The U.S. Consumer Product Safety Commission says that about 30,000 injuries linked to garage doors are now reported every year in the United States. Many of these injuries have involved bruised or broken extremities. However, some have included serious shoulder, back, and head injuries leading to permanent disability or even death. What is the cause of these garage door injuries? One leading cause has been homeowners trying to repair or replace their own garage door springs.
Both types of springs are loaded, or under tension, when the door is closed. This gives them stored energy to help lift the door as it's being opened. When the door is all the way up, the springs are relaxed, or relatively so—they still may be under some tension. The mechanical difference between extension and torsion springs is that extension springs are loaded by stretching, or elongating, while torsion springs are loaded by twisting, creating torque.
As commercial and residential garage door service professionals, we’ve pretty much dealt with every issue you can think of when it comes to garage door repair. Even still, there are sometimes issues that continue to surprise us, like the tiny insect nest growing on the photo eye sensor or the tennis ball that somehow managed to knock the door entirely off its track. Even though these issues are uncommon, it’s nothing that garage door service professionals like us can’t handle!
Torsion springs do not last forever, regardless of what some companies claim. “Lifetime” springs do not exist – all springs have a lifespan. Most builders typically install the lowest costing door available and with that generally comes lower cycle springs. A torsion spring’s life is determined by the number of cycles the spring is rated to last. Whenever the door goes up and down is what is referred to as a “cycle.” The springs that builders install can last as little as 7,500 cycles which means the average homeowner could get 3-5 years of life.
Although garage door springs can break during any season and at any time, they most commonly break during the winter. This has to do with the temperature change. When the temperature sinks below a specific threshold, the metal will contract. This means it’s extremely possible for your door springs to shrink slightly during the winter months. This is hard on the springs and makes them more likely to break. https://youtu.be/Z_eZc-kh40c
