Decko Door or Floor Misalignment

Decko opener operates normally but door does not fully seal at the floor on one side.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Uneven garage floor, Twisted door sections, Worn or compressed bottom seal, Incorrect track or spring adjustment

Safety first: Disconnect the opener and work with the door in the down position.

Check floor and seal:

Inspect the floor for low spots. Consider installing a threshold seal if the floor is uneven.
Replace the bottom seal if it is hardened, cracked, or permanently compressed.

Check door alignment:

Ensure both vertical tracks are plumb and at equal distance from the door edges.
If the door is twisted or panels are damaged, have a door professional adjust or repair it.
