About Us

Family owned and operated, D&M Enterprises was started by Doug and Mary Dillard in 1968. D&M, or “Dad & Mom” as it has been sometimes affectionately called, was located in Potomac, Maryland, later in Washington, DC, and now in Gaithersburg, Maryland.

Out modest beginning…

D&M’s roots were as a gutter cleaning and service business to earn a little extra money to help the family make ends meet. As the business grew it became a part-time business evolving later into a full time roofing, gutters, and skylights repair and replacement company serving the Washington Metropolitan area.

We get a bit bigger…

The brothers, Troy and Todd grew up working summers and weekends in the family business and after acquiring ownership in 1987, moved the business in 1991 to its current Gaithersburg location.

Our service offerings increase…

The company began to offer a complete line of exterior home improvements and remodeling services including windows, doors, siding, soffit, trim, shutters, decks, porches, storm windows/doors, painting and related interior remodeling. These products have been a very exciting addition to the business.
