What Actually Failed
The Same Parts, the Same Age: Find Yours
Katy's master-plans got the same window hardware section after section, and it's retiring together: balances, latches, weatherstripping. Tap what your window is doing:
What is your window doing?
Diagnosis
The sealed glass unit
The seal around the edge of the glass opened. Moisture got in and filled the drying beads inside the unit like a bathtub. When the tub overflowed, the fog showed up on the inside of the glass, where no cloth can reach.
We swap just the glass unit in your frame, from $198.
How foggy glass gets fixed →Diagnosis
The pivot shoe, a small plastic part
Hidden springs in the sides of the frame hold the sash up through a plastic pivot shoe. Over the years the plastic dries out and its hook breaks off, so nothing holds the sash anymore. Sometimes a sash that was forced snaps its metal pivot pin instead.
New balances and shoes, $175 a window.
Why windows won't stay up →Diagnosis
The bottom of the sash and the sill
Paint is the only armor wood has. Once it cracks, rain soaks into the flat parts at the bottom and never dries, and a fungus turns the wood soft from the inside. The top of the window stays solid.
We cut out the rot and splice in new wood: a sash from $375, a sill from $475.
How rot starts and how we fix it →Diagnosis
The crank operator, a small gearbox
On a casement window, a little gearbox under the sash turns the handle into motion. Its teeth strip with age, or all at once when a stuck window gets cranked hard. The handle spins free and the window stays put.
A new operator bolts in, $275.
More on broken cranks →Diagnosis
The weatherstripping
The soft strip around the sash flattens with age and stops touching it, so air walks right through the gap. A worn latch that no longer pulls the sash tight makes it worse.
New weatherstripping, $115 a window (3 windows minimum).
How we seal drafty windows →Diagnosis
Just the glass
A stray ball, a stone from the mower, a hard knock. The glass broke; the frame and the sash didn't.
New glass in your frame: a single pane from $164, a double-pane unit from $198.
Glass repair, every type →Diagnosis
The screen: its mesh, or its frame
Sun slowly breaks down the coating on the mesh until the strands snap instead of flexing, and it tears. Press it gently with your thumb: springy mesh only needs a wash, stiff papery mesh is done. Then look at the frame.
Frame still straight
Rescreen: new mesh in your frame

Diagnosis
The sash lock
The lock on the middle rail pulls the two sashes together. When it wears out, or the sash settles a little low, the two halves no longer meet and the window won't lock.
A new lock, $115.

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 $475. One company, one written sheet — and the $1,000+ per-opening replacement pitch stays outside.

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.
