The installed band per square foot is only half of a patio estimate. The other half is the site: wet or cold-climate soil calls for a deeper base that no published band prices separately, and removal and grading are billed on top. On a small patio those two lines can outweigh the paving.
One patio, five surfaces
| Surface | Per sq ft | 280 sq ft |
|---|---|---|
| Poured concrete | $6–$16 | $1,680–$4,480 |
| Stamped concrete | $9–$16.25 | $2,520–$4,550 |
| Concrete pavers | $10–$16 | $2,800–$4,480 |
| Brick pavers | $14–$20 | $3,920–$5,600 |
| Natural stone / flagstone | $16–$30 | $4,480–$8,400 |
Area × each surface's installed band from this page's dataset.
The bands overlap more than the surface names suggest. A poured slab at the top of its band costs the same $4,480 as concrete pavers at the top of theirs, so compare two quotes on what is in them, not on the material alone. Flagstone's low end starts where the other four's high ends sit.
Wet or cold soil: what changes and what does not
The extra 2 to 4 in of base ICPI Tech Spec 2 calls for on wet, weak or cold-climate soil is not a small change. On 280 sq ft it moves the gravel from 3.5 to 5.2–6.9 cubic yards, and the dig from 7.375 in (base, 1 in of sand and a 2.375 in paver) to 9.375–11.375 in. None of the installed bands is keyed to base depth, so the price above does not move. Ask whether a quote on poor soil includes the deeper base; a cheap quote that does not is digging shallower, not working cheaper.
Joint sand: the one inside cost that depends on the stone
A 50 lb bag of polymeric sand covers only 22–42 sq ft in the wide joints of flagstone, against 65–85 sq ft in narrow paver joints. At $22 a bag, 280 sq ft of pavers takes 4–5 bags ($88–$110); the same area of flagstone takes 7–13 bags ($154–$286). It sits inside the installed price either way, but it is a real line on a DIY materials list.
