Optimize Your Workplace©

We're a Marsden Company!

What does it mean for CleanPower to be a Marsden company? Well, it means that we are part of one of America’s largest privately-held commercial cleaning and security firms. Supporting 25 distinct brands under one umbrella is unique in our industry. But we think it is a better way to serve our thousands of clients.

National Scope

Our approach to providing nationwide coverage is different than our competitors. We have 25 wholly-owned operating companies that employ 10,500 people, covering 46 states, which everyday help American businesses, schools, and government entities keep 300 million square feet clean, cool, calibrated, and safe. While each company is deeply rooted in their hometowns, together we are a coast-to-coast powerhouse, ready to handle any need, big or small. That’s the Mardsen Way.

Local Dedication

We self-perform an astonishing 97% of our business. When we bring new companies into our family we keep their local offices and maintain human resources and recruiting in the community, which allows us to invest in our clients – by really being there. We believe our clients want the hometown team, but also want deep and meaningful support from a sophisticated partner.

Great Resources

One of the benefits of being a part of a firm like Marsden is that we can share resources from all of companies, producing exciting new content. You can listen to our new Building Intelligence Podcast©, find a library of white papers, and follow our blog. All of it is available at our brand new website at www.marsden.com. And check out our new social media presence!

We are the experts that provide you and your stakeholders a clean, cool, safe, and optimized workplace. The result? Employees and customers who return because they feel healthy, comfortable, and secure.

commercial-hvacKeeping your facility comfortable can be a challenge, particularly as seasons change. Having a partner who can design, recommend, install, and maintain your heating and cooling systems can make all the difference.

At Marsden, we focus our efforts on outcomes that limit complaints, lower your total cost of operation, and improve efficiency.

The single biggest complaint made to respondents to the Building Operating Management survey was temperature — with 68 percent of respondents stating temperature in the office was their number one issue. Temperature is also the largest daily source of complaints — 16% of respondents say they field a hot/cold call every day.

How do we innovate? By using predictive analysis to identify measures that result in dramatic cost savings over traditional mechanical approaches. To learn more about our complete line of services click here.

Special Report

The Case for Vendor Consolidation, by Guy Mingo, CEOGuy Mingo

“With Marsden Holding, customers get a national presence with local dedication,” says Guy Mingo, CEO of the St. Paul-based commercial cleaning powerhouse. That statement seems to be the unofficial motto of the company as the phrase is reiterated by not only Mingo but several of the presidents of the companies Marsden Holding has acquired.

Comprised of 23 companies operating in 46 states, it’s easy to see what Mingo means about national strength. However, to understand the other part — being a local player — one simply has to look at a few of Marsden Holding’s larger acquisitions: SCIOTO Services of Columbus, OH; Aztec Facility Services of Houston, TX; or CleanPower of Milwaukee, WI. None are known as Marsden Holding, but rather they maintain their vitally important regional identity. Complete story here.


While we at CleanPower offer building maintenance in Wisconsin, as well as facility services in Wisconsin, our parent company, Marsden Facility Services, offers services all across America.

Collectively, we are dedicated to the delivery of superior service to your business – anywhere coast to coast. The Marsden companies are responsible for over 300 million square feet every day. We clean, climatize, calibrate, and protect your important assets.

We’re different because our operating companies are deeply entrenched in their local communities, allowing us to self-perform an astonishing 97% of all our business. While we enjoy the efficiencies of a national company, we allow our operators to make decisions and build relationships in the communities where they work and live. National Scope. Local Dedication.
