Name

Concrete work in Seattle

Seattle concrete work is shaped by three things: hills, old houses, and rain. A lot of the city was built out before 1950, so many jobs start with breaking out a tired driveway, a heaved walk, or front steps that were poured decades ago. Lots are narrow, many have alleys, and street trees in the planting strip are everywhere.

We work across Ballard, Wallingford, Queen Anne, Magnolia, Capitol Hill, Beacon Hill, West Seattle, Rainier Valley, Lake City and Northgate.

What’s different about concrete in Seattle

Slopes and hills

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.

Soil and water

Soils change block to block: dense glacial till on many ridges, softer fill and old wetland soils in lower areas like parts of the Duwamish valley, Interbay and around the lakes. A slab that keeps sinking usually points to a soft or wet base. 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.

Sidewalks and right-of-way

In Seattle, the owner of the lot next to a sidewalk is generally responsible for keeping it in repair. Work in the sidewalk, planting strip, curb, or driveway apron is in the public right-of-way and goes through SDOT.

Trees

Mature street trees lift sidewalk panels and driveway aprons all over the older neighborhoods. Cutting roots is regulated; SDOT’s urban forestry staff get involved when a street tree is near the work.

Lots 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.

Homes we see

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.

Concrete in Seattle: common questions

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.

Who fixes the sidewalk in front of my house?

Under Seattle’s rules, the adjacent property owner is generally responsible for sidewalk upkeep. SDOT issues the permit for the repair, and the work has to meet City standards.

Can you work on steep or narrow Seattle lots?

Yes. Steep driveways, stepped yards, and tight side yards change how forms are set and how concrete gets to the pour, sometimes with a pump. We look at access before quoting.
