Concrete patio cost in 2026: broom, stamped and exposed aggregate on three patio sizes
What a concrete patio or slab costs in broom finish, stamped and exposed aggregate on 10×20, 20×20 and 20×30 ft, what goes under the slab, and what a concrete quote should spell out.
Concrete is priced by the square foot, but two things decide the number: the finish on top and the work underneath. Here are three patio sizes in three finishes, and what a concrete quote should spell out.
What a concrete patio costs
| Type | 10 × 20 ft | 20 × 20 ft | 20 × 30 ft |
|---|---|---|---|
| Broom finish | $2,664 | $4,928 | $7,193 |
| Stamped or coloured | $3,671 | $6,941 | $10,212 |
| Exposed aggregate, reinforced | $4,928 | $9,457 | $13,985 |
Priced by the same engine our free quote tool uses, at its starter rates, with a 4-inch slab over a compacted base. Breaking out and hauling away an old slab is extra, and so is sealing.
The three finishes
- Broom finish: plain grey with a brushed texture for grip. The cheapest, the grippiest when wet, and it needs nothing afterwards.
- Stamped or coloured: pressed with a pattern and tinted to look like stone, brick or slate. Needs resealing every few years to keep its colour.
- Exposed aggregate: the top washed off to show the stones in the mix. Slip-resistant and hard-wearing; a favourite for pool decks.
What goes underneath decides how long it lasts
- Base: 4 inches or so of compacted gravel. On expansive clay, such as much of Central Texas, the base and drainage matter more than the finish.
- Thickness: 4 inches for a patio or walkway. Codes generally require at least 3½.
- Reinforcement: rebar or wire mesh holds cracks together when they come.
- Control joints every 8–10 feet, so the slab cracks where it is told to rather than across the middle.
What a concrete quote must spell out
- Square footage, thickness and finish
- Base depth and material, and how it is compacted
- Rebar or mesh, and joint spacing
- Tear-out and haul-away of anything existing
- Sealing, if any, and when
