SourceContractors State License Board (CSLB) License Master, retrieved 4 Oct 2026.

The License Master file includes licences that are currently renewed or expired but renewable. Licences that are cancelled, revoked, or expired and not renewable are not in it, so a licence missing from this register proves nothing about it.

This page shows the record as of the date we retrieved it, so the licence may have been renewed or changed since. Confirm current standing with the board: search licence number 643197 on CSLB Instant License Check.

The board publishes contact details for its licensees; we do not republish addresses or phone numbers. You will find them on CSLB Instant License Check.
