What Does a Concrete Contractor in Marietta Actually Do?
A concrete contractor handles the full scope of concrete work: driveways, patios, walkways, slabs, foundations, and decorative finishes like stamped or exposed aggregate. Learn more about concrete driveway pricing in Marietta. Here in Marietta and the surrounding areas, most homeowners call for driveway replacement or patio installation, but the skill set spans both residential and commercial projects.
The key distinction: a concrete-only contractor specializes in flatwork and structural pours, while a general contractor may subcontract concrete to a specialist. (Ga.gov) For your project, you want someone whose primary expertise is concrete - they understand Cobb County soil conditions, local permit rules, and the specific challenges of our Georgia clay.
Common projects include:
- Driveways (most frequent request)
- Patios and decorative finishes
- Garage slabs and foundation pours
- Sidewalks and ADA-compliant walkways
- Retaining walls and curbs
When you call a contractor, they should ask about your project scope, site conditions, and finish preference before quoting. If they give a price over the phone without seeing the site, that's a warning sign.
How Much Does Hiring a Concrete Contractor in Marietta Cost?
Concrete pricing in Marietta runs $6–$15 per square foot installed in 2026, depending on project type, site prep, and finish. Here's what you can realistically expect:
| Project Type | Sq Ft Range | Cost Per Sq Ft | Typical Total |
|---|---|---|---|
| Standard broom-finish driveway | 400–600 | $8–$10 | $3,200–$6,000 |
| Stamped patio | 200–400 | $12–$18 | $2,400–$7,200 |
| Concrete walkway (4 ft wide) | 100–300 | $8–$12 | $800–$3,600 |
| Garage slab (20×20 ft) | 400 | $8–$12 | $3,200–$4,800 |
| Exposed aggregate finish | 300–500 | $14–$22 | $4,200–$11,000 |
Real example: A 500 sq ft broom-finish driveway at $8/sq ft = $4,000 installed in Marietta. That includes site prep (removal of old concrete if needed), 4–6 inches of compacted gravel base, concrete pour, finishing, and basic cleanup.
What affects your price:
- Thickness (4 inches standard for driveways; 3 inches for patios)
- Finish type (broom finish is cheapest; stamped or stained costs more)
- Site prep (removing old concrete, grading, compacting base)
- Slope and drainage (proper slope adds labor)
- Reinforcement (wire mesh or rebar increases cost)
- Concrete mix (higher PSI for heavy-traffic areas costs more)
Marietta's red clay soil requires a solid gravel base - typically 4–6 inches of compacted stone - to prevent heaving and cracking. A contractor who skips this step will save money upfront but create problems later. That base prep is non-negotiable here.
How Do You Vet a Concrete Contractor in Marietta, GA?
Vetting a contractor is the most important step. Learn more about Best Concrete Repair Contractors in Atlanta (2026). Learn more about how to vet a driveway contractor nearby. Here's the checklist:
1. Verify Georgia Licensing
Any contractor bidding work over $2,500 must hold a current Georgia contractor's license. Search the contractor's name or license number at the Georgia Secretary of State's Professional Licensing Boards portal. An active license means they've passed background checks and meet state standards.
2. Confirm Insurance
Ask for a Certificate of Insurance showing:
- General liability coverage (minimum $300,000–$500,000)
- Workers' compensation (required if they employ 3+ workers)
Request they name you as an additional insured. If they can't provide proof, walk away - you're liable if someone gets hurt on your property.
3. Check Cobb County Permit Compliance
Call Cobb County Community Development at 770-528-2000 to confirm whether your project needs a permit in Marietta. Retaining walls over 30 inches in height require a permit in Marietta; most residential flatwork under 30 inches from grade does not. A qualified contractor will know this and handle permits if required. Unpermitted work can create title and insurance issues later.
4. Review References and Online Ratings
Ask for at least three recent project references. Call them and ask:
- Did the contractor finish on time?
- Did they stay within budget?
- How was communication?
- Any issues after completion?
Check Google reviews and the Better Business Bureau for patterns. One bad review is normal; multiple complaints about the same issue (poor drainage, cracking, no follow-up) is a red flag.
5. Get Written Estimates
Obtain at least three written estimates. They should include:
- Project scope (what's being removed, replaced, or installed)
- Concrete mix design (PSI specification)
- Thickness and reinforcement type
- Sub-base depth and material
- Finish type
- Payment schedule
- Timeline
- Warranty terms
If an estimate is vague ("concrete work - $3,500"), ask for details. A professional contractor will provide a detailed breakdown.
What Should You Ask Before Signing a Concrete Contract in Marietta?
Before you sign, ask these seven questions:
1. What's your payment schedule? Standard is 30% deposit, 30% at pour, 30% at completion, with 10% held as retainage. Never pay more than 30% upfront. Avoid any contractor demanding full payment before work starts or cash-only deals.
2. Learn more about Best Concrete Driveway Installation Alpharetta (2026). Learn more about common concrete cracking issues in Marietta. What warranty do you provide? Expect at minimum a one-year labor warranty covering workmanship defects like premature cracking or surface delamination. Ask what cracks are covered (structural vs. hairline) and what isn't.
3. How long until I can drive on it? Concrete needs at least 7 days before vehicle traffic. Pedestrian traffic may be okay after 24–48 hours, but full cure takes 28 days. If a contractor says you can drive on it sooner, they're cutting corners.
4. What happens if it rains during the pour? Weather delays are common. A good contractor has a contingency plan and will reschedule rather than pour in heavy rain. Get this in writing.
5. Will you pull permits if required? If your project needs a Cobb County permit, the contractor should handle it. Don't hire someone who says "we'll skip the permit to save money" - that's illegal and exposes you to liability.
6. What's included in cleanup? Confirm whether they remove old concrete, haul debris, and clean the site. Some contractors charge extra for removal; others include it.
7. Do you have references from Marietta-area projects? Local references matter. A contractor familiar with our clay soil and seasonal weather patterns will do better work than someone from out of state.
Red flags to watch for:
- Cash-only payment demands
- No written contract
- Pressure to start the same day
- Refusing to provide license or insurance proof
- Estimates significantly lower than others (often indicates substandard materials or unlicensed work)
- Door-to-door "leftover materials" pitches after storms
How Do Concrete Finishes and Project Types Affect Who You Hire?
Not all concrete contractors are equally skilled at every finish type. Learn more about decorative concrete finish costs. Here's why it matters:
Broom finish (most common) is straightforward - a broom texture applied to wet concrete for slip resistance. Most general concrete crews can handle this.
Stamped concrete requires specialized timing and technique. The contractor must apply a retarder to slow the concrete's set, then press patterns into the surface at exactly the right moment. Too early and the concrete is too soft; too late and it won't take the pattern. A crew without specific stamped experience will botch the job.
Exposed aggregate is even more demanding. The contractor applies a retarder, then washes the surface to expose the stones. Timing is critical - wash too early and you damage the concrete; too late and the retarder has set. This is not a general crew job.
Decorative finishes command a premium because they require specialized skill. Expect to pay $8–$20 more per square foot for stamped or exposed aggregate versus plain broom finish.
When hiring for decorative work, ask to see a portfolio of completed projects on Houzz's Atlanta stamped concrete listings - not just photos, but ideally a site visit to see how the finish has held up over time. Ask how long they've been doing decorative work and whether they've completed projects in Marietta's climate.
Marietta's clay soil and seasonal moisture swings can cause issues if the base prep isn't perfect. A contractor experienced in our area knows this and will spec a proper gravel base and drainage slope. That's the difference between a driveway that lasts 20 years and one that cracks in five.
Finding a Qualified Concrete Contractor in Marietta
When you're ready to hire, start with at least three quotes from Marietta concrete contractors. Request quotes from at least three professionals who are in good standing and have great customer reviews. Here's where to look:

FAQ: Hiring a Concrete Contractor in Marietta, GA
How much does a concrete contractor charge per square foot in Marietta, GA?
Direct Answer: Standard concrete in Marietta runs $6–$15 per square foot installed in 2026. Learn more about Why Is My Concrete Slab Heaving in Conyers? (2026). Learn more about get a concrete installer estimate nearby. Stamped or decorative finishes cost $12–$22 per square foot.
The exact price depends on site prep, finish type, concrete mix strength, and local labor costs. A 500 sq ft driveway at $8/sq ft totals $4,000. Always get written estimates from at least three contractors to compare pricing and scope.
Does a concrete contractor in Georgia need to be licensed?
Direct Answer: Yes. Any contractor performing work valued at $2,500 or more must hold a current Georgia contractor's license.
Verify the license at sos.ga.gov by searching the contractor's name or license number. An active license confirms they've met state requirements. For smaller projects under $2,500, licensing is not legally required, but hiring a licensed contractor is still recommended for credibility and insurance purposes.
How long does a concrete driveway or patio project take in Marietta?
Direct Answer: Most projects take 1–3 days from start to finish, depending on size and weather. You cannot drive on the concrete for at least 7 days after the pour.
A typical 500 sq ft driveway takes one day to demo and prep, one day to pour and finish, then 7 days cure time before vehicle traffic. Spring and fall are ideal seasons in Marietta - temperatures between 50–85°F are optimal for concrete curing. Summer heat and winter cold can complicate the process.
What is the difference between a concrete contractor and a masonry contractor?
Direct Answer: A concrete contractor specializes in flatwork (driveways, patios, slabs) and structural pours. A masonry contractor works with brick, stone, and mortar - typically for walls, chimneys, and decorative brickwork.
For a driveway or patio, hire a concrete contractor. For a brick wall or stone veneer, hire a mason. Some contractors do both, but their primary expertise matters. Ask what percentage of their work is concrete versus masonry.
How many quotes should you get before hiring a concrete contractor?
Direct Answer: Get at least three written estimates before deciding.
Three quotes help you identify outliers - both unusually low bids (which often indicate substandard materials or unlicensed work) and unusually high ones. Compare the scope, materials, timeline, and warranty terms, not just price. The cheapest quote isn't always the best value.
What warranties should a Marietta concrete contractor provide?
Direct Answer: Expect at minimum a one-year labor warranty covering workmanship defects like premature cracking or surface delamination.
Ask the contractor specifically what types of cracking are covered (structural cracks versus hairline cracks) and what isn't. Material warranties depend on the sealer manufacturer and are typically separate from labor warranties. Get warranty terms in writing as part of your contract.
