A Frame Question
The Honest Test
Replacement Is a Frame Question — Nothing Else Qualifies
Fogged glass is a $198 unit swap. A dropping sash is a $175 balancer. A rotted sill is a $375 wood rebuild. None of those is a replacement case, whatever the salesman said. Replacement earns its five-figure whole-house bills only when the FRAME is finished: rot through the structure, openings racked out of square by settling, storm damage past the sash, or single-pane originals you've decided to upgrade wholesale. Our estimate walks that test in front of you — both columns, one sheet.
-
Frame rot through the structure — honest replacement
-
Openings racked out of square — honest replacement
-
Fog, hardware, sill rot — repairs, and priced as such

Installed Like We Repair
Replacement Windows Live or Die by the Installing Hands
We spend our weeks repairing other installers' shortcuts, which makes our install spec non-negotiable: true-opening measurement, square shimming at the load points, flashing lapped to shed Carolina rain outward, low-expansion foam at the gaps, sealed inside and out, hardware cycled before we leave. Every brand and style — quality double-hungs with tilt-in sashes and Low-E as the baseline, not the upsell. Openings are never left unsecured overnight.

Measured, shimmed, flashed, foamed, sealed — every time

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.
Window Replacement — FAQ
Apply the frame test: if the frame is sound, everything else — fog, drops, drafts, sill rot — is a repair at a fraction of replacement cost. If frames are rotted through, racked or storm-crushed, replacement is honest. Our free estimate runs the test window by window and shows both columns.
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.

Real WowFix Repairs, Up Close
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.
Patio Door Saved from the Landfill
Rotted bottom rebuilt on-site — a fraction of the ~$10,000 a new door runs.
