Stamped concrete cost in Seattle, WA

How Seattle compares

Contractors rarely work more than an hour or two from home, so the neighboring metros set a rough ceiling and floor for your quotes. Midpoints for 400 sq ft range from $6,450 to $6,800 across Seattle and its five closest metros.

Across 300 US metros, Seattle comes in at #7 from the top. The priciest is Kahului, HI at $8,150; the cheapest is McAllen, TX at $4,550 (midpoints, 400 sq ft). Statewide, Seattle is 3% above the Washington figure.

Planning more than one job in Seattle?

Because every project leans on different trades, Seattle's wage level does not move all prices equally. Against the US midpoint, concrete driveway runs +27% and concrete slab +18%.

Specs and site conditions that change a Seattle bid

• Sealing and vapor barrier

  Sealer is usually quoted separately; vapor barrier material is $0.20-$1.50 per sq ft depending on thickness (HomeGuide).

• Not included

  These prices don't include site prep that depends on the project: demolition, grading, or a thicker base.

• Pattern and color

  Basic to average coloring runs $8-$19 per sq ft. A 2-car stamped driveway runs $12-$18 per sq ft (HomeGuide); Estimators.us puts decorative slabs at $15-$30.

Pick a size, pick a tier: stamped concrete pricing in Seattle

Three bands are cut from the same cited range and localized for Seattle wages and prices. They overlap on purpose: a good standard job and a modest premium job can cost the same. The grid below prices the same bands at 3 common sizes.

Optional extras in Seattle

Extras are quoted nationally and then scaled to Seattle by the average of the local wage index (1.39) and goods index (1.04), a factor of 1.22. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.

When to schedule stamped concrete in Seattle

We use NOAA's 1991-2020 climate normals for Seattle Sand Pt Wsfo (5 miles from the city center). These are 30-year monthly averages, not forecasts.

April through November is the stretch where pouring concrete runs into the fewest weather problems in Seattle (8 of 12 months). January, February, March and December have an average overnight low of 40°F or below.

The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.

Seattle gets about 38 inches of precipitation in a normal year, including roughly 4 inches of snow. The wettest months are January, November and December (5.8 inches in November). Inside the workable window, July and August are the driest, at 0.8 and 1.0 inches. The station averages about 2 days a year at 90°F or above.

Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Local wages behind the labor line

Wages are the part of this estimate that changes most from town to town. 3 trades carry the job here, and each is compared with its US median. The weighted result for Seattle is 1.39 times the national level.

For cement masons and concrete finishers (47-2051, weighted 60%) the local median is $38.88 an hour, which is 42% above the national $27.41. The middle half of them earn between $29.14 and $52.52 an hour. BLS counts 2,140 of them working in the area, 10.3 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.

Construction laborers (47-2061), 30% of the weighting: a median of $28.72 an hour, 27% above the US median of $22.66. The middle half of them earn between $23.67 and $37.03 an hour. About 13,040 work in the metro. That is 62.5 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.

For operating engineers and other construction equipment operators (47-2073, weighted 10%) the local median is $46.04 an hour, which is 60% above the national $28.78. The middle half of them earn between $36.13 and $58.78 an hour. BLS counts 4,860 of them working in the area, 23.3 for every 10,000 jobs (US: 30.7), so the local bench is thinner than average.

Quotes come from real crews, not medians. If the cement masons and concrete finishers on your job are paid at the 75th percentile ($52.52 an hour) instead of the median, the labor line grows by about $810. At the 25th percentile ($29.14) it shrinks by about $580. The total moves by 11.9% or 8.5%, so wages alone rarely explain a quote that is far outside our range.

For context on the local economy, BLS counts 2,086,210 jobs in the Seattle-Tacoma-Bellevue area. That makes it the 13th largest of the 300 metros we cover, with 1.34% of US employment.
