Radon in Western North Carolina: What Homeowners Should Know

The useful question is the level in your home

Radon is a naturally occurring radioactive gas that can enter buildings from the ground. You cannot judge an indoor measurement from the view, the age of the house or a nearby property’s result. The NC Radon Program recommends testing every home, including homes on crawlspaces and slabs.

For a western North Carolina buyer, this makes radon a separate planning question even when a property looks well maintained. A standard visual home inspection does not measure it.

Plan testing around actual access

Tell Grounded the property address and your deadline early. Monitor placement and collection require access, and a typical Grounded short-term appointment includes a 48-hour measurement period. The testing instructions matter as much as scheduling the visit.

Ask who will tell occupants and contractors about the closed-building conditions. Do not move or disturb a monitor. If access, weather or building use interferes, tell the testing professional so the effect on the test can be considered.

Use the result to choose follow-up

EPA recommends reducing radon at 4 pCi/L or more and considering reduction between 2 and 4 pCi/L. These are action guidelines, not a declaration that lower exposure carries no risk. A qualified mitigation contractor handles reduction work.

Keep the complete test report, including where and when testing occurred. A short-term result describes that testing period; it should not be treated as a guarantee about every season or future building condition.

Questions worth asking

Was the area tested one that will be occupied? Have renovations or living patterns changed since an earlier test? Is there a mitigation system, and is there a recent measurement of its performance? Share previous reports when arranging a new test. Grounded can discuss scheduling and reported measurements without promising a particular result.
