Garage Door Crooked or Uneven — Why One Side Is Higher (Naples, FL)
One corner sits higher than the other, or the door leans in the opening. This is never cosmetic — something on one side has let go. Here is what, and what happens if you keep using it.

📞 Call & Mention ROLLER75See all coupons →A garage door is designed to be carried at both bottom corners simultaneously, by two cables under equal tension. When it sits crooked, that symmetry has been broken — which means a component on one side has failed, slipped or come loose. It is never a cosmetic problem and it does not correct itself.
Stop before you diagnose
- Do not run the opener. Each cycle drags the door further out of square, wears a groove in the track and can pull a roller out of the rail entirely.
- Unplug the opener so nobody else tries.
- Do not walk or park under it. A door being held unevenly can shift suddenly.
The five causes, most common first
1. A cable that snapped or unspooled
By far the most common. One lift cable lets go, or jumps off its drum, and that corner drops immediately. In coastal Naples the usual root cause is corrosion inside the strands and inside the wraps at the drum, where a visual check does not reach. See cable repair.
2. A drum that slipped on the shaft
Cable drums are held to the torsion shaft by set screws. If those loosen — or seize and then shear — one drum stops turning with the shaft and that side stops lifting in step. Aluminium drums with steel set screws are a galvanic pair, which is why this shows up more often near salt air.
3. A broken spring on a two-spring door
With one spring gone the remaining spring cannot balance the door evenly, and the door lifts unevenly and heavily. Look above the opening for a visible gap in a coil. See spring repair.
4. A failed bottom bracket or end hinge
The bottom brackets carry the full cable tension and sit at floor level where wet salt collects. A corroded bracket that tears out drops that corner instantly — and it is one of the most dangerous failures on a door, because the bracket is under direct tension.
5. Track that has drifted, or a jamb that has failed
Years of vibration back the fasteners out and the rail drifts away from the wall. On older Collier County homes the more serious version is a wood buck that has gone soft with moisture or termite damage, so the whole track is no longer held where it should be.

What a proper repair involves
- Secure and support the door before anything is touched.
- Release stored energy safely with proper winding bars where springs must be unwound.
- Identify which side failed and why — cable, drum, spring, bracket, hinge, track or jamb.
- Replace both cables if either was involved; they have the same age and the same corrosion history.
- Reset the drums so both cables are wound identically, then square the door in the opening.
- Check spring balance — with the opener disconnected the door must hold at waist height.
- Replace any roller or hinge that was damaged while the door was running out of square.
- Re-set opener force and limits and test both safety reversals.

What happens if you keep using it
A crooked door running under power is the single most reliable way to turn a $200 repair into a $1,200 one. In order: the rollers on the low side bind and wear the track; a roller leaves the rail and the door goes off track; the sections twist and hinges tear out of the panel; the opener strains and burns its drive gear. Every one of those is avoidable by unplugging the unit and making one phone call.
Preventing it
- Run a gloved hand along both cables twice a year — they corrode from the inside and give little warning.
- Rinse the door and the bottom brackets with fresh water quarterly if you are near the coast.
- Have the balance and the drum set screws checked at an annual tune-up.
- Keep the closing path clear — a door landing on an obstruction is how a cable unspools in the first place.

Crooked Garage Door — Frequently Asked Questions
Why is my garage door crooked on one side?
Because something on that side stopped carrying its share. Most often a lift cable snapped or jumped its drum. After that: a drum that slipped on the shaft, a broken spring on a two-spring door, a failed bottom bracket, or track that has drifted loose. It is never cosmetic.
Can I straighten a crooked garage door myself?
No, and this is one we would push back on firmly. The cables and bottom brackets are under full spring tension, and a door being held unevenly can move suddenly. Levering it square also usually bends the track further. It is a genuine injury risk for what is often a $150 to $350 repair.
Is it safe to use a garage door that sits crooked?
No. Every cycle drags it further out of square, binds the rollers, wears the track and can pull the door off the rail entirely. Unplug the opener and leave it. Continuing to use it is how a small repair becomes a panel and track job.
How much does it cost to fix a crooked garage door in Naples?
Most come out at $150 to $350 for a cable pair and re-squaring. If the drums have seized it is $250 to $480. A bottom bracket runs $120 to $280, and a spring pair $250 to $600. You get a firm price before work starts.
Why do both cables get replaced when only one broke?
Because both were fitted the same day, have run the same number of cycles and have corroded in the same air. The one that has not failed yet is at the same point in its life, and mismatched cable condition makes even winding on the drums impossible. Replacing one means a second call-out within months.
Could it be the track rather than the door?
Sometimes — track that has drifted as fasteners backed out will let a door sit off square. The more serious version in older Collier County homes is a wood buck that has gone soft with moisture or termite damage, so the track is no longer anchored where it should be. We check the jamb, not just the rail.
