New Haven 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 New Haven is 1.05 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 New Haven metro, so we used the Connecticut statewide median: $23.34 an hour against $23.62 for the US. The middle half of them earn between $19.41 and $26.77 an hour.
Construction laborers (47-2061), 20% of the weighting: a median of $29.02 an hour, 28% above the US median of $22.66. The middle half of them earn between $23.36 and $35.51 an hour. About 1,220 work in the metro. That is 43.4 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 ($26.77 an hour) instead of the median, the labor line grows by about $100. At the 25th percentile ($19.41) it shrinks by about $120. The total moves by 4.2% or 4.8%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 281,410 jobs in the New Haven area. That makes it the 91st largest of the 300 metros we cover, with 0.18% of US employment.
