Millwork - Historical Work

There are few companies in the United States that know how to design and build historically accurate windows. JB Sash happens to be just such a company. The JB Proper Bostonian line of replacement windows is approved by the Boston Historical Commission (among others). JB Sash is the industry leader in designing, building, installing and painting these beautiful works of art. See some examples below and click here for a brochure of the “JB Proper Bostonian” Replacement Windows.
