Why two Minnesota quotes can differ
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).
Job size
Small attics start around $500 and large ones go up to $6,000 (HomeGuide).
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.
Wages behind the Minnesota number
Minnesota's labor line is priced from 2 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 1.14 times the national level.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $26.13 an hour, which is 11% above the national $23.62. The middle half of them earn between $23.05 and $35.24 an hour. BLS counts 1,090 of them working in the state, 3.7 for every 10,000 jobs (US: 2.9), so the local bench is deeper than average.
For construction laborers (47-2061, weighted 20%) the local median is $28.97 an hour, which is 28% above the national $22.66. The middle half of them earn between $23.28 and $38.32 an hour. BLS counts 28,530 of them working in the state, 96.7 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($35.24 an hour) would add about $280 to the statewide midpoint; one at the 25th percentile ($23.05) would take off about $95. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,949,820 jobs across Minnesota (May 2025), which is 1.9% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $23.05 | $26.13 | $35.24 | $23.62 | 1.11 | state |
| Construction laborers (47-2061) | 20% | $23.28 | $28.97 | $38.32 | $22.66 | 1.28 | state |

Minnesota metro-by-metro prices
1 of the 4 metros sit above the statewide midpoint of $2,650, and the top-to-bottom gap is 8%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (1,000 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Minneapolis, MN | $1,100 – $4,350 | $2,750 | +4% |
| Duluth, MN | $1,050 – $4,050 | $2,550 | −3% |
| Rochester, MN | $1,050 – $4,050 | $2,550 | −3% |
| St. Cloud, MN | $1,050 – $4,050 | $2,550 | −3% |
