It's Inside the Sandwich
The Physics
Why Double-Pane Windows Fog Up — and Why Cleaning Can't Help
A double-pane unit is two sheets of glass sealed around a spacer, with dry air or gas in between and desiccant standing guard against moisture. Seals age; humidity swings pump damp air past the tired seal on every pressure change; the desiccant fills up — and one morning the fog is inside the sandwich, on the one surface no cloth can reach. That's the whole disease. The window around it is usually in perfect health.
-
Fog lives BETWEEN the panes — cleaning is physically impossible
-
Early sign: haze that comes and goes with the weather
-
Late sign: permanent milkiness and mineral streaks
-
The frame, sash and hardware are innocent bystanders
Built, Not Bought
We Manufacture the Replacement Units — That's Why the Fog Stays Gone
Most glass companies order replacement units from a distributor and inherit whatever seal quality arrives. We build ours: rigid aluminum spacers that hold their geometry, fresh desiccant, quality butyl sealing — fabricated to your window's exact measurements, tempered or Low-E where the opening calls for it. Your frame stays on the wall; only the glass sandwich changes. It's the difference between fog gone for a warranty period and fog gone for good.
-
Rigid aluminum spacers — not soft foam that warps
-
Fresh desiccant and butyl seals in every unit
-
Low-E, tempered and tinted options matched to your glass
-
From $198 per unit vs $1,000+ per replacement window

Eugene fabricated both screens and new half double-pane windows for my home. He was professional, dedicated, and experienced. He went above and beyond to ensure the job was done right and in a timely manner. I would highly recommend WowFix for work that meets all expectations!

I had a fantastic experience with WowFix. They repaired my existing windows by cutting out rotted sashes, fashioning new ones on-site, and splicing them in. They look and work absolutely good as new!

WowFix is a great company for repairs on doors and windows. I had two rotten double-door frames that they rebuilt. They communicate well and the pricing was fair.

A Real WowFix Repair — Start to Finish
No stock footage, no actors — this is one of our actual jobs. Watch a rotted, fogged-out window brought back to flawless, like-new glass.
Foggy Windows — FAQ
Yes — that's the entire service. The fog is inside the sealed glass unit, and the unit is a replaceable part. We build a new one to your window's measurements and swap it into the existing frame. Every company that says otherwise sells windows for a living.
Before We Arrive
How to Prepare for Your WowFix Window Repair Visit
- 1
Photograph each problem window in daylight
Snap a clear photo of every foggy, cracked or stuck window in natural light. Morning light shows fog between the panes best and lets us quote faster — often before we arrive.
- 2
Note what each window is doing wrong
Jot down the symptom per window — fog between the glass, won't open or stay up, draft, cracked pane, or rotted frame. It tells us whether it's a glass-only swap (from $198) or hardware/wood work.
- 3
Clear about three feet in front of each window
Move furniture, blinds and décor back roughly three feet so our crew can measure and work safely. It keeps the visit quick and your things out of the way.
- 4
Find any window brand or paperwork
If you have the original window brand, a sticker in the frame, or install paperwork, set it aside. It's not required, but it helps us match glass and parts on the first trip.
- 5
Make sure we can reach the windows outside
Unlock gates, secure pets, and clear the exterior path to the windows. Most glass-unit work is done from both sides, so outside access keeps everything one visit.
