Heavy movement is usually mechanical
A sliding door should not require a shoulder push. Heavy movement often comes from worn rollers, dirty or damaged track, or panel alignment.
Cleaning is worth trying, but it has limits
If cleaning the track helps for a day and the door gets heavy again, the problem may be deeper than dirt.
- Vacuum visible debris
- Do not force the panel
- Listen for grinding
- Watch whether the lock still lines up
The right repair starts with diagnosis
PatioGlide asks about the symptoms first so the appointment is routed toward rollers, track, alignment, lock, or another door issue.
