Why Flagstaff prices look the way they do

We price the labor side from BLS wage data for 2 trades: insulation workers, floor, ceiling and wall at 80%, construction laborers at 20%. Weighted together, Flagstaff wages are 0.88 times the national level. Labor makes up about 34% of the midpoint estimate (36% at national prices). BLS does not publish this trade for the metro, so we used the Arizona statewide median.

Materials are scaled with BEA's regional price parity for goods. Flagstaff is at 96.2 against 100 for the US, so a materials line of $1,600 nationally becomes $1,550 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 100.3: $0 to $0.

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 Flagstaff. The wage table below marks each row.

Attic insulation: what moves the price in Flagstaff

    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).

What local crews earn in Flagstaff

The labor line is built from BLS wage data, one trade at a time. This job draws on 2 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Flagstaff the blend is 0.88.

Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Flagstaff metro, so we used the Arizona statewide median: $20.29 an hour against $23.62 for the US. The middle half of them earn between $18.39 and $23.20 an hour.

For construction laborers (47-2061, weighted 20%) the local median is $22.32 an hour, which is in line with the national $22.66. The middle half of them earn between $18.61 and $24.26 an hour. BLS counts 470 of them working in the area, 70.6 for every 10,000 jobs (US: 70.5), so the local bench is about average.

A quick sensitivity check: moving the lead trade (insulation workers, floor, ceiling and wall) from the median to the 75th percentile wage adds about $90 to the midpoint estimate; the 25th percentile takes off about $60. That is a swing of roughly 2.5% to 3.8% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Flagstaff has 66,610 jobs in total (BLS, May 2025), ranking 272nd by size among the 300 metros on this site.
