Data note: 80% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Durham. The wage table below marks each row.

Durham 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 Durham is 0.90 times the national level.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Durham metro, so we used the North Carolina statewide median: $20.67 an hour against $23.62 for the US. The middle half of them earn between $17.49 and $23.07 an hour.
Construction laborers (47-2061), 20% of the weighting: a median of $22.38 an hour, in line with the US median of $22.66. The middle half of them earn between $19.03 and $25.15 an hour. About 1,120 work in the metro. That is 32.6 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 ($23.07 an hour) instead of the median, the labor line grows by about $75. At the 25th percentile ($17.49) it shrinks by about $95. The total moves by 3.1% or 4.1%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 344,020 jobs in the Durham-Chapel Hill area. That makes it the 74th largest of the 300 metros we cover, with 0.22% of US employment.
