What should we do today if our office tested 5.8 pCi/L?
5.8 pCi/L is above the 4.0 pCi/L level Kentucky housing policy uses as the mitigation threshold, so mitigation planning is the typical next step. Contact a certified pro now to schedule a site visit and written quote. Ask for a confirmation test plan once the system is installed.
Can a commercial radon pro schedule work this week?
Availability depends on the contractor's schedule, so ask for the earliest date in writing. Lexington Radon Pros is free to contact and will refer you to a local pro who serves downtown Lexington. Installation of a basic system often takes 3 to 5 hours, but a large commercial building may need a full day.
How do we verify a commercial radon contractor?
Kentucky law requires any business doing radon measurement or mitigation to hold certification. Verify NRPP or NRSB certification and ask the pro for proof of licence and insurance. Also ask for references and written standard operating procedures, as Kentucky rules require.
Is commercial radon work different from residential?
Commercial buildings and large footprints with complex routing take longer to install than typical homes. Costs tend to run higher because of size and system design. Ask the pro to confirm they have experience with commercial and industrial systems before you commit.
What to do next
- Confirm your 5.8 pCi/L result with a follow-up test plan from the contractor before installation.
- Verify the pro's NRPP or NRSB certification through the Kentucky Board of Radon Safety (502-782-2782).
- Ask the pro for proof of licence, insurance, and references before signing.
- Request a written quote that itemizes the system type, routing, labour, and post-install testing.
- Call (859) 249-8571 or email [email protected] for a free quote from a Kentucky-certified (NRPP/NRSB) radon mitigation contractor.
