Arizona labor market for attic insulation
Arizona'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 0.88 times the national level.
For insulation workers, floor, ceiling and wall (47-2131, weighted 80%) the local median is $20.29 an hour, which is 14% below the national $23.62. The middle half of them earn between $18.39 and $23.20 an hour. BLS counts 780 of them working in the state, 2.4 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 $22.40 an hour, which is in line with the national $22.66. The middle half of them earn between $19.04 and $24.82 an hour. BLS counts 37,630 of them working in the state, 116.2 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 ($23.20 an hour) would add about $90 to the statewide midpoint; one at the 25th percentile ($18.39) would take off about $60. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 3,239,430 jobs across Arizona (May 2025), which is 2.1% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $18.39 | $20.29 | $23.20 | $23.62 | 0.86 | state |

Basic, standard or premium: Arizona 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
$920 to $2,050
Blown-in fiberglass or cellulose to code R-value
Standard
$1,750 to $2,900
Higher R-value with air sealing around fixtures
Premium
$2,600 to $3,750
Spray foam or heavy air sealing, hard-to-reach attic
| Size | Basic | Standard | Premium |
|---|---|---|---|
| small attic (600 sq ft) | $550 – $1,200 | $1,050 – $1,750 | $1,550 – $2,250 |
| average attic (1,000 sq ft) | $920 – $2,050 | $1,750 – $2,900 | $2,600 – $3,750 |
| large attic (1,800 sq ft) | $1,650 – $3,650 | $3,150 – $5,200 | $4,700 – $6,700 |
Why two Arizona 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.
Arizona versus the states around it
Arizona ranks 48 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. Arizona sits at $2,300.

Which Arizona city is cheapest for attic insulation?
2 of the 6 metros sit above the statewide midpoint of $2,300, and the top-to-bottom gap is 4%. 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.

|---|---|---|---|
| Flagstaff, AZ | $920 – $3,750 | $2,350 | +1% |
| Prescott Valley, AZ | $920 – $3,750 | $2,350 | +1% |
