Test Wexford County, MI once anyway - radon varies house to house
The predicted basement average here is 1.6 pCi/L, below the EPA's 2 pCi/L "consider fixing" threshold. That's good news for the area - but the EPA still recommends every home be tested, because foundation cracks, soil pockets and ventilation make one house very different from its neighbor. One inexpensive kit settles it.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Wexford
The typical Wexford County home is predicted below 2 pCi/L, the lowest band. That is the best case an area can show - but it describes the average house, and the ZIP-level predictions within the county still span 1.5 to 1.7 pCi/L.
The 1993 EPA zone (3) and the 2001-2021 model agree for Wexford. County figures weight each ZIP by its 2010 Census population, so they describe where people live rather than empty land.
Comparable Michigan counties: Genesee County (1.6), Antrim County (1.6), Leelanau County (1.6), Huron County (1.5). The state's highest is Branch County at 3.5 pCi/L.

Wexford County radon questions
- Is radon high in Wexford County, Michigan?
- Low. The model predicts a long-term basement average of 1.6 pCi/L in Wexford County (close to the US average of 1.8 and close to the Michigan average of 1.6). That is below the EPA's 2 pCi/L "consider fixing" threshold, though individual homes still vary. Ranked 46 of 83 Michigan counties.
- Should I test for radon in Wexford County?
- Yes, once. The EPA recommends testing every home regardless of area, and the model's ZIP-level predictions in Wexford County already range from 1.5 to 1.7 pCi/L. A short-term kit costs little and settles the question for your house.
- What does EPA Radon Zone 3 mean for Wexford County?
- Zone 3 - low potential (< 2 pCi/L). The zone map dates from 1993 and classifies whole counties. The 2001-2021 model agrees with the zone here. Neither replaces a test of your own home.
- How much does radon mitigation cost in Wexford County?
- A standard active sub-slab depressurization system typically runs $800-$2,500 installed nationally; Michigan quotes vary with foundation type (slab, crawlspace, basement), home size and local labor.
