How to hire a concrete or masonry contractor in Phoenix
Updated July 2026
Concrete and masonry are two different licensed trades in Arizona that often get lumped together. Knowing which one your project actually needs, and checking the right license, is the first step before you hire.
Check the license, and the right class
Arizona splits this work into two separate license classes: R-9 or CR-9 for Concrete (poured flatwork like patios, driveways, and slabs) and R-31 or CR-31 for Masonry (block, brick, and stone walls). Many contractors hold both, but not all do, so confirm the contractor's license covers the specific work you need, not just that they have some kind of ROC license. Ask for the license number and look it up on the ROC public license search to confirm it is active and classed correctly for your job.
Questions to ask before you sign
Ask for a written, itemized estimate covering square footage or linear footage, the finish (plain, stamped, stuccoed), and whether demolition or removal of existing concrete or block is included. Ask about reinforcement (rebar or wire mesh) for slabs, since this affects crack resistance in Phoenix's expansive soil. Ask whether the quoted price includes any required permit, and get warranty terms on both materials and labor in writing.
How VettedAlready verifies pros
We check a contractor's Arizona ROC license status against the state's own public records, we do not just take a business's word for it. A verified badge means the license was confirmed active for that business, in the correct class, at the time of verification, not an endorsement of their work quality.

Frequently asked questions
Do I need one license or two for concrete and masonry work?
It depends on the job. Concrete flatwork (patios, slabs, driveways) needs an R-9/CR-9 Concrete license; block, brick, or stone wall work needs an R-31/CR-31 Masonry license. Some Phoenix-area contractors hold both classes and do both types of work; confirm which class covers your specific project.
How do I verify a contractor's license?
Use the Arizona Registrar of Contractors' public license search with the contractor's name or license number, or check their status on our verify page, which cross-references the same ROC records.
