About Alliance Building Services

Founded in 2006 in Bellevue, Washington, we were created with a clear vision: to deliver exceptional quality and value through reliable, professional building maintenance.

Our Story

What started as a small operation in Bellevue has grown into one of the region's most trusted building services providers. Today, we serve more than 250 accounts throughout Washington State, from commercial office buildings and high-tech campuses to industrial facilities, medical centers, and retail environments. Our growth hasn't changed who we are. We're still locally owned, still committed to the same values that got us here: do quality work, treat people right, and show up when you say you will.
