The firm also operates under the WRKB Builders Inc. corporate entity, maintaining CSLB registrations for general building and specialty trade classifications. Design-build scope extends from pre-construction budgeting and permitting through final punch-list completion, including post-construction glass and surface detailing coordinated with crews like Crystal Clear Window Washing before certificate-of-occupancy walkthrough.
