Springs wear out from use, not age. Enter the rating, how often you open the door, and how old the spring is.
10,000 cyclesa common residential design numberDASMA rolling-door standards set a 10,000-cycle minimum for torsion springs, and residential sectional doors are often quoted the same. Springs rated for 15k, 25k or 50k cycles cost more. Ask for the rating in writing.
A garage door spring lasts a set number of cycles. One cycle is one full open and close (ANSI/DASMA 109).
A common spring is rated for 10,000 cycles, which is six to seven years at four opens a day.
After five years at that rate, about 7,300 cycles are used and 2,700 are left: under two years. Spring work is never DIY.

An estimate from cycle counts, not a warranty. Springs are never DIY. HyreGarage does not replace springs.
Why are garage door springs rated in cycles, not years?
Springs wear out by use, so makers rate them by how many times the door opens and closes. Once you know this, every spring quote gets easier to read.
ANSI/DASMA 109 defines one cycle as closed, then open, then closed again. A torsion spring is built to last a set number of those. When it reaches that number, it breaks. That is normal wear, not a defect, and usually nobody’s fault.
So there is no single answer to “how long do garage door springs last?” A couple who leave once a day and come back once use about 730 cycles a year. A busy family of four can use three or four times that.
Put the same spring in both houses. It might last thirteen years in the first and four in the second. Neither spring is faulty.
Why this matters when you get a quote. You can buy a spring rated for more cycles, but the rating is rarely written on the quote. Two bids a couple of hundred dollars apart can be a 10,000-cycle spring and a 25,000-cycle spring. The cheaper bid often means paying for another call-out sooner.
The one thing to remember: ask what cycle rating the springs have, and get the number written on the quote. “New springs” on its own does not tell you what you are buying. See spring cycle ratings compared for what each rating buys.
How many years will my spring last at my usage?
Find your spring’s rating in the left column, then read across to how many times a day your door opens. HyreGarage calculation: rated cycles divided by (opens per day × 365). We cap results at 25 years, because by then other parts decide how long the door lasts.
The lines drop fast on the left. Going from two opens a day to four cuts the life of every spring in half. How often you use the door matters as much as the rating you buy.

This is arithmetic, not a warranty. Real spring life also depends on how well it was installed, whether the door is balanced, and how it is handled. DASMA’s technical sheet on ANSI/DASMA 109 says plainly that rated cycles are not a promise.
Is a higher-cycle spring worth the money?
Usually yes. It costs more up front but less per year, and you pay for fewer call-outs.
Higher-rated springs cost more up front and less per year. These prices are examples only. Run your own quoted prices through the same sum.
Here is the sum. Divide the installed price by the years the spring will last at your usage, then compare.
On the example prices above, at four opens a day, a $300 10,000-cycle job costs about $44 a year. A $470 25,000-cycle job costs about $27 a year. The pricier spring is the cheaper one over time.
The call-out makes the gap bigger. Every spring replacement comes with a visit: a minimum charge, a trip fee, someone at your house for half a day. You pay that each time, whatever the spring’s rating.
Fewer replacements means fewer of those charges. The chart above only counts the springs, so it understates the saving.
When the cheaper spring makes sense. On a door you rarely use, like a second bay or a workshop opened twice a week, a 10,000-cycle spring can last decades. The same goes if you plan to replace the whole door within a few years. Save the money for the new door.
One catch. A higher rating is only worth paying for if it is real. It is real when it is written on the quote. Ask for it.
What makes a garage door spring wear out early?
An out-of-balance door, a single spring doing two springs’ work, rust, and an opener forcing a stuck door. The rating assumes a well-installed spring on a balanced door.
A door that is out of balance
If the springs were sized for a different door weight, every cycle strains them. This is the most common reason a spring breaks years early.
It often happens when a door is swapped and the springs are not recalculated. For example, a heavier insulated door hung on the old springs, or windows added to a solid section.
One spring where there should be two
A single spring on a wide, heavy door carries the whole load, so it works harder each cycle. With two springs, the load is shared. If one breaks, the other still holds some of the weight.
If you are quoted one spring for a double door, ask why. There can be good reasons, but it should be a choice, not a habit.
Rust
Springs sit in an unheated space open to the outside. Sea air, road salt off the car and a damp garage all attack the steel. A pitted spring breaks before its rating.
Galvanized or coated springs cost more. They are a sensible upgrade near the coast. In a dry inland garage they add less.
An opener forcing the door
If someone turned up the opener’s force to push past a sticking track or roller, every cycle adds strain. It also hides the real problem while it gets worse.
If someone adjusted the force to make your door work, ask what problem they were working around.
What should I do when a garage door spring breaks?
Stop using the door and call a specialist. A torsion spring breaks with a bang loud enough to sound like something hit the house. After that, the door will not lift. Do these things, in order:
Do not use the opener
Without a working spring, the door is dead weight. A double insulated door can weigh a couple of hundred pounds. Running the opener can strip its gears or drop the door.
Do not try to lift it by hand
For the same reason. If the door is partly open, leave it there. If someone already lifted and propped it, get everyone out from under it and leave it propped.
Do not pull the emergency release while the door is open
The release cord disconnects the door from the opener. With a broken spring and the door up, the opener may be the only thing holding it. Only pull the release with the door fully closed.
Only move the car if the door is already fully up and safe on its track
Otherwise, wait. A car is easier to replace than a person who reaches under a hanging door to get it.
Call a specialist and ask two questions when you book
What is the call-out charge, and does it come off the bill? What cycle rating are the springs you fit? The second answer decides when you will need to call again.
Replace both springs, not just the broken one
On a two-spring door, the other spring has done the same number of cycles. It is near the end of its life too. Replacing only one usually means a second visit soon.
Never open a winding cone
The winding cone is the part at the end of a torsion spring that holds its tension. It is the main hazard. There is no safe homemade tool, and this site will never explain how to do it.
Torsion or extension spring: which do I have?
Torsion springs
Where they are. On a metal bar (the shaft) fixed across the wall above the closed door.
How they work. They twist tighter as the door comes down, then unwind to help lift it. Cables run from drums at each end of the bar down to the bottom corners of the door.
Why most installers prefer them. Smoother, more controlled movement, usually longer life, and a broken torsion spring stays on its bar.
You need them for a wall-mounted jackshaft opener, which turns the torsion bar directly.
Extension springs
Where they are. Long springs along each side of the garage ceiling, above the horizontal tracks.
How they work. They stretch as the door closes and pull back to help lift it, using a pulley and cable on each side.
The safety issue. When one breaks, it can whip loose. That is why a containment cable (a safety cable) must run through the middle of each spring. If yours have none, book that repair now, whatever the spring’s age.
Switching to torsion is a real upgrade with a real cost. You need it if you want a wall-mounted opener.
Neither type is a homeowner job. Knowing which one you have helps you ask the right questions and price an opener upgrade. It does not change what you should do yourself, which is nothing. See garage door spring repair for what the job involves.

What should a garage door spring quote include?
Seven lines: the cycle rating, how many springs, the spring size, cables, bearings, the call-out fee and the warranty. Spring quotes are short, so a missing line is easy to overlook.
Line
What it should say
If it is missing
Cycle rating
A number per spring, like 10,000, 20,000 or 25,000.
You do not know what part you are buying. This is the most important gap, and the easiest to fix. Just ask.
One spring or two
How many springs are being fitted. On a two-spring door, that both are being replaced.
Ask directly. Replacing one of a matched pair often means paying for a second call-out.
Wire size, inside diameter and length
The three measurements that define a torsion spring.
Not a warning sign on its own. Many honest quotes leave it out. But a company that can give it to you took the measurements.
Cables
Whether the lift cables are being replaced at the same time.
Cables have done the same cycles as the spring, and they are already off during the job. Doing them later means paying for labor twice.
Bearings and drums
Whether the bearings at the ends and center of the bar are checked or replaced.
A worn bearing shortens a new spring’s life. It is cheap to fix while the bar is out and costly later.
Call-out or trip charge
The amount, and whether it comes off the bill if you go ahead.
Ask when you book, not when they arrive. This is the most common billing surprise.
Warranty terms
What is covered, for how long, and whether it covers parts only or parts and labor.
A cycle rating and a warranty are different promises. A one-year labor warranty on a 25,000-cycle spring is normal. A rating with no warranty is worth asking about.
How do I test if my garage door is balanced?
Lift the door halfway by hand and let go. If it stays put, the springs match the door. This takes ninety seconds and is the only spring check a homeowner should do. It does not tell you when a spring will break.
How. With the door fully closed, pull the emergency release cord to disconnect it from the opener. Lift the door by hand to about waist height and let go. Keep your hands and feet clear. Then lower it fully and reconnect the opener.
A pass. The door stays about where you left it, or drifts slowly. It takes the same moderate effort to lift all the way, not heavy at the bottom and light at the top.
If the door falls, the springs are too weak for it. They may have weakened with age, or the door was changed and the springs were not.
If the door rises, the springs are too strong. This often means someone added tension to push past a sticking track. If it is heavy in one spot, suspect the cables, drums or track instead of the springs.
What the test cannot tell you. It does not predict a break. A spring 100 cycles from the end of its life can balance the door perfectly until it snaps. Balance tells you the springs fit the door. The tool above is your only estimate of remaining life without paperwork.
If the door fails the test. Note what you saw, reconnect the opener and book a technician. Do not adjust anything. Never let anyone talk you through winding a torsion spring by phone. An unbalanced door also wears out the opener, so do not put it off.
What can this spring calculator not know?
It cannot see your real rating, your real usage, the spring’s history or how close it is to breaking.
Your actual rating. Unless it is on the installation paperwork, you are guessing. 10,000 is a common design number, not a safe guess about your door. Do not get close to a wound spring to read a label. Ask the company that fitted it.
Your actual usage. Most people guess too low. If it matters, count for a week. Every time you leave and every time you come back is a cycle. So is getting the bikes out.
The history. A spring fitted on an unbalanced door, or one that spent five years in a salty coastal garage, will not last as long as its rating suggests.
Whether it is about to break. There is no reliable warning a homeowner can see. Gaps between the coils, pitting, or a door that has become heavy to lift are worth reporting. But if you see none of these, that does not mean the spring is fine.
Prices. The prices in the cost-per-year chart are examples, chosen to show how the sum works. HyreGarage holds no data on real spring jobs and will not make any up. For how springs fail, see garage door spring failure.
Questions this calculator answers
How long do garage door springs last?
About 10,000 cycles for a common spring. One cycle is one open and close. Four opens a day is about 1,460 cycles a year, so that spring lasts six to seven years. In a quiet house it lasts much longer.
How many cycles is a garage door spring rated for?
Often 10,000. Springs rated for 15,000, 25,000 or 50,000 cycles exist and cost more. Ask for the rating in writing on the quote. See spring cycle ratings compared.
Can I replace a torsion spring myself?
No. Torsion and extension springs store enough energy to cause serious injury. The winding cones are the main hazard. Book a garage door spring repair instead. This site does not explain the procedure.
Should I replace both springs at the same time?
Yes, on a two-spring door. The spring that did not break has done the same number of cycles as the one that did. Replacing only one usually means a second service call soon.
What should I do when a garage door spring breaks?
Stop using the door. Do not run the opener or lift the door by hand. Do not pull the emergency release while the door is open. Then call a garage door company.
Is a higher-cycle spring worth the extra cost?
Usually, if you use the door a lot. It costs more up front but lasts longer, so you pay for fewer service calls. On a door you rarely open, a standard spring is fine.
