Concrete Contractors by City

- Licensed Concrete Contractors in Spokane, WA (33)
- Licensed Concrete Contractors in Tacoma, WA (20)
How to Read These Lists
Each city list includes only registrations whose status is ACTIVE in the L&I file dated Oct 30, 2026. Smaller markets such as Seattle, Tacoma, Spokane often have fewer than a hundred registered concrete contractors, which makes it quicker to compare every option.
Not every Washington city has a list yet: we publish a city once it has enough active registrations to be useful, and add more cities in stages.
How Concrete Contractors Are Licensed in Washington
Businesses that pour driveways, patios, foundations and other flatwork for others are construction contractors in Washington and must register with L&I under RCW chapter 18.27. In the L&I file they appear under the Concrete specialty. Registration brings a bond and liability insurance requirement, and our lists show both for every business.
Registration
Our concrete lists include businesses whose L&I specialty is Concrete. Masonry and general contractors also do concrete work; general contractors appear in our general contractor lists, and any business can be checked on L&I Verify.
Bond and Insurance
A specialty registration requires a $15,000 surety bond (RCW 18.27.040) and general liability insurance (RCW 18.27.050); a general contractor needs a $30,000 bond. If either lapses, the registration cannot stay active.
Permits and Property Lines
Work such as a new driveway approach, a retaining wall or a foundation can need a permit from your city or county, and work at the street may involve the public right-of-way. Ask the contractor who will check and pull any permit.

Bond and insurance coverage in our concrete lists is close to universal. The more useful filters are the registration date and expiry date: a business registered in the last year has less track record, and one expiring soon should show proof of renewal.
How to Check a Concrete Contractor Before You Hire
- Find the business in a city list below or on L&I Verify and confirm the status is ACTIVE.
- Check that the bond and insurance are on file and the expiry date falls after your project.
- Ask whether the driveway, wall or slab needs a city or county permit and who will get it.
- Put the thickness, reinforcement, finish and cleanup in the written contract.
- Avoid large upfront deposits; tie payments to completed stages.
