Concrete slab cost in Spartanburg, SC

Spartanburg 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, Spartanburg 3 Sse (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 Spartanburg are April through June and August through October: 6 of 12. Outside them, January, February, March, November and December have an average overnight low of 40°F or below, and July has an average daytime high of 90°F or more.

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.

Heat matters for concrete as well. With average highs of 90°F or more in July, crews often start early, wet the base and plan for faster set times.

Spartanburg gets about 50 inches of precipitation in a normal year. The wettest months are March, June and December (4.8 inches in March). Inside the workable window, May and September are the driest, at 3.9 and 3.6 inches. The station averages about 57 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 Spartanburg

• 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.

• Finish

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

Pick a size, pick a tier: concrete slab pricing in Spartanburg

The cited range is split into basic, standard and premium bands, then scaled to Spartanburg. 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 Spartanburg

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 Spartanburg the blend is 0.86.

Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $23.14 an hour, 16% below the US median of $27.41. The middle half of them earn between $22.89 and $29.24 an hour. About 110 work in the metro. That is 6.7 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.

For construction laborers (47-2061, weighted 30%) the local median is $20.29 an hour, which is 10% below the national $22.66. The middle half of them earn between $17.77 and $23.33 an hour. BLS counts 1,310 of them working in the area, 79.3 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 $23.53 an hour, 18% below the US median of $28.78. The middle half of them earn between $20.29 and $28.72 an hour. About 650 work in the metro. That is 39.4 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 $24.88 an hour, 15% below the US median of $29.12. The middle half of them earn between $22.32 and $29.04 an hour. About 300 work in the metro. That is 18.2 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.

A quick sensitivity check: moving the lead trade (cement masons and concrete finishers) from the median to the 75th percentile wage adds about $180 to the midpoint estimate; the 25th percentile takes off about $5. That is a swing of roughly 0.2% to 5.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Spartanburg has 165,150 jobs in total (BLS, May 2025), ranking 143rd by size among the 300 metros on this site.
