Small track damage can make a big door feel awful
A dent, worn rail, or rough surface can make the rollers grind and drag. That can turn into repeated roller failure.
Repair or replacement depends on the damage
Minor wear may be corrected. Severe track damage may need a stronger solution before the door can glide smoothly again.
- Dented track
- Sharp worn edge
- Rollers keep failing
- Door jumps
- Metal scraping sound
The final test is the glide
After track and roller work, the door should move smoothly and latch without forcing. That final test matters.
