Wages behind the Louisiana number
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 0.93 for Louisiana.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $22.76 an hour, 4% below the US median of $23.62. The middle half of them earn between $21.48 and $28.29 an hour. About 1,610 work in the state. That is 8.3 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 $18.38 an hour, 19% below the US median of $22.66. The middle half of them earn between $16.59 and $22.74 an hour. About 22,100 work in the state. That is 114.2 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($28.29 an hour) would add about $170 to the statewide midpoint; one at the 25th percentile ($21.48) would take off about $40. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 1,934,900 jobs across Louisiana (May 2025), which is 1.2% of US employment.
