The Builder-Balance Epidemic
Every Master-Plan Section Got the Same Hardware — and It's Retiring Together
Between the mid-'90s and 2008, Katy's builders raised entire villages at a time — Cinco Ranch alone runs to many thousands of homes, with Grand Lakes, Seven Meadows and Firethorne racing alongside — and they bought window hardware the way they bought shingles: by the identical mid-market pallet. Twenty-plus years later that procurement decision is your maintenance calendar. Spiral balances lose their spring temper faster in frames that bake at 100°F; vinyl latches turn chalky and brittle under prairie sun; two decades of A/C-season heat cycling flatten the weatherstrip that once sealed the sash. When your kitchen window starts free-falling, it isn't your house failing — it's a parts generation aging out, on schedule, across your entire section. And every one of those parts has a line in our printed catalog.

The Wedge
One Route Stop, the Whole Punch List — Built for Commuter Calendars
Half of Katy leaves for the Energy Corridor before seven and gets home after six — nobody here has spare weekdays to burn shepherding a parade of contractors. So we compress the job into one firm-dated visit that works the entire house: the stop that saves the free-falling kitchen sash also re-springs the tired balances upstairs, replaces chalky latches in every bedroom, and renews the weatherstrip your summer bill escapes through — all at catalog prices under a single trip charge. When the walk-through turns up a specialist's problem, it hands off cleanly instead of upselling: haze sealed inside the glass goes to a from-$198 unit exchange, a hail-cracked pane to made-to-measure glass from $198, a soft sill to a real-wood rebuild from $375. One company, one written sheet — and the $1,000+ per-opening replacement pitch stays outside.

The Process
How Window Repair Works in Katy
Write the list, get a date, watch it die in one visit — warrantied in writing.
01/Walk the House, Note Every Symptom
Slams shut, won't lock, whistles, fogs over, feels spongy — describe it however you like; each complaint lands on a numbered catalog line.
02/Lock In a Route Date
Your west-Houston appointment gets booked ahead with a firm date, and the truck loads against your exact list — hardware by spec, glass pre-built when the list calls for it.
03/Work the Whole List
Room by room: balances re-sprung, latches and locks swapped, cranks replaced, weatherstrip laid — each item a printed-catalog line on a single sheet.
04/Cycle, Lock & Warranty
You watch every serviced window cycle and lock before the truck pulls away — and the full visit is covered by 5 years of written workmanship warranty.

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.

Window Repair in Katy — FAQ
Because they were born together. Your section's windows came off the same builder pallet with the same spiral balances inside, and those springs have been fatiguing under the same attic-side heat ever since — so they retire as a group, not one by one. Prop the dangerous ones closed until service (a free-falling sash is a finger-breaker), and have the set re-sprung at $175 per window in one scheduled stop.
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.
