How Much Does a Concrete Patio Cost in Marietta GA?
What’s the actual cost of a concrete patio in Marietta, GA? It depends on more than square footage — finish type, drainage requirements, site preparation depth for Georgia’s red clay, and the size of your project all move the number significantly. In this post, we cover current concrete patio pricing in Marietta for 2026, the specific factors that affect your quote, and how to evaluate estimates so you’re comparing apples to apples when multiple contractors bid your project.

Why Concrete Patio Pricing Varies in Marietta
The pricing range for concrete patios in Marietta is wide — a plain 400-square-foot patio might be quoted at $3,200 by one contractor and $6,000 by another. The gap reflects real differences in what’s included: sub-base depth, reinforcement, drainage design, and whether the contractor accounts for Cobb County’s clay soil conditions in their prep work. A quote that skips proper sub-base preparation is cheaper at the start and expensive by year eight, when clay soil movement has cracked and settled the slab.
Marietta’s outdoor living culture means patios get significant use — from the swim-tennis communities of East Cobb to the wooded lots in Chestnut Creek, homeowners want patios that hold up under Georgia’s heavy rainfall (~50 inches per year) and occasional freeze cycles. Understanding what goes into the price helps you invest correctly rather than paying twice.

Types of Concrete Patio Finishes Available in Marietta
Broom finish is the baseline — textured surface for traction, clean look, lowest cost. Practical for functional outdoor spaces in Historic Marietta and West Cobb neighborhoods.
Exposed aggregate creates a natural pebble-surface appearance by washing away the cement paste before it sets to reveal the aggregate beneath. Provides a non-slip surface and a decorative look at a modest premium.
Stamped concrete patios use pattern stamps and color hardener to replicate flagstone, slate, brick, or cobblestone. The most popular decorative option in Marietta’s East Cobb and Windsor Oaks communities, where property values support the premium. See our full stamped concrete patio ideas for Marietta homes for design inspiration and detailed cost comparisons.
Stained or colored concrete applies acid stain or integral color pigment for a rich, uniform look. The decorative surface requires periodic resealing to maintain color in Georgia’s UV-intense climate.
Practical Uses: Cost Factors for Marietta Concrete Patios
-
Patio size: The primary driver. A 200-square-foot patio for a small outdoor seating area costs $1,600–$2,400 for plain concrete. A 600-square-foot entertaining patio runs $4,800–$12,000+ depending on finish.
-
Existing hardscape removal: Removing an old deck, paver patio, or slab adds $1–$2 per square foot. Many Marietta homeowners are replacing aging wood decks built in the 1980s and 1990s, which adds demo cost to the project.
-
Site grading for drainage: Marietta lots on rolling terrain — common near Kennesaw Mountain and in the Chestnut Creek area — require precise grading to ensure the patio slopes away from the foundation at the correct rate. Challenging grades add forming cost and sometimes retaining work.
-
Sub-base requirements: Georgia red clay requires a 4–6 inch compacted gravel base beneath the slab. This is non-negotiable for long-term performance in Cobb County — shortcuts here are the primary cause of patio cracking within 5–10 years.
-
Decorative finish type: Moving from plain to stamped adds $6–$12 per square foot. Multi-color or complex border designs add further cost for crew time and materials.
-
Permits: Concrete patios require permits in Marietta. City-limit and unincorporated Cobb County properties go through separate permitting authorities — see our concrete permit guide for Marietta for the full process.
How Marietta’s Rainfall Affects Patio Design and Cost
Marietta’s ~50 inches of annual rainfall — distributed heavily across spring and summer thunderstorm season — means concrete patios need drainage designed in from the start. The soil interaction framing here: Georgia red clay has low permeability, meaning water that falls on the patio surface drains slowly into the surrounding ground and tends to pool near the slab edge if the patio isn’t graded correctly. That pooled water migrates under the slab, saturates the clay sub-base, and — when the clay eventually dries — leaves voids that allow the patio to crack and settle.
Good drainage design adds modest cost upfront (primarily in grading labor and forming precision) but prevents the progressive damage cycle that shortens patio lifespan on Cobb County’s clay soils. Marietta Concrete Works includes drainage design review in every patio estimate — slope direction, downspout clearance, and perimeter drainage options are part of the site assessment, not an afterthought.
Frequently Asked Questions About Concrete Patio Cost in Marietta
Is a concrete patio cheaper than pavers in Marietta?
For initial installation, concrete is typically $4–$8 per square foot less expensive than concrete pavers and $6–$12 per square foot less than natural stone pavers of similar quality. Over a 15–20 year period, concrete’s advantage grows further because pavers require periodic re-leveling on Marietta’s clay soil as individual units shift with soil movement. Our concrete vs. asphalt vs. pavers guide for Marietta covers the full cost-of-ownership comparison.
How long does a concrete patio last in Marietta GA?
A properly installed concrete patio in Marietta typically lasts 25–40 years. The key variables are sub-base preparation for red clay, drainage slope design, control joint placement, and regular sealing every 3–5 years. Patios installed without adequate drainage design on Marietta’s clay soils tend to crack and settle in 8–15 years, particularly after several seasons of the wet-dry cycle that characterizes Cobb County’s climate.
When should I schedule my concrete patio installation?
Fall is the optimal time for concrete patios in Marietta — mild temperatures, lower humidity than summer, and you’ll have the space ready for spring outdoor season. Spring (March–May) is a strong second choice. Read our full guide on the best time to pour concrete in Marietta for seasonal scheduling details.
