The EPA recommends taking action to reduce radon when levels reach 4 pCi/L or higher. Rn86 Solutions uses NRPP-certified Continuous Radon Monitors to give you an accurate 48-hour measurement of your home's radon levels.

Question 2

How long does radon mitigation take in East Tennessee?

Accepted Answer

Most residential radon mitigation installations in East Tennessee are completed in a single day. Rn86 Solutions begins every job with PFE (Pressure Field Extension) diagnostic testing, installs the Active Soil Depressurization system using Schedule 40 PVC, and performs post-mitigation verification - all by a certified professional on site from start to finish.

Question 3

Is radon a problem in Knoxville and Oak Ridge, Tennessee?

Accepted Answer

Yes. Anderson County (Oak Ridge) and Knox County (Knoxville) are both EPA Zone 1 counties, meaning they have the highest predicted average indoor radon levels. The region's shale-rich, uranium-bearing geology makes radon testing essential for every home.

Question 6

How do I choose a radon mitigation company?

Accepted Answer

Key questions to ask: Are they NRPP or NRSB certified? Do they perform PFE testing before installation? Do they use Schedule 40 PVC pipe? Is an audible alarm included? Do they conduct post-mitigation testing with a calibrated CRM? Rn86 Solutions answers yes to all of these - and publishes a full guide on what to ask any radon company before hiring them.

Question 7

Does radon testing need to be done before selling a home in Tennessee?

Accepted Answer

Radon testing is not legally required to sell a home in Tennessee, but it is commonly requested by buyers and their real estate agents, particularly in high-risk Zone 1 counties like Knox, Anderson, and Blount. Many buyers and lenders also require radon mitigation if levels exceed 4 pCi/L before closing. Rn86 Solutions works closely with real estate agents throughout the Knoxville and Oak Ridge area.
