Salt Lake, Utah, Davis, and Weber counties.
We cover the Wasatch Front: Salt Lake County, Utah County, Davis County and Weber County, from the north end of Ogden down through Provo and Orem, across the Salt Lake valley, and out through the towns along the benches and the west side. If your house sits in that stretch, we can point you to contractors who test, contractors who install mitigation systems, and contractors who service systems that are already in place.
We do not publish claims about which areas read high and which read low, because that framing misleads people. Radon originates in the soil under a specific lot and enters through the specific openings in a specific foundation, so identical houses on the same street can measure differently. Utah's Department of Environmental Quality publishes maps and state guidance that are worth reading for context, but the only reading that describes your address is a test at your address.

The pages above are the cities we write about in detail, but coverage runs the length of the Wasatch Front. If your town is not listed, it almost certainly still falls inside the area — call 801-644-9000 and ask.
Coverage spans four counties. Salt Lake County runs from the north end of the valley down through Draper and Herriman. Utah County covers Lehi and American Fork south through Orem and Provo. Davis County takes in Bountiful, Farmington, Kaysville, and Layton along the north corridor, and Weber County covers Ogden and the towns around it.
Each city page exists because the housing stock and the conditions genuinely differ from one end of that stretch to the other. A home built in the 1950s near downtown Salt Lake and one built in the last decade in a Utah County subdivision present different problems, and the pages are written to reflect that rather than to repeat the same page with a place name swapped in.
Test first, then decide. There is no fee to be matched.
