Glass Replacement & Window Reglazing

Cracked, foggy, or loose window glass? We can help.
At Whole Window, we specialize in glass replacement and reglazing for wooden windows across Boston and surrounding areas. Whether you have a cracked pane, failing putty, or aging glazing — we restore your windows quickly and beautifully.

What Is Window Reglazing?

Reglazing is the process of securing window glass into a wooden sash using new glazing putty. It’s essential for maintaining a weather-tight seal, proper insulation, and preserving your window's structural integrity.

When to Reglaze or Replace Glass

Cracks or chips in the glass
Loose, rattling panes
Dried, crumbling, or missing glazing putty
Drafts or moisture around the sash
Condensation or fogging (in double-pane units)

Our Process

Inspection & Consultation
We assess whether your glass can be reglazed or needs full replacement. Whenever possible, we preserve the original pane.
Careful Glass Removal
If needed, we remove the damaged glass safely and prepare the sash for new glazing or pane insertion.
Custom Glass Cutting
We cut glass to fit your exact sash dimensions — including single-pane, laminated, or historic restoration glass.
Professional Reglazing
Using traditional putty or modern glazing compounds, we install the pane securely and neatly, ensuring both function and aesthetics.
Curing & Painting (if requested)
Reglazed windows are left to cure, and can be primed and painted to match your existing window finish.

We Work With:

Historic wood windows
Single-pane and true divided lite windows
Energy-efficient glass upgrades (optional)
Glass in fixed frames or movable sashes
