Quality Windows

Our Story

Eastern Shore Window and Door is our sister company on the Shore. Its owner Joe DelGrosso has trained and mentored our team, and has provided solid doors and quality windows to Maryland families for over 35 years.

We recently took on the new name of Maryland Windows and Doors for our work on this side of the shore, to reflect how our services reach families across 7 counties in Maryland, including Harford, Anne Arundel, Montgomery, Prince George's, Howard, and Baltimore County and City.

We treat all customers with the same respect as we would want to be treated. No high pressure, 2+ hour presentation, no BS "today only pricing." We are here to serve you to make the best decision for your family.

Our sales team is honest and informative, with absolutely no pressure. We leave you with all the information you need to compare prices with competitors, and are quick to follow up if you need any more support.

All of our services are priced very competitively, because we work directly with high tech manufacturing companies to provide high quality windows and doors at affordable prices for all our customers.

Our professional installation team has been working with our family company for 45+ years collectively. We are licensed, insured, and provide a service guarantee and up to lifetime product warranties.
