Concrete slab cost in Winchester, VA

Winchester 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, Winchester (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 Winchester are April through October: 7 of 12. Outside them, January, February, March, 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.

Winchester gets about 41 inches of precipitation in a normal year, including roughly 23 inches of snow. The wettest months are May, June and September (4.2 inches in May). Inside the workable window, August and October are the driest, at 3.2 and 3.0 inches. The station averages about 24 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 Winchester

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 Winchester the blend is 0.85.

Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $22.86 an hour, 17% below the US median of $27.41. The middle half of them earn between $18.55 and $26.03 an hour. About 110 work in the metro. That is 16.2 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 $20.27 an hour, which is 11% below the national $22.66. The middle half of them earn between $17.65 and $22.22 an hour. BLS counts 350 of them working in the area, 51.7 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.

Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $24.42 an hour, 15% below the US median of $28.78. The middle half of them earn between $22.02 and $28.46 an hour. About 260 work in the metro. That is 38.4 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 $24.12 an hour, 17% below the US median of $29.12. The middle half of them earn between $21.03 and $29.21 an hour. About 270 work in the metro. That is 39.9 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 $95 to the midpoint estimate; the 25th percentile takes off about $130. That is a swing of roughly 3.6% to 2.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Winchester has 67,740 jobs in total (BLS, May 2025), ranking 267th by size among the 300 metros on this site.

Specs and site conditions that change a Winchester bid

• Finish

  A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.

• Thickness and mix

  A 4-inch slab uses about 1.23 cubic yards of concrete per 100 sq ft; a 6-inch slab uses about 1.85. Stepping up from a 3,000 PSI to a 4,000-4,500 PSI mix adds $10-$40 per cubic yard (Estimators.us).

• 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.
