About us

Our Story

Keenwick was founded in 1999 by Jimmie Steinberg Jr. After recognizing the growing demand, he created one of the first window cleaning companies in the Annapolis area. Years later, our house washing service was adopted as another means to satisfy our customers.

Now second generation owned, Jimmie Steinberg III brings years of customer service and market analysis to the table. In addition to job experience, Jimmie III holds a Bachelors Degree in Business Management from Salisbury University.

Keenwick has grown into one of the most well respected and trusted window cleaning and power washing companies in Maryland. We have earned this reputation by providing each individual customer with unmatched customer service, workmanship, and cleaning solutions.
