re: Garage door with Broken spring. Will it cost more that treefiddy? UPDATED

Spring broke when the door was down. Only one of the two broke I don't know what all is involved with changing one of those out. I know there is a lot of torque on those things.

That's probably best. One of mine snapped when it was in motion. A piece went flying across the garage.

Is there more than one type of spring for replacement?

You'll have to buy them by weight of your door. Mine is an older single wood door so it is fairly heavy. Newer aluminum door aren't as bad.

Get a long 2x4, raise the door up, and prop it up with that. Put another one on the other side as well. After that it is just removing the springs and replacing. Once the door is raised, most of the tension is off of the springs, and it is held up by the opener on the track. The springs just assist in lifting the door.

What you want to do is run a thin cable inside the spring and tie it off at both ends, and that way when it breaks again years down the line, the spring won't go flying across your garage. The hardest part is stretching it enough to get the pulley attached. That's where my strong neighbor came into play. He grabbed the spring with some vice grips and pushed it towards me and I bolted the pulley into place. Check out youtube.
