Why Kahului prices look the way they do
The wage side of the estimate leans on glaziers, who do 50% of the hours on a typical job. Their local median is $38.85 an hour. Add the other trades involved and the blended wage index for Kahului is 1.38 (US = 1.00), which puts labor at 32% of the total. BLS does not publish this trade for the metro, so we used the Hawaii statewide median.
Materials are scaled with BEA's regional price parity for goods. Kahului is at 111.6 against 100 for the US, so a materials line of $7,100 nationally becomes $7,900 here (midpoint, 10 windows). Permits follow the all-items index of 109.4: $0 to $0.
Data note: 50% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Kahului. The wage table below marks each row.
Kahului weather and the window replacement calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Kahului Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in Kahului are October through July: 10 of 12. Outside them, August and September have an average daytime high of 90°F or more.
Kahului gets about 16 inches of precipitation in a normal year. The wettest months are January, March and December (2.8 inches in December). Inside the workable window, June and July are the driest, at 0.2 and 0.5 inches. The station averages about 39 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.

What local crews earn in Kahului
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 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 Kahului the blend is 1.38.
Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for the Kahului metro, so we used the Hawaii statewide median: $38.85 an hour against $27.44 for the US. The middle half of them earn between $29.04 and $48.30 an hour.
Carpenters (47-2031), 40% of the weighting: a median of $39.47 an hour, 36% above the US median of $29.12. The middle half of them earn between $30.77 and $48.89 an hour. About 700 work in the metro. That is 94.9 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For general maintenance and repair workers (49-9071, weighted 10%) the local median is $30.76 an hour, which is 29% above the national $23.84. The middle half of them earn between $27.16 and $38.06 an hour. BLS counts 1,350 of them working in the area, 183.1 for every 10,000 jobs (US: 98.4), so the local bench is deeper than average.
A quick sensitivity check: moving the lead trade (glaziers) from the median to the 75th percentile wage adds about $460 to the midpoint estimate; the 25th percentile takes off about $480. That is a swing of roughly 4.1% to 4.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Kahului-Wailuku has 73,750 jobs in total (BLS, May 2025), ranking 250th by size among the 300 metros on this site.
