi/L action level. The system operates continuously at very low power consumption — comparable to a light bulb — and requires only periodic monitoring to confirm it's working.

Radon Mitigation in Sioux Falls — FAQ
Mitigation costs vary based on foundation type, home size, and system complexity. Single suction-point installations in Sioux Falls-area homes with standard basement construction are typically straightforward. More complex homes with multiple foundation types or unusual construction may require additional suction points. We provide a specific quote after assessing your home — no hidden fees or surprises.
A typical SSD system includes a PVC pipe routed from a suction point beneath your floor slab, through the home or along the exterior wall, to above the roofline. A radon fan is installed in the pipe — usually in the attic or on the exterior. Exterior routing is common in Sioux Falls homes and keeps the system largely out of sight. The fan is relatively quiet and energy-efficient. We discuss routing options with you before installation.
Most Sioux Falls-area mitigation installations are completed in a single day — typically 3–6 hours depending on home complexity and routing. You'll need to be present (or have someone present) for access. The home is usable immediately after installation. The post-installation confirmation test is typically scheduled a few days later.
Properly installed SSD systems typically reduce radon levels by 50–99%. Most Zone 1 Sioux Falls homes reach levels below 2.0 pCi/L — well under the EPA's 4.0 pCi/L action level. The post-installation test measures the actual result. If levels need further reduction, we adjust the system (typically increasing fan capacity or adding suction points) until the result is satisfactory.
