Vallejo labor market for composite deck
Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Vallejo is 1.27 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $36.64 an hour, which is 26% above the national $29.12. The middle half of them earn between $29.37 and $43.86 an hour. BLS counts 660 of them working in the area, 45.8 for every 10,000 jobs (US: 43.1), so the local bench is about average.
Construction laborers (47-2061), 20% of the weighting: a median of $30.05 an hour, 33% above the US median of $22.66. The middle half of them earn between $24.06 and $37.35 an hour. About 1,080 work in the metro. That is 74.9 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($43.86 an hour) instead of the median, the labor line grows by about $2,150. At the 25th percentile ($29.37) it shrinks by about $2,150. The total moves by 10.0% or 10.1%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 144,130 jobs in the Vallejo area. That makes it the 158th largest of the 300 metros we cover, with 0.09% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

Optional extras in Vallejo
Extras are quoted nationally and then scaled to Vallejo by the average of the local wage index (1.27) and goods index (1.05), a factor of 1.16. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.
| Add-on | Local range |
|---|---|
| Add a deck railing (approx. 0.3 ft per sq ft) | $2,100 – $6,250 |

Why two Vallejo quotes can differ
Board grade
Composite materials run $16-$32 per sq ft and the installed price is $40-$80 per sq ft, including the substructure (HomeGuide).
Labor
Labor for composite is $24-$48 per sq ft, higher than wood because the boards need extra parts and more careful assembly.
Drainage
Ground-level decks over poorly draining yards may need $1,000-$4,000 of drainage work first.

Climate in Vallejo: timing your composite deck job
We use NOAA's 1991-2020 climate normals for Napa Co Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
Weather is not a serious constraint for exterior installation in Vallejo: 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.
Vallejo gets about 20 inches of precipitation in a normal year. The wettest months are January, February and December (4.2 inches in January). The station averages about 16 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.
