South Dakota DANR publishes these figures for an active soil depressurization system, the method the EPA generally recommends (SD DANR):
Average installation cost
Average operating cost in South Dakota
Expected fan life span
Fan replacement cost
These are state-level averages from DANR, not quotes from Rapid City contractors. Your price can be higher or lower.
DANR describes active soil depressurization as PVC pipe connected to the soil through a hole in the slab, a sump lid or beneath a plastic sheet in a crawl space, with a quiet, continuously running fan that vents radon outside. DANR says even very high levels can be reduced to acceptable levels.
Foundation type, home size and layout, how many separate slabs or crawl spaces there are, and where the pipe and fan can be routed. Ask for a written quote, confirm the installer's certification (DANR links to NRPP and NRSB listings), and plan a follow-up test after installation. Use the form above to get matched with a local professional.
South Dakota DANR lists an average installation cost of $1,200 for an active soil depressurization system, an average operating cost of about $3 per month in South Dakota, an expected fan life of 11 years, and a fan replacement cost of $145 to $300. Your actual price depends on your home.
