What Drives the Price of Concrete?
Every concrete project is different. Here's an honest breakdown of the factors that move the number.
Square Footage
Bigger projects cost more total but less per square foot. We have a ~400 sq ft minimum project size.
Largest single factor
Slab Thickness
Driveways typically need 4–6". Foundations and heavy-use slabs need 6"+. Thicker = more material = more cost.
+$1–$3 / sq ft per extra inch
Finish Type
Broomed is most affordable. Smooth costs slightly more. Stamped and exposed aggregate add the most.
+$2–$7 / sq ft for decorative
Tear-Out & Haul-Off
Removing existing concrete adds labor, equipment, and disposal fees.
+$2–$4 / sq ft
Site Access
Tight backyards, steep slopes, and long wheelbarrow distances mean more labor hours.
Varies by site
Reinforcement
Rebar grid is stronger but costs more than wire mesh. We recommend rebar for driveways.
+$1–$3 / sq ft for rebar
Grading & Drainage
If your site needs regrading for water runoff, that's additional excavation and labor.
Varies by site
Color & Sealer
Integral color, surface color hardener, and sealer quality all affect the final price.
+$2–$5 / sq ft
Pricing Questions, Answered
Why don't you give exact prices online?
Because every site is different. A driveway on flat ground with easy access costs less than one on a slope with a tight backyard. We'd rather give you an honest range now and a firm written number after seeing your property — no vague ballparks that change later.
Is concrete cheaper than pavers?
Poured concrete is typically less expensive than pavers for the same square footage — paver materials and labor-intensive installation add up. However, pavers are easier to repair individually. See our concrete vs pavers vs asphalt comparison for the full breakdown.
Do you offer payment plans?
We work with standard payment terms: typically a deposit to schedule, progress payment at pour, and final payment upon completion. We can discuss specific arrangements during your estimate.
What's the minimum project size?
Our minimum project is approximately 400 square feet. This is because the setup cost (forms, equipment, concrete delivery minimum) makes smaller projects impractical.
