5 Best Concrete Companies in Seattle (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 7 min read

Concrete companies in Seattle cover more ground than most people expect, from scanning a slab before drilling to demolishing an old patio to fixing a leaking foundation. Ratings on this page run from 4.5 to a perfect 5.0, but only one business actually pours and finishes new concrete; the rest specialize in scanning, demolition, or foundation and masonry repair, so matching the right business to the job matters here.

Short answer: Graypaw Concrete Contractors is the only true concrete-pour specialist among Seattle's top-rated results, at 4.9 stars across 46 reviews. Rainier GPR, Expert Masonry and Foundation Repairs, Northwest Rock and Concrete Demolition, and Seattle Elite masonry and foundation repair all hold strong ratings but serve adjacent needs: scanning, foundation repair, and demolition rather than new concrete work.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other Seattle-area businesses returned for this search. Confidence weighs the rating by that volume, so a 4.9 from dozens of people carries more weight than a perfect score from a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

Is this a new-pour job, a repair, or a demolition, and does the business handle that specific scope?

What is the timeline from quote to project completion?
Is a permit required, and who pulls it?

Frequently asked questions

How did you choose these concrete businesses?

We started from every business returned in Seattle’s concrete-company search results with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Are all these businesses actually concrete-pouring contractors?

No. This search surfaced a mix of specialists: scanning, demolition, and foundation waterproofing companies, alongside one genuine new-concrete-pour contractor, Graypaw Concrete Contractors. Each intro above states clearly what the business actually does.

Which business should I call for a new driveway or patio?

Graypaw Concrete Contractors is the clearest fit on this page for new concrete pours like driveways, patios, and slabs.

The bottom line

Graypaw Concrete Contractors is the only true new-pour specialist here and the pick for a driveway or patio. For related jobs, foundation cracks, basement leaks, old-slab removal, or pre-drilling scans, the other businesses on this page each have a specific, well-reviewed lane.
