Only if you don’t hate yourself.
That was mean, and a joke. But seriously, every time someone calls us for a spring replacement (note: singular), we always recommend that they replace both at the same time– It’s easier on them, easier on us, cheaper for them, and less of a headache in a few weeks for them.
Here’s what to consider: Springs that are installed at the same time wear down the same way in the same amount of time (provided your garage door system is in good repair). That means when one spring breaks, the other will likely follow soon, which is why it’s highly recommended you replace both at the same time.
But, if you want to pay more and see us more often, by all means, replace them one at a time!
