Secured Same Day
When Glass Can't Wait
A Broken Storefront Can't Wait Until Next Week
Cracked or shattered storefront glass is a security problem first and a repair second. We secure the opening the same day — cleanly, not scrap plywood — then fabricate the measured tempered or insulated unit on our bench and install it within days. The store stays open, the paperwork stays clean, and nobody pushes you toward a full framing job you don't need.
-
Openings secured same-day, cleanly
-
Tempered and insulated units fabricated to measure
-
Installed within days — one written price for the whole arc
-
Board-up to final glass: one crew, one invoice
Hardware Under Load
Commercial Doors Take a Beating — Fix the Part, Keep the Door
A commercial entrance cycles more in a week than a home door does in a year. Closers wear out, panic bars stop latching, pivots drag, sweeps shred — and every one of those is a component with its own fix, not a reason to replace the door. We diagnose the failed part, quote it in writing, and swap it like-for-like.
-
Closers and panic bars serviced or swapped
-
Pivots, hinges and sweeps — fixed at the part level
-
Commercial glass doors re-glazed to code
-
Written quote before any work starts

The Process
How Commercial Repair Services Works
Secure, quote, repair, warranty — with paperwork your books can use.
01/Site Visit & Securing
We come to the property, make broken glass or a failed door safe the same day, and identify exactly which component failed.
02/Written Quote
One clear price on paper — the kind a property manager or owner can file, compare and approve without surprises.
03/The Repair
Glass fabricated to size on our bench, hardware swapped like-for-like — installed by our own crew, not subcontractors.
04/Test & Warranty
Doors cycled, glass inspected with you, and the work backed by a written workmanship warranty.
Transparent Pricing
How Much Do Commercial Repairs Cost?
Every commercial job is quoted on-site, in writing, before any work begins — the estimate is free. The number depends on:
- Scope — a cracked pane, a dragging door and a failed closer are three different repairs
- Glass type & code — tempered and insulated storefront units cost more than annealed
- Size — storefront panes run big; material and handling scale with them
- Access & timing — ground-floor swaps go faster than high or awkward openings

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.

A Real WowFix Repair — Start to Finish
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.
Commercial Repair Questions, Answered Straight
Same day. We make the opening safe and weather-tight first — cleanly, not scrap plywood — then measure, fabricate the replacement unit on our bench and install it within days. One written price covers the whole arc.
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.
Proof
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.
