Northwest Building Maintenance Inc. was founded on December 6, 1996, in Spokane, Washington by Bill Duffy III with a simple but powerful goal: to provide reliable, high-quality commercial cleaning services built on integrity, consistency, and long-term relationships.
Starting as a locally owned and operated janitorial company, Northwest Building Maintenance quickly earned a reputation for dependable service and attention to detail. From the beginning, Bill believed that successful facility maintenance required more than just cleaning—it required accountability, strong communication, and a genuine commitment to client satisfaction. Those principles became the foundation of the company and continue to guide operations today.
Over the years, Northwest Building Maintenance Inc. has grown alongside the Spokane community, expanding its services to support a wide range of commercial, medical, industrial, and professional facilities. Despite that growth, the company has remained true to its roots as a hands-on, service-driven organization that values trust and long-term partnerships.
Northwest Building Maintenance stands as a testament to nearly three decades of dedication, experience, and local leadership. The standards established by Bill Duffy III in 1996 continue to shape the company’s culture—delivering dependable cleaning solutions, maintaining safe and healthy environments, and serving Spokane-area businesses with pride and professionalism.
