I entered true adulthood
Hope you had a garage door guy do it.
Mine let go and I had to re-tension it. Scariest thing I've done in many years.
If it ever goes again I'll be calling a garage door guy.
I did - I know these things are under tremendous tension, so I wasn't going to tackle that myself. $275 for new spring and installation (plus taxes), so not worth me taking the time to do it myself. He also lubricated everything and adjusted the door openers all included. Of all the things done around the house lately that we've paid for, this was by far the cheapest!
My dad's brother in law was killed by one of these things. Yes, leave it to the professionals.
