Why Your Windows Fog Up — and
How to Fix Them in Winnipeg’s Climate
Cloudy, fogged-up windows are more than a nuisance — they’re a sign your sealed units might be failing. Here’s what you need to know and how to fix the problem in Winnipeg’s extreme climate.
Why Do Windows Fog Up?
1. Inside Surface Condensation (Interior Fog)
This occurs when warm, moist indoor air hits a cold window surface. Common causes:- Poor ventilation
- High humidity from showers, cooking, etc.
- Old or inefficient windows
2. Outside Surface Condensation (Exterior Fog)
Usually seen in the mornings during warmer seasons. This is normal and happens when energy-efficient glass stays cooler than the outdoor air.3. Between-the-Glass Condensation (Sealed Unit Failure)
If you see fog between the panes, it’s a clear sign of sealed unit failure. In Winnipeg’s climate, this is a very common issue in windows 10+ years old.Why You Shouldn’t Ignore It
Reduced insulation — leads to higher energy bills- Risk of mold or mildew growth
- Decreased home value and poor curb appeal
- Potential damage to window frames
