What insulation workers, floor, ceiling and wall and the other trades earn in Colorado
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 2 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.03 for Colorado.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $24.42 an hour, 3% above the US median of $23.62. The middle half of them earn between $22.71 and $29.87 an hour. About 1,210 work in the state. That is 4.2 per 10,000 jobs, compared with 2.9 nationally, which suggests plenty of local crews to bid.
Construction laborers (47-2061), 20% of the weighting: a median of $23.03 an hour, in line with the US median of $22.66. The middle half of them earn between $20.53 and $27.25 an hour. About 18,680 work in the state. That is 65.0 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($29.87 an hour) would add about $170 to the statewide midpoint; one at the 25th percentile ($22.71) would take off about $50. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,873,900 jobs across Colorado (May 2025), which is 1.8% of US employment.
