Company History


Hector S. Garcia began HSG Professional Window Cleaners, Inc. as a one-man operation in 1980. During the initial two years of operation he performed ground floor retail window cleaning and residential window cleaning. Besides performing the work himself, he composed proposals, prepared billings and payables, and organized a growing business.

As the company grew, Mr. Garcia took on the hiring of additional personnel while continuing to perform window washing. He individually trained and supervised new workers and worked side by side with them up until 1986. He also dealt with all the administrative duties of his growing company.

In order to better reflect the full range of exterior curtain wall services being provided to its clients, the company was renamed HSG adopting the tag line of "Building Surface Maintenance and Restoration".

Presently, HSG has offices in Los Angeles and Orange County with a growing team of over 100 professionally trained employees. Our operations team is supported by a dedicated management team led by Steven Williams, the General Manager, who has over 15 years of experience in Operations. 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 three decades.
