Why Do Windows Get Foggy?
That hazy, milky appearance between your window panes isn't dirt you can wipe away—it's a failed seal. Modern double and triple-pane windows (called insulated glass units or IGUs) are sealed with an airtight barrier filled with inert gas like argon. When that seal fails, moisture gets in and you see fog, condensation, or even water droplets trapped between the glass.
In Ottawa's climate, with extreme temperature swings from -30°C winters to +30°C summers, window seals work hard. Over time, the constant expansion and contraction can cause seals to break down. This is especially common in windows that are 10-20 years old.
The Good News: You Don't Need New Windows
Here's what most homeowners don't realize: in most cases, we can replace just the glass—not the entire window frame. This approach, called sealed unit replacement, offers significant advantages:
- Save 50-70% compared to full window replacement
- Keep your existing frames (especially important for wood or heritage windows)
- No exterior or interior trim work required
- Faster installation—often completed in one visit
- New energy-efficient glass with fresh warranty
- Upgrade to Low-E or triple-pane while you're at it
When We Recommend Full Replacement
We'll always give you an honest assessment. Sometimes the frame itself is the problem—warped vinyl, rotting wood, or damaged aluminum. In those cases, replacing just the glass won't solve your issues. We'll explain your options clearly and never push unnecessary work.
Our approach is simple: repair what can be repaired, replace what needs replacing. We've been doing this for 55+ years, and our reputation depends on giving you the right advice—not the most expensive solution.
