So I had to replace the garage door spring on one of the bays of the garage. Fortunately it’s a single door so just one torsion spring to deal with, and lucky for me both doors are wound the same way so I have one to replicate.
The first problem was finding a spring, I’m looking for a 0.207 in. Wire x 2 in. D x 25 in. L Torsion Spring in Yellow Left Wound for Sectional Garage Doors by Dura-lift. Evidently these are hard to find or very expensive. I went to home depot because they had it on their site but (sigh) it was an internet only order. So I thought screw HD, Amazon here I come. Bottom line it was $55 at Amazon (everywhere pretty much) and $35.93 at HD. They won. It was ship to the store, they didn’t let me know it arrived and couldn’t find it at first but I finally got it.
Installation was super simple, the one thing I wasn’t sure of is how many times to pre-wind the torsion spring to be able to properly list the door. It turns out it’s one full revolution for every foot of door. My door was 7 feet so it was 28 quarter turns of pre-wind. I’ve always been told to stay away from torsion springs, call a pro because they’re dangerous, I’m happy to say it’s completely doable if you take your time and look at what you’re doing.
