Brandon is in Minnehaha County, where radon test results gathered by the American Lung Association average an estimated 6.5 pCi/L. Like the rest of eastern South Dakota, it falls in the EPA's Zone 1, the highest predicted radon category.
Many Brandon homes have full basements built on the region's glacial soils, and basements are where radon most often gets in: through the slab, floor drains, sump pits and the joint where the floor meets the wall.
Common situations in Brandon
- Families finishing a basement. If you're turning the basement into bedrooms or a family room, test first. It's easier to install a system before walls and ceilings go in.
- Buying or selling. A high result during inspection is common and usually fixable in a day. We can help you get a quote that fits the closing timeline.
- Sump pits. An open sump pit is a direct path for radon. Most mitigation systems include a sealed sump cover.
