What's Included in the Cost
A professional patio installation from a qualified contractor should include:
- Excavation and site grading with proper drainage slope
- 4 inches of compacted CA-6 gravel sub-base
- 4 inches of 4,000 PSI air-entrained concrete
- Wire mesh or fiber reinforcement
- Control joints at proper intervals

Factors That Increase Patio Cost
- Demolition of existing patio or slab adds $2–$4 per square foot
- Multi-level or stepped patios require additional forming and engineering
- Poor drainage requiring grading corrections or French drain installation
- Limited access for concrete trucks (pump truck adds $500–$1,500)
- Integrated features like fire pit pads, seating walls, or built-in planters
- Complex stamped patterns with multiple colors and custom borders

Concrete Patio vs Other Options
Compared to pavers ($15–$30/sq ft), natural stone ($20–$40/sq ft), and composite decking ($25–$50/sq ft), concrete is the most cost-effective patio material. Stamped concrete can replicate the appearance of stone or brick at a fraction of the cost, making it the most popular choice among our customers.
