How much does a concrete patio cost in Metairie, LA?

A concrete patio in Metairie runs $12 to $18 per square foot installed in 2026. A 300 square foot patio falls between $3,600 and $5,400. Saturated subgrade, slab thickness above 4 inches, decorative finishes, and pergola footings each push the number toward the higher end of that range.

Does Metairie clay soil cause concrete patios to crack?

Yes. The soft alluvial clay and organic silt beneath most Metairie yards compress under load over time, causing slabs without a prepared base to settle unevenly and crack. A compacted crushed limestone base 4 to 6 inches deep, combined with rebar reinforcement and proper control joints, controls that movement and extends slab life significantly.

Do I need a permit for a concrete patio in Metairie?

Permit requirements depend on the size and scope of the project. Jefferson Parish Department of Inspection and Code Enforcement is the authority for residential flatwork in Metairie, and requirements and fees change. Confirm with the parish office before work begins rather than relying on general estimates.

How long does a concrete patio last in Metairie?

A properly detailed concrete patio in Metairie, meaning a compacted limestone base, 3,500 PSI mix, rebar reinforcement, and applied sealer, lasts 25 to 40 years before requiring significant repair. Slabs poured without base preparation on native clay commonly show settlement cracking within 10 to 15 years.

What finish is best for a concrete patio in Metairie?

A broom finish is the most practical for Metairie patios because the light texture provides slip resistance in wet conditions, which are frequent here, without trapping debris the way deep exposed aggregate can. Stamped and smooth finishes are available but require more maintenance and can become slippery when wet.

Concrete Patios in Metairie, LA

A concrete patio in Metairie requires a thicker slab, heavier reinforcement, and a prepared limestone base because the soft alluvial clay and organic silt beneath Jefferson Parish yards compress over time, causing uneven settlement that cracks standard residential flatwork. The ground conditions here are not a minor variable. They are the difference between a patio that lasts 30 years and one that tilts and cracks within a decade. Every spec on this page reflects what Metairie's soil actually demands.

Full vehicle and furniture load is safe after 7 days; full cure reaches 28 days

What Does a Concrete Patio Cost in Metairie?

A concrete patio in Metairie runs $12 to $18 per square foot installed in 2026, putting a typical 300 square foot patio between $3,600 and $5,400 and a 500 square foot patio between $6,000 and $9,000. Four variables move that range.

Subgrade condition: saturated or organic soil requires deeper excavation and more base material, adding $1 to $2 per square foot
Slab thickness: stepping from 4 inches to 5 inches adds roughly $0.80 per square foot in concrete alone
Finish: a broom finish is the baseline; exposed aggregate or stamped patterns add $3 to $6 per square foot
Pergola footings: each isolated footing for a pergola or shade structure adds $180 to $320 depending on depth and diameter

What Does Metairie Ground Demand for a Concrete Patio?

Metairie's soft alluvial clay and organic silt compress under load, so the subgrade preparation for a concrete patio here is more involved than the national standard. The water table sits 2 to 5 feet below grade across most of Metairie, which means the native soil retains moisture year-round and never fully consolidates.

Subgrade and Base

Native clay is removed to a depth of 6 to 8 inches across the patio footprint. That material is replaced with 4 to 6 inches of crushed limestone, compacted in two lifts to a minimum of 95 percent Proctor density. Compacted limestone resists the lateral movement that saturated clay allows. A 6-mil polyethylene vapor barrier is placed over the compacted base before the pour.

Slab and Reinforcement

Slab thickness is 4 inches at minimum and 5 inches where pergola footings or heavy furniture loads are anticipated. The concrete mix is 3,500 PSI minimum. Reinforcement is #3 rebar on 18-inch centers throughout, tied at intersections. Control joints are cut or tooled every 8 to 10 feet in both directions within 12 hours of the pour to direct any shrinkage cracking to a predictable line.

Drainage

Every Metairie patio is finished with a drainage slope of at least 1/8 inch per foot, directed away from the house foundation. Where the yard has no natural fall, a channel drain at the patio perimeter carries runoff to an appropriate outlet. Standing water on a slab accelerates sealer breakdown and, over time, erodes the limestone base through repeated saturation and drying.

How Does the Job Run in Metairie?

A standard 400 square foot patio in Metairie takes 3 to 4 days from excavation to finishing. Day one covers layout, excavation to subgrade, and base material delivery. Day two is compaction of the limestone base in two lifts, vapor barrier placement, and rebar installation. The pour and finishing occur on day three. If the native clay is saturated at excavation depth, a portable dewatering pump runs during base preparation to keep the work area stable. Sealer is applied on day four or five, once the surface has cured sufficiently to resist penetration.

Recent Concrete Patio Project in Metairie

Backyard patio replacement, East Metairie

The existing 380 square foot slab had settled 1.5 inches on the yard side over roughly 15 years, directing rainwater back toward the house foundation. The original subgrade had no base course. The old slab was removed and the native clay excavated to 8 inches. Six inches of crushed limestone went in, compacted in two passes. The new 5-inch slab used 3,500 PSI concrete with #3 rebar on 18-inch centers, finished with a broom texture and sealed 4 days after the pour. Drainage slope was set at 3/16 inch per foot away from the foundation. The job ran 4 days.

Common Questions from Metairie Homeowners About Concrete Patios

Does Metairie soil require a thicker slab than a standard 4-inch pour?

On most Metairie lots, 4 inches is the minimum and 5 inches is the practical standard when the subgrade shows high moisture or the patio will carry a pergola or heavy planters. The organic silt common in Jefferson Parish compresses under sustained load, and the extra inch of concrete adds resistance to flexural cracking without a large cost increase.

How long before I can use the patio after the pour?

Foot traffic is safe at 24 to 48 hours after the pour. Furniture and normal use are safe at 7 days. Full cure, at which point the slab reaches rated strength, takes 28 days. Applying sealer before 4 days post-pour traps bleed water and compromises adhesion.

Should I seal a new concrete patio in Metairie?

Sealing a Metairie patio is strongly advisable given the rainfall and humidity levels here. A penetrating silane-siloxane sealer applied at 4 to 7 days post-pour reduces moisture absorption by up to 95 percent, which slows surface scaling and extends the useful life of the slab. Reapplication every 3 to 5 years maintains that protection.
