Sliding Door Grinding or Noisy Hear it grind every time?
Grinding means something is dragging that should be rolling. Usually it’s a worn roller scraping the track, and every slide makes the track a little worse. Listen closely: the sound tells you a lot.

Likely causes
What the noise is telling you
Most common first. The numbers match the drawing.
-
Cause 1: Worn or seized rollers Most common
What you hear: A metal-on-metal grind along the whole slide.
When a wheel wears through or cracks, the metal housing around it rides on the track. When a bearing rusts solid, the wheel stops turning and skids. Either way, metal is scraping aluminum.
-
Cause 2: Sand and grit in the track
What you hear: A gritty crunch, often worse at one end.
Sand crunches under the rollers and scratches the track. It’s the easiest noise to fix, so rule it out first.
-
Cause 3: A dent in the track
What you hear: A thump or click at the same spot every time.
The rollers drop into the dent and bump out of it on every slide. The rest of the track can be fine.
-
Cause 4: Panel riding too low
What you hear: A scrape, usually louder at one end.
If the rollers have worn down or the adjustment has slipped, the bottom of the panel drags on the track or the sill.
-
Cause 5: Top of the panel rubbing
What you hear: A squeak or rub from up high.
The top of the panel runs in a channel in the head of the frame. If the panel sits too high or the channel is bent, it rubs there instead of gliding.
Before you book
Narrow it down
These help you tell a dirty track from a worn part. None of them involve taking anything apart.
Don’t lift the panel off the track
Sliding glass panels are heavy, and impact panels are heavier still. Getting one out means taking its full weight and tipping it out of the frame. If it slips, it can land on someone or crack the glass. Leave that part to us.
-
Vacuum the track and wipe it clean. If the noise was sand, it’ll be gone.
-
Slide the door slowly and listen. Noise at the same spot every time points to the track. Noise the whole way across points to the rollers.
-
Look at the bottom of the panel from the side. If it’s almost touching the track, the rollers are worn.
-
Use the door as little as you can until it’s fixed. Every pass on a worn roller files a little more off the track.
When to book
Still grinding on a clean track?
Then metal is touching metal, and now is the time to get it fixed. Today it’s probably a roller job. Keep sliding it and the track wears down too, and then the fix is new rollers plus a track repair or a stainless track cap.
The price comes after we’ve seen it. Every door is different, so we don’t guess over the phone. A specialist looks at your door and gives you an exact price, free, before any work starts.

The fix
How we fix it
Rollers first. If the track is already chewed up, it needs work too, or the new rollers wear out early on the rough surface.
-
Roller replacement
Worn or rusted rollers replaced so the panel rolls with one hand again. -
Stainless track caps
A stainless steel cap over a worn aluminum track gives the rollers a new running surface. -
Track repair
Dented or worn bottom tracks repaired so the rollers have a straight, clean path. -
Tune-ups & maintenance
Preventive maintenance: we clean, lubricate and adjust your sliders so they keep rolling smoothly.
We don’t replace glass or install new doors. We fix the one you have.
Several doors? Ask about multi-door savings.
Is it OK to keep using a door that grinds?
You can, but each slide costs you. A roller worn down to its housing scrapes the aluminum track like a file. Fix it early and it’s usually rollers alone.
Can new rollers fix a worn track?
Not on their own. New rollers on a gouged track still ride rough and wear out sooner. We repair the track or fit a stainless steel track cap over it, which gives the new rollers a smooth surface to run on.
What kind of rollers do you put in?
Whatever fits your door and its weight, single or tandem. Wheels come in nylon or steel, and housings in plated or stainless steel. Near the coast, stainless holds up better in salt air.
My door squeaks rather than grinds. Is that the same problem?
It’s often a close relative. A squeak usually means a dry or failing roller bearing, or the top of the panel rubbing in the head track. If it still squeaks on a clean track, it’s worth having us take a look.
If I send you a video of the noise, can you tell me the price?
Send it. A video helps us bring the right parts, but it isn’t a quote. Every door is different, so we don’t guess over the phone. A specialist looks at your door and gives you an exact price, free, before any work starts.
