Tipper's take on radon in Candler
Candler sits in Buncombe County, which the EPA classifies as Zone 1, the highest risk category. That means the agency's geological and indoor measurement data predicts average indoor radon levels above 4 pCi/L across the county. CDC data from Buncombe County puts the average measured radon level at 3.6 pCi/L.
Zone 1 doesn't mean every home in Candler is over the limit. Radon varies house to house depending on foundation type, soil composition, and how the home is sealed. The county-level signal is strong enough that Tipper considers testing essential here.
A basic test kit costs about $15, takes 48 hours, and settles the question. If your home is below 4 pCi/L, you're good. If it's above, a mitigation system typically costs $800–$2,000 in North Carolina and brings levels down reliably.
