Use this page when you need a California C-4 license lookup, a list of licensed boiler, hot water & steam contractors, or a quick screen before assigning boiler, hot water & steam work to a sub. Each row links to a contractor profile with CSLB status, workers' comp, bond, federal records, and permit checks.
California has 721 CSLB C-4 license records for boiler, hot water & steam contractors. 97% currently hold active licenses and 13.6% have at least one federal compliance record. SiteVetter checks CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, EPA environmental records, and building permits in seconds.
For boiler, hot water & steam work, 13.6% of licensed contractors have federal records that a standard CSLB license check would not reveal. SiteVetter's 6-source lookup gives GCs a faster way to compare subs before bid award, onboarding, or renewal review.
Data sourced from California Contractors State License Board and federal databases. Updated weekly. For official verification, check directly with CSLB.
