Radon mitigation cost in St. Louis can vary quite a bit depending on your home's foundation type and the system needed. Most homeowners here pay between $800 and $2,500 for a standard active soil depressurization system, though crawlspaces or slab foundations may require more work and higher expense. It's a worthwhile investment given the region's elevated radon risk.
