In addition to these standards, Boston Sash & Millwork has a custom division able to address the unique or "nonstandard" Millwork situations. The use of Mahogany and other wood species are also used to increase the life span of the window. Unique shapes and sizes are efficiently produced or reproduced. When an architect writes "T.M.E" (To Match Existing) on your plans, Boston Sash's custom division can meet your specifications!

Let Boston Sash help you with your next window project, keeping in mind that they offer: block and tackle tilt balances, concealed balances with a parting bead, weight and chain systems.
