How Much Does a Concrete Patio Cost in Seattle?

Local Market

Seattle pays some of the highest wages in the country. The loaded labor rate for concrete work hits $58.39 per hour once you add the 40.06 percent burden on top of the $41.69 base BLS wage (TheFatBook cost index, 2026). That single input pushes the city average for a concrete patio to $4,355 which sits 16.9 percent above the national figure of $3,726. Median household income lands at $116,068 yet the median home value reaches $938,600. The resulting 7.6 times price to income ratio means even upper middle earners feel squeezed. Tech sector cooling has unemployment at 4.5 percent in the metro area. That's elevated for this market and it may finally give contractors a bit more breathing room on scheduling. The cost to deliver a standard 400 square foot concrete patio comes in at $3,529 before any margin according to the model. Materials alone eat $1,503 after FRED PPI adjustments. Overhead allocation adds another $829 from NAHB benchmarks. Those inputs explain why bids here rarely feel cheap. Rain from October through May shortens the workable window for concrete work so crews stay busy when the sun appears. The data shows why your neighbor's patio quote looked high but probably wasn't pure gouging.

Understanding Your Bid

An 18.9 percent contractor margin on the average $4,355 bid means the spread between what it costs to deliver and what homeowners pay sits at roughly $829 (TheFatBook cost index, 2026). That's real money. The lowest realistic price of $3,888 leaves $467 of potential savings between the average and the floor. Not every bid at $4,600 is automatically a rip off. Some contractors simply carry higher overhead or schedule their crews with more buffer. But when you see $4,857 on the high end you have to wonder where the extra labor hours or markup landed. The cost index uses 20.5 Craftsman hours at the local loaded rate of $58.39. Materials track at $1,503. Permit line stays at zero for this scope yet local taxes can still appear. Run the numbers yourself. The cost to deliver lands at $3,529. Everything above that's margin. The floor at $3,888 represents the bottom of the sustainable fair band for this market not the bare bones expense. If your bid comes in well above that average you now know the gap is larger than most homeowners expect.

Cost Breakdown

The concrete patio model starts with 20.5 Craftsman hours at the loaded wage of $58.39 per hour (Craftsman, 2026). That produces $1,197 in burdened labor once you include the 40.06 percent for taxes insurance and benefits. Materials add $1,503 after the latest FRED PPI adjustment. Permit sits at $0 in the index for this particular scope although your city may still attach stormwater or trade fees at issuance. Overhead allocation pulls $829 from NAHB benchmarks to keep the business running. Add those pieces and the cost to deliver reaches $3,529. The city average bid of $4,355 therefore carries a contractor margin of 18.9 percent. Stamped concrete jumps the average to $6,475 because the extra finishing hours nearly double the labor line. A basic concrete driveway replacement lands near $8,573 with its own $898 permit. Each line tells the same story. Labor and materials dominate. Meanwhile, the margin lives in the gap between $3,529 delivery cost and whatever the contractor quotes. Knowing exactly where those dollars go changes how you read the bid.

How to Negotiate

Seattle crews lose five to six months every year to rain. That compressed window creates real pressure from June through September. Shop your concrete patio project in early spring before the rush hits. You'll see more flexibility on price and schedule. The lowest realistic price sits at $3,888 for the standard concrete patio. Use that figure as your benchmark not as a club to beat the contractor over the head with. Tell him you've run the true cost numbers and you expect the bid to land somewhere between the floor and the $4,355 average. Then stop talking. Before you call anyone back run your specific bid through the Bid Fairness Checker on this page. It'll tell you in plain numbers whether the quote is fat or fair. The True Cost Calculator lets you adjust square footage and finishes so you enter the conversation with data instead of hope. Contractors respect preparation. In a market this expensive the prepared homeowner usually keeps more of the $467 potential savings.

What Makes This Market Different

No other major city combines Seattle's sky high wages with such a brutally short building season. The loaded rate of $58.39 per hour for concrete work is real. So is the fact that rain shuts down exterior pours from October through May. Wildfire smoke can halt work in late summer too. That squeezes the entire concrete patio calendar into maybe four good months. Median home values at $938,600 against $116,068 household income create a 7.6 price to income ratio that makes every patio feel like a luxury. Yet the housing stock built around 1974 means many properties need proper footings and drainage upgrades before any new hardscape goes down. Yet the cost index shows $760 in permit costs on footings and $1,102 on stem walls. Those numbers add up fast. I kept staring at the data because the margin on concrete patio work here's only 18.9 percent. That's lower than I expected given how expensive everything else is in this city. It tells me most established crews aren't padding these jobs heavily. They simply can't afford to lose the work during the narrow window when the ground is dry. The floor at $3,888 is therefore not some loss leader. It's what an efficient operator can charge and still stay in business. That surprised me.
