Common symptoms
- One side hangs lower
- Pleats stack tightly on one side
- The bottom rail twists
- The shade stops before reaching the sill
- A top-down bottom-up rail is not level
Safe checks before ordering parts
- Confirm brackets are level and fully engaged.
- Look for fabric pinched in an end cap or rail.
- Operate slowly and avoid pulling one side.
- Do not open a cordless rail unless the system is serviceable and you understand the spring tension.
Repair or replacement considerations
Some corded cellular shades can be restrung and re-leveled. Cordless or specialty systems may require a replacement mechanism, factory repair, or a new shade.
Safety note: Do not force controls, work above your ability, bypass cord-safety devices, or improvise brackets and electrical repairs. Follow product-specific instructions.
Common questions
Can I straighten an uneven shade by pulling the low side?
That can worsen the problem. Operate from the designated handle or control.
Why does a new shade hang slightly unevenly?
Installation, settling, fabric memory, or rail alignment may be involved.
Can damaged cellular fabric be repaired?
Small rail or cord issues may be repairable; crushed or torn cells usually are not.
