What is behind the Milwaukee number
Labor is 63% of the midpoint bill here, against 60% nationally. The mix of trades behind this job is carpenters (80%), construction laborers (20%). We weight each trade's local median wage by that share and compare it with the national median. In Milwaukee the blended ratio comes out at 1.09.
Materials are scaled with BEA's regional price parity for goods. Milwaukee is at 93.8 against 100 for the US, so a materials line of $7,200 nationally becomes $6,750 here (midpoint, 300 sq ft). Permits follow the all-items index of 96.9: $50 to $150.
What local crews earn in Milwaukee
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 Milwaukee the blend is 1.09.
Carpenters (47-2031), 80% of the weighting: a median of $30.73 an hour, 6% above the US median of $29.12. The middle half of them earn between $26.48 and $39.60 an hour. About 3,310 work in the metro. That is 40.3 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 20%) the local median is $27.61 an hour, which is 22% above the national $22.66. The middle half of them earn between $22.17 and $37.52 an hour. BLS counts 4,740 of them working in the area, 57.7 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $2,650 to the midpoint estimate; the 25th percentile takes off about $1,250. That is a swing of roughly 6.8% to 14.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Milwaukee-Waukesha has 820,780 jobs in total (BLS, May 2025), ranking 38th by size among the 300 metros on this site.

Milwaukee weather and the composite deck calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Mt Mary College (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 Milwaukee are April through November: 8 of 12. Outside them, January, February, March and December have an average daytime high under 45°F.
In January, February, March and December the average high stays below 45°F. Sealants, adhesives and some materials, such as vinyl, are harder to install well in the cold, and short daylight cuts the working day.
Milwaukee gets about 34 inches of precipitation in a normal year, including roughly 40 inches of snow. The wettest months are April, May and June (4.8 inches in June). Inside the workable window, October and November are the driest, at 2.7 and 2.0 inches. The station averages about 16 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.
