Price per square foot

Prices by finish, with the arithmetic showing.

Pick a finish, multiply by your square footage, add the lines that apply. That is honestly how we build a quote. The estimator below does it for you and prints every step.

Exposed aggregate concrete with thin saw-cut control joints crossing it
Exposed aggregate, $12 to $17 per sq ft. Saw-cut joints at 10 ft.

By finish

Price per square foot

2026 prices for flatwork in our service area, for a 4 in slab on our standard base. Ranges, not promises: the firm number comes after the site visit.

What the price includes

Every per-square-foot price includes

  • Site visit, layout with paint and string, and the permit where one is needed
  • Excavation of up to 6 in of soil and grading of the subbase
  • 6 in of compacted 21AA crushed gravel (4 in under walks)
  • Forms, expansion joint where the slab meets the house or garage
  • 4,000 psi air-entrained mix, fiber in the batch, wire mesh on chairs
  • Control joints cut or tooled the same day, a quarter of the slab deep
  • Curing compound sprayed after finishing, and the printed cure card
  • Forms pulled, edges backfilled with topsoil, site swept

Priced as its own line

  • Tearing out and hauling away old concrete (priced per square foot below)
  • Extra digging when we hit soft clay or old fill (we show you before we charge)
  • Steps, sealer on broom and aggregate finishes, a line pump
  • City right-of-way permit fees, passed through at cost

$2,400 Minimum job. One truck and one crew day cost the same for a small pad as for a big one.

Square-footage estimator

Run your numbers.

Every line of math prints on the right: area, cubic yards, trucks, the joint layout and each price line. It is an estimate, not a quote. Nothing you type here is sent anywhere.

Comparing bids

Why two bids can be $3,000 apart.

Lay the bids side by side and look for these four lines. If one bid does not mention them, call and ask. Then call us with the answers; we will tell you honestly if the cheaper one looks fine.

  • 01

    Base depth

    Two inches of gravel and six inches compacted in lifts are not the same job, and they are not the same price.

  • 02

    Steel

    Mesh on chairs, rebar, or nothing at all. Ask where the steel sits; mesh lying on the dirt does nothing.

  • 03

    Tear-out

    Some bids leave it out, then add it on the day. Ours is its own line, priced per square foot.

  • 04

    Access

    If the truck cannot reach the forms, someone pumps or wheels it. We price that up front as a line pump.
