What local crews earn in San Jose
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 San Jose the blend is 1.35.
Carpenters (47-2031), 80% of the weighting: a median of $38.55 an hour, 32% above the US median of $29.12. The middle half of them earn between $30.23 and $49.38 an hour. About 4,460 work in the metro. That is 39.3 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 $32.92 an hour, which is 45% above the national $22.66. The middle half of them earn between $27.33 and $38.90 an hour. BLS counts 4,420 of them working in the area, 38.9 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 $1,450 to the midpoint estimate; the 25th percentile takes off about $1,150. That is a swing of roughly 8.4% to 11.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
San Jose-Sunnyvale-Santa Clara has 1,134,970 jobs in total (BLS, May 2025), ranking 27th by size among the 300 metros on this site.

San Jose weather and the wood deck calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, San Jose (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
Weather is not a serious constraint for exterior installation in San Jose: no month in the averages is cold enough (an average daytime high under 45°F) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
San Jose gets about 13 inches of precipitation in a normal year. The wettest months are January, February and December (2.8 inches in January). 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.
