Foggy Window Repair & Sealed Unit Replacement in Edmonton
We replace cloudy, moisture-filled, and condensation-trapped double and triple pane sealed glass units across Edmonton, Sherwood Park, and St. Albert. Keep your window frame, restore clear views, and can cost less than full window replacement, depending on the project.
Quick Answer: Can foggy windows be repaired?
Yes. Foggy windows or condensation between panes are caused by a broken perimeter seal in the insulated glass unit (IGU). Instead of replacing the entire window frame, Window Tune-Up Co. installs factory-new, Edmonton-manufactured glass units inside your existing frames—restoring full clarity permanently.

Understanding failed window seals in Edmonton climates
Extreme seasonal temperature shifts cause window glass to expand and contract, eventually breaking the perimeter seal of Insulated Glass Units (IGU). Once broken, moist Edmonton air enters between the panes, trapping fog and mineral deposits that cannot be wiped off.
* Typical pricing; actual cost varies by size, glass specification, hardware and installation requirements.
Why "Defogging" Drills Don't Work Long-Term
Drilling small holes or spraying chemicals inside failed glass units only temporarily removes visible moisture. It does not restore lost Argon insulating gas or fix the broken seal, allowing cold air to bleed into your home. Replacing the sealed unit completely addresses the failed sealed unit.
High Thermal Performance Standard
Every replacement sealed unit includes microscopic silver Low-E coatings and high-density Argon gas insulation as standard, designed to improve thermal performance when the selected glass specification is appropriate.

Everything you need to know about foggy window repair
Can you clean the fog out from between the glass?
No. Once moisture enters between the panes, mineral deposits etch into the glass. "Defogging" methods that drill small holes into the glass do not restore lost Argon gas or fix the broken seal. Replacing the sealed unit completely is a complete sealed-unit replacement is the standard repair approach. Check out our Broken Glass & Board-Ups page if your glass is shattered.
