Which Massachusetts city is cheapest for attic insulation?
1 of the 6 metros sit above the statewide midpoint of $2,550, and the top-to-bottom gap is 3%. 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 |
|---|---|---|---|
| Boston, MA | $1,050 – $4,100 | $2,550 | +1% |
| Springfield, MA | $1,000 – $4,000 | $2,500 | −1% |
| Worcester, MA | $1,000 – $4,000 | $2,500 | −1% |
| Barnstable, MA | $1,000 – $4,000 | $2,500 | −2% |
| Amherst, MA | $1,000 – $4,000 | $2,500 | −2% |
| Pittsfield, MA | $990 – $3,950 | $2,450 | −3% |
Why two Massachusetts 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.

Each project weights the trades differently, so Massachusetts's wage level does not push every price by the same amount. Compared with the US midpoint, roof replacement is +19% and gutters +12%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Roof replacement | 2,000 sq ft of roof | $7,500 – $14,700 | +19% |
| Metal roof | 2,000 sq ft of roof | $12,700 – $37,400 | +18% |
| Vinyl siding | 2,100 sq ft of wall | $9,550 – $28,600 | +13% |

| Gutters | 160 linear ft | $1,500 – $4,650 | +12% |
Wages behind the Massachusetts number
Massachusetts'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 1.07 times the national level.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $23.53 an hour, which is in line with the national $23.62. The middle half of them earn between $22.83 and $27.87 an hour. BLS counts 710 of them working in the state, 2.0 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 $30.48 an hour, which is 35% above the national $22.66. The middle half of them earn between $25.16 and $42.46 an hour. BLS counts 16,210 of them working in the state, 44.6 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($27.87 an hour) would add about $130 to the statewide midpoint; one at the 25th percentile ($22.83) would take off about $20. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 3,637,650 jobs across Massachusetts (May 2025), which is 2.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $22.83 | $23.53 | $27.87 | $23.62 | 1.00 | state |
| Construction laborers (47-2061) | 20% | $25.16 | $30.48 | $42.46 | $22.66 | 1.35 | state |
