Licensed Commercial Electrical Work, Built for San Antonio
-
Licensed and Ready for Any Scope
FSG holds active electrical licenses (#17904, #24643) and a Texas security license (TX B19407), backing every project with the credentials San Antonio facility managers need to see before signing off on work. Since 1982, that license has covered full-scope commercial electrical contracting: new construction, tenant build-outs, design-build and engineering, plus 24/7 emergency repair when equipment fails outside business hours.
