Moisture between your window panes? Foggy or cloudy glass? This means your double pane window seal has failed. We replace the entire insulated glass unit to restore clarity and energy efficiency.
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.
Seals typically last 15-20 years before breaking down
Sunlight breaks down seal materials over time
Hot/cold expansion and contraction stresses seals
Rain and humidity accelerate seal degradation
Replace just the insulated glass unit (IGU) while keeping your existing window frames. Most cost-effective option.
Windows with good frames, vinyl or wood windows under 20 years old
Replace the entire window including frame, sash, and glass. Best long-term solution if frames are damaged or very old.
Old windows (20+ years), damaged frames, or when upgrading entire home
We'll inspect your windows and recommend the most cost-effective solution
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:
Double pane windows are factory-sealed in a controlled environment. The seal cannot be recreated in the field.
Once moisture gets in, it etches the Low-E coating and leaves permanent mineral deposits on the glass.
The desiccant inside the spacer bar is saturated and can no longer absorb moisture.
We replace the entire insulated glass unit (IGU) with a brand new, factory-sealed unit that will last for years.
We measure your existing window opening precisely - width, height, and thickness
We order a custom-made insulated glass unit with Low-E coating and argon gas fill
When the new IGU arrives, we carefully remove the old foggy unit from your window frame
We install the new IGU with proper glazing beads and weather seal for a perfect fit
Brand new glass means perfect clarity - no more foggy or milky appearance
New Low-E coating and argon gas reduces energy bills and improves comfort
Clear, efficient windows improve curb appeal and home value
IGU replacement is much more affordable than full window replacement. Here's what affects the price:
Larger windows cost more due to glass size
Low-E, tempered, or specialty glass affects price
Some manufacturers require specific IGU specs
Multiple window discounts available
Good news: IGU replacement is typically 50-70% less expensive than full window replacement!
