What should we do today and this week?
Keep the elevated test results documented and share them with HR and building management. Under Kentucky guidance, levels at or above 4.0 pCi/L require a mitigation plan that records the initial test level and considers occupant health risk. Request a referral now so a certified pro can assess the building promptly.
What should we check when hiring or switching contractors?
Verify certification through Kentucky's state radon office, the Kentucky Radon Program, within the Department of Public Health. Kentucky law prohibits any business from conducting radon measurement or mitigation without the appropriate certification. Ask the pro for proof of licence and insurance and for a written quote that names the system design.
Does commercial work need special certification?
Yes. Kentucky law defines a commercial building as any building other than a residential building, including buildings for public purposes, and defines mitigation to apply to buildings generally. Kentucky requires certified radon professionals for measurement and mitigation statewide, so a general handyman is not appropriate for office-park work.
Is testing required before reoccupancy?
Kentucky Housing Corporation policy requires radon testing after construction but before occupancy for new builds. Its policy also covers existing commercial and mixed-use buildings, which confirms that commercial mitigation is a recognized service category. Use the same certified-professional standard for follow-up testing after mitigation.
