At A&D Window Washing & Soft Washing, we believe great service starts with great people. What began in 2016 as two high school athletes looking to create value in their community has grown into the most trusted name for premium window cleaning and exterior cleaning in Central Maryland.

A&D was founded by best friends Sam Alsheimer and Michael Doughty, friends since kindergarten who shared the same vision from the beginning: build something bigger than themselves. In 2016 we took an entrepreneurial risk driven by the idea that hard work, teamwork, and attention to detail could create a company people genuinely trusted.

Today, that same mindset still drives everything we do.

We have built a team made up of close friends and teammates from schools like University of Maryland, UMBC, Morgan State University, and Towson University, Our team culture is built around trust, accountability, discipline, and doing whatever it takes for the greater good of the team. We are proud to create an environment where our employees are excited to come to work, interact with customers, and take pride in delivering exceptional results.

As a family owned and operated business, we treat every property as if it were our own.
