Radon Mitigation in Brandon, SD

Call (605) 210-7667 Minnehaha County, 9 miles from Sioux Falls, population about 10,900.

Fast-grown commuter town east of Sioux Falls, built almost entirely on poured-wall basements with sump crocks.

Why radon is a problem in Brandon

Brandon sits on glacial till above the Sioux Quartzite shelf, with Split Rock Creek having cut down through it right in the middle of town. Where the till is thin over fractured quartzite, soil gas has a short trip to the underside of a slab.

What Brandon housing is built like

The overwhelming majority of Brandon housing went up between 1995 and 2015, which means poured concrete walls, a full basement, drain tile to a sump crock and a slab that was almost never sealed at the cold joint. That is the single most mitigable foundation type there is.

Because so much of the town shares one construction era, the systems look alike and the pricing is predictable. Brandon is where a quote should not surprise anybody.

Who calls us from Brandon

Most Brandon calls come from one of three places: a purchase agreement with an inspection result attached, a homeowner who finally read the manometer on a system installed twenty years ago, or somebody whose neighbour just got a number and mentioned it over the fence. Brandon talks, which is why this town tests more than its size would predict.

What is particular about Brandon

What makes Brandon unusual in this market is how consistent the housing is. When a town gets built over twenty years to broadly one pattern, the systems look alike, the pricing is predictable, and a quote given over the phone tends to hold. The exception is the older stock nearer Split Rock Creek, where the till thins over the quartzite shelf and both the readings and the foundations get less uniform. That is the part of town where we would rather look before pricing.
