A Gearbox, Not a Window
It's a Part
Crank Spins But the Window Won't Move? That's the Operator
Inside the casement sill sits a small gearbox — the operator. Its teeth strip with age, or all at once when a painted-shut window gets cranked hard. The handle spins free, the window sits still, and the fix is a bolt-on part from $275. The glass, sash and hinges never enter the conversation.
-

Stripped, grinding or seized — same part, same price

Stuck OPEN with weather coming? Same-day securing
The $1,400 Handle
"Discontinued Brand" Is Not a $1,400 Problem
Window sellers match parts by logo; when the logo is gone, the answer becomes a new window. Operators actually match by size, hinge side and arm type — so we fit discontinued brands weekly. The quote for a whole new window over a handle is the one to laugh at politely and decline.

Matched by size and type — logos irrelevant

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.

See It For Yourself
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.
Window Cranks — FAQ
We do — that's a same-day call. We close and secure the sash first so the weather stays outside, then fit the new operator so it cranks like day one. Storm beaten, window fixed.
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, Same-Day Secure
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.
