Contract Services Group (CSG) has been providing 37 continuous years of cleaning and related services to the commercial market place.

From its inception in 1973 with two clients the company has progressed to where it is a significant regional facilities services contractor.

In 1973 John Pearce founded the company with the objective of providing consistent quality cleaning to high-profile commercial buildings in Southern California. The company enjoyed immediate success with an independent major property owner awarding the company a 200,000 square foot office facility on a handshake. That handshake agreement remained in effect for more than twenty-five years until the building was sold.

From its inception CSG has always been guided by the standard established by its founder, “provide quality services to our clients at competitive prices, always treat our employees with dignity and respect, and abide by all government rules and regulations.”

CSG grew gradually every year over its first nine years. In 1983 CSG started providing high rise window cleaning with the purchase of Superior Window Cleaners. Commercial window cleaning became and has remained a core operating group within the organization.

In 1984 CSG was selected to be the cleaning contractor of the opening team of the Ritz Carlton Hotel, Dana Point, California. Thus began CSG’s journey to become a premier provider of services to the hospitality industry. Safety has always been an integral component of the CSG culture. With its desire for Safety Excellence! CSG saw a need in its operating market for quality services for high-rise window washing equipment. In 1990 CSG began inspecting and certifying permanently installed window washing systems, and 1991 installed its first window washing system on a major medical facility.

Over its first twenty years the foundation for it growth going forward was developed with three distinct operating units, commercial janitorial services to high profile facilities that require quality services, window cleaning to high-rise buildings, and service and installation of window cleaning systems.

Going forward the CSG philosophy is to stay focused in providing services within its core competencies, while continuously improving the delivery of those services.
