Garage door torsion springs are powerful metal springs that are tightly wound to help in opening or closing your garage door. The tension created as the springs twists is held as mechanical energy. The metal springs are dense enabling them to continuously tighten and release for a long time without damage. Torsion springs are installed above the garage door and should be horizontal to the ground. A garage door can also have two torsion springs with one on every side of the door’s center assembly. The springs may be located on the right and left edges of the garage door or in the center.
How Garage Door Torsion Springs Work
When you lift your garage door, the torsion springs create tension that pulls the door up with the help of strong cable spools attached to a long shaft above the door. Most garage doors are heavy weighing up to 300 pounds but the torsion springs store enough energy to do all the heavy lifting for you. When you pull your garage door down either with an electric motor or by hand, the springs and the attached cables are wound tight. The tension created allows the garage door to open and close smoothly without slamming down. Opening a heavy garage door can be quite a workout hence torsion springs will make the work easier.
How Long Garage Door Torsion Last
The quality of torsion springs varies just like every other product. If they are made with inferior materials, they will eventually break. But even as strong as torsion springs are, they are also prone to wearing out since they wind and unwind all the time. The metal can weaken in humid climates as a result of rust but on average a good quality torsion spring can last for up to 10,000 cycles which is equivalent to 7-14 years (I.e when the door is opened and closed at least two to four times daily).
Replacing Your Garage Door Torsion Springs
It is important to inspect your garage door parts frequently since damaged springs will cause the garage door to slam to the ground hence you may not be able to open the door. It is advisable to call a professional to replace the torsion springs for you because removing damaged springs can be very dangerous. The coils have a lot of energy stored in them which may even be life-threatening to an inexperienced person. In order to replace broken torsion springs, the right tools are needed as well as a thorough understanding of spring mechanics.
Repair and Replacement Costs
Replacement of garage door torsion springs can cost between $20 to $30 for the springs. Inclusive of labor, it may cost up to $180 while the cost of repairing the door springs can cost between $100 to $200. Replacing a roll-up door will cost you more as it ranges between $200 to $250 (2 car door). Once your garage door springs are repaired, ensure that you use enough lubricant so that they do not get too tense. Too much tension will cause the spring to break.
