Baltimore 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 Baltimore is 1.23 times the national level.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $30.39 an hour, 29% above the US median of $23.62. The middle half of them earn between $23.68 and $31.65 an hour. About 550 work in the metro. That is 4.1 per 10,000 jobs, compared with 2.9 nationally, which suggests plenty of local crews to bid.
Construction laborers (47-2061), 20% of the weighting: a median of $22.34 an hour, in line with the US median of $22.66. The middle half of them earn between $18.72 and $26.66 an hour.

Quotes come from real crews, not medians. If the insulation workers, floor, ceiling and wall on your job are paid at the 75th percentile ($31.65 an hour) instead of the median, the labor line grows by about $40. At the 25th percentile ($23.68) it shrinks by about $200. The total moves by 1.4% or 7.5%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 1,356,680 jobs in the Baltimore-Columbia-Towson area. That makes it the 22nd largest of the 300 metros we cover, with 0.87% of US employment.
