We're a Marsden Company!

Sunstate Mechanical is wholly owned by Marsden Holding. Marsden is a full spectrum facility services provider, offering janitorial, security, building maintenance, and specialty property services throughout the United States. Through Sunstate Mechanical's combined national support and local operations, we provide our clients with the strength of a large corporation with the individualized care of a small business.

National Scope

Marsden is one of the largest privately owned facility service providers in the United States. Marsden has over 50 offices throughout the United States and employs more than 10k people. Marsden has thousands of clients across the country and services over 300M square feet every day.

Local Dedication

Despite Marsden's national scope, Marsden focuses on the local markets in which it has acquisitions and office locations. Each office is invested in its community and local clients, providing personalized service. Like a small, local company, the regional offices make decisions on all aspects of their service operations and are empowered to manage their teams and respond to all client needs and requests.

Enterprise Resources

Marsden's local operating companies have the benefit of leveraging Marsden’s resources as a large organization – including staff, technology, equipment, supplies, information, industry experts, and financial support.
