Why Uneven Opening Or Closing Is An Emergency
A garage door needs to rise up and lower smoothly and evenly. Anything else is a sign that something is wrong. Problems with garage doors aren't always emergencies, but in this case, they could very well be. Depending on the cause of a door that is uneven, you could need urgent repairs done as soon as possible.
A Cable or Spring Could Be About to Go
If a garage door is rising or lowering with one side higher than the other, something is not pulling one side of the door correctly.
