Radon Mitigation in Brookings, SD
Call (605) 210-7667 Brookings County, 58 miles from Sioux Falls, population about 23,900.
The largest town in the regional service area, anchored by SDSU and a real manufacturing base.
Why radon is a problem in Brookings
Brookings sits on the flat Coteau slope on deep glacial till, well north of the quartzite outcrops. Flat ground, deep basements and long heating seasons combine into a strong winter stack effect.
What Brookings housing is built like
A wide spread: pre-war housing near campus, dense 1960s and 1970s development, steady new construction on the south and west edges, plus a large rental market serving the university. Commercial and institutional buildings are a meaningful share of the radon work here.
Brookings has enough institutional and multifamily square footage that commercial-protocol measurement is a regular job here, not an occasional one.
Who calls us from Brookings
Brookings generates the widest range of work in the regional service area: single-family transactions, university-adjacent rental property, new construction on the south and west edges, and genuine commercial and institutional measurement. The season matters here more than most places, since a January test on the Coteau reads meaningfully higher than a July one in the same house.

What is particular about Brookings
Season matters more in Brookings than anywhere else we work. Deep basements on the Coteau plus a five-month heating season create a sustained pressure difference that pulls hard on the soil, and a house reading 2.8 in July can read 5.5 in January. Neither figure is wrong; they answer different questions. For a transaction the contract dictates the timing. For an owner deciding whether to spend money, a long-term device spanning the heating season is the honest number and we will say so even when it delays work.
Common questions from Brookings
Should I test in summer or winter?
A summer reading is the low end of your annual range here. If it came back near 4 rather than near 1, retest through the heating season before deciding.
Do you work on rental properties near SDSU?
Regularly, and multiple properties scheduled in the same week share the trip, which matters when the drive is 58 miles each way.
Scheduling and travel
Fifty-eight miles north to I-29 exit 132, scheduled in blocks. Two or three jobs in the same week and the trip charge disappears, so it is worth asking who else on your street has been meaning to deal with this.
