Phoenix labor market for attic insulation
Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Phoenix is 0.89 times the national level.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $20.35 an hour, 14% below the US median of $23.62. The middle half of them earn between $20.29 and $24.46 an hour. About 550 work in the metro. That is 2.3 per 10,000 jobs, compared with 2.9 nationally, so expect fewer local crews to bid.
Construction laborers (47-2061), 20% of the weighting: a median of $22.56 an hour, in line with the US median of $22.66. The middle half of them earn between $19.79 and $24.90 an hour. About 29,230 work in the metro. That is 123.0 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
Quotes come from real crews, not medians.

At the 25th percentile ($20.29) it shrinks by about $0. The total moves by 5.4% or 0.1%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 2,375,760 jobs in the Phoenix-Mesa-Chandler area. That makes it the 11th largest of the 300 metros we cover, with 1.53% of US employment.
