How Much Does a Concrete Patio Cost in Louisiana?

A plain concrete patio with a broom finish costs about $5 to $13 a square foot in 2026 cost guides. One national cost calculator prices a basic 12 by 12 patio at $1,350 to $1,650 for a Lafayette ZIP code.

Stamped and other decorative finishes often cost about twice as much. Tearing out an old patio first adds about $2 to $6 a square foot, national cost guides say. These are market numbers, not our price list. We pour concrete patios and walkways around Lafayette with a broom finish, and every quote comes in writing.

What does a concrete patio cost by size?

Size sets most of the price. The table shows that calculator’s September 2026 figures for a Lafayette ZIP code, rounded to the nearest $10.

The figures cover the forms, the reinforcing, the pour and a broom finish on an easy site. They assume fiber-reinforced concrete at least 4 inches thick. Digging and a gravel base cost extra, and so does tear-out.

Every Acadiana and Baton Rouge ZIP code we tried gets these figures, about 9 percent under the calculator’s national average. Bigger patios cost less per square foot, because some costs are the same on any job. A 10 by 10 runs about $10.00 to $12.33 a square foot. A 20 by 20 runs about $8.52 to $10.23.

National figures run wider. A national concrete cost guide from January 2026 lists $900 to $3,000 for a 12 by 12 patio. Its 20 by 20 range is $3,200 to $7,200, labor and materials included. A national home-services marketplace says most people pay around $3,541 for a concrete patio.

What drives the price of a concrete patio?

Thickness. Most patio prices assume a slab 4 inches thick. The Lafayette Consolidated Government sets that same 4 inches as the minimum for public sidewalks. A national marketplace’s July 2026 figures put a 356-square-foot patio at $2,785 at 4 inches. At 6 inches, the same patio comes to $3,479.

Dirt work and base. The basic prices above assume light grading on an easy site. For a 12 by 12, adding hand digging raises the calculator’s Lafayette figure about $250 to $300.

Access and porch slabs. A national concrete cost guide says costs rise when a pump or extra labor is needed to reach the site. A slab under an existing porch roof is a common example. The concrete often goes in by wheelbarrow or pump line, and the forms have to fit around the posts.

Labor. Labor costs more than the concrete itself. In the marketplace’s breakdown, labor ran $1,471 to $1,615 and materials ran $701 to $1,565. Ready-mix averaged about $180 a cubic yard nationwide in 2025, a national concrete price guide says. A 12 by 12 patio at 4 inches takes a little under 2 cubic yards.

A pad for a shed or a shop is a different job. Our guide to concrete slab costs in Louisiana covers those numbers.

What does it cost to tear out an old patio first?

National cost guides put concrete removal at about $2 to $6 a square foot. One guide puts concrete with no steel in it at $2 to $4, and reinforced concrete at $4 to $6. Disposal is about $0.50 to $2 of that. The same guide’s average for removing a patio is $1,000 to $2,000, depending on size.

The same national calculator assumes a hand jackhammer for removal. At a Lafayette ZIP code, it prices a 12 by 12 slab, hauled away, at about $1,520 to $1,850.

If the old patio has sunk or tilts toward the house, tearing out the old slab comes first. A patio that is still level and sound can stay, with the new section poured against it.

How much more do stamped and decorative finishes cost?

We pour patios with a broom finish. A broom drawn across the wet concrete leaves a ridged texture that resists slipping. Decorative finishes are other companies’ work. Here is what the market charges for them.

Sources: a national concrete cost guide (January 2026) and, for exposed aggregate, a national cost guide (December 2025).

In the Lafayette ZIP calculator, a stamped 12 by 12 runs about $3,100 to $3,770. That is more than twice the broom-finish price. For stamped or stained concrete, you would hire a decorative concrete company.

Why does a patio’s slope matter so much here?

The state building code, the Louisiana State Uniform Construction Code, adopts the International Residential Code. Its section R401.3 says hard surfaces within 10 feet of a house must slope at least 2 percent away. That is about a quarter inch per foot. At that slope, a patio 10 feet deep drops almost 2 and a half inches.

Rain gives that slope plenty of work. NOAA’s 1991 to 2020 normals give Lafayette’s airport about 63 inches of rain a year. June is the wettest month, at about 7 inches.

The ground is slow to soak it up. In the federal NRCS soil survey, Frost soils cover about 23 percent of Lafayette Parish, the most of any soil. The survey rates them poorly drained, and water moves through them slowly. Their wet layers start within 18 inches of the surface from December to April in most years.

Water that leaves the patio needs a path across the yard. On a flat lot, a catch basin or a channel drain at the patio edge can carry it off. That adds to the price, so plan it with the patio.

What does a walkway or sidewalk add?

Walks and sidewalks price out much like patios. For a Lafayette ZIP code, the same calculator puts a 4 by 25 foot walk at about $1,150 to $1,420. That is 100 square feet of broom-finished concrete on an easy site. Pouring a walk along with the patio spreads the setup over more square feet.

How do you get a real price for your patio?

Market ranges help you plan, but every yard is different. The real number comes after someone looks at the job. We look at your yard, or you send photos, and we put the quote in writing.
