Concrete Patio Installation in Seattle
Concrete patios are the highest-leverage backyard investment in Seattle: a properly built patio adds measurable home value, lasts 30–50 years, and handles year-round Pacific Northwest weather better than wood, composite, or loose-set pavers. We install new patios, replace heaved or cracked ones, and level settled slabs across King, Snohomish, and Pierce counties. Stamped, exposed-aggregate, broom, and integral-color finishes are all part of the scope; the right one depends on use, sun exposure, and how water moves off the surface.
Patios for indoor-outdoor living
A well-designed patio extends your usable living space and adds measurable property value. We plan layout to connect naturally with interior floors, doors, and grade, and size the slab so furniture and traffic flow comfortably. Many Seattle homeowners pair a patio with a covered pergola or roof extension - we coordinate the slab edge and anchor bolt placement upfront so structural additions go in without retrofitting.
Patio leveling and repair
Uneven or settled patios create trip hazards and collect standing water - common in Seattle's clay-heavy soils. Our team evaluates whether lifting and leveling, resurfacing, or slab replacement is the right call. See our patio leveling guide for a detailed comparison of options and costs.
Patio installation process
We plan layout and elevation, prepare the base with compacted gravel, set forms, place rebar or mesh, and finish the surface with a minimum ¼-inch-per-foot slope for positive drainage. Most residential patios are poured and finished in one or two days; the slab needs 7–28 days to cure before full furniture loads or foot traffic.
Materials and finishes
We offer broom, exposed aggregate, integral color, and stamped finishes. In Seattle's wet climate, broom finish offers the best year-round traction. Stamped and stained patios look great but require a non-slip sealer applied every 2–3 years to stay safe when wet.
Typical patio projects
Common work includes new patio pours for backyard living areas, patio expansions, integrated walkway connections, step additions, and surface overlays on structurally sound slabs that need a cosmetic refresh.
Seattle patio design considerations
Seattle's rainfall means patio drainage is non-negotiable. We slope slabs away from the foundation and house walls, and can integrate channel drains at the perimeter when grade or fencing limits runoff direction. For hillside lots - common in neighborhoods like Capitol Hill, Ballard, and Beacon Hill - we account for retaining edges and lateral drainage in the design before the first shovel goes in. If your project includes a hot tub, outdoor kitchen, or fire pit, we size the slab thickness and reinforcement accordingly.
Patio cost in Seattle by finish type
| Finish | Installed cost (per sq ft) | Notes |
|---|---|---|
| Broom finish | $6–$10 | Best traction; most common residential choice |
| Exposed aggregate | $10–$16 | Textured; excellent in wet conditions |
| Integral color | $8–$14 | Color throughout slab; consistent as surface wears |
| Stamped concrete | $12–$20 | Mimics stone or tile; resealing every 2–3 years required |
Cost varies with slab area, base prep, access, and whether existing concrete is removed. We provide a firm estimate after an on-site visit.
Frequently asked questions
How much does a concrete patio cost in Seattle?
Pricing depends on square footage, finish, base prep, and access. Stamped or stained finishes cost more than a standard broom finish. We confirm with an on-site estimate.
How long does it take to install a concrete patio?
Most residential patios are installed over 2–4 working days, plus 7–28 days of curing depending on use and weather.
Do I need a permit for a backyard concrete patio in Seattle?
Most ground-level residential patios on private property don't require a permit, but covered patios, raised patios, or work near drainage may. We confirm requirements before starting.
What's the best concrete patio finish for Seattle's wet climate?
Broom finish provides the best traction when wet. Stamped finishes can be slick — we recommend a non-slip sealer when stamped or stained finishes are used.
Can you resurface an existing concrete patio?
Yes, when the existing slab is structurally sound. We grind, repair, and apply an overlay or stain. If the slab is heaving or badly cracked, replacement is usually more cost-effective.
