How to Fix a Garage Door That Opens Crooked

Watch where the lean starts

Before you diagnose anything, stand back and run the door through one full open cycle, watching the two top corners. Note exactly where the tilt shows up — right at the bottom as it lifts off the floor, partway up, or only near the very top of the travel. Where the lean starts narrows down the cause faster than anything else you can check.

A door that tilts from the first inch usually points to the spring side. A door that looks fine at the bottom but leans more the higher it goes usually points to a cable or track problem. Either way, a crooked door is telling you the two sides of the system are no longer sharing the load evenly — and that imbalance gets worse, not better, the longer you run it.

One spring doing more work than the other

Most double doors and many taller single doors run on two torsion springs, one over each side of the door, each one turning a cable drum that lifts its half of the door. If one spring weakens or snaps while the other is still near full strength, the strong side pulls its corner up faster than the weak side can manage — a visible, often dramatic crooked lift.

This is the single most common cause of a garage door that opens crooked on a two-spring system, and it rarely announces itself with a loud bang. A spring can lose tension gradually over months before it fully lets go. When Royal replaces one failed spring on a two-spring setup, we replace both — a fresh spring paired with a worn one just repeats the same uneven-lift problem again within a year. A double spring setup, both sides replaced and balanced, runs $320–$460 + tax; a single torsion spring on a one-spring system is $280 + tax.

A cable that's slipped off the drum

Each lifting cable spools onto a drum at the end of the torsion shaft. If a cable frays, stretches, or comes off its groove and rewinds unevenly, that side of the door travels less per rotation than the other — a lean that's subtle near the bottom and pronounced by the time the door is fully open. A cable that's partially unwound off the drum is also a snap risk, since the remaining wraps are carrying more load than they're rated for.

Frayed strands near the bottom bracket, a cable that looks loose or slack compared to its opposite side, or visible rust on the cable itself are all signs worth flagging before the door gets used again. Cable and bracket repair runs $180–$260 + tax, including a full inspection of both sides so the same issue doesn't surface on the other cable a few months later.

Track misalignment or a bent rail

If the tracks on either side of the door aren't perfectly parallel — one pulled slightly away from the wall, a bracket loosened, or a section bent from a bump — the rollers bind unevenly as they travel. This usually shows up as a lean that appears or worsens partway through the cycle rather than right at the bottom, and it can happen independently of the spring and cable system.

A quick visual check: look for daylight between a roller and its track on one side that isn't there on the other, a track bracket that's visibly pulled from the wall stud, or a rail with an obvious bow compared to its mirror image. Track repair and realignment is $180–$350 + tax. If the door has actually jumped the track rather than just running unevenly inside it, that's off-track repair, $180–$450 + tax.

Worn rollers add to the problem

Old, cracked plastic rollers or a bent roller stem create drag on one side without necessarily bending the track itself. On their own, worn rollers usually cause a rougher, noisier ride rather than a dramatic crooked lift — but paired with a slightly uneven track, they compound the lean and make it worse than either issue would cause alone. Roller replacement is $120–$220 + tax and is often bundled into a track repair visit since a technician is already inspecting both.

Why the spring and cable side is not a DIY fix

A torsion spring holds well over a hundred pounds of stored tension even on a standard residential door, and that tension doesn't go away because the door looks like it's just sitting there. Loosening, tightening, or trying to "wind up" a torsion spring without the correct winding bars and training is one of the most common causes of serious garage door injuries — fingers, hands, and worse, from a spring letting go under load.

Cables carry the same risk in the other direction: a cable under tension that slips while someone is adjusting a drum by hand can whip, and a door that's out of balance can fall unexpectedly if it loses its remaining support while someone is standing underneath it or reaching into the track. If the lean traces back to a spring or a cable, that's a call for a licensed technician, not a Saturday project — even for a company with 15 years of experience doing this daily, it's routine work handled with the right tools, not something to improvise.

What you can safely check yourself

A few things are fine to look at without touching the spring, cable, or drum system:

• Obstructions in the track — a stray screw, a chunk of debris, or built-up grime that could be catching a roller on one side only.
• Loose hardware — hinge bolts and track bracket bolts (not the spring anchor bracket) can be snugged with a wrench if they're visibly loose.
• Grinding or scraping sounds — note which side and at what point in the cycle it happens, and pass that along when you book — it speeds up the diagnosis.

If the door is leaning enough that it looks like it's binding hard against the track, stop running it. Continuing to cycle a crooked door risks jumping the track entirely, snapping a cable, or putting stress on the opener's drive gear from fighting an unbalanced load.

What a repair visit actually involves

A technician runs the door manually with the opener disconnected to see how it balances on its own, checks both springs' tension against each other, inspects the cable wrap on both drums, and runs a level along both tracks to spot any deviation. Most crooked-door calls resolve in a single visit once the actual cause is confirmed — the service call itself is free with any repair, and if it turns out the door doesn't need work after the assessment, the diagnostic fee is $120. A routine maintenance and tune-up ($120 + tax) also catches early spring wear and cable fraying before either one turns into a crooked-door call in the first place.

Royal Garage Doors recommendation

A door that opens crooked is a balance problem, and balance problems on a garage door involve components under real mechanical tension — not something to diagnose by trial and error. Stop using the door if the lean is pronounced, and don't attempt to adjust a spring or rewind a cable yourself. Book a repair visit and a technician will identify whether it's the spring, cable, track, or rollers and quote the fix on the spot — the service call is free with any repair.

Frequently Asked Questions

Why does my garage door look crooked when it opens?

The most common cause is one spring on a two-spring system losing tension while the other stays strong, so one side lifts faster than the other. A cable that's slipped off its winding drum or a track that's pulled out of alignment on one side can cause the same visible tilt.

Is it safe to keep using a garage door that opens crooked?

No. Running a door that's visibly unbalanced puts extra strain on the remaining spring and cable, and can lead to a cable snap or the door jumping the track entirely. If the lean is pronounced, stop using the door and book a repair rather than cycling it repeatedly.

Can I fix a crooked garage door myself?

Not if the cause is the spring or cable — torsion springs hold well over 100 lbs of tension and require winding bars and training to adjust safely. You can safely clear obvious track obstructions or snug loose hinge bolts, but spring, cable, and drum work should go to a licensed technician.

How much does it cost to fix a crooked garage door?

It depends on the cause: a single torsion spring is $280, a double spring setup is $320–$460, cables and brackets run $180–$260, track repair and realignment is $180–$350, off-track repair is $180–$450, and roller replacement is $120–$220, all plus tax. The service call is free with any repair.

What happens if I ignore a garage door that's opening crooked?

The remaining spring or cable carries more than its share of the load, which accelerates wear and increases the risk of a sudden cable snap, a spring failure, or the door jumping its track — any of which can damage the door, a parked vehicle, or the opener's drive gear.
