Accent Building Maintenance

6372 Copps Ave.

Accent Specialty Services (Accent), formerly Accent Building Maintenance, has been providing outstanding commercial janitorial services to Northeastern Wisconsin since its founding in 1989.  Accent became a Vonachen Family Company in 2014 and continues to carry forward the core values that it was founded on – as a family-owned company.  Specialty Services of Wisconsin Inc., a commercial cleaning company serving Madison, Wisconsin and the surrounding area, became a member of the Accent Specialty Services family in 2016.

To this day, Accent continues to deliver quality janitorial services to numerous business sectors, including educational institutions and industrial facilities. We also handle a variety of special maintenance projects, including detailed construction cleanup projects for a marine company located in Marinette.  Accent continually strives for exceptional customer service and green cleaning solutions that fit the needs of any business.

In 2016, Vonachen Group, the parent company for Accent Specialty Services, DSI, K-tech Building Maintenance and Vonachen Services, Inc., was established to better serve its clients and employees, finding a benefit in shared resources and services.  As our companies continue to grow, Vonachen Group will continue to focus on the core values that have made its companies successful: honesty, integrity and a dedicated work ethic. Our people have been and continue to be our greatest asset allowing us to grow in a strategic manner.
