26 businesses with a current C-15 flooring license and an address of record in San Mateo, verified against the CSLB register on September 8, 2026. Nothing else gets a business on this list — not a sign-up, not a review score, not a payment.
Every business here holds a current C-15 Flooring and Floor Covering license with California’s Contractors State License Board, taken from the board’s own register on September 8, 2026 — not from a sign-up form. A C-15 means a passed trade exam, a $25,000 bond on file, and workers’ comp or a signed exemption. What the license does and doesn’t tell you →

It has to be on the contract, the estimate, the truck and the business card. A contractor who can’t produce it on the spot has answered the question.
CSLB’s Check a License page. Numbers only — a “license” with letters in it is not a CSLB license.
“Current and active” is the start. Confirm C-15 is on the classification list, the bond is in force, and workers’ comp is either carried or the exemption is signed — an exempt business that shows up with a crew is uninsured on your property.
Then do the part no registry can: three bids, references from jobs over a year old, and a written contract. Hiring a flooring contractor covers what to ask.
Every business here was taken from the CSLB register on September 8, 2026, not from a sign-up form. The verified block on each card comes from the state record and only changes when the record does. A business that wants a correction should correct it with the board; it will flow through on the next build.
If a sponsored position is ever offered, it will be labeled as one, and it can only reorder businesses that already qualify. It cannot put an unlicensed business on this page. That rule is the page.
License status is as of the date shown on each card and can change at any time. The board does not endorse any contractor, and neither does this list — a license means the minimum legal standard was met. Check the current record before you sign anything.
