Where it began
1992

One company. One standard. New York City.

Alliance Building Services was founded in 1992 with a simple belief: New York's most demanding properties deserve better. Better service. Better people. Better accountability.

What started as a building maintenance company has grown into one of the tri-state area's most trusted facility services platforms — spanning maintenance, security, and restoration under one roof, with 4,000+ professionals working every day across 60 million square feet of the city we call home.

Our approach begins with each client's specific needs. A unified management team, seamless communication, the latest industry technology, and cost-effective procedures come together to build the most dynamic solution for every facility we serve.

We didn't grow by cutting corners. We grew because the buildings we serve keep calling us back.

Partnering with Alliance means you can concentrate on the core of your business.
