All of San Bernardino County · All California counties
California contractors are licensed by the CSLB. A license record shows its classifications, status and bond and workers' compensation filings. Check which classification covers your specific foundation or waterproofing scope.
Look up the business in the CSLB public search before you sign. A credential shows legal standing at most. It does not show that a business does foundation or waterproofing work, so we show separate, dated service evidence where we have it. Neither is a rating of workmanship. How we verify listings.
