What to know about concrete patios in Seattle

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.

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.

Fire pit and seating areas

Round or curved areas with a seat wall or a hardscape edge.

Patios with steps

Stepped patios on a slope, often tied to a retaining wall.

Side yards

Narrow concrete paths and pads for trash bins, heat pumps or storage.

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

How Seattle’s ground and weather affect concrete patios

Threshold and steps

We check the door height first so the patio sits below it with proper steps, not tight against the siding.

Slope away from the house

Patios fall away from the house, typically about a quarter inch per foot, toward lawn, beds or a drain.

Downspouts

Roof water is the most common patio problem. We plan where downspouts discharge before the pour.

Moss and shade

North-facing and tree-shaded patios grow moss. Texture and sealer choice matter more here than in sunnier places.

Base

Topsoil and soft spots come out and are replaced with compacted gravel.

Permits

Ground-level patios often don’t need a building permit, but adding or replacing 750 sq ft or more of paving in Seattle generally needs an SDCI grading permit.

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. We give a written quote after we understand the job.

What affects the price

These are the things that move a quote most, in roughly the order they matter.

Size

Small patios cost more per square foot.

Removal

Breaking out an old slab or deck adds labor and haul-away.

Access

Back yards reached through a side gate may need a pump.

Finish

Color, aggregate and stamping add cost over broom.

Steps and walls

Steps down to the patio and seat walls are priced separately.

Drainage

Drains and downspout lines add cost and save the slab.

What a good written quote should include

Whoever you hire, ask for these in writing. They’re what separate a slab that lasts from one that cracks in two winters.

Scope and size

The area, thickness and shape, so you can compare quotes on the same job.

Base and drainage

How deep the excavation goes, how much gravel, and where water goes.

Reinforcement and joints

Rebar or mesh, dowels into existing concrete, and joint spacing.

Finish and sealing

The finish, whether it’s sealed, and what upkeep to expect.

Removal and cleanup

Demolition, haul-away and site restoration.

Permits and schedule

Which permits apply, who pulls them, and cure time before use.

Concrete Patios: common questions

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.

Can an old patio be resurfaced?

If it’s structurally sound, an overlay can refresh the surface. Sunken or broken slabs usually need lifting or replacement.

Can a sunken patio be lifted?

Often, if it’s in one piece and the soil has stopped moving. See concrete repair & leveling.

Will a new patio match my driveway?

We can match finish and joint style. Exact color match with older concrete isn’t realistic.
