When your test shows elevated radon, mitigation is the proven fix. Most Black Hills homes use active soil depressurization: a fan and PVC system that pulls soil gas from beneath the slab or crawl liner and exhausts it outdoors.
Our approach
- Design around your foundation type and living patterns
- Seal major entry points that undermine vacuum
- Install a manometer so you can see the system working
- Plan verification testing after install
