Where we work

We concentrate on the three Metro Detroit counties with the highest share of elevated radon results, because that is where the work genuinely is.

Mr. Radon service area, Southeast Michigan A map of Southeast Michigan counties. Oakland, Livingston and Washtenaw are shaded as the service area. Share of radon tests at or above 4.0 picocuries per litre, where Michigan EGLE publishes it: Hillsdale 52 percent, Lenawee 50 percent, Jackson 44 percent, Livingston 40 percent, Washtenaw 38 percent, Clinton 36 percent, Oakland 29 percent, Monroe 28 percent, Ingham 23 percent, Wayne 17 percent, Macomb 11 percent. Lake St. Clair, the Detroit River and Lake Erie form the eastern edge.

Oakland, Livingston and Washtenaw are the three Metro Detroit counties with the highest share of elevated radon results. Neighbouring counties shown for context.

Counties

  • Oakland County — 29% of tests at or above the action level. Royal Oak, Birmingham, Troy, Rochester Hills, Bloomfield, Farmington Hills, Novi, Waterford, Southfield, Pontiac.
  • Livingston County — 40% of tests at or above the action level, the highest in the metro area. Brighton, Howell, Hartland, Pinckney, Fowlerville.
  • Washtenaw County — 38% of tests at or above the action level. Ann Arbor, Ypsilanti, Saline, Chelsea, Dexter, Milan.

Outside those three counties

We will travel for a job that makes sense, and we will tell you honestly if you are better served by someone closer. Wayne and Macomb counties show materially lower rates of elevated results — 17% and 11% respectively — which does not mean your house is clear, but does mean testing before mitigating matters even more there.

Why we are not everywhere

Driving time is the hidden cost in this trade. A company that claims the whole state either has crews we do not, or is quoting a drive it will resent making. We would rather be genuinely available in three counties than nominally available in eighty-three.
