Concrete costs about $6-$12 per square foot for a typical professionally poured, plain slab, with an average near $8.50 per square foot. The concrete square footage price changes with slab thickness, reinforcement, site preparation, finish, access, and local labor rates; decorative finishes and difficult excavation can push the total well above the basic range.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed plain concrete | $6/sq ft | $8.50/sq ft | $12/sq ft | Typical 4-inch slab with ordinary access and site conditions |
| Installed reinforced slab | $8/sq ft | $12/sq ft | $18/sq ft | Rebar or mesh, thicker sections, or more demanding use |
| Stamped or decorative finish | $10/sq ft | $16/sq ft | $25+/sq ft | Patterning, color, sealing, and finish complexity affect price |
| Concrete removal and replacement | $10/sq ft | $16/sq ft | $30+/sq ft | Includes demolition and disposal; access and base repairs can raise cost |
Concrete square footage price for a standard slab
A basic 4-inch concrete patio, shed pad, or small residential slab commonly costs $6-$12 per square foot installed. A straightforward 400-square-foot project therefore runs about $2,400-$4,800, with roughly $3,400 as a practical midpoint. The quote generally assumes a standard concrete mix, simple forms, light grading, a broom or smooth finish, and no major demolition.
For a clear, level site and plain finish, budget around $8-$10 per square foot before unusual site work. A small job may exceed the typical per-square-foot range because the contractor still has minimum mobilization, delivery, and crew costs. Larger pours can lower the unit price when the site is accessible and the design is uncomplicated.
Driveways often cost $8-$15 per square foot because they may need a stronger base, thicker concrete, reinforcement, and control joints. A 600-square-foot driveway at $10-$14 per square foot would total $6,000-$8,400. A decorative patio can cost $10-$25 or more per square foot, depending on stamping, color, edge details, and sealer.
Assumptions: U.S. residential project, standard ready-mix, ordinary access, and no major drainage correction or unusual permitting.
What concrete, labor, and site work add to the quote
Contractors price the complete installation, not just the concrete delivered to the site. A quote may include excavation, base gravel, forms, reinforcement, placement, finishing, joints, curing materials, and cleanup. Ask whether the per-square-foot figure covers all these tasks and whether taxes or disposal charges are separate.
| Quote component | Typical price | What changes the charge | Common billing basis |
|---|---|---|---|
| Ready-mix concrete | $125-$200 per cubic yard | Mix strength, local supply, short-load fees | Per cubic yard |
| Placement and finishing labor | $3-$8 per sq ft | Finish, crew size, pour complexity | Per sq ft or project |
| Excavation and base preparation | $1-$5 per sq ft | Soil, grading, hauling, base depth | Per sq ft or equipment hour |
| Reinforcement and forms | $1-$4 per sq ft | Rebar spacing, mesh, slab perimeter | Per sq ft or linear ft |
| Demolition and disposal | $2-$8 per sq ft | Existing slab thickness, access, dump fees | Per sq ft or load |
Ready-mix is often a smaller share of the total than labor and preparation. One cubic yard covers about 81 square feet at 4 inches thick before allowance for waste. A 400-square-foot slab at that thickness requires approximately 5 cubic yards; ordering may be higher to account for edges, uneven grade, and pour conditions.
Labor estimates vary by crew and market. For a simple pour, labor may represent roughly one-third to one-half of the installed quote. Illustrative labor math: 24-40 crew-hours at $50-$90 per worker-hour equals about $1,200-$3,600 before equipment and materials; crew pricing may not be itemized this way.
Compare the included work line by line, especially base preparation, reinforcement, and disposal. Two bids with the same total can describe different slab thicknesses or finishing standards, making the apparent lower price misleading.
How thickness, reinforcement, and access change slab pricing
Thickness is a major cost driver because thicker concrete uses more mix and may require additional reinforcement. A 4-inch slab is common for patios and light-use areas; a driveway carrying passenger vehicles often uses 4-6 inches, subject to soil, climate, and local design needs. Moving from 4 to 6 inches increases concrete volume by 50%, although the full installed quote usually rises by less than 50% because some labor and setup costs stay similar.
Reinforcement can add around $1-$4 per square foot, depending on whether the design uses welded wire mesh, rebar, fiber, or a combination. For example, rebar installed on a 12-inch grid generally costs more than light mesh. Reinforcement helps manage cracking but does not guarantee a crack-free slab; the base, joint layout, curing, and drainage also matter.
Site conditions can add several dollars per square foot. Removing roots, correcting a slope, excavating rock, pumping concrete to a backyard, or building retaining forms requires extra labor or equipment. A tight gate or long wheelbarrow route can slow placement and increase crew time. Concrete pump charges commonly add several hundred to more than $1,000, depending on the equipment and local minimum.
Finish also matters. A standard broom finish is usually among the least expensive. Exposed aggregate, integral color, stamped patterns, borders, and multiple colors can add approximately $2-$15 or more per square foot over a plain finish. Sealer may add about $0.50-$2 per square foot, depending on product and preparation.
Check the stated thickness and reinforcement plan before comparing bids. A price for a 4-inch patio cannot be directly compared with a 6-inch driveway designed for heavier loads.
Does regional labor make concrete cheaper in some states
Concrete prices vary by labor availability, ready-mix distance, fuel costs, season, and local permitting. As a broad budgeting adjustment, rural and lower-cost markets may run about 10%-20% below a national midpoint for uncomplicated work. High-cost coastal metros and areas with limited contractor availability can run 15%-35% above it.
These differences are not a state-by-state price list. A rural project far from a batch plant may incur a delivery surcharge, while a city job may face parking restrictions, traffic delays, or a concrete pump charge. In colder regions, short pouring seasons can tighten schedules; hot climates may require additional attention to placement and curing. Obtain local quotes that specify delivery and site constraints rather than relying only on a national average.
Permit requirements depend on municipality, project size, drainage changes, and whether the work affects a driveway apron or public right-of-way. A simple patio may not require a permit, while a driveway connection or substantial grading may. Where required, permit and inspection charges can range from roughly $50 to several hundred dollars, with engineering or drainage reviews costing more.
Use the national per-square-foot range as a starting point, then adjust for local access and delivery. A contractor’s minimum charge can matter more than the regional average for a small pad.
What three concrete project quotes can look like
These examples illustrate how scope changes the total. They assume ordinary residential conditions and are not fixed market prices. Each includes installation labor; removal is included only where noted.
| Project and specification | Area and unit rate | Estimated total | Scope notes |
|---|---|---|---|
| Plain backyard patio, 4-inch slab | 300 sq ft at $8-$11/sq ft | $2,400-$3,300 | Basic excavation, forms, broom finish, accessible yard |
| Passenger-car driveway, 5-inch slab | 600 sq ft at $10-$15/sq ft | $6,000-$9,000 | Prepared gravel base, reinforcement, joints, broom finish |
| Stamped patio replacing old concrete | 400 sq ft at $18-$30/sq ft | $7,200-$12,000 | Demolition, disposal, new slab, color or pattern, sealer |
A 300-square-foot patio could cost more if the contractor has a minimum charge or must haul excavated soil through a narrow access route. Conversely, a larger, uncomplicated pour may achieve a lower unit rate by spreading setup and delivery expenses across more square footage.
Ask for a written scope that states area, thickness, finish, reinforcement, base depth, and exclusions. Those details make the example prices useful for comparing actual estimates.
How many hours a residential concrete pour takes
Preparation often takes longer than the visible pour. A small, accessible patio may need one to three days for excavation, base work, and forms, followed by several hours for placement and finishing. A driveway can require two to five workdays depending on demolition, grading, reinforcement, and curing logistics. Weather, inspections, and contractor scheduling can extend the calendar time.
Concrete crews generally need to place and finish the mix promptly after delivery. A small job may use three to five workers, while larger pours may require additional finishers or equipment operators. If a crew must make multiple trips or order a short load, a supplier minimum can add roughly $100-$300 or more, depending on local terms and delivery volume.
Concrete may be walkable after about 24-48 hours under suitable conditions, but that does not mean it has reached full strength. Vehicle traffic is often delayed for at least seven days, and many mixes continue gaining strength for about 28 days. The contractor should give project-specific access instructions, especially in cold or hot weather.
Budget for preparation and curing time, not only the hours when concrete is being poured. Rushing access or scheduling around a delivery without finished forms can cause costly delays.
When resurfacing costs less than replacing concrete
Resurfacing can cost about $3-$10 per square foot when the existing slab is structurally sound and the work involves cleaning, patching, and applying an overlay. Decorative resurfacing may cost $7-$15 per square foot. It is generally unsuitable for slabs with major settlement, extensive structural cracking, severe drainage problems, or widespread movement.
Replacement commonly costs $8-$18 per square foot for removal and a new plain slab, and can exceed $30 per square foot when access, thick concrete, disposal, or decorative work is involved. A replacement quote should identify whether the contractor removes the old concrete, hauls it away, installs new base material, and addresses the cause of the original damage.
Crack repair is less expensive for isolated, stable cracks, often around $5-$15 per linear foot for basic filling, though repairs may remain visible. If a slab is uneven, a leveling method may cost approximately $3-$8 per square foot, but suitability depends on the concrete condition and the reason for settlement. These options do not replace a structural assessment when the slab is unsafe or continuing to move.
Resurfacing saves money only when the underlying slab is stable enough to support the new finish. Paying for a temporary overlay before replacing a failed base can increase the eventual project expense.
Which finish and preparation choices lower the concrete bill
Keeping the layout rectangular, using a standard broom finish, and avoiding multiple colors or intricate borders can reduce labor and material charges. A simple finish may save several dollars per square foot compared with stamped concrete. For a large patio, that difference can amount to hundreds or thousands of dollars, while a small decorative area can be retained as an accent without finishing the entire slab at premium rates.
Before work begins, clear movable items and confirm where equipment and concrete trucks can reach the site. Homeowners should not remove structural concrete or excavate near utilities without appropriate expertise and utility marking. A contractor can advise whether ordinary cleanup is included and whether site access changes the quote.
Compare at least three local written estimates with the same dimensions and specifications. Check whether each bid includes excavation depth, base material, reinforcement, control joints, curing, disposal, permit fees, and sales tax where applicable. Confirm the contractor’s schedule and payment terms, and ask how extra work is priced if soil conditions differ from expectations.
The most reliable savings come from simplifying the design while keeping the slab specification appropriate for its use. Reducing thickness or skipping base preparation just to lower the quote can lead to premature cracking, settlement, or replacement costs.
