Company History

Horizon Services Company started in 1991 as Horizon Industrial Services, a commercial cleaning contractor operating out of a warehouse located on North Main Street in Manchester, Connecticut. Over the next three decades, Horizon Services grew, and quality cleaning services were in high demand. Rapid company growth led to a new business model and a company-wide reorganization.
In 1994, Horizon Services Corporation (dba Horizon Services Company) was born. Under the leadership of President and CEO Ted Hsu, Horizon Services Company quickly outgrew its warehouse location in Manchester.

In 2000, Horizon moved its corporate headquarters to 250 Governor Street in East Hartford, Connecticut, where Horizon Services Company resides today and continues to operate its successful commercial cleaning business.

In 2005, new Branch Offices through New England states were established, servicing clients across the North East.

In 2010, Branch Offices expanded, establishing locations throughout the United States to service clients.

Horizon Services Company attributes its rapid growth to its dedication to quality assurance, continuous process improvement, and consistently maintaining a high management-to-staff ratio. Horizon Services Company's service-oriented business model ensures that our customers receive consistent, high-quality cleaning services. Horizon's remarkable growth in the past decade is a direct reflection of the quality of our cleaning services and the professionalism of our cleaning technicians, managers, and customer service personnel.

Horizon Services Company's proven quality assurance program and service-oriented business model ensure that every customer is given the same personal attention and high-quality cleaning services. While we have the privilege to work with many Fortune 500 companies and large corporations, we pride ourselves on extending the same level of customer service to all our clients, no matter the size of the organization or facility we service.

Today, Horizon Services Company continues to grow and expand, providing commercial contract cleaning, facilities management, and building maintenance services throughout the United States east coast. Horizon Services Company's impeccable facilities and services allow our customers to focus on running their businesses while we maintain a clean, safe work environment for their employees and customers.
