Garage door problems
Garage door bent bottom section
A garage door with a bent bottom section needs more care than a dent higher up, because the bottom section carries the brackets that hold the lift cables under spring tension.

The short answer
A garage door with a bent bottom section needs more care than a dent higher up, because the bottom section carries the brackets that hold the lift cables under spring tension. Do not unbolt or straighten it yourself.
If the door still runs evenly, close it and have it checked. If it is crooked, binding or a cable looks slack, stop using it and call a technician.
If this is happening now
Stop and leave the door alone if you see a broken spring (a gap in the coil above the door), a loose or snapped cable, a door off its track or hanging crooked, or a door that has fallen.
Do not run the opener and do not pull the release cord on an open door: the springs and cables hold enough stored energy to cause serious injury, and CPSC says a door that is out of balance should be serviced by a professional.
Keep people and cars clear and call a garage door technician. You can also reach HyreGarage on (866) 582-8523.

A car bump or ice often bends the bottom.
What the technician does
Before removing the bottom brackets.
Or the retainer.
And the opener limits.

It is under cable tension from the springs. This causes serious injuries.
It can weaken the section and shift the brackets.
It can jump the track or fall.

Primary-source research, data analysis and fact checking
We are not a garage door company. We read the agency file, the code record, the standards document or the public register ourselves, compute the figure from it, and publish it with the source and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. Our own company records cover ten states; nothing national is ever derived from them.
- 10
- states our own company records cover — and the limit of any claim made from them
- 3,901
- garage door companies in the store
- 457
- license records verified against a state board

How this desk works
- Primary sources only. Injury counts come from CPSC. Housing counts come from the Census file, not from a summary of it. Code history comes from the building commission that adopted the code. We do not cite an article that cites a source; we retrieve the source and do the arithmetic ourselves.
- Every figure carries its retrieval date. Registers change, datasets are revised and codes are amended. A number without the date it was read cannot be checked, so every study states one.
- Fact, calculation and analysis are labeled apart. A quote is a quote, a HyreGarage computation says so, and an interpretation says “HyreGarage analysis”. Presenting our reading of a dataset as something the agency stated would be the easiest way to lose the only thing this desk is for.
- Limitations go above the fold. If a figure is an upper bound, a bracket, or an association rather than a cause, that is said before the figure is quoted rather than in a footnote underneath it.
- No DIY instructions for spring, cable or track work. Those components hold enough stored energy to cause serious injury, and CPSC records the consequences. We describe what has failed and what a competent repair involves; we do not tell you how to do it.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.

Information on this page is general and varies with the door, the opener, local code and circumstance. It is not safety, insurance or legal advice.
Springs and cables hold dangerous stored energy: adjusting or replacing them is work for a trained technician. HyreGarage does not repair, replace or install garage doors.
