WowFix vs Argo Glass & Windows
Argo Glass & Windows is Charlotte's best-reviewed window repair shop besides us — and the comparison comes down to precision. Argo publishes price ranges (sash repairs $50–$500, sill restoration $400–$700, per their site, August 2026). WowFix publishes exact prices: sills $475 flat, glass units from $198 — fabricated in our own shop rather than ordered from a glass manufacturer.

The Exact Number
Ranges vs Numbers
A $50–$500 Range Is Not a Price
Argo deserves credit for publishing anything at all — most competitors publish nothing. But look at the spread on their Charlotte page (August 2026): sash repairs $50–$500, window sash work $200–$700, sill restoration $400–$700, hardware $20–$450. A 10x range means the real number still arrives with the visit. WowFix prices the part, not the suspense: sills rebuilt $475, balances $175, hardware from $115, sealed glass units from $198 — the same numbers our phone team and this website quote.
-
WowFix rotted sill: $475 flat · Argo: $400–$700 range
-
WowFix hardware: from $115 exact · Argo: $20–$450 range
-
WowFix glass unit: from $198 · Argo: quoted per job
-
Both: strong local reviews and real repair-first culture — this is a close race
Where the Glass Comes From
Own Shop vs Certified Dealer
Argo describes itself as a certified Cardinal IGU dealer installing factory-sealed units with a 20-year glass warranty — a legitimate, quality supply chain. WowFix fabricates insulated glass units in our own shop instead: no ordering cycle, one-visit swaps, and a 5-year warranty that covers parts AND labor. Note the difference in warranty types: a manufacturer's glass warranty covers the sealed unit itself; our written warranty covers the unit and the work. Ask both companies to put the scope on paper — we already do.
-
WowFix: own-shop fabrication — measure, build, install in one visit
-
Argo: Cardinal-manufactured units — factory glass, dealer install
-
Warranties differ in kind: manufacturer glass warranty vs parts-and-labor in writing

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!

This is a great company. We appreciate the hard work and honesty of Eugene, who made sure our windows were fixed to our satisfaction. He completed the work on time as promised.

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.

WowFix vs Argo — Honest FAQ
Genuinely yes — excellent reviews and a real repair-first approach, which is rare. That's exactly why the comparison is worth making carefully: the differences are precision (exact prices vs ranges), glass supply (our own shop vs Cardinal-manufactured units) and warranty type (our 5-year parts-and-labor vs a manufacturer glass warranty).
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.
