Foggy window glass · Ottawa & Gatineau

Replace foggy window glass, not the whole frame

Cloudiness or moisture trapped between your window panes usually means the sealed glass unit has failed. CGR Window Glass Replacement & Repair can help replace the insulated glass unit while keeping your existing window frame when it is in good condition.

Foggy window glass replacement

Foggy Window Glass Replacement in Ottawa

If the haze is inside the glass, a failed sealed unit may be the cause. Book a free measurement or call us to discuss replacing the insulated glass without replacing a sound window frame.

Why a window looks foggy between the panes

Modern insulated windows are made from two or more panes sealed together. When that seal fails, humid air can get between the panes and leave haze, condensation, or mineral marks that cannot be wiped from either side of the glass.

Replace the sealed glass unit, keep the window frame

A fogged pane does not automatically mean you need a whole new window. When the sash and frame are in good condition, replacing only the sealed glass unit can restore a clear view and the window’s insulating performance. We confirm what is appropriate for your window before work begins.

Start with a free at-home measurement

Book an appointment online or call us. A CGR technician will come to your home in Ottawa or Gatineau to measure the thermos glass, inspect the frame and access, and prepare your quote. Photos are optional.

Questions about this service

How do I know if my sealed window unit has failed?

If the fog, moisture, or streaking is trapped between the panes and cannot be cleaned from the inside or outside surface, the insulated glass seal has likely failed.

Do I need to replace my whole window?

Not always. If the existing sash and frame are sound, the sealed glass unit can often be replaced on its own. We assess the window before confirming the solution.
