There are two different kinds of garage door springs. Torsion springs, and extension springs, also known as “stretch springs”.
Torsion springs are wound-up on a rod above the garage door opening, which in normal cases, there are a pair of them, one on each side of the center of the door. When one breaks the other spring will soon break, not far along after the first. So it’s safe to save money for another service call and have both replaced at once when the first breaks. Torsion springs are located on a long steel shaft that connects all of the cables, bearings, and mounting plates into one working system.
The other kind of springs are the kind that run along the upper, right and left door tracks and extend and stretch to do their job. These are known as extension springs, “stretch springs”. Stretch springs are not as difficult or risky to repair yourself at home; however safety measures are in order. When these springs are extended while the door is down, they are stretched to potentially send deadly force, possibly lifting a 400 pound door. Stretch springs, or extension springs, were commonly used before torsion springs were invented. There are a few retailers (Home Depot, etc.) that provide stretch springs with their garage doors, but this is considered laughable by industry standards. Even builders do not install these types of springs. The garage door often lifts unevenly on either side, and if the garage door has an attached garage door opener; you are going to have problems sooner rather than later. This is why most customers opt to go with a torsion conversion.
Lubrication is a Garage Door Springs’ Best Friend!
With now knowing that the springs over a garage door are clearly not a DIY project, we here at Plano Overhead Garage Door, suggest that you generously spray any new springs with a coat of 3-in-One Garage Door Lube to prevent the corrosion that is the starting point for springs failure. This is really the only thing a homeowner should do when it comes to either type of spring system.
Any type of spring can be deadly. Don’t mistake this as a do-it-yourself project, it is highly recommended to take careful safety precautions. We have had customers that had to have surgery, stitches, and wrist braces after failed attempts to do it themselves. It is safe to say, skydiving is safer; leave the replacement of springs to us! Here at Plano Overhead Garage door, we will have y’all covered indefinitely!
