Most homeowners don’t think about their windows until something goes wrong — a foggy panel, a cold draft, or a sudden crack that spreads across the glass. But in the Central Valley, where temperatures swing from chilly winter mornings to warm afternoons, dual-pane window failure is extremely common.
At GlassPro, we replace hundreds of failed dual-pane windows every year in Fresno, Clovis, Selma, Kingsburg, Fowler, and Friant. And almost every homeowner asks the same thing:
“Why did this happen?”
A Homeowner Story From Northeast Fresno
A homeowner in Northeast Fresno recently called us after noticing a “cloudy circle” in her master bedroom window. Within weeks, the entire glass panel looked like someone smeared lotion across it. She could barely see outside.
What happened?
The seal between the panes had failed, letting moisture leak inside. Heat from the sun expanded that moisture, causing permanent fogging and lowering the window’s insulation power.
Once the seal is gone — the window can’t be repaired. It must be replaced.
How to Know Your Dual-Pane Window Is Failing
Here are the most common early-warning signs:
-
Fogging or moisture inside the glass
-
Milky or cloudy appearance
-
Small beads of water between the panes
-
Drafts even when the window is fully closed
-
Glass feels cold on the inside surface
-
Cracks forming near the corners
If you live in Fresno or Clovis, the sun exposure from the south and west sides of your home accelerates seal failure. In Kingsburg and Selma, agricultural dust often settles into window seals, causing faster deterioration.
Why Dual-Pane Windows Fail
-
UV exposure
-
Age (10–20 years is normal lifespan)
-
Poor installation
-
Pressure changes from weather
-
Frame expansion and contraction
-
Heavy temperature swings
