Glass Swaps, Door Stays
Broken or Foggy
Baseball Through It or Fogged Over — Is It the Same Repair?
A shattered slider gets a new tempered unit — built to your exact size, rated to code — set into the same panel. A foggy slider is the identical swap without the broken glass. Either way the door you own stays on its track.
- built to size — from $198
Tempered safety glass
-
Broken glass rebuilt tempered, to code
-
Foggy slider units — same swap, save ~70% vs a new door
-
French and entry door glass — same repair, same visit
The $3,000 Quote
Why Does Their Quote Say "New Door" and Ours Doesn't?
Door companies start at the showroom: $2,500–$4,500 for a new slider, weeks of lead time, a construction day in your kitchen. We start at the part that failed: one glass panel, from $198, installed clean. The most marked-up "replacement" in the industry is the easiest repair in ours.

The Process
How Patio Door Glass Replacement Works
Secure today, measure once, swap clean.
01/Secure First
Broken glass cleared and the opening made safe on the visit.
02/Measured Exact
The panel is measured to the millimeter; tempered units must fit, not almost-fit.
03/Built to Code
Door glass is safety-rated — your unit is fabricated tempered, to spec.
04/Swapped Clean
Old unit out, new unit sealed in, track and rollers checked on the way — warrantied.
Transparent Pricing

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.

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.
Patio Door Glass — FAQ
Call us and we book the visit. Until then, tape heavy plastic or cardboard over the opening and keep kids and pets away. On the visit we clear the glass, seal the opening and measure it; the new tempered unit is heat-treated to size and installed on the return visit.
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.

The Rot Comes Out, Not the Window
We fabricate an exact-profile piece from laminated lumber and splice it in.
Shattered Pane, Made Safe & Reglazed
New glass built to the window's exact size — frame and trim untouched.
Broken Glass on a Brick Ranch
The pane is the part that failed — so the pane is the part we replace.
Fog That Won't Wipe Off
A failed seal, not a failed window: the sealed unit is swapped, the frame stays.
Patio Door Saved from the Landfill
Rotted bottom rebuilt on-site — a fraction of the ~$10,000 a new door runs.
