Marvin is known throughout the country as a leader in custom windows and doors and in fact, “Marvin is the largest made-to-order wood window and door manufacturer in the world.” Unlike other window manufacturers, Marvin does not stockpile an inventory of completed products. Instead they build each order with their customer’s requirements specifically in mind. By doing things this way, Marvin can offer the industry’s most extensive selection of shapes, styles, colors, and overall options. As Marvin’s reputation for ethical business practices is second to none, different generations of the Marvin family are still actively involved in the day to day operation as they have been since the turn of the century. As customers needs have changed over the years, Marvin’s continued dedication to quality and innovation have never wavered.
