About Us

Boston Sash & Millwork Inc. was conceived in the early 1990’s and was incorporated in 1994. The company was started with the expressed purpose of meeting a demand for turn of the century style window sash.


Since that time, most of the established window manufacturers have moved away from traditional window designs. These changes were in response to economic pressure to produce a faster and cheaper way to manufacture windows. Consequently, the industry has developed a shallow cookie cutter style that no longer reflects that quality of joinery, depth of profile, & delicate feel that was so important to the 18th and 19th century window makers.
