Common questions about radon testing and mitigation in Billings, MT and Yellowstone County.
Montana has elevated radon levels statewide. Yellowstone County tests above the EPA action level of 4 pCi/L in many homes. We recommend testing any home and mitigating at 4 pCi/L or above.
Radon mitigation in Billings typically costs $900–$1,600 for a standard sub-slab depressurization system. Cost depends on foundation type and radon concentration. Post-mitigation testing is included.
Most installations take 4–6 hours in a single day. Your home is fully usable immediately after. We retest 24–48 hours post-installation to verify results.
