Before you compare quotes in Alameda County

Records checked 2026-10-06. Listings include the C-8 classification, source status CLEAR and an unexpired license at import. They do not establish workmanship, customer reviews, current availability or participation in our referral service. Confirm each record with CSLB's license checker.

County counts use the county reported in the CSLB business record. A business can work outside its mailing city or county; ask whether your address is covered. We do not publish exact business addresses, phone numbers or personnel records.

Match the contractor to the work

A driveway replacement, decorative patio and structural slab need different project briefs. Send photos, dimensions, intended use and access constraints. Ask bidders to separate demolition, disposal, base preparation, drainage, finish and curing protection. Confirm who handles permit questions with the authority for the property.

The C-8 classification identifies concrete work in the license record. It does not tell you whether a business takes small residential repairs or has experience with your chosen finish. Request comparable completed work and a written scope.

Compare the complete quote

Use the same project description for each bidder in Alameda County. Include changes in elevation, water pooling, access for deliveries and anything that must stay usable during construction. Ask which assumptions could change the price and how changes are approved.

Our cost guides describe national estimates, not a California bid. Use the concrete calculator to check quantities once the dimensions and design are established.

How requests are handled

A listing is a public record, not confirmation that the business accepts referrals. We review your request and seek up to three suitable contractors. California records do not supply email addresses, so matching may require manual contact. Availability and a response are not guaranteed.
