The JB Proper Bostonian - We don't just make windows. We recreate history. Visit the JB Sash Site

  JB Sash & Door offers a turn-key solution from start to finish for the replacement of historical windows in Boston and throughout Massachusetts.

The Historical District Commission of Boston and neighboring towns continue to set rigid authenticity guidelines for historical replacement windows in buildings and homes. In fact, Boston is broken out into nine different districts, all with their own compliance requirements when it comes to historical replacement windows.

JB Sash & Door is at the forefront of these requirements providing a seamless process for any historical window replacement project.

Services Offered:

• We will work with the consumer to put together the "Historical Replacement Window Submittal Packet" complete with drawings, required forms and estimates.

• JB Sash will then do the heavy lifting by obtaining all the necessary historic commission approvals.

• We work directly with local architects, builders and remodelers to ensure your project is granted historic approval.
• Secure all necessary permits to complete job.
• Installation offered by JB installation crews.
• Free on-site measuring and estimate service.
• Job site delivery service available.
• Exterior and interior pre-finishing upon request.
