Our Factory

Diamond Windows & Doors MFG originally operated out of a 20,000 sq. ft. facility in the Brighton, MA.  The quick growth of the company soon necessitated a move to a larger facility.  In 2004 Diamond Windows moved all of its offices and manufacturing systems to the more centrally located Dorchester neighborhood of Boston.  With a new 100,000 sq. ft. facility with easy access to I-93 and I-90, Diamond Windows is poised to better serve all of New England.

With more room to expand, Diamond Windows took the opportunity to update all its machinery when it moved.  Our state-of-the-art manufacturing capabilities allow us to make the highest quality window possible.  The new factory floor even opened enough room to accommodate the machinery needed for introducing a product expansion into aluminum windows.  This product expansion effectively brought Diamond Windows into the commercial market, making us your complete windows solution, whether you are working on a small residential property or on a large scale commercial building.
