It you have a tilt-up door, you are looking at a $150 – $200 repair or replacement. If it’s a roll-up door it’s going to cost you more. Roll-up door spring repair or replacement is usually around $200 – $250 for a 2 car door. If the brackets need to be disassembled to remove the springs due to the shaft not sliding sideways enough it will cost you an additional $50 – $100.
On one-piece doors with side springs, you open the door to relieve the spring tension, and simply swap out the springs on the opener-arm mechanism; there are no cables or pulleys to deal with, and the springs have internal safety rods. Some doors have tensioners that maintain moderate tension when the door is open all the way, and on these you'll have to loosen the tensioner in order to remove the spring. https://www.youtube.com/embed/Z_eZc-kh40c
R-value describes the power of the insulation in your door. The higher the r-value, the stronger the insulation. Those doors will have better energy efficiency than doors that have a low r-value. Basic doors have an r-value of 0.0 with no insulation. The first step up gives you 1-3/8” insulation at a 6.5 rating. Next, a 1-3/8” thickness with Intellicore has a 12.9 r-value. The best option on the market is the 18.4 r-value, which has 2” Intellicore insulation.

Can you find what you need in the big home improvement stores? Can they show you how to fix a broken garage spring? Do they know what tools and replacement parts you need? Do they know what safety precautions you need to take? If you have any questions during the project, can you call them for help? Have they ever actually repaired a broken garage door spring themselves?

Doors come with one or two torsion springs. If either spring is broken, the garage door opener may struggle to lift the weight of the door or fail to open the door at all. If a spring is broken, call a professional for service as these can be very dangerous to work with. Don’t try to open the door until a professional comes to inspect it and replace the springs. Springs can only be used for a certain number of open and close cycles, and over time they will eventually break and need replacing.
When you're done watching this video you'll know how to determine whether the company you hired to replace your garage door spring installed the right size spring on your door. You'll also learn the consequences to your garage door opener if the wrong size spring is used. If you are having a problem with your garage door spring, the 2:30 minutes you spend watching this video is time will spent.

Springs are one of the primary components in all garage door systems. Torsion springs are usually mounted horizontally over the door opening. As the door closes, cables add tension to the springs and as the door opens that tension is released. The opening of the door causes the springs to unwind in conjunction with the weight coming off the door. This achieves a natural buoyancy. However, as the door moves up and down over time and the cycle count rises, the steel in the torsion springs will grow weak and will no longer be able to create energy or lift your garage door.


While it would be wonderful if door springs lasted forever, the reality is that the simple act of opening and shutting the door multiple times every day isn’t easy. It’s hard on the springs, even though they’re built to do it. Most springs will last for a while, but they won’t last forever. The regular wear and tear of endlessly opening and shutting the door breaks them down and eventually, they’ll need to be replaced.

If your door feels heavy, it is likely that your springs have started to wear down and are no longer capable of bearing the weight that they once did. Now, don’t worry, just because a spring is starting to lose its strength doesn’t mean it will snap at any moment. However, simultaneously, a weak spring isn’t any safer to try and repair on your own.

Even though most of us are likely used to seeing this small spring in place on our garage door, we don’t often think too much about it, and we simply count on it working when we need it to. Unfortunately, it doesn’t last forever and will eventually need to be replaced. It’s best to be proactive and notice when it begins to look worn down before it actually breaks. Otherwise, you may find yourself trying to open the garage door to drive to work one morning, only to find that the door won’t open because the spring is broken.
If you have a garage door opener and you suspect a spring has broken, do not disconnect the opener from the door (by pulling the red emergency release handle) while the door is open. If you do, the door can come crashing down under its nearly full weight, with nothing to stop it. This is an extremely dangerous situation. It is never safe to leave the door open when a spring has broken because someone might try to close the door without realizing how heavy it is. Or, they might pull the emergency release handle on the opener.
6.4 Test the fit of the bar in the cone before loosening a set screw. Insert one end of your winding bar into one of the holes of the winding cone. Pull down on the bar slightly to make sure the set screws are tight. Position your ruler between the bar and the garage door. Move the bottom of the bar from side to side and measure the play. It should be less than an inch and a half. If it is over 2" either get someone else to change your springs or have someone make some bars that will properly fit the cones.
