What changes the price of a patio
- Size: small patios cost more per sq ft because setup, delivery and finishing crew are the same; larger pours bring the per-foot price down.
- Access: a backyard reached only through a gate may need a concrete pump or buggies.
- Shape and steps: curves, circles and poured steps take more forming and finishing time.
- Extending an existing slab: tying into the small builder slab many new homes have is common and usually saves money over a full tear-out.
- Finish: broom finish is the most affordable; stamped patterns, multiple colors and borders cost more.
How to get more patio for your budget
- Pour a plain broom-finish slab with a stamped border — it gives a decorative look for much less than fully stamped.
- Keep the shape simple and add curves only where they matter, like the edge facing the yard.
- Build the patio now and plan the walkway or extension as a second phase.
