Why Mobile prices look the way they do
We price the labor side from BLS wage data for 4 trades: cement masons and concrete finishers at 50%, construction laborers at 30%, operating engineers and other construction equipment operators at 10%, carpenters at 10%. Weighted together, Mobile wages are 0.79 times the national level. Labor makes up about 37% of the midpoint estimate (42% at national prices).
Materials are scaled with BEA's regional price parity for goods. Mobile is at 96.4 against 100 for the US, so a materials line of $2,000 nationally becomes $1,950 here (midpoint, 400 sq ft). Permits follow the all-items index of 88.1: $45 to $350.
Why two Mobile quotes can differ
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.
What nearby projects cost in Mobile
Jobs that often go together with concrete slab are priced below at their usual sizes, using the same Mobile wage and price inputs. Compared with national midpoints, detached garage comes out highest (−11%) and concrete driveway lowest (−16%); the gap comes from the trades each job uses.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete driveway | 600 sq ft | $3,150 – $7,700 | −16% |
| Concrete patio | 300 sq ft | $1,100 – $3,450 | −13% |
| Detached garage | 576 sq ft | $25,800 – $51,700 | −11% |
| Stamped concrete | 400 sq ft | $2,900 – $6,950 | −12% |
| Asphalt driveway | 600 sq ft | $2,750 – $6,550 | −11% |
| Gravel driveway | 1,000 sq ft | $2,200 – $8,950 | −13% |

The best months for concrete slab in Mobile
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Mobile Dwtn 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 Mobile are September through May: 9 of 12. Outside them, June, July and August have an average daytime high of 90°F or more.
Heat matters for concrete as well. With average highs of 90°F or more in June, July and August, crews often start early, wet the base and plan for faster set times.
Mobile gets about 61 inches of precipitation in a normal year. The wettest months are June, July and August (7.1 inches in August). Inside the workable window, February and October are the driest, at 3.8 and 3.8 inches. The station averages about 73 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.

Who does the work: Mobile trade wages
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 Mobile the blend is 0.79.
Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $21.80 an hour, 20% below the US median of $27.41. The middle half of them earn between $18.09 and $27.10 an hour. About 230 work in the metro. That is 13.3 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 30%) the local median is $17.71 an hour, which is 22% below the national $22.66. The middle half of them earn between $14.69 and $21.21 an hour. BLS counts 2,050 of them working in the area, 118.8 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $22.79 an hour, 21% below the US median of $28.78. The middle half of them earn between $21.20 and $27.09 an hour. About 990 work in the metro. That is 57.4 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 $23.34 an hour, 20% below the US median of $29.12. The middle half of them earn between $20.96 and $27.51 an hour. About 630 work in the metro. That is 36.5 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 $150 to the midpoint estimate; the 25th percentile takes off about $110. That is a swing of roughly 3.2% to 4.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Mobile has 172,550 jobs in total (BLS, May 2025), ranking 135th by size among the 300 metros on this site.
