Many jobs around the house are fairly easy fixes. It’s relatively easy to clean out your fireplace, clean the leaves from the gutters or repaint a wall. It’s a different thing to replace your garage door spring. It’s careful work that is almost impossible to do correctly the first time. Garage door professionals spend a great deal of time learning how to do it properly, and even the most detailed instructions won’t make you an expert in the span of a few hours. It can be almost infuriatingly annoying at times and is simply better left to professionals.
Just like on a bike sprocket, your cables can sometimes become disengaged. Oftentimes, when a torsion spring breaks, the garage door cable will snap as a result. Sometimes, the cable will cause damage to a vehicle or wall, and if a person happens to be in the way of the cable it can cause serious harm. If you cables have snapped, you should call a professional to help you. See the video above.
Product was received in two days and was as advertised. Installing these myself saved around $150 but it took around 2-3 hours. I would imagine everyone's experience is going to be different. These springs appear to be heavier duty than the ones they replaced. I couldn't use the same slots for tension as the old ones and it was trial and error in adjusting the length of my pull cable until the door closed as it should. I need to replace the springs on my other garage door and would think that will take less than an hour based on what I learned from the first install. https://www.youtube.com/v/Z_eZc-kh40c&feature=youtube_gdata
Single panel doors can also be installed with (one piece track type hardware) that folds the door back with a single horizontal track on each side (which is mounted at the top of the wood frame) and a roller, (mounted to the top of the door on each side. A hinge on each side that attaches to the bottom of each side of garage door. Using track hardware, a car can be parked much closer to the door, as the whole door, when in the open position, rests completely inside of the garage door header. Track type hardware has much less arc when raising and lowering the garage door as opposed jamb type hardware.
If the door won’t move at all because of an alignment issue, then this problem isn’t one that you should try to tackle yourself. A garage door professional will have the necessary equipment needed to safely realign and repair your garage door. Additionally, if the track misalignment is beyond repair, a professional can install a new garage door track for you. http://youtube.com/e/Z_eZc-kh40c
