Insulator (Heat & Frost / Asbestos Worker) prevailing wage, Houghton County group, Michigan (10 counties)

LEO sets the same insulator rates, row for row, in 10 counties: Alger, Baraga, Delta, Dickinson, Houghton, Iron, Keweenaw, Marquette, Menominee and Schoolcraft. Every figure on this page applies in each of them.

$75.97an hour, fringe benefits included · Heating and Frost insulators

One rate, fringe benefits included (LEO prints no split)

On Michigan public works in each of these 10 counties, an insulator working as heating and frost insulators must be paid at least $75.97 an hour. LEO prints one rate with fringe benefits included, so there is no separate base wage.

LEO county rates, November 2025 edition, effective October 31, 2025. The contracting agent gets LEO's rates before advertising and puts them in the specifications; if the contract isn't awarded or started within 90 days of LEO's determination, LEO must redetermine them (MCL 408.1103). Checked against michigan.gov on October 25, 2026.

One rate, fringe benefits included: $75.97

LEO publishes a single hourly figure that already includes fringe benefits. A contractor can pay it all as wages, or pay part as contributions to bona fide benefit plans for the worker, as long as the two add up to at least $75.97. LEO doesn't publish a base and fringe split, so this page doesn't invent one.

LEO's data note: LEO prints package rates only (wage + fringe at straight time, 1.5x, 2x)

Davis-Bacon insulator rates in these counties

The counties share LEO's rates, but not always the same federal wage determination. Contracts that already require Davis-Bacon rates are exempt from Michigan's Act, so a Davis-Bacon job uses the federal rate (MCL 408.1102(1)).
