Notes
- Where the number comes from. The national price for a poured concrete slab is $6.50 per ft² of slab — poured slab pricing published for 2026, $4–$11 per ft² for a 4-inch slab on grade. Labor is about 50% of that. Cement Masons and Concrete Finishers near Santa Ana, CA average $70,030 a year against a U.S. mean of $60,050 — a factor of 1.166 — so the labor half is scaled by that and the material half is not.

- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- What is in the price: excavation to grade, a compacted gravel base, forms, wire mesh or fibre, the concrete itself, placing, screeding, a broom or trowel finish, and labor.
- What is not: thickened edges for a load-bearing wall, a vapour barrier under a heated slab, rebar mats where an engineer calls for them, saw-cut control joints past the standard spacing, and any grading or drainage work around the pour. These are the lines that turn a $2,816 quote into a $3,520 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

Why the city changes the number
About 50% of this job is labor — $1,408 of the $2,816 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.
Cement Masons and Concrete Finishers near Santa Ana average $70,030 a year, against a U.S. mean of $60,050. That is a factor of 1.166, so the labor half is scaled by it and the material half is not.

What the quote should include
The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $2,816 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $1,733 – $4,766, that is not automatically wrong — but it is the question worth asking out loud.
