A door can remain inside its tracks and still move poorly. Jack’s investigates uneven movement, rubbing and gaps so the proposed repair addresses the affected components. A roller that has actually left the track or a visibly hanging door needs an off-track assessment instead.
Describe where the movement changes
Does the door catch near the floor, lean while rising or rub at one side? Tell us the point at which you first noticed the problem and whether it followed an impact or other work. Do not run repeated cycles to make a video of an unstable door.
Check more than the track position
Alignment involves the relationship between the door sections, rollers, tracks, supports and lifting system. Moving a track without finding the source of uneven travel may leave the fault in place. A technician determines whether damaged hardware or a counterbalance issue also needs attention.
A floor gap needs its own assessment
An uneven floor and a door that hangs unevenly can both leave daylight below the bottom seal. Increasing opener force is not a sound way to distinguish them. We inspect the fit and movement before recommending alignment work, a compatible seal or further repairs.
Your questions, answered.
Is alignment the same as off-track repair?
Not always. Alignment can concern a door that remains in the tracks. A displaced roller, loose cable or hanging section changes the safety assessment and repair scope.
Can a new bottom seal fix every gap?
No. A seal cannot correct a distorted section, damaged lifting hardware or unsuitable floor geometry. Those causes need to be assessed before choosing weather sealing.
