Serving Eastern South Dakota
Eastern South Dakota sits on glacial till and Pierre Shale bedrock — geology that naturally concentrates uranium decay products and produces radon gas. Combined with the cold winters that keep homes sealed for months, radon accumulates rapidly in basements and lower levels throughout the region.

A certified testing device is placed in the lowest livable area of your home for 48–96 hours. It's non-invasive, requires no equipment setup by you, and produces zero disruption to your daily routine. Once retrieved, your written report is ready within 24 hours.

Common Questions
Frequently Asked Questions About Radon
-
Radon is a colorless, odorless radioactive gas that seeps up naturally from soil and rock. It is the leading cause of lung cancer among non-smokers and the second leading cause overall in the US, responsible for approximately 21,000 deaths each year according to the EPA. The EPA recommends taking action when indoor levels reach or exceed 4.0 pCi/L.
-
Yes. South Dakota consistently ranks among the highest states for radon levels. The EPA classifies the majority of South Dakota — including Minnehaha and Lincoln Counties near Sioux Falls — as Zone 1, the highest radon potential designation. The state's glacial till soils and Pierre Shale bedrock naturally concentrate uranium decay products that produce radon gas.
-
Radon seeps into homes through cracks and gaps in the foundation, floor-wall joints, openings around service pipes, and construction joints. Because South Dakota's cold winters keep homes tightly sealed for months at a time, radon can accumulate to elevated levels — especially in basements and lower-level living areas.
-
Professional short-term radon tests typically start around $150 for a standard home. Real estate tests include expedited reporting to fit inspection timelines. Contact us for an exact quote based on your property type and location — all estimates are free and no-obligation.
-
If your test results come back at or above 4.0 pCi/L, radon mitigation is recommended. The most effective solution is a sub-slab depressurization (SSD) system — a pipe and fan that draws radon from beneath your foundation and vents it harmlessly outside before it can enter your living space. We'll walk you through all options, costs, and timelines.
-
Most radon mitigation installations are completed in a single day, typically 4–6 hours. After installation, a follow-up test confirms that radon levels have dropped below the EPA action level. A written report documenting the system and post-mitigation results is included.
-
Yes. Sub-slab depressurization systems reduce indoor radon levels by up to 99% in most cases. Mitigation is a proven, well-established technology with decades of EPA research behind it. Results are always verified with a post-mitigation test, which is included with our mitigation service.
-
Absolutely — especially in South Dakota. Radon testing is one of the most important and frequently overlooked home inspections. We offer fast-turnaround real estate tests designed to fit within standard inspection contingency windows, so you get results before you're committed to the purchase.
