About Radon in Saint-Augustin-de-Desmaures, Quebec

Last updated: March 2026

Saint-Augustin-de-Desmaures is served by C-NRPP certified radon professionals listed on RadonFinder.ca. Quebec's radon risk is concentrated in regions underlain by the Grenville geological province, including the Laurentians, Eastern Townships, the Outaouais, and parts of Mauricie, where uranium-bearing gneiss and granite produce elevated soil gas. The Montreal urban area, sitting on the St. Lawrence Lowlands, generally shows lower levels. Quebec has a high proportion of older housing stock in cities like Quebec City and Trois-Rivières, and older construction with block foundations and open sump pits tends to allow more radon entry.
