Weatherstripping works best when the panel is square
If the door is low, crooked, or hard to close, replacing the seal alone may not solve the draft.
Drafts can reveal movement problems
Light gaps, rattles, and uneven closing often connect to roller height or alignment. Those issues should be checked before parts are promised.
- Visible light gap
- Door rattles
- Seal is torn
- Panel does not close evenly
Photos are useful
A photo of the edge gap and lower track can help PatioGlide understand whether this is sealing, alignment, or roller work.
