Metropolitan Maintenance Company

Formed in 1969 by Wayne Winterstein, Metropolitan Maintenance Company has grown from a start-up cleaning business to one of the largest privately owned commercial cleaning companies in Maryland.

Cleaning remains the core service offered today, but over the years a number of complementary services have been added. Customers now enjoy access to a comprehensive portfolio that includes Day Porter service, Power Washing, Carpet Cleaning, Window Washing, Temporary Labor, Flood Cleaning, Post Construction Cleaning, Grounds Maintenance and Restoration of Marble, Terrazzo, Ceramic and VCT.

Growth has come through reputation and recommendation. From its beginnings, in Towson, the business has expanded to cover all of Baltimore and the surrounding areas. Metropolitan Maintenance now cleans over 6 million square feet and employs in excess of 350 residents. With our local focus, we are big enough to handle any commercial cleaning solution you need but small enough to offer supervision and inspections at every property. Simply put, your satisfaction is our #1 priority, and we have the track record to prove it.

Our company’s ethos is to build a strong relationship with our customers. By fully understanding your needs, we can consistently meet – or often exceed – your expectations. Our staff training and systems are designed to ensure that we are responsive at all times.
