Bozeman Radon & Mold provides professional, NRPP-accredited radon testing in Bozeman and throughout Gallatin County, helping homeowners better understand their indoor air quality and potential radon exposure.
Our testing is performed by a NRPP-certified Radon Measurement Professional (License #115697-RMP) and follows ANSI-AARST and NRPP testing protocols to ensure accurate, reliable results. We deploy calibrated Continuous Radon Monitors (CRM) in the lowest livable level of the home under closed-building conditions.
Radon test results are typically available within 24–96 hours, depending on test type and site conditions. We offer free radon testing, clear reporting, and guidance on next steps if elevated levels are identified, including when radon mitigation may be recommended.
