Attic insulation cost by metro in Maine
0 of the 2 metros sit above the statewide midpoint of $2,450, and the top-to-bottom gap is 1%. 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 |
|---|---|---|---|
| Portland, ME | $980 – $3,900 | $2,450 | level |
| Bangor, ME | $970 – $3,900 | $2,400 | level |
Why two Maine 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.
Other Maine jobs that often go with attic insulation
Each project weights the trades differently, so Maine's wage level does not push every price by the same amount. Compared with the US midpoint, vinyl siding is −1% and roof replacement −6%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Roof replacement | 2,000 sq ft of roof | $5,700 – $11,800 | −6% |
| Metal roof | 2,000 sq ft of roof | $9,550 – $31,000 | −5% |
| Vinyl siding | 2,100 sq ft of wall | $8,350 – $25,000 | −1% |
| Window replacement | 10 windows | $4,300 – $14,400 | −4% |
| Gutters | 160 linear ft | $1,250 – $4,100 | −3% |
Wages behind the Maine number
Maine'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 0.97 times the national level.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $22.97 an hour, which is in line with the national $23.62. The middle half of them earn between $19.38 and $27.65 an hour. BLS counts 440 of them working in the state, 6.9 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 $22.32 an hour, which is in line with the national $22.66. The middle half of them earn between $19.51 and $25.51 an hour. BLS counts 3,960 of them working in the state, 61.8 for every 10,000 jobs (US: 70.5), so the local bench is about average.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($27.65 an hour) would add about $140 to the statewide midpoint; one at the 25th percentile ($19.38) would take off about $110. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 640,610 jobs across Maine (May 2025), which is 0.4% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $19.38 | $22.97 | $27.65 | $23.62 | 0.97 | state |
| Construction laborers (47-2061) | 20% | $19.51 | $22.32 | $25.51 | $22.66 | 0.98 | state |
