Concrete slab cost in Lafayette, LA

Concrete slab: what moves the price in Lafayette

• 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.

• 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).

Add-ons priced for Lafayette

Extras are quoted nationally and then scaled to Lafayette by the average of the local wage index (0.88) and goods index (0.94), a factor of 0.91. 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.

Local wages behind the labor line

Wages are the part of this estimate that changes most from town to town. 4 trades carry the job here, and each is compared with its US median. The weighted result for Lafayette is 0.88 times the national level.

For cement masons and concrete finishers (47-2051, weighted 50%) the local median is $25.91 an hour, which is 5% below the national $27.41. The middle half of them earn between $20.29 and $30.00 an hour. BLS counts 90 of them working in the area, 5.0 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.

Construction laborers (47-2061), 30% of the weighting: a median of $18.57 an hour, 18% below the US median of $22.66. The middle half of them earn between $16.31 and $22.95 an hour. About 1,780 work in the metro. That is 99.1 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.

For operating engineers and other construction equipment operators (47-2073, weighted 10%) the local median is $23.94 an hour, which is 17% below the national $28.78. The middle half of them earn between $22.27 and $29.10 an hour. BLS counts 370 of them working in the area, 20.6 for every 10,000 jobs (US: 30.7), so the local bench is thinner than average.

For carpenters (47-2031, weighted 10%) the local median is $22.81 an hour, which is 22% below the national $29.12. The middle half of them earn between $18.55 and $27.69 an hour. BLS counts 580 of them working in the area, 32.3 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.

Quotes come from real crews, not medians. If the cement masons and concrete finishers on your job are paid at the 75th percentile ($30.00 an hour) instead of the median, the labor line grows by about $120. At the 25th percentile ($20.29) it shrinks by about $160. The total moves by 3.4% or 4.7%, so wages alone rarely explain a quote that is far outside our range.

For context on the local economy, BLS counts 179,570 jobs in the Lafayette area. That makes it the 129th largest of the 300 metros we cover, with 0.12% of US employment.

When to schedule concrete slab in Lafayette

We use NOAA's 1991-2020 climate normals for Lafayette Rgnl Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.

September through May is the stretch where pouring concrete runs into the fewest weather problems in Lafayette (9 of 12 months). 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.

Lafayette gets about 63 inches of precipitation in a normal year. The wettest months are June, July and August (7.1 inches in June). Inside the workable window, February and March are the driest, at 4.1 and 3.7 inches. The station averages about 91 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.
