Why North Carolina runs below the US average

Radon mitigation pricing in North Carolina reflects three regional factors: licensed HVAC / specialty trade wages (BLS), EPA Zone density (Zone-1 states have mature mitigator markets and competitive pricing), and state-specific permitting / disclosure requirements. The 0.98× factor is calibrated from 2025 AARST + HomeAdvisor regional rate data.

Local note · North Carolina: Mostly Zone 2-3 with Zone 1 pockets in the Mountains. Charlotte and Asheville have strongest mitigator density.
