Why Do Windows Get Foggy?

Double pane windows have a seal around the edge that creates an airtight space between the two panes. When this seal fails, moisture gets in and causes fogging. Unfortunately, once the seal fails, it cannot be repaired - the entire insulated glass unit (IGU) must be replaced.

Common Causes of Seal Failure:

Age & Wear

Seals typically last 15-20 years before breaking down

UV Damage

Sunlight breaks down seal materials over time

Temperature Cycles

Hot/cold expansion and contraction stresses seals

Water Exposure

Rain and humidity accelerate seal degradation

Foggy Window Replacement Options

Glass-Only Replacement

Replace just the insulated glass unit (IGU) while keeping your existing window frames. Most cost-effective option.

  • Typically 40-60% less expensive than full window replacement
  • Works if frames are in good condition
  • New Low-E, argon-filled glass available
  • 1-2 week turnaround typically
Best For:

Windows with good frames, vinyl or wood windows under 20 years old

Full Window Replacement

Replace the entire window including frame, sash, and glass. Best long-term solution if frames are damaged or very old.

  • Modern energy-efficient windows
  • Improved operation and sealing
  • Better warranties on new windows
  • Higher upfront cost, better long-term value
Best For:

Old windows (20+ years), damaged frames, or when upgrading entire home

Why Can't You Just "Fix the Seal"?

We get this question all the time. Unfortunately, once a double pane window seal fails and moisture gets between the panes, there's no way to repair it. Here's why:

The Seal Can't Be Re-done

Double pane windows are factory-sealed in a controlled environment. The seal cannot be recreated in the field.

Moisture Has Damaged the Coating

Once moisture gets in, it etches the Low-E coating and leaves permanent mineral deposits on the glass.

The Spacer is Compromised

The desiccant inside the spacer bar is saturated and can no longer absorb moisture.

The Solution: IGU Replacement

We replace the entire insulated glass unit (IGU) with a brand new, factory-sealed unit that will last for years.
