A sliding glass door that drags, jumps the track or won't lock is one of the most common calls we get from Raleigh, Cary and Wake Forest homeowners. It's also one of the most fixable. In most homes the glass panel and frame are fine; the trouble is in the parts you can't see: the rollers under the panel, the track they ride on, or a latch that no longer lines up. Our Raleigh door repair craftsmen check those first, because a repair usually costs far less time than a new door. Here's how to tell what's going on with yours.
Why is my sliding glass door so hard to open?
Usually one of four things:
- Worn or broken rollers. Each panel rides on two small roller assemblies. When the wheels wear flat or the bearings fail, the panel scrapes the track instead of rolling.
- A dirty or damaged track. Grit, pet hair and leaves pack into the track, and a dented or worn track ridge makes the door bump and stick.
- A panel that has dropped out of adjustment. Most rollers have an adjustment screw. As the house settles, the panel can sit too low and drag.
- Weather and humidity. Raleigh summers swell wood-clad frames, and a bent screen door or a sagging header can pinch the panel.
What sliding door problems can be repaired?
- Cleaning and vacuuming the track
- Adjusting the rollers to level the door so it glides smoothly and closes evenly against the frame
- Replacing worn rollers with matching assemblies
- Repairing or capping a worn track
- Replacing the handle, latch or keeper, or adding a secondary lock
- Replacing worn weatherstripping and the bottom seal
- Re-hanging or replacing a bent screen door
Repairs on French doors and hinged patio doors are similar: hinge adjustment, a new strike or astragal, and new seals. If your patio door won't latch, our guide to doors that won't latch or let in drafts walks through the hinge and strike-plate fixes.

When should you replace a sliding glass door instead?
Repair stops making sense when the door itself has failed:
- Fog or moisture between the glass panes. The insulated glass seal has failed. We'll tell you whether that panel or the whole unit needs replacing.
- A rotted or soft sill or frame, often at the bottom corners where water sits.
- A bent frame or a panel that's out of square, so it won't seal even after adjustment.
- Rollers or parts that are no longer made for an older door.
- A door that leaks air or water no matter how it's adjusted.
When replacement is the right call, it can be a big upgrade. One Raleigh family swapped dated glass doors for a new sliding unit; see that door replacement project. Here's what happens on exterior door replacement day.

How to keep a sliding door rolling smoothly
Vacuum the track every month or two, especially in pollen season. Wipe it with a damp cloth. Don't oil the track: oil holds dirt and gums up the rollers. Keep the weep holes at the bottom of the frame clear so rainwater drains out instead of sitting in the sill.
What affects the cost of sliding door repair?
We bill by time and materials, so we don't publish a set price. What moves the total:
- Whether the door only needs adjusting or needs new rollers
- Whether parts are still made for your door
- Track repair, handle and lock hardware
- For a replacement, the door size and any rot in the sill or framing
Projects of $2,000 or more may qualify for 0% financing for 6 months, subject to approval.

Frequently asked questions
Can sliding glass door rollers be replaced?
Yes, on most doors. The panel is lifted out of the frame, the worn roller assemblies are swapped for matching ones, and the panel is set back in and adjusted so it rides level. If matching rollers are no longer made for an older door, we'll explain the options.
Why does my sliding door jump off the track?
Usually because the rollers are worn or set too low, the track is dented, or debris is lifting one corner of the panel. Cleaning the track and adjusting or replacing the rollers fixes most cases. A bent track or frame may need repair before the door will stay on.
Should I repair or replace a foggy sliding glass door?
Fog between the panes means the insulated glass seal has failed. The door still works, but it insulates less and the fog won't clear. Depending on the door, the glass panel or the whole unit can be replaced. We'll check the frame and rollers and explain which makes sense.
How long does a sliding door repair take?
Cleaning, adjusting and replacing rollers or a latch usually fits into a single visit of a few hours or less. Track repair, rot in the sill or a full door replacement takes longer. Your craftsman will confirm the expected time before starting.
