Best Radon Testing & Mitigation in Gatineau

About Radon in Gatineau, Quebec

Last updated: March 2026

Gatineau 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.

Typical Mitigation Cost in Quebec

$2,200–$3,600

Montreal-area labour rates apply in the urban corridor; rural and Laurentian regions may see higher costs due to contractor travel.

  • •Foundation type: block, poured concrete, or stone foundations in older Quebec homes
