Planning range: Many single-family ASD systems nationally cluster roughly between $800 and $2,500, with complex homes higher. Black Hills quotes vary with foundation type, pipe run length, crawl encapsulation needs, and whether interior or exterior fan placement is required.1 Call (605) 600-6282 for a property-specific discussion.
What drives price
- Foundation type (full basement, crawl, combination)
- Number of suction points
- Interior vs exterior pipe routing and homeowner cosmetic preferences
- Sumps, drains, and sealing scope
- Fan size and noise/esthetics constraints
- Post-mitigation testing included or separate
What a complete job should include
Suction point(s), piping, fan, exterior exhaust, system labeling, manometer, basic sealing of major entry points, homeowner orientation, and a plan for verification testing. Ask whether electrical work is included.
Cost vs risk
Compared with long-term health risk and with other home systems, mitigation is usually one of the higher-ROI environmental fixes—especially before finishing lower levels.
