Diamond Windows

Diamond Windows Boston Massachusetts

Diamond Windows & Doors was founded in 1992. After years of experience in the big apple, Tony decided to take his knowledge to Boston and start Diamond Windows & Doors. Using his understanding of the industry, Tony has made it his goal to meet and exceed the requirements of architects, developers, and homeowners. With this knowledge and the contacts that he has made over the years, Tony soon had a successful window manufacturing business operating out of a 20,000 sq. ft. facility in the Brighton-Allston neighborhood.

Following the exact standards required in the construction industry, Tony has stayed true to his roots. Knowing that the quality of a house, loft, or condo is only as good as what you put in it, Diamond seeks to maintain a high standard for our products. With this in mind, our vinyl windows have already evolved into a third generation of better-performing windows as we continually look for ways to improve our product.
