Where the Champaign price comes from
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 $25.48 an hour. Add the other trades involved and the blended wage index for Champaign is 1.12 (US = 1.00), which puts labor at 40% of the total. BLS does not publish this trade for the metro, so we used the Illinois statewide median.
Materials are scaled with BEA's regional price parity for goods. Champaign is at 93.6 against 100 for the US, so a materials line of $1,600 nationally becomes $1,500 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 92.7: $0 to $0.
Data note: 80% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Champaign. The wage table below marks each row.
Why two Champaign 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: Champaign 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 Champaign the blend is 1.12.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Champaign metro, so we used the Illinois statewide median: $25.48 an hour against $23.62 for the US. The middle half of them earn between $22.33 and $34.63 an hour.
For construction laborers (47-2061, weighted 20%) the local median is $28.59 an hour, which is 26% above the national $22.66. The middle half of them earn between $21.95 and $36.74 an hour. BLS counts 570 of them working in the area, 54.0 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 $280 to the midpoint estimate; the 25th percentile takes off about $95. That is a swing of roughly 3.8% to 11.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Champaign-Urbana has 105,500 jobs in total (BLS, May 2025), ranking 196th by size among the 300 metros on this site.
