Garage door problems
Garage door won’t close all the way
A garage door that won’t close all the way, stopping short or leaving a gap, usually has a close limit set too short, a sensor that trips near the floor, or a seal or floor that keeps it from sealing.

The short answer
A garage door that won’t close all the way, stopping short or leaving a gap, usually has a close limit set too short, a sensor that trips near the floor, or a seal or floor that keeps it from sealing.
If it stops and reverses, read the problem as a reversal fault. If it stops and stays a few inches up, the close limit is the first thing to adjust.
Key takeaways
close limit.
sensors or force. See the reversal page.
the seal or the floor.
a cable or spring issue. Stop.
What can I check?
Sensors mounted too high can see the door’s bottom edge as it closes.
Torn, folded or frozen seals stop a tight close.
A dip or a raised spot changes where the door meets it.
Adjust per the manual, a little at a time, then retest auto-reverse.
What a technician checks
Uneven cables leave one side high.
A track out of line changes where the door stops.
Correct retainer and seal size.
Gap or reversal?
| What you see | Fix direction |
|---|---|
| Even gap along the bottom | Adjust the close limit. |
| Gap on one side | Floor slope or a cable issue. Have it looked at. |
| Door reverses near the floor | See keeps going back up. |
| Light under a closed door | Replace the bottom seal or threshold. |
What to ask before you sign
On a sloped or worn floor.
The full ten-point checklist is on choosing a garage door company.
Where this goes wrong
The door then presses into the floor and may reverse or strain.
If one side hangs low, the cause is a cable or spring. Stop.
A worn seal lets in water and pests even when the limit is right.

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.

- states our own company records cover — and the limit of any claim made from them

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.
Sources & retrieval dates
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.
