Our Story
HSG was founded by Hector S. Garcia as HSG Professional Window Cleaners, Inc. a one-man window cleaning operation. As the company grew, Mr. Garcia hired additional personnel while continuing to perform window washing. In 1980, the company was renamed to HSG Inc to better reflect the full range of exterior curtain wall services the company had expanded to offer to its clients.
Today, HSG has offices in both Los Angeles and Orange County with a growing team of over 100 professionally trained employees. The field operations team is supported by a dedicated management team, fully trained in Safety Operations, OSHA regulations, and certified by the SAIA, SkyClimber, and PowerClimber. HSG’s internal structure is held together by a group of motivated professionals that have allowed the company the opportunity to grow in both size and reputation over the past four decades.
