Garage Door Balance

[Jim356]

I am trying to balance my garage door after replacing one of the two regular torsion springs (that broke) on my heavy two car garage door. My main issue is that when I installed the new spring which matched the old one, it seems like I have each side wound properly but the door seems a bit heavy to open manually, stays open when half opened BUT slams open when it's close to being open. It seems like the springs have been "over-wound" to get open and half-way correct but it should not be crashing open between 3/4 and fully open. Would anyone have some advise as to how to adjust or should I have a garage door company come out?
(I installed the spring and am familiar on how to do it and the safety concerns)

Thank you, Jim

I would replace both springs at the same time. You have one new spring and one old stretched out spring.

ya, I've always heard that springs need replaced in pairs so they match in power.

Replace the other spring and try again!

Forum - Thank you all! I just ordered two new springs so they are matched from DDM Garage Doors online. They were very helpful and all I had to do is give them the serial number from my Clopay door and they knew what to send.

I will report back after installation. - Jim
