Long Island's Premier Vinyl Window and Door Manufacturer for replacement and new construction. Take advantage of the Federal Energy Tax Credit today. Royal Windows and Doors is a replacement and new construction window and door manufacturer located in Suffolk County, on Long Island in New York State. We operate out of a 60,000 square foot factory located in Bay Shore, New York. We currently have two showrooms, one in Bay Shore and one in Commack New York. Since 1989 Royal has been manufacturing the highest quality upvc replacement windows as well as new construction windows. Royal was among the first companies nationwide to introduce a very high quality, all welded upvc vinyl window line. With the introduction of the Royal window line, vinyl windows could for the very first time, compete very favorably in looks, functionality and elegance, with the most recognized national brands of wood windows.
