For over fifteen years, Diamond Windows & Doors has been growing and adapting to the needs of our customers. Since the company’s humble beginnings in Brighton, we’ve worked hard to make sure you finish your project with the quality that your customers expect out of you. Out of our Boston factory, all our windows are made to order so that we can meet your every need. As a manufacturer, we pride ourselves in being able to turn around a window order quicker than the industry standard. This is just another way we work for you.
