The following instructions for replacing garage door springs are for do-it-yourself homeowners and for maintenance repair men who service their smaller commercial or industrial sectional overhead doors. These directions are designed for torsion springs mounted to both sides of an anchor bracket above the middle of the garage door as pictured above. Instructions for replacing a single torsion spring, for replacing garage door extension springs, and for replacing Wayne Dalton Torquemaster springs are linked to our DIY Instructions page above. You'll also find a link for any other garage door parts you may need while repairing your door.
How much should a garage door spring replacement cost? The national average is between $200 and $300 for a professional to come to your house and replace two springs. On line sources suggest a higher price of over $700 and that you will save $500 or more by replacing springs yourself. This is simply not true. To find the cost for replacing springs in your area look for a reputable company through Yelp or the Better Busienss Bureau. If clicking a site's BBB logo doesn't take you to the BBB site, we advise purchasing your springs from a different company. These instructions are for doors with cable drums and cables that look similar to those in the picture below. The next part beyond the end of the spring assembly is the cable drum. The drum is cast aluminum alloy 4" in diameter and 12.6" in circumference around the flat portion. Just beyond the cable drum is the end bearing plate. The cable unwraps off the back of the drum between the drum and the garage wall or jamb and travels down alongside the door, inside the track brackets and behind the roller stems as shown.
If your garage spring assembly is different from this, parts of these instructions may be helpful, but other parts may give dangerous, inaccurate directions which could cost you a lot of time and money should you attempt to replace the springs using standard instructions. For example, low headroom garage doors often have cable drums on the outside of the end plate and the torsion springs usually wind down rather than up. They normally have left wind springs mounted on the left side of the spring anchor bracket and right wind springs mounted on the right side of the bracket. The first part on the shaft beyond each torsion spring is the end bearing plate. Just beyond the end bearing plate is the cable drum. On these the cable often runs on the front of the cable drum. The bottom of the cable is attached to a bracket that wraps around the front of and outside the vertical track. Another example is the Ideal or Clopay EZ-Set Torsion Spring System for garage doors. These are distributed at Home Depot and Menards home centers.

In addition, one of our customers has provided excellent EZ-Set Torsion System instructions for removing the spring without wrecking the winding unit that secures the stationary cone.

Pictured above is an EZ Set system with oil tempered springs. Many of the newer doors have galvanized garage door springs.

For a scholarly introduction to torsion springs and for more information on how to install them I recommend you visit Richard Kinch's page, "How I Replaced Deadly Garage Door Torsion Springs and Lived to Tell the Tale." Richard is a brilliant engineer who has provided a wealth of technical information on fixing torsion springs along with valuable advice regarding some of the schemes unscrupulous garage door companies use to rip people off. If you have decided to replace your springs, if you are sure your door had the correct springs, and if you are ready to buy new ones, we recommend that you measure your spring or springs following the instructions in Step 4 below.
Measuring springs can be difficult; most individuals, even garage door technicians, sometimes have difficulty measuring torsion springs. Ordering incorrect springs wastes time and money. If you are not sure if your door had the correct springs, we recommend that you weigh your door using an analog scale. From my own field experience I would estimate that at least 10% of the doors have the incorrect springs on them. In addition to this, most manufacturers spring their doors using a 20 pound window. We like to improve the garage door balance. A third option is to determine the door size and model number. After you gather the necessary information you can order garage door springs. Before getting started on the replacement, it is essential that we begin these instructions with our sternest warning:Replacing garage door torsion springs is dangerous because the springs are under tension. If you do not use the right tools and follow safe procedures, you could lose hands, limbs or even your life.
You could also damage property. We want your business, but not at the expense of your well being. Doing the job right is your responsibility. If you have any doubts about your ability to safely change your springs, we recommend you hire a professional to repair your garage door. The following procedures are based on my 30 years in the garage door industry. In spite of my high mechanical aptitude, even after 18 years in the trade I lost the end of my left index finger. A few years later I had five stitches in my right thumb, and a year later five stitches in my left thumb. In 2004 emergency room staffs dug steel out of my eye and sewed up my ring finger with eight stitches. The best I can do is help you minimize the risk of injury; that's all I can do for myself. I am not so naive as to think that I have made my last trip to the emergency room. Repairing garage doors, particularly replacing torsion springs, is dangerous work, whether you are a do-it-yourself homeowner or an experienced technician.
