Concrete patios in Seattle typically run:
$12–$20 per square foot installed
Typical project ranges
- Small patio (200–400 sf): $4,000–$9,000
- Medium (400–700 sf): $7,000–$14,000
- Larger / custom: $12,000–$25,000+
What affects the price
1. Access
Backyards in Seattle are rarely easy. Limited access = more labor or pump truck.
2. Excavation + grading
If your yard isn’t level, expect extra cost for cut/fill and retaining edges.
3. Drainage (important here)
Patios need slope away from the house. Sometimes drains or gravel sub-base are required.
4. Finish options
- Standard broom: lowest cost
- Exposed aggregate: popular in Seattle, mid-range
- Stamped: highest cost, more maintenance
5. Edges, steps, seat walls
Anything beyond a flat slab adds up fast.
What most people miss
Drainage and base prep matter more than the finish. A cheap patio that holds water won’t last.
