Garage door springs
Garage door springs are one of the most important components of your garage door, and are often overlooked until a major problem strikes. Springs that are appropriately sized and installed are crucial to having a well balanced overhead door. That, in turn, is essential to lengthening your garage door opener’s lifespan.
A garage door may have visible springs, in which case a break will be easy to spot, or hidden springs inside the shaft, in which case a technician can identify the break and replace the entire system with a more practical visible torsion spring system.
At Advantage Garage Doors, we only install oil-tempered garage door springs of the highest quality, in accordance with industry safety standards, to ensure proper function and promote longevity of your garage door system.
As garage door torsion springs are under extremely high tension, any damage to them represents a great deal of danger to you and your loved ones. Never attempt to repair or replace a damaged garage door spring by yourself, as this can result in very serious injury.
If you suspect one or both of your torsion springs are damaged or broken, call us immediately to neutralize this safety hazard in your home.
Are my garage door springs broken?
Several signs can point to damaged or broken garage door springs. Firstly, a deafening ”bang” is usually heard as the torsion spring snaps. Additionally, a spring that is improperly balanced, of the wrong size, simply damaged, or broken can make your door feel extremely heavy and impossible to lift manually – effectively trapping you in or out of your garage.
When in doubt, don’t hesitate to give us a call as damaged springs are extremely dangerous and should be replaced as promptly as possible by experienced professionals.
We perform same-day and emergency spring replacement and garage door balancing.
The garage door torsion spring mechanism
A garage door torsion spring system is made up of oil-tempered or galvanized steel coils. It is a counterbalance system composed of one, two, or more springs on a steel shaft running horizontally above your garage door, with a cable drum at each end. Three bearings support the system – one in the center and one on each end. The counterbalance cables run from two brackets at the bottom of your garage door to the cable drums. Most garage doors will have oil-tempered torsion springs, unless the home is located in a particularly humid or otherwise corrosive environment.
Winding up the garage door torsion springs creates the necessary torque to lift and lower your overhead door. The torque is transferred from the spring to the shaft, keeping the garage door cables taut. The cables wind around the cable drums, slightly unwinding the garage door torsion springs. After the door has opened and transferred to the horizontal tracks, the torque remaining in the springs is what allows the overhead door to remain in an open position.
The high tension in the torsion spring system is effectively what makes lifting and lowering your door possible. As such, any damage in this system is harshly felt!
How many garage door springs do I need?
The deciding factor in the number of torsion springs required for your door is its weight. Most single garage doors, made of aluminium or steel, only require one spring to provide the necessary torque to counter its weight. Larger residential doors will usually require a pair of springs. Extremely heavy doors, such as ornate wood garage doors, might require up to three or four springs.
Although only one spring is necessary in the case of very light doors, installing a pair of springs is recommended as it eases the pressure and wear put on the center bearing, lengthening your hardware’s life span.
Garage door spring lifespan
Your typical garage door torsion spring is built to last 10,000 to 15,000 cycles. A cycle is one opening and closing of your garage door. As springs are usually installed together, technicians tend to recommend replacing both when one reaches the end of its cycle life. The reasoning behind this is that the second spring should follow shortly, and having springs in different conditions accelerates the wear and tear of the newer spring. However, many factors come into play when considering the longevity of garage door springs, including but not limited to : door weight, environmental factors, poor maintenance, and damaged or loose garage door hardware.
