If you are planning more than one job in Oregon
Each project weights the trades differently, so Oregon's wage level does not push every price by the same amount. Compared with the US midpoint, window replacement is +8% and vinyl siding +6%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Roof replacement | 2,000 sq ft of roof | $6,500 – $13,200 | +6% |
| Metal roof | 2,000 sq ft of roof | $11,000 – $34,800 | +7% |

| Gutters | 160 linear ft | $1,400 – $4,500 | +8% |
Basic, standard or premium: Oregon prices
Bands overlap on purpose, since a good standard job can cost as much as a light premium one. Below are the three bands for the default size, then a grid from small attic (600 sq ft) to large attic (1,800 sq ft).
Basic
$1,100 to $2,450
Blown-in fiberglass or cellulose to code R-value
Standard
$2,100 to $3,400
Higher R-value with air sealing around fixtures
Premium
$3,100 to $4,400
Spray foam or heavy air sealing, hard-to-reach attic
| Size | Basic | Standard | Premium |
|---|---|---|---|
| small attic (600 sq ft) | $670 – $1,450 | $1,250 – $2,050 | $1,850 – $2,650 |
| average attic (1,000 sq ft) | $1,100 – $2,450 | $2,100 – $3,400 | $3,100 – $4,400 |
| large attic (1,800 sq ft) | $2,000 – $4,400 | $3,800 – $6,150 | $5,550 – $7,900 |
Oregon metro-by-metro prices
3 of the 5 metros sit above the statewide midpoint of $2,750, and the top-to-bottom gap is 6%. 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 |
|---|---|---|---|
| Medford, OR | $1,200 – $4,650 | $2,900 | +6% |
| Portland, OR | $1,150 – $4,450 | $2,800 | +1% |
| Salem, OR | $1,150 – $4,400 | $2,800 | +1% |
| Bend, OR | $1,150 – $4,400 | $2,750 | level |
| Eugene, OR | $1,100 – $4,400 | $2,750 | level |
Why two Oregon 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.
Oregon versus the states around it
Oregon ranks 4 of 51 (the 50 states plus DC) for attic insulation, where 1 is the most expensive. The costliest is Washington at $2,900 and the cheapest West Virginia at $2,250, both for 1,000 sq ft at the midpoint. Oregon sits at $2,750. The five states closest by workforce center are listed below.
| State | Distance | Range | Midpoint | vs. here |
|---|---|---|---|---|
| Washington | 170 miles away | $1,200 – $4,550 | $2,900 | +4% |
| Idaho | 350 miles away | $920 – $3,750 | $2,350 | −16% |

Oregon labor market for attic insulation
Oregon'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 1.20 times the national level.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $28.95 an hour, which is 23% above the national $23.62. The middle half of them earn between $23.79 and $34.84 an hour. BLS counts 700 of them working in the state, 3.6 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 $24.45 an hour, which is 8% above the national $22.66. The middle half of them earn between $21.65 and $29.91 an hour. BLS counts 12,620 of them working in the state, 64.2 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 ($34.84 an hour) would add about $180 to the statewide midpoint; one at the 25th percentile ($23.79) would take off about $160. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 1,967,130 jobs across Oregon (May 2025), which is 1.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $23.79 | $28.95 | $34.84 | $23.62 | 1.23 | state |
| Construction laborers (47-2061) | 20% | $21.65 | $24.45 | $29.91 | $22.66 | 1.08 | state |
