Concrete Patios for Seattle properties
A good patio starts at the back door: the height of the threshold, how many steps down, which way the yard falls, and where rain off the roof ends up. Get those right and a plain broom-finished slab will last decades. Get them wrong and even the nicest stamped pattern ends up with puddles, moss and cracks.
Craftsman bungalows, Tudors, and mid-century houses with original concrete are common, alongside new townhomes and backyard cottages (DADUs) that need new slabs and walks. We work across Ballard, Wallingford, Queen Anne, Magnolia, Capitol Hill, Beacon Hill, West Seattle, Rainier Valley, Lake City and Northgate.
New patios
A level outdoor room where the lawn or an old deck used to be.
Replacing old slabs
Cracked, sunken or tipped patios that send water toward the house.
Covered patios
Slabs under a roof or pergola, with posts and footings planned in.
Seattle conditions that affect your patio
Yards and access
Back yards are often small, shaded, and reached through a narrow side yard or alley. Concrete sometimes has to be pumped or wheeled in, which affects the schedule and the price.
Rain and drainage
Long rainy seasons mean water management decides how long concrete lasts: slope away from the house, joints that drain, and somewhere for downspout water to go.
Slope and access
Queen Anne, Magnolia, West Seattle, Capitol Hill and the slopes above Lake Washington have steep driveways and stepped yards. Parts of the city are mapped as steep-slope or landslide-prone environmentally critical areas (ECAs), which brings extra SDCI review for grading and walls.
Details that help us price your patio in Seattle
You don’t need answers to all of these. They’re the questions that shape the design and the price.
Size and shape
Rough measurements or a sketch over a photo.
Door and steps
How far the door threshold is above the ground.
What’s there now
Lawn, old slab, pavers or a deck to remove.
Water
Where downspouts discharge and where the yard stays wet.
Access
Gate width and whether a truck can get near.
Finish and extras
Broom, aggregate, color or stamped; steps, seat walls or a fire pit.
Options to talk through
| Finish | Good for | Keep in mind |
|---|---|---|
| Broom | Everyday patios on a budget | Best traction; plain look |
| Exposed aggregate | Wet, shaded yards | Textured and grippy; hides dirt |
| Integral color | A warmer look than gray | Color runs through the slab |
| Stamped | A stone or slate look | Reseal every few years; choose slip-resistant sealer |
Permits for concrete patios in Seattle
In Seattle, adding or replacing 750 sq ft or more of paving generally needs an SDCI grading permit. Smaller patios and walks often don’t. Anything in the sidewalk, planting strip, curb or driveway apron is right-of-way work that needs an SDOT permit. Check SDCI’s permit guide for your address.

Typical market ranges, not a quote from Seattle Concrete Contractors. These are ranges other Seattle-area concrete contractors publish for this work (Seattle Concrete (seattleconcrete.com) service pages, checked November 2026). Your price depends on size, access, removal, base work, finish and permits, and on conditions at your Seattle property. We give a written quote after we understand the job.
Concrete Patios in Seattle: quick answers
How long does a new patio take?
Most patios take a few days of work: demolition and base, forming and pour, then curing time before furniture goes on it. Weather can stretch that.
Do I need a permit for a patio in Seattle?
A ground-level patio often doesn’t need a building permit. Adding or replacing 750 sq ft or more of paving generally needs an SDCI grading permit, and drainage rules can apply.
What’s the best patio finish for a wet yard?
Exposed aggregate or a broom finish gives the most grip. Stamped looks great but needs a slip-resistant sealer.
Do I need a permit for concrete work in Seattle?
It depends on the job. SDCI generally requires a grading permit when you add or replace 750 sq ft or more of paving, and walls taller than 4 ft measured from the bottom of the footing need a permit. Anything in the sidewalk, planting strip or driveway apron is right-of-way work that goes through SDOT.
