Why Chicago prices look the way they do

The wage side of the estimate leans on insulation workers, floor, ceiling and wall, who do 80% of the hours on a typical job. Their local median is $28.29 an hour. Add the other trades involved and the blended wage index for Chicago is 1.22 (US = 1.00), which puts labor at 39% of the total.

Materials are scaled with BEA's regional price parity for goods. Chicago is at 107.3 against 100 for the US, so a materials line of $1,600 nationally becomes $1,700 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 103.6: $0 to $0.

Why two Chicago quotes can differ

  • Air sealing and fixture damming

    Sealing gaps and damming around recessed lights are part of what moves the price within a type.

  • Removing old insulation

    Old, wet or pest-damaged insulation has to come out first, at extra cost.

  • Type of insulation

    Blown-in is $0.90-$2.40 per sq ft and loose-fill is $1.00-$2.50 installed; spray foam costs more (HomeGuide).

Who does the work: Chicago trade wages

The labor line is built from BLS wage data, one trade at a time. This job draws on 2 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Chicago the blend is 1.22.

For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $28.29 an hour, which is 20% above the national $23.62. The middle half of them earn between $23.12 and $35.07 an hour. BLS counts 600 of them working in the area, 1.3 for every 10,000 jobs (US: 2.9), so the local bench is thinner than average.

For construction laborers (47-2061, weighted 20%) the local median is $29.27 an hour, which is 29% above the national $22.66. The middle half of them earn between $22.25 and $48.44 an hour. BLS counts 26,690 of them working in the area, 59.1 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.

A quick sensitivity check: moving the lead trade (insulation workers, floor, ceiling and wall) from the median to the 75th percentile wage adds about $210 to the midpoint estimate; the 25th percentile takes off about $160. That is a swing of roughly 5.6% to 7.4% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Chicago-Naperville-Elgin has 4,513,280 jobs in total (BLS, May 2025), ranking 3rd by size among the 300 metros on this site.
