Where the Honolulu price comes from
Labor is 36% of the midpoint bill here, against 36% nationally. The mix of trades behind this job is insulation workers, floor, ceiling and wall (80%), construction laborers (20%). We weight each trade's local median wage by that share and compare it with the national median. In Honolulu the blended ratio comes out at 1.13. BLS does not publish this trade for the area, so we used the national median.
Materials are scaled with BEA's regional price parity for goods. Honolulu is at 111.6 against 100 for the US, so a materials line of $1,600 nationally becomes $1,800 here (midpoint, 1,000 sq ft). Permits follow the all-items index of 111.0: $0 to $0.
Data note: 80% of the labor weighting for this project uses a national median because BLS has no published metro figure for that trade in Honolulu. The wage table below marks each row.

Air sealing and fixture damming
Sealing gaps and damming around recessed lights are part of what moves the price within a type.
Honolulu: what basic, standard and premium work costs
The cited range is split into basic, standard and premium bands, then scaled to Honolulu. Bands overlap, because plenty of standard jobs cost as much as a light premium one. Sizes run from small attic (600 sq ft) to large attic (1,800 sq ft).
Basic
$1,100 to $2,450
Blown-in fiberglass or cellulose to code R-value
Standard
$2,150 to $3,450
Higher R-value with air sealing around fixtures
Premium
$3,150 to $4,500
Spray foam or heavy air sealing, hard-to-reach attic
| Size | Basic | Standard | Premium |
|---|---|---|---|
| small attic (600 sq ft) | $670 – $1,500 | $1,300 – $2,100 | $1,900 – $2,700 |
| average attic (1,000 sq ft) | $1,100 – $2,450 | $2,150 – $3,450 | $3,150 – $4,500 |
| large attic (1,800 sq ft) | $2,000 – $4,450 | $3,850 – $6,250 | $5,650 – $8,050 |
Who does the work: Honolulu trade wages
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 Honolulu the blend is 1.13.
Insulation workers, floor, ceiling and wall (47-2131) carry 80% of the labor weighting. BLS does not publish this trade for the Honolulu metro, so we used the national median: $23.62 an hour against $23.62 for the US. The middle half of them earn between $20.77 and $29.32 an hour.
For construction laborers (47-2061, weighted 20%) the local median is $37.48 an hour, which is 65% above the national $22.66. The middle half of them earn between $24.21 and $41.41 an hour. BLS counts 3,040 of them working in the area, 68.1 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 $170 to the midpoint estimate; the 25th percentile takes off about $85. That is a swing of roughly 3.1% to 6.2% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Urban Honolulu has 446,380 jobs in total (BLS, May 2025), ranking 56th by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $20.77 | $23.62 | $29.32 | $23.62 | 1.00 | US |
