Plan A Project


If you are a homeowner, developer, or architect looking to start a project, please contact our office or email sales@diamondwindows.com to inquire in more detail of our products and pricing as everything is made-to-order.

We will try our best and schedule a meeting in person for the initial phase of the project, given that it is a large enough job that such service is needed. This service includes but is not limited to preliminary inspection of the building, window type consultation, assessment of overall window condition, and mock-ups if we decide to go forward. As we are based in Boston, Massachusetts, being closer to us will greatly affect timing of project site visits, however, if you are in the tri-state area or beyond, we will still be more than happy to help.

Note: If there is an existing historical window or any aluminum window that you do not see being offered in our commercial product line, we will have our engineers design and build that product for you. From all the projects we have done, every time we meet a challenging architectural shape, we grow in strides and perfect our craft.
