Foggy Window Repair in Katy, TX
That permanent white haze inside your double-pane glass is a seal the Texas sun tore open — not a window that needs replacing. We fabricate a fresh insulated glass unit sized to your opening — rigid spacers, desiccant and a dual-seal edge rated for this heat — and exchange the glass alone, from $198, under a written 5-year warranty.

The Seal Died, Not the Window
The Prairie Has No Shade
Katy's Master-Plans Were Glazed Together — Now They're Fogging Together
Katy grew the way few suburbs anywhere did: Cinco Ranch broke ground in the early '90s, then Grand Lakes, Seven Meadows and Firethorne filled the prairie through the 2000s — thousands of homes per community, glazed from the same builder pallets in the same construction seasons. Out here that matters more than it would closer to town, because the Katy prairie is flat and young: the live oaks planted with those subdivisions still don't shade a second-story window at 4 p.m. So every west- and southwest-facing pane takes the full force of a summer like 2023 — 45 days at 100°F or hotter — bowing outward in the afternoon bake and pulling flat again at night. That daily flexing works the factory edge seal like a paperclip until it tears; then Gulf-loaded air slips into the cavity, condenses on the cooler inner pane, and the cloudiness never leaves. When one cul-de-sac's glass carries one birth year, the failures arrive the same way the houses did: street by street.
-
Sun-hammered west elevations with no mature shade fail first
-
Haze or beads of water trapped where no rag can reach
-
Whole '90s-2000s sections reaching seal-failure age at once
-
Builder-grade sealed units were never rated for prairie sun
What Nobody Tells Katy
The Fog Lives in a $198 Part — Not in a $1,000+ Window
Most Katy homeowners hear one number for fogged glass, and it starts with a comma. Here's what the replacement pitch leaves out: the haze is confined to a factory-sealed glass sandwich, and that sandwich is a manufactured part we can build again. Your frame, sash, trim, brick and HOA-approved exterior stay exactly as they are. We take the dead unit's dimensions to the millimeter, then fabricate its successor for this climate specifically — rigid spacers that absorb the daily expansion, a desiccant-packed perimeter that starves the cavity of moisture, and a dual-seal edge engineered for triple-digit summers. The clear unit drops into your existing sash in a single visit, backed by a written 5-year warranty. From the sidewalk, nothing changed — except you can see through the window again.

The Process
How Foggy Window Repair Works in Katy
The new glass exists before we knock — one firm-dated stop and the haze is history.
01/Count the Hazed Panes
Book online or call with the tally of clouded glass. Dispatch slots you onto a scheduled west-Houston route with a firm appointment date — never a vague multi-day window.
02/Confirm & Measure
First we rule out surface condensation and prove the seal itself has died; then the opening's exact dimensions and spacer go on paper right next to your written price.
03/Fabricate for the Climate
Assembly happens around a stiff spacer frame, a moisture-hungry desiccant fill and a doubled edge seal chosen for the sun your wall actually takes.
04/Exchange, Seal & Warranty
Old unit out, new unit bedded in fresh sealant, inspected with you in daylight — the whole job under a 5-year written workmanship warranty.
Transparent Pricing
How Much Does Foggy Window Repair Cost in Katy?
A fogged-unit exchange in Katy starts at $198 per insulated glass unit — the figure comes off a printed catalog and lands on paper before a single cut is made. What moves it:
- Base — glass-only sealed-unit exchange from $198
- Size — the tall two-story panes of the 2000s cost more glass
- Glass type — Low-E coatings, tempering and tint add cost
- For scale — full window replacement starts at $1,000+ per opening

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.

Foggy Window Repair in Katy — FAQ
It's the master-plan effect. Your section was built in one push, glazed from the same pallets of builder-grade sealed units, and every one of those seals has been aging under the identical prairie sun since. When the first unit lets go, its siblings across the street are running the same clock. The good news scales the same way: each fogged unit is an individual from-$198 exchange, and one scheduled visit can clear several houses' worth of glass on the same route day.
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.
