Fog inside the glass usually means the sealed unit has failed — not the whole window.
When moisture appears between the panes, the seal has usually broken. In many homes the frame is still solid. CGR checks the frame, glass size, spacer, and access, then replaces only the sealed glass unit when possible.
CGR inspection checklist
- Fog or droplets between the panes
- Failed sealed glass unit

Foggy window glass replacement in Ottawa & Gatineau.
Condensation trapped between panes usually means the seal inside the thermos glass unit has failed. CGR replaces the insulated glass while preserving the existing window frame whenever it remains in good condition.
Signs your sealed glass unit has failed
- Moisture or haze between the panes
- Glass that stays cloudy after cleaning
- Cracked double-pane glass
- A window frame that remains structurally sound
Keep the frame. Avoid paying for a full-window replacement.
Pay for the failed glass only
When the sash and frame are sound, replacing the thermos glass avoids the cost of a new frame, trim, and full-window installation.
