Sliding Glass Door Repair in Greensboro, NC

Rollers, Not Doors
Thirty-Year Sliders
Why Are Greensboro's Original Patio Doors Still Worth Fixing?
Irving Park and Starmount houses came with aluminum and early-vinyl sliders that are now thirty years old — heavy, well-built, and rolling on wheels that turned to flat spots a decade ago. The panel and the tempered glass are fine; the door-company answer is still 'replace it.' Ours is heavy-duty rollers from $475, a straightened track, and the door your house was built with gliding one-handed again.
-
Heavy-duty rollers fitted and adjusted — from $475 ($535 with new wheels)
-
Track cleaned, straightened or replaced — $475
-
Sliding door lock $175 · latch $115 · weatherstripping $175
-
Foggy or broken slider glass — tempered units from $198
The Replacement Pitch
They Quoted a New Slider — Did You Just Need Two Wheels?
Door companies sell doors, so a dragging slider in Greensboro turns into a $2,500–$4,500 replacement conversation. The honest math: new rollers and a tuned track from $475, one visit, and the door your house came with glides like the day it was hung. Your glass, your frame, your money — all staying put. If a panel is truly finished, we'll say so in writing before anyone spends real money.

-
Any brand, including discontinued panels — matched by wheel and load, not logo

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.

Sliding Glass Door Repair in Greensboro — FAQ
Yes — rollers are matched by wheel diameter, housing and load, not by the sticker on the frame. Discontinued Triad sliders are most of what we see; the truck carries the common patterns and the rest we source. Repair from $475 either way.
Before We Arrive
How to Prepare for Your WowFix Door Repair Visit
- 1
Photograph the door and the problem spot
Take one photo of the whole door and a close-up of the trouble area — the track, the handle, the glass, or the soft wood at the bottom. It lets us quote faster and bring the right parts.
- 2
Note what the door is doing wrong
Jot down the symptom — grinds or sticks on the track, won't lock or latch, drafts around the edges, fog or cracks in the glass, soft flaking wood at the bottom. It tells us whether it's hardware, a glass-only swap (from $198), or wood work.
- 3
Clear the doorway and a few feet on each side
Move mats, planters and furniture back from both sides of the door — most door work happens from inside and outside at once, and a clear opening keeps the visit quick.
- 4
Find any brand sticker or paperwork
Door brands hide their stickers on the edge or hinge side. If you spot one — or still have install paperwork — set it aside. Not required, but it helps us match rollers, locks and glass on the first trip.
- 5
Make sure we can reach the outside of the door
Unlock gates, secure pets, and clear the deck or patio path. With access to both faces of the door, nearly every repair finishes in a single 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
