Frame Solid? Repair Wins.
The Honest Test
Does This Window Actually Need Replacing?
Here's the test every Charlotte replacement salesman skips: is the FRAME solid? Fogged glass is a $198 unit swap. A sash that won't stay up is a $175 balancer. A rotted sill is a $475 wood rebuild — even 'repair rotted window sill' searches usually end far from a new window. Replacement earns its price in a handful of real cases, and we name them below.
-
Frame rot past saving — structure, not surface
-
Frames racked out of square by settling
-
Single-pane originals you want upgraded whole
-
Storm or impact damage beyond the sash
When Replacement Wins
Then It's Worth Doing Properly — Once
A replacement window is only as good as its installation: measured to the true opening, flashed against Carolina rain, insulated at the shims, sealed inside and out. We install replacement windows across Charlotte for every brand and style — Simonton and other vinyl lines included — with the same written-quote honesty as our repairs.

True-opening measurements, brand and style options that fit your home and budget — no upselling to the premium line by default.
03/Install, Flash, Seal
Old unit out, new window set square, flashed against water, foamed at the shims, sealed inside and out.
04/Walkthrough & Warranty
We cycle the window with you, check the seal lines, and hand over the written workmanship warranty.

“I had a good experience with WowFix when they came out to provide an estimate for my front door. He was very nice, took the time to discuss the issue with me, and provided an estimate without pressuring me to make a decision on the spot. He was understanding and gave me time to think things over before moving forward. I appreciate his time and professionalism!”

“Wanted to wait until I had the door painted. Eugene did a fantastic job tearing out the entire frame down to the brick mold due to wood rot. He basically rebuilt the entire thing along with the wood rot on the door itself. He does work some unconventional hours but the craftsmanship was worth it.”

“Excellent service. Eugene was super helpful, and found out the replacement rollers for our 20 year old patio glass door ( the original company has discontinued the product). The door works fine. He also helped me in adjust the screen door.”

Window Replacement in Charlotte — FAQ
We price both paths on one sheet. The assessment checks frame, sash, glass and hardware; if a $198 glass swap or a $475 sill rebuild solves it, that's on the quote next to the replacement number. Charlotte homeowners pick with real numbers — that's the whole difference.
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.
