Finished concrete typically costs $6-$15 per square foot when the price includes a standard poured slab, basic surface finishing, and installation; decorative finishes can raise the rate to $12-$30 or more. The final estimate depends on slab thickness, site preparation, finish type, access, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed concrete with basic finish | $6/sq ft | $10/sq ft | $15/sq ft | Typical 4-inch slab with ordinary access |
| Labor to finish fresh concrete | $1/sq ft | $2.50/sq ft | $5/sq ft | Finishing only; excludes concrete and placement |
| Decorative finished concrete | $12/sq ft | $20/sq ft | $30+/sq ft | Color, stamping, or specialty texture |
| 400-sq-ft basic patio | $2,400 | $4,000 | $6,000 | Before unusual excavation or demolition |
What finished concrete costs for a typical slab
For a new driveway, patio, or utility slab, a common installed price is $6-$15 per square foot. A straightforward 4-inch slab with a broom or smooth trowel finish often lands near $8-$12 per square foot. Small projects may have a minimum charge that pushes the effective rate higher, while large, accessible pours may cost less per square foot.
Finishing-only work is a different scope: labor to screed, float, edge, and texture concrete after placement may run $1-$5 per square foot. This rate generally does not include the concrete mix, forming, delivery, reinforcement, or base preparation. Assumptions: standard residential concrete, typical U.S. labor, normal access, and no major grading or removal.
For budgeting, use $10 per square foot for a standard installed slab, then adjust for site and finish details.
How concrete, labor, and finishing shape the quote
A contractor’s quote may combine several tasks into one installed rate. Ask whether the price includes excavation, compacted base, forms, reinforcement, concrete delivery, placement, finishing, and cleanup. The table shows typical component ranges; exact shares vary with project size, mix prices, and local crew rates.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| Concrete material | $2-$4 per sq ft | Thickness, mix strength, and order size |
| Labor and placement | $2-$5 per sq ft | Crew size, access, and pour complexity |
| Surface finishing | $1-$5 per sq ft | Broom, smooth, exposed aggregate, or stamped work |
| Base, forms, and reinforcement | $1-$4 per sq ft | Subgrade condition and steel or fiber requirements |
| Delivery, removal, and disposal | $150-$1,000+ per job | Truck distance, old slab removal, and debris volume |
Concrete is often ordered by the cubic yard, so thickness affects material use. A 4-inch slab needs about 0.012 cubic yard per square foot before waste; a 6-inch slab uses about 0.019 cubic yard. Labor is commonly estimated from crew hours and hourly rates.
Compare written scope line by line, because a low square-foot price may exclude base work or disposal.
How thickness and finish type change the square-foot rate
Thickness and surface treatment can move an estimate substantially. A 4-inch residential patio is a common baseline, while a 6-inch driveway or area expected to carry heavier vehicles needs more concrete and may need stronger reinforcement. Increasing thickness from 4 to 6 inches can add roughly $1-$3 per square foot, depending on mix and labor.
A basic broom finish typically stays near the standard installed range. Smooth troweling may cost similarly indoors, but polished concrete is a separate process and can run about $3-$12 per square foot for polishing after the slab is placed. Integral color may add $2-$5 per square foot; stamped patterns often add $6-$15 per square foot beyond a basic finish. Get the finish and slab thickness stated explicitly in the estimate.
What a 400-square-foot patio quote can include
A 400-square-foot patio with a 4-inch slab and broom finish may total $3,200-$4,800, or about $8-$12 per square foot, when the ground is mostly level and access is straightforward. A contractor might include forms, a compacted gravel base, welded wire mesh or fiber, a standard-strength mix, placement, broom finishing, and basic cleanup.
A more involved version with excavation, drainage adjustments, a colored or stamped surface, and old patio removal could reach $6,000-$10,000. For example, a 400-square-foot stamped patio at $18-$25 per square foot costs $7,200-$10,000 before major demolition or landscaping repairs. Use a project example only after matching its preparation and finish scope to the property.
How long concrete finishing takes and what labor costs
A small, accessible slab may take a crew of three to five workers about 6-10 hours for forming, placing, and finishing, with preparation completed earlier. Larger pours can require a full crew for 1-2 days, especially when the surface needs multiple finish treatments or the truck cannot discharge close to the forms.
Concrete finishers may bill at roughly $50-$100 per worker-hour, though many contractors price the project as a whole. A delay between delivery and finishing, a distant wheelbarrow route, or a hot, windy day that speeds curing can require more labor or equipment. Confirm whether the quote includes the crew needed to place and finish the pour within the concrete’s workable time.
When sealing, coloring, or stamping adds to the bill
Sealer may cost about $0.50-$2 per square foot, depending on product and surface preparation. It can be optional for a basic exterior slab, but it may be specified for decorative work or surfaces exposed to staining. Integral color is mixed into the concrete; surface stains and dyes are applied later and may have different prep and sealing costs.
Stamped concrete requires mats, detailed placement, and careful coloring, so it commonly costs $12-$30 per square foot installed. Exposed aggregate can run about $9-$18 per square foot. These ranges reflect finish complexity, not just material upgrades; patterns with borders, multiple colors, or tight corners add labor. Choose upgrades by comparing their installed price with the maintenance and appearance requirements of the space.
How regional labor and access affect delivered prices
Concrete prices vary with labor markets, ready-mix availability, fuel, and seasonal demand. Dense metro areas may run 10%-25% above a rural or lower-cost market, while remote sites can also cost more because of travel and delivery charges. Differences are local rather than fixed regional rules, so nearby contractor quotes are the best benchmark.
Truck access matters: a pump truck may add about $500-$1,500 or more, depending on distance, setup, and minimum fees. Difficult backyard access, steep slopes, long hose or wheelbarrow routes, and limited staging space can add labor. Ask whether delivery, pumping, and travel are included as fixed charges or billed separately.
Where homeowners can trim a concrete finishing estimate
Keep the slab dimensions and finish simple, and avoid decorative borders or multiple colors unless they are important to the design. Combining nearby concrete work into one pour may reduce minimum delivery and crew charges. Clearing access, moving planters, and arranging site access before the crew arrives can limit avoidable labor time, but excavation and base compaction should remain part of the scope when needed.
Request at least three itemized quotes using the same square footage, thickness, reinforcement, base depth, finish, and removal requirements. Compare the total price as well as exclusions, payment schedule, curing instructions, and warranty terms. Do not reduce required thickness or skip site preparation just to match a lower quote. The safest savings come from controlling finish complexity and comparing equivalent scopes, not cutting structural work.
