About DG Windows
Discover our commitment to quality and service in window and door installation for your home.
Our Journey and Values
Founded by a dedicated father-and-son duo, DG Windows has been a cornerstone of quality window and door solutions for more than 45 years. Our mission has always been to provide exceptional craftsmanship and truly personalized service, treating every project with the care and attention it deserves.
The company’s story began when Dennis launched the business alongside his family in 1979, building it from the ground up through hard work, integrity, and a reputation for getting the job done right. Over the years, DG Windows secured and serviced major accounts—including the Annapolis Naval Academy, Home Depot, and a number of high-profile celebrity residences—delivering work that consistently exceeded expectations. Strong family values and a commitment to quality quickly became the foundation of the company’s long-standing success.
Today, Dennis Giammetta leads the company, with his son playing an active role in marketing and sales. The team also includes Michael Romeo, who brings more than 45 years of carpentry and metal fabrication experience to the business. Together, they combine craftsmanship, expertise, and customer-focused care to continue the DG Windows legacy.
