Allied Building Service Co

Allied Building Service Co holds a 4.1-star rating from 43 customer reviews and serves the Detroit metro area from its headquarters in the historic Corktown neighborhood. Founded in 1948 as a small general contracting firm, the company has grown into a diverse operation offering facility maintenance, construction, electrical contracting, plumbing, janitorial, and window cleaning services. The business operates Monday through Friday from 8 AM to 5 PM, with emergency service options available for commercial property managers and industrial clients across the region.

What distinguishes Allied Building Service is its November 2025 partnership with Continuum Services, a leading facility management provider based in Farmington Hills, Michigan.

The company operates under the Team Allied banner and emphasizes a values-driven culture centered on teamwork, continuous improvement, and community investment. Their service model combines multiple trades under one umbrella, allowing commercial clients to consolidate vendors for plumbing, electrical, and general maintenance needs.
