Most calls start with a backyard that's bare dirt, worn pavers or an old slab that has cracked and sunk. A patio is flatwork, the same kind of ground-level slab as a driveway or a walk. The timing between placing, finishing, cutting joints and curing matters more than people expect, because concrete gives you a short window to finish it while it's still workable.
The price moves mostly with the size of the patio, the finish you pick, whether old concrete has to come out first, and anything extra that goes in before the pour, like steel for an outdoor kitchen. I write all of that into the estimate, which lists what's included, such as taking out the old slab and cleaning up afterward, so you see your own figure before we start.
The schedule turns on three things: whether your job needs a permit, the weather on pour day and the curing wait before you can use the patio. Before we set a date, we confirm whether your address falls under the city or the county, since that decides which office we go to about a permit.
