Concrete Contractor Cost in Seattle [2026]
Last Updated: 5/16/2026Concrete contractor pricing in Seattle varies based on project size, access, and the finish you want. The fastest way to get an accurate price is a site visit and a written estimate that outlines materials, preparation, and finishing.
Key factors that shape concrete pricing
- Square footage and thickness: larger slabs and thicker pours require more material and labor.
- Site access and prep: demolition, excavation, and grading can change the scope.
- Reinforcement: rebar, wire mesh, and base compaction add durability but also cost.
- Finish and design: stamped, stained, or exposed aggregate finishes take more time.
- Drainage and permits: proper drainage solutions and local requirements may be needed.
Typical project types in Seattle
Common residential projects include concrete driveways, patios, walkways, and foundations. Commercial work may involve loading docks, ADA ramps, or larger slab pours.
What a professional estimate includes
A reliable estimate should list demolition or removal, base preparation, concrete mix, reinforcement, finishing, and cleanup. It should also include a clear scope and timeline so you can compare bids fairly.
How to compare bids
Ask each contractor to explain the mix design, reinforcement, and finishing steps so you can compare apples to apples. If you are unsure what to look for, read our guide to choosing a concrete contractor.

Frequently asked questions
What does a Seattle concrete contractor typically charge?
Most flatwork (driveways, patios, walkways) runs $8–$22 per square foot installed in Seattle. Structural work like foundations and retaining walls is priced separately by linear foot or by project. Decorative finishes carry a 20–50% premium over plain broom-finish work.
What drives concrete contractor pricing in Seattle?
Site access, slab thickness, reinforcement scope, finish complexity, permit requirements (SDOT for ROW work), demolition of existing surfaces, and disposal. Hillside lots and tight backyard access add cost. SDOT approach permits add $500–$2,000 to driveway projects.
Are there hidden costs I should ask about?
Confirm whether the quote includes hauling and dump fees, control-joint sealing, finish-stage curing protection, and post-pour cleanup. Permit fees are usually billed separately. Get a written, itemized estimate before signing.
How do I compare quotes from multiple contractors?
Compare on the same scope: slab thickness, reinforcement type, finish, base prep, control-joint placement, demolition of existing, permit handling, and disposal. A quote 30% lower than others usually skips one of these line items.
What is the typical cost for an SDOT permit?
SDOT driveway approach permits typically run $500–$2,000 depending on scope and right-of-way impacts. Larger commercial right-of-way work and sidewalk replacement permits can run higher. Costs are passed through with no markup on the contractor estimate.
