The cost to build a patio in Seattle ranges from $1,820 to $9,700, with most homeowners paying around $4,240. Your actual cost depends on several factors specific to your home and the Seattle-Tacoma market.
Patios are priced per square foot — larger patios cost more but have lower per-square-foot rates due to efficiency of scale.
Poured concrete is cheapest ($8–$15/sq ft), pavers cost $12–$25/sq ft, and natural flagstone runs $15–$35/sq ft installed.
Proper excavation, grading, and gravel base are essential for a level, durable patio. Poor base prep leads to settling and cracking.
The patio must slope away from the house (1/4 inch per foot minimum) — regrading or adding drainage can add 10–20% to the project.
Simple running-bond or straight patterns are fastest. Herringbone, basket weave, and circular patterns add 20–40% more labor time.
The Pacific Northwest has moderate to high labor costs. Rain affects exterior scheduling October through April. Green building practices are common and many contractors specialize in energy-efficient work.
Patio construction in Seattle generally does not require a permit for standard installations. Check with your local building department if your project involves panel work or structural changes.
Year-round construction seasons give you the most flexibility for exterior projects. Take advantage by scheduling during slower months for potentially better rates.
Handy homeowners with basic tools can handle straightforward patio construction. If your project involves the panel, new circuits, or gas lines, hire a licensed pro. DIY can save $1,631–$2,097 in labor.

Most patio construction projects in Seattle take 2–5 days to complete. The timeline depends on project scope, contractor availability in the Seattle-Tacoma metro area, and seasonal demand. Scheduling during Seattle's off-peak season (typically winter months) can reduce wait times and may lower costs.
Patios are typically 30–50% cheaper than decks. A poured concrete patio costs $8–$15/sq ft vs $15–$25/sq ft for a basic wood deck. Patios also require less maintenance. However, decks work better on sloped terrain or when you want an elevated outdoor space.
Properly installed paver patios last 25–50+ years. Individual pavers that crack or settle can be easily replaced without redoing the entire patio. The key to longevity is proper base preparation — 4–6 inches of compacted gravel and 1 inch of leveling sand.
