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.
We didn't grow by cutting corners. We grew because the buildings we serve keep calling us back.
Our journey
Three decades of getting it done.
1992
Alliance Building Services founded in New York City. Maintenance and janitorial services for commercial properties.
2000s
Expanded into security services. Alliance Security launched to serve NYC's growing demand for integrated building protection.
2010s
Alliance Restoration added. Full-service platform complete — maintenance, security, and restoration under one company.
Today
4,000+ employees. 60M+ sq ft. Expanding nationwide. The same standard that built us — now growing beyond New York.
What drives us
Not a slogan. A standard.
01
Client focused
We listen first. Every property is different. Every client has specific needs. Our job is to understand them — then exceed them.
02
People first
Our 4,000+ employees are the reason we exist. We treat every person on our team with the respect, tools, and opportunity they deserve.
03
Always improving
Good enough isn't. We constantly evaluate our processes, invest in technology, and push to do the work better than we did yesterday.
04
Accountable
We own every outcome. When something isn't right, we don't deflect — we fix it. That accountability is why clients stay with us for decades.
05
Pride in the work
No task is too small. The detail work — the things clients notice when they walk in every morning — is what separates Alliance from everyone else.
06
One company
Maintenance, security, restoration — one team, one standard, one point of contact. That's what "one company" actually means.
Our divisions
Three services. One Alliance.
Commercial cleaning, janitorial services, and facility maintenance for NYC's most demanding properties — stadiums, office towers, residential, and everything in between.
Comprehensive security programs built around your property's unique needs — officers, surveillance, access control, and cutting-edge security technology.
Stone, metal, marble — exterior and interior restoration for New York's historic and modern buildings. Whatever the cause, we bring it back.
