A garage door that lifts on one side, hangs at an angle, or closes crooked is telling you its balance has been lost, and balance is the one thing a garage door depends on to work safely. A crooked door is not a cosmetic issue to shrug off. It usually points to a cable, spring or roller problem, and continuing to use it can pull the door off its track entirely. This guide explains what is likely happening and why it is worth acting on quickly.
Quick answer
A garage door that opens unevenly or hangs crooked has lost its balance, usually because a cable has snapped, a spring has weakened or broken, or a roller has failed on one side. It is not safe to keep using, because an unbalanced door can jam, twist, or come off its track. Stop running the door, keep clear of it, and book a repair. This is a same-day job for a technician.
Why balance matters
A garage door is designed to lift evenly on both sides at once, held in balance by matched springs and cables. When that balance is even, the door glides. When one side loses its support, the door tilts, the rollers on the low side get forced against the track, and the whole thing starts to bind. Every trip up and down in that state grinds parts and risks the door jumping its track. That is why a crooked door is a stop-and-fix problem rather than a live-with-it one.

| Door catches or tilts at one point | Failed roller or bent track | Off-track / roller guides |
| Door closes crooked, gap at bottom | Balance or track issue | Book a diagnosis |
What’s likely happening
A snapped cable
This is the most common cause of a suddenly crooked door. The cables keep each side lifting in step. When one snaps, that side stops being supported and the door lifts unevenly or drops on the failed side. If you can see a loose steel cable, this is your answer. The snapped cable guide covers what to do, and the short version is: stop using the door.
A weak or broken spring
Springs lose tension as they age, and on a door with two springs, one weakening faster than the other pulls the door out of balance. A fully broken spring makes the door heavy and unbalanced at once. The broken spring guide explains the warning signs.
A failed roller or bent track
If one roller has broken or a section of track has been knocked out of line, the door binds and tilts at that point rather than across the whole width. This can be the start of an off-track door, so that guide is worth reading if the door catches at a specific spot.
Why you should stop using it now
An unbalanced door gets worse fast
Every time you open a crooked door, you risk it jamming, twisting a panel, or coming off its track, which turns a straightforward cable or spring repair into a much larger job. An unbalanced door can also drop unexpectedly on the unsupported side. Keep people and vehicles clear, and do not try to force it level by hand. The parts involved are under tension and are not safe to handle without training.
What repair involves
The technician checks the whole balance system, cables, springs, rollers and track, rather than just the part that caught your eye, because a crooked door usually has one clear cause and a couple of parts that have taken strain because of it. Cables and springs are replaced in pairs so both sides pull evenly again, any failed roller or bent track section is dealt with, and the door is cycled and balance-tested before we finish. A properly balanced door should open smoothly and stay put wherever you stop it.
What it costs in Edmonton
The price depends entirely on which part caused the imbalance. Typical ranges are shown on the relevant guides: cables and springs on their own pages, off-track and roller work on theirs. As a guide, spring pairs run $280 to $450 and cable pairs $180 to $320, both plus GST.
Frequently asked questions
It only leans a little. Can it wait?
It is better not to wait. A small lean means the balance is already off, and each use risks turning it into a bigger problem or an off-track door. Booking it early keeps the repair small.
Can I just adjust one side to level it?
No. The cables and springs that control balance are under high tension and are not safe to adjust without training. Trying to level the door yourself is how people get hurt. Leave it to a technician.
Will a crooked door damage my opener?
It can. An unbalanced door forces the opener to work harder and pull unevenly, which wears the motor over time. Fixing the balance protects the opener as well as the door.
