How Do You Open A Garage Door With A Broken Spring?
This is a question on quora: How Do You Open A Garage Door With A Broken Spring? My take on it is naturally a bit different than the five answers there.
What are you dealing with?
I'm assuming it is a normal torsion spring system. Not a wood flipper door with P728 springs and hinges on the side or an old extension style spring system with pulleys and rollers up high on the sides. Have you got a one car garage or a two car garage? If it is a two car garage does it have one spring or two springs? Do you have an opener attached to the door? Is the door metal with no insulation and has places to grab the door? Does it have a metal back, weigh a ton, and has nothing to grab but the hinges? The answers vary based on what you have.
Two car garage with both, all of the, springs broken.
It is better not to lift the door unless you have three or more people. Reason being the cables are likely to get stuck. When the cables get stuck and you are by yourself, or have only one other person to help, then it is likely the door is going to go off track. The windows may break. The door sections may bend. The door may come totally off and hit your vehicle. If you have two people that can hold the door comfortably for minutes while a third or fourth person goes side-to-side minding the cables then it is possible to open the door safely. And do not use the opener to help lift the door in this scenario. (The opener can make things go from bad to extremely bad very quickly.) Instead call a garage door company and have it fixed so nothing gets damaged.
Two car garage with one spring still working
If one of the springs are still functional, and the cables are still properly wrapped around the drums, then you can open the door. Half the weight of the door, about 100 to 150 pounds, will need to be supplied by you. Or you can grab the door with one hand and then push the wireless transmitter with the other and help the door up. Yes it will be very heavy but a healthy strong person can do it this way. Remember you may be lifting close to 150 pounds and you may get winded but it can be done.
One car garage door with no insulation
You can open the door without the opener. Actually always avoid using the opener on a single car garage door. At most the door might weigh 100 pounds. You may have to hold the door and untangle the cables at the same time. I'm strong enough to easily do this. However many people aren't.
One car garage door with insulation
This is a bit sketchy. Use two people for this job. Don't use the opener. Very little that can go bad but with an insulated door it is a bit heavier and harder to hold on to.
Conclusion
If the cables are loose it's best not to attempt to lift the door and certainly don't use the garage door opener! If you have a light non insulated two car garage door and only one of the two springs are broken then it is possible to lift the door. You can in this case even use the opener to help. Best though to call a professional before you get your neighbors to help. Most of the serious door damage, broken windows, door falling down, is due to too many neighbors pushing at the same time. Broken torsion springs need a professional to replace them. And if you hire the right professional you'll get better springs and everything checked and serviced at a good price.
