About System4 Milwaukee
Locally owned commercial cleaning for Southeastern Wisconsin businesses: one contact, one invoice, and crews that show up every time.
A Local Owner Who Builds Lasting Relationships

Randy Engmann started System4 Milwaukee in 2019. Before that, he spent his career in radio broadcast marketing, building campaigns for local Milwaukee businesses. That work taught him what matters most: long-lasting relationships and practical solutions. Today he applies the same approach to keeping workplaces clean and safe for employees and visitors.
System4 Milwaukee is part of the System4 franchise network, a facility services management model. That means you deal with one local point of contact, one phone number, and one invoice. Behind that is a network of qualified, experienced local cleaning providers. Randy works with each client to build a cleaning schedule around their business hours, whether that means evenings, overnights, or weekends. That way your team can stay focused on running the business.
“Managing the process is what sets System4 apart in janitorial and commercial cleaning. The compliment we hear most is about our responsiveness and account management. When you call, we answer, and we fix it fast.”
