The short answer
A four-inch, air-entrained, broom-finish concrete patio in Olathe costs about $8 to $13 per square foot in 2026 on a compacted base. A smooth troweled border adds $1 to $2 per square foot. Exposed aggregate runs $11 to $16. Stamped concrete runs $14 to $22 depending on pattern, color and border.
| Patio | Area | Broom finish | Stamped |
|---|---|---|---|
| Small, 10×12 | 120 sq ft | $1,200 – $1,800 | $1,900 – $2,800 |
| Dining, 12×16 | 192 sq ft | $1,600 – $2,500 | $2,700 – $4,200 |
| Standard, 16×20 | 320 sq ft | $2,600 – $4,200 | $4,500 – $7,000 |
| Large, 20×24 | 480 sq ft | $3,900 – $6,200 | $6,700 – $10,600 |
| Wraparound, 600 sq ft | 600 sq ft | $4,800 – $7,800 | $8,400 – $13,200 |
Small patios cost more per square foot than large ones because the truck, the crew and the setup cost the same either way; most of our patio jobs carry a minimum around $1,200.
The lines people forget
- Footings for a cover. A pergola or a patio cover sits on posts, and posts need footings below the frost line, not just the slab. Poured with the patio, $150 to $350 each. Cut into a finished patio later, a lot more.
- Drainage. A patio that catches a downspout will heave on the clay. Extending downspouts past the slab and moving sprinkler heads runs $150 to $700, and it's the best money on the job.
- Tear-out. Removing an old patio, $1.50 to $2.50 per square foot, hauled to a recycler.
- Steps. A step down from the back door or out to the yard, $250 to $500 per riser.
- Sealer. A penetrating sealer on broom or aggregate, $0.90 to $1.60 per square foot; stamped work needs a breathable decorative sealer, included in the stamped price, and resealing every two to three years at $1.50 to $3.
Concrete against pavers and decks
Paver patios in the Kansas City area run roughly $18 to $30 per square foot installed and can settle on clay unless the base is deep and well compacted; they can be lifted and relaid, which concrete can't. A wood deck runs $25 to $45 per square foot and needs staining; composite more. Concrete is the cheapest hard surface per foot and the lowest maintenance, and a stamped patio gets most of the look of pavers for less.
Permits and the HOA
A patio at grade on your lot doesn't appear on the City's residential permit list; a cover or pergola does need a permit, and a retaining wall does too. Most Olathe HOAs want to approve a patio that grows past the builder's slab or changes the look. We send the drawing and the finish sample before we schedule.
Common questions
Why does a small patio cost more per foot?
The truck, the crew and the forms cost about the same for 120 square feet as for 400. The minimum charge covers that; the per-foot price drops as the patio grows.
Should I pour the footings for a pergola now?
If a cover is at all likely, yes. Footings poured with the patio cost $150 to $350 each; cutting them into a finished slab later costs more and leaves patches.
Broom, aggregate or stamped?
Broom is cheapest and grips best. Exposed aggregate hides wear and grips wet. Stamped looks like stone and needs resealing every few years. All three last if the base and the mix are right.
Do I need a permit for a patio?
Not for the slab at grade in most cases. A cover, a pergola or a retaining wall does need one. We confirm with the City when a job is unusual.
Will it crack?
All concrete cracks. Joints at the right spacing, a compacted base, isolation from the house and water kept off the edges put the cracks where you can't see them.
