Boston is one of America’s most historic cities — and its neighborhoods are full of beautiful homes that deserve windows worthy of their architecture. Whether you own a Victorian in Jamaica Plain, a Federal-style townhouse on Beacon Hill, or a Colonial in Newton, replacing the windows in a historic home requires expertise that most contractors simply don’t have.
Here’s what Boston homeowners need to know about replacing windows in older and historic properties — and why choosing the right contractor makes all the difference.
The Challenge: Historic Homes Don’t Have Standard Windows
Homes built before 1940 — and many built through the 1960s — rarely have standard-sized window openings. Decades of settling, renovation, and remodeling mean that every opening is slightly different. Many older windows also have architectural features — historic sash profiles, divided lights, decorative muttons — that contribute to the home’s character and, in some cases, need to be preserved or replicated.
Off-the-shelf windows from a big-box store simply will not fit correctly. They require shimming, modification, and filler trim that looks wrong and performs poorly. The only right solution for a historic home is custom, made-to-order windows — measured to the exact dimension of each opening.
Landmark and Historic District Considerations
If your home is in a designated historic district — such as the Beacon Hill Historic District, the Bay Village Landmark District, or a local historic area — there may be guidelines about what types of replacement windows are permitted. Common requirements include:
- Maintaining the original divided-light pattern (true divided lights or simulated divided lights)
- Matching the original profile and sight lines
- Using specific materials (often wood or wood-clad)
- Preserving or replicating exterior trim details
Boston Doors & Windows has experience working with homes in and near historic districts. We can help you select products that meet any guidelines while still delivering the energy performance and durability you expect from new windows.
What Makes a Good Historic Replacement Window?
For historic and high-end homes, we typically recommend wood or wood-clad window products from manufacturers like Marvin and Andersen. These offer:
- Authentic profiles: Sight lines and proportions that match traditional double-hung windows
- True divided lights or SDL: Options that preserve the visual character of original multi-pane windows
- Custom sizing: Made to fit every unique opening in your home
- Superior energy performance: Modern insulating glass in a traditional profile
- Low-maintenance exteriors: Aluminum or fiberglass cladding protects wood interiors from New England’s harsh winters
Whole-Home Replacement in a Historic Property
Many of our most rewarding projects have been full whole-home replacements in historic Boston homes. A recent project in Brookline involved 20 custom-sized double-hung windows in a 1920s Colonial — every window measured individually, custom ordered, and installed over three days. The homeowners kept the home’s original character while dramatically improving comfort, noise reduction, and energy efficiency.
Another project in Dedham involved 30+ windows in a large Victorian. Our crew handled the full project seamlessly — from careful removal of the original sashes to precise installation of the new units — without disturbing the original interior trim and plasterwork.
Questions to Ask Any Contractor Before You Hire
- Do they work with made-to-order windows, or off-the-shelf products?
- Have they worked in historic districts before?
- Can they show you examples of similar projects?
- Do they handle the measurement themselves or outsource it?
- What happens if a window doesn’t fit correctly?
At Boston Doors & Windows, the answers are: yes, yes, yes, we do it ourselves, and we stand behind our work 100%.
