Certified Radon Mitigators
in Reno, Nevada

Reno and Washoe County sit in the eastern Sierra Nevada foothills and Great Basin at around 4,400 feet elevation, where granite and metamorphic bedrock from the Sierra combined with Basin and Range volcanic geology produce elevated radon in many parts of the metro. Nevada's statewide average is around 2.5 pCi/L, but Reno-area homes in the foothills neighborhoods — Caughlin Ranch, St. James Village, and the area around Slide Mountain — test above the action level with more frequency than the state average implies. Reno's rapid growth and the prevalence of slab-on-grade construction in newer developments don't eliminate radon risk. Nevada has a limited certified contractor market; NRPP or NRSB credential verification is essential.
