On January 1, 2026, Northwest Building Maintenance entered its next chapter under the ownership and leadership of Karl Bowen. Karl has more than 35 years of experience in the commercial cleaning industry and a proven track record of operational leadership. Since 2013, he successfully operated a competing commercial cleaning company in the Spokane market, building deep local relationships and a reputation for quality, compliance, and results.
This transition represents both continuity and growth—honoring the strong foundation built by Bill Duffy III while positioning Northwest Building Maintenance for the future through expanded expertise, modern systems, and renewed investment in people, processes, and client partnerships.
