Questions about Massachusetts insulator pay
What is the insulator prevailing wage in Middlesex County?
$92.08 an hour: a $55.45 base wage plus $36.63 in fringe benefits, under wage determination MA20260001, modification 1. Overtime and every insulator classification in Middlesex County.

Do apprentice insulators get this rate?
Davis-Bacon determinations list journeyworker rates. Apprentices in a program registered with DOL or a recognized state agency can be paid the program's percentage of the rate, within its ratio; anyone else gets the full rate (29 CFR 5.5(a)(4)).
Why do some counties have the same insulator rate?
DOL often publishes the same insulator rates for several counties. Across Massachusetts, the 14 counties with an insulator rate fall into 7 distinct sets of rates, and 3 of those sets are shared by more than one county; the largest covers 4 counties (the Essex County group).
