Foggy Window? Save the Frame, Just Replace the Glass
When thermal pane windows start to fail, moisture forms between the panes and creates the classic foggy look. When it happens, call the experts at City Window & Glass. We replace only the glass, not the frame, saving you thousands of dollars. Send us a photo of your window for an initial assessment.

Why It Matters
Why Consider Thermal Pane Replacement?
Windows are more than panes of glass — they're your home's first line of defense against the elements. Thermal pane windows are built to last 10–15 years. If yours are foggy, you're losing the insulation you paid for.

The Replacement Process
How We Fix Foggy Windows
Double or thermal pane windows serve a dual purpose: they block out external temperature fluctuations and keep your climate-controlled air inside. When the seal fails, moisture creeps in and the insulating argon gas escapes. Here's how we get you back to clear, efficient windows.
Final Inspection
We guarantee the job is done right with a thorough final inspection before we leave.
Selection & Installation
Choose from clear, frosted, tinted, or textured glass — each with a different look and feel for your space.
Assessment
Our team evaluates the condition of your windows to determine the extent of the issue and confirm the seal has failed.
Before and After
The Difference a Glass Replacement Makes
Replacing just the failed glass unit (not the whole window) delivers immediate improvements without the cost or disruption of a full window replacement. Here's what to expect.
Failed Thermal Pane
Before
What you're seeing right now, and why it's worth fixing. A broken thermal pane seal means your window has lost its insulating gas, moisture has worked its way between the panes, and the appearance of the glass has degraded. Beyond the look, you're losing energy efficiency every day the window stays in that condition.
Best For
Identifying the signs
Applications
Foggy glass between the panes · Visible condensation that won't wipe away · Failed seal around the glass unit · Cloudy, hazy, or discoloured appearance
After
What your window looks and performs like after we replace the glass. Your existing frame stays in place, the new sealed unit restores the insulating gas and clarity, and you get the same performance as a brand new window at a fraction of the cost of a full replacement.
