Add-ons priced for Louisiana
Extras are quoted nationally and then scaled to Louisiana by the average of the local wage index (0.84) and goods index (0.94), a factor of 0.89. 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.
| Add-on | Local range |
|---|---|
| Add rebar reinforcement | $360 – $1,050 |
| Remove old concrete first | $710 – $2,150 |

Concrete slab: what moves the price in Louisiana
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.
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.
Quality levels and sizes in Louisiana
The cited range is cut into three overlapping bands (basic, standard and premium) and scaled to statewide Louisiana wages and prices. The grid prices the same bands at 5 common sizes.
Basic
$2,200 to $3,150
4-inch broom-finish slab, light mesh, easy truck access
Standard
$2,950 to $3,900
4-5 inch slab with rebar or heavier mesh and standard base prep
Premium
$3,650 to $4,650
6-inch slab, heavy reinforcement, thick base, pump truck or tight access
| Size | Basic | Standard | Premium |
|---|---|---|---|
| 10x10 pad (100 sq ft) | $580 – $920 | $830 – $1,150 | $1,100 – $1,450 |
| 12x12 (144 sq ft) | $810 – $1,250 | $1,150 – $1,600 | $1,450 – $1,900 |
| 20x20 (400 sq ft) | $2,200 – $3,150 | $2,950 – $3,900 | $3,650 – $4,650 |
| 24x24 garage floor (576 sq ft) | $3,100 – $4,500 | $4,150 – $5,550 | $5,200 – $6,550 |
| 30x40 foundation (1,200 sq ft) | $6,450 – $9,200 | $8,500 – $11,200 | $10,600 – $13,300 |
Louisiana metro-by-metro prices
4 of the 9 metros sit above the statewide midpoint of $3,400, and the top-to-bottom gap is 11%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (400 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Baton Rouge, LA | $2,350 – $4,950 | $3,650 | +6% |
| Lafayette, LA | $2,200 – $4,750 | $3,500 | +2% |

When Louisiana weather lets you pour
Season matters for concrete slab. For each Louisiana metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for pouring concrete.
New Orleans has the longest comfortable season of the metros we cover in Louisiana at 10 months (September through June); Monroe has the shortest at 6 (March through May and September through November). Rainfall runs from 51 inches a year in Shreveport to 66 inches in Slidell.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| New Orleans | 47 | 91 | 60 | 10: September through June |
| Baton Rouge | 42 | 92 | 62 | 9: September through May |
| Lafayette | 44 | 92 | 63 | 9: September through May |
| Shreveport | 37 | 94 | 51 | 6: February through May and October through November |
| Lake Charles | 43 | 92 | 60 | 9: September through May |

Wages behind the Louisiana number
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 4 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.84 for Louisiana.
For cement masons and concrete finishers (47-2051, weighted 50%) the local median is $23.64 an hour, which is 14% below the national $27.41. The middle half of them earn between $19.54 and $30.00 an hour. BLS counts 910 of them working in the state, 4.7 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 $18.38 an hour, 19% below the US median of $22.66. The middle half of them earn between $16.59 and $22.74 an hour. About 22,100 work in the state. That is 114.2 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 $24.86 an hour, which is 14% below the national $28.78. The middle half of them earn between $22.33 and $29.92 an hour. BLS counts 7,860 of them working in the state, 40.6 for every 10,000 jobs (US: 30.7), so the local bench is deeper than average.
For carpenters (47-2031, weighted 10%) the local median is $24.00 an hour, which is 18% below the national $29.12. The middle half of them earn between $21.03 and $28.72 an hour. BLS counts 8,990 of them working in the state, 46.5 for every 10,000 jobs (US: 43.1), so the local bench is about average.
A crew paid at the 75th percentile for cement masons and concrete finishers ($30.00 an hour) would add about $190 to the statewide midpoint; one at the 25th percentile ($19.54) would take off about $120. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 1,934,900 jobs across Louisiana (May 2025), which is 1.2% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Cement masons and concrete finishers (47-2051) | 50% | $19.54 | $23.64 | $30.00 | $27.41 | 0.86 | state |
| Construction laborers (47-2061) | 30% | $16.59 | $18.38 | $22.74 | $22.66 | 0.81 | state |
