Your garage door springs are arguably the most important and MOST DANGEROUS part of your door. Springs wear out. When they break, INJURY can result. If you have an older garage door, have your springs inspected by a professional technician and replaced if needed. If your door has two springs, replace both, even if one is not broken. This will not only prevent any damage caused by the breaking of the second spring, but also keep your door working efficiently.
Spring Sizes and Types
Springs sizes are NOT all equal. Each door has a unique size, weight, and gauge of metal. This all changes the weight of the door and the size of the springs needed.
1. EXTENSION SPRINGS
Usually located above the upper horizontal tracks on both sides of the door, extension springs are the most common residential garage door spring type. In order to open the door, these springs extend — providing counterbalancing force to support the door. The more force that is applied (via hand or motor), the more the extension spring expands. All extension springs should be paired with safety cables. Safety cables prevent the extension spring from becoming a projectile in the event of a spring, cable or bottom bracket failure. These events can occur at any time while the door is open, closed or in motion. Safety cables should be installed on all extension spring doors.
2. TORSION SPRINGS
Whereas extension springs “extend” or “stretch,” torsion springs use torque to raise garage doors. Attached above the garage opening, torsion springs slowly twist and coil on the shaft whenever force is applied (via hand or motor).
Torsion springs come in a wider variety of options, including various wire sizes and lengths. These variations are calculated specifically dependent upon your garage door weight, height, track radius and more.
Springs can squeak and be noisy. This is caused by normal use and does not necessarily indicate a problem. Before calling a professional service technician, use a spray-on lubricant (recommended especially for garage doors). If the noise persists, call a professional garage door installer for service.
