Why Denver prices look the way they do

The wage side of the estimate leans on insulation workers, floor, ceiling and wall, who do 80% of the hours on a typical job. Their local median is $24.87 an hour. Add the other trades involved and the blended wage index for Denver is 1.05 (US = 1.00), which puts labor at 37% of the total.

On the materials line, the BEA goods price index for the Denver metro is 101.0 (US = 100). The midpoint materials bill for 1,000 sq ft comes to $1,600, compared with $1,600 at national prices. Permit and inspection fees are scaled by the broader index (105.8) and land at $0 to $0.

Attic insulation: what moves the price in Denver

  • Air sealing and fixture damming

    Sealing gaps and damming around recessed lights are part of what moves the price within a type.

  • Removing old insulation

    Old, wet or pest-damaged insulation has to come out first, at extra cost.

  • Type of insulation

    Blown-in is $0.90-$2.40 per sq ft and loose-fill is $1.00-$2.50 installed; spray foam costs more (HomeGuide).

Denver 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 Denver is 1.05 times the national level.

Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $24.87 an hour, 5% above the US median of $23.62. The middle half of them earn between $23.42 and $30.47 an hour. About 730 work in the metro. That is 4.5 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 $23.44 an hour, 3% above the US median of $22.66. The middle half of them earn between $21.48 and $27.44 an hour. About 9,650 work in the metro. That is 60.0 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.

Quotes come from real crews, not medians. If the insulation workers, floor, ceiling and wall on your job are paid at the 75th percentile ($30.47 an hour) instead of the median, the labor line grows by about $170. At the 25th percentile ($23.42) it shrinks by about $45. The total moves by 6.7% or 1.7%, so wages alone rarely explain a quote that is far outside our range.

For context on the local economy, BLS counts 1,609,350 jobs in the Denver-Aurora-Centennial area. That makes it the 17th largest of the 300 metros we cover, with 1.03% of US employment.
