Los Angeles 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 Los Angeles is 1.04 times the national level.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $23.30 an hour, in line with the US median of $23.62. The middle half of them earn between $21.78 and $32.20 an hour. About 830 work in the metro. That is 1.3 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 $28.28 an hour, 25% above the US median of $22.66. The middle half of them earn between $22.75 and $37.31 an hour. About 21,730 work in the metro. That is 34.6 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
Quotes come from real crews, not medians. If the insulation workers, floor, ceiling and wall on your job are paid at the 75th percentile ($32.20 an hour) instead of the median, the labor line grows by about $270. At the 25th percentile ($21.78) it shrinks by about $45. The total moves by 10.3% or 1.8%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 6,271,560 jobs in the Los Angeles-Long Beach-Anaheim area. That makes it the 2nd largest of the 300 metros we cover, with 4.03% of US employment.
