Vallejo weather and the concrete slab calendar

Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Napa Co Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.

For pouring concrete, the comfortable months in Vallejo are March through October: 8 of 12. Outside them, January, February, November and December have an average overnight low of 40°F or below.

The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.

Vallejo gets about 20 inches of precipitation in a normal year. The wettest months are January, February and December (4.2 inches in January). Inside the workable window, July and August are the driest, at 0.0 and 0.0 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.

Concrete slab: what moves the price in Vallejo

• Base and reinforcement

  A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.

• Truck and pump access

  If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.

• Small-job minimums

  Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.

Cost by quality level and size in Vallejo

The cited range is split into basic, standard and premium bands, then scaled to Vallejo. Bands overlap, because plenty of standard jobs cost as much as a light premium one. Sizes run from 10x10 pad (100 sq ft) to 30x40 foundation (1,200 sq ft).

What local crews earn in Vallejo

The labor line is built from BLS wage data, one trade at a time. This job draws on 4 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 Vallejo the blend is 1.22.

Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $29.42 an hour, 7% above the US median of $27.41. The middle half of them earn between $23.59 and $36.88 an hour. About 420 work in the metro. That is 29.1 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.

For construction laborers (47-2061, weighted 30%) the local median is $30.05 an hour, which is 33% above the national $22.66. The middle half of them earn between $24.06 and $37.35 an hour. BLS counts 1,080 of them working in the area, 74.9 for every 10,000 jobs (US: 70.5), so the local bench is about average.

Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $45.72 an hour, 59% above the US median of $28.78. The middle half of them earn between $34.44 and $59.84 an hour. About 630 work in the metro. That is 43.7 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.

Carpenters (47-2031), 10% of the weighting: a median of $36.64 an hour, 26% above the US median of $29.12. The middle half of them earn between $29.37 and $43.86 an hour. About 660 work in the metro. That is 45.8 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.

A quick sensitivity check: moving the lead trade (cement masons and concrete finishers) from the median to the 75th percentile wage adds about $220 to the midpoint estimate; the 25th percentile takes off about $170. That is a swing of roughly 4.0% to 5.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Vallejo has 144,130 jobs in total (BLS, May 2025), ranking 158th by size among the 300 metros on this site.
