Sliding Glass Door Repair in Raleigh, NC
A patio door that takes two hands, jumps the track or won't lock is riding on two worn rollers the size of a coin — not a dead door. Rollers rebuilt from $475, track and lock tuned, gliding one-handed in one visit.

What Actually Failed
Why a Ten-Year-Old Patio Door Already Drags
Plenty of Raleigh patio doors start dragging while the house still feels new. The door isn't worn out. The two small rollers that carry it are.
What's inside a roller. A small wheel spinning on a ball bearing, held by an axle pin in a housing at the bottom of the door. The whole panel rides on two of them. They sit right in the track, where rain, pollen, grit and sand collect, so they wear faster than anything else on the door.
How a sliding door roller fails Three side views of a roller on its track. One: water and grit collect in the track and get into the roller, while the door still rolls. Two: the bearing rusts, its balls fall out and the wheel grinds instead of spinning. Three: the axle pin breaks, the wheel drops out of place and the bottom of the door sits on the track and drags.
How they fail. The bearing rusts and the balls fall out, so the wheel grinds instead of turning. Or the axle pin breaks, the wheel drops out of place, and the door sits down on the track. Either way the door drags, and the lock stops lining up.
What you can try. The adjustment screws are in the bottom corners of the panel, going into the side of each roller housing. Clockwise lifts the door, counterclockwise lowers it. If the door glides again, no visit needed.
What we do. If adjusting doesn't help, we replace the rollers, clean and straighten the track and set the door so it glides and locks, from $475 ($535 with new wheels). The panel, the glass and the frame stay.

Rollers, Not Doors
Builder-Grade Rollers
Why Do Raleigh's Newer Patio Doors Drag After Only Ten Years?
Brier Creek, Wakefield, the North Hills rebuilds — Raleigh's boom houses got production sliders with the lightest rollers the builder could spec. Ten years of a family going in and out to the deck and the nylon wheels are square. The door is young and the glass is perfect; only the rollers gave out. Heavy-duty steel rollers from $475 put a better glide under the door than it ever had new.

The Replacement Pitch
They Quoted a New Slider — Did You Just Need Two Wheels?
Door companies sell doors, so a dragging slider in Raleigh 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.

“I have three kids, and they accidentally broke the tempered glass on our door. I contacted WowFix, but I had to wait for weeks for a technician. Despite the wait, I can't complain because they offered a reasonable price, and their technician did an excellent job replacing the glass.”

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.
