Our Radon Mitigation Process

01

Radon Testing

If you don't have recent test results, we conduct or recommend short-term (48-hour) or long-term testing before and after mitigation.

02

Diagnostic Testing

We perform suction/pressure field extension tests to determine the best system placement and pipe routing.

03

System Installation

A PVC pipe is installed through the floor slab (or membrane) and connected to a continuously running fan that draws radon from beneath the home and exhausts it above the roofline.

04

Post-Mitigation Test

A follow-up radon test confirms the system is achieving adequate reduction — typically to below 2.0 pCi/L.

Radon Mitigation FAQ for Sioux Falls Homeowners

How often should Sioux Falls homeowners get radon mitigation?
Given Sioux Falls's extreme continental climate with blizzard risk november through april, most homeowners benefit from radon mitigation at least once a year. Blizzard snow removal and roof load management (November–April) often makes spring or fall the optimal time to schedule service.
What home types in Sioux Falls most need radon mitigation?
Ranch and two-story homes throughout Minnehaha County and New construction in northwest and southeast Sioux Falls growth corridors are the most common home types in Sioux Falls and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What radon level requires mitigation?
The EPA recommends mitigation at levels of 4 pCi/L or higher. Consider mitigation at 2–4 pCi/L as there is no truly safe level of radon exposure.
How much does radon mitigation cost?
Most residential mitigation systems cost $800–$2,500 installed, depending on house construction and foundation type. This one-time cost provides lifetime protection.
How does a radon mitigation system work?
Sub-slab depressurization (SSD) is the most common method — a fan creates negative pressure beneath the slab that draws radon away from the home before it can enter, exhausting it harmlessly above the roofline.
Will a mitigation system affect my heating and cooling bills?
Sub-slab depressurization removes a small amount of air from beneath the slab, not from inside the home. The impact on energy costs is negligible.
