Locally Owned.
Family Operated.
Trusted for Over 30 Years.

At MLSK Windows and Doors, we’re more than just a business—we’re a family. Founded by Duffy and named in honor of his four daughters—Molly, Lindsey, Sadey, and Kassidy—the company has been a trusted part of the community for over 30 years. Today, Duffy and his daughter Sadey continue to lead the way, providing personalized service and a commitment to quality. As a locally owned and operated business, we take immense pride in enhancing homes with the finest windows and doors, while staying true to the core values that have guided us for three decades: honesty, integrity, and attention to detail.
