Quick answer
Yes — if your door has two springs and one broke, replace both. Both springs were installed together, carry the same load, and have cycled the same number of times, so the unbroken one is just as worn as the one that snapped. Replacing only one typically means a second breakdown and a second service call within months, plus an unevenly balanced door in the meantime.
- Two-spring door, one broken spring: replace both — this is the industry-standard answer for a reason.
- Both springs have identical age and cycle counts; the survivor is living on borrowed time.
- One service call with both springs costs meaningfully less than two calls months apart.
- Mismatched old and new springs balance the door unevenly, straining the opener and cables.
- Single-spring doors are simpler: replace the one, and consider upgrading to a two-spring setup on heavier doors.
A spring just broke
You heard the bang, the door is heavy or won't open, and the quote in front of you covers either one spring or two.
Comparing two quotes
One company quoted a single spring cheap and another quoted the pair, and you want to know if the pair is an upsell.
Planning a preemptive replacement
Your springs are past their rated cycles and you'd rather replace on your schedule than after a failure.
Compare your options
Replace both when the door has two springs
This is the right call in nearly every two-spring case. Springs are rated in cycles — commonly around 10,000, roughly 7 to 10 years of average use — and both springs on a door hit that limit together. The labor to do the second spring during the same visit is small, so the pair costs far less than two separate emergency calls. The honest tradeoff: yes, you're paying for a part that hasn't technically failed yet. You're buying out a failure that's already scheduled.
Replace just the one when
There are narrow honest exceptions: the other spring was already replaced recently (so the two aren't the same age), or money is genuinely tight this month and you accept in writing that the old spring is likely to follow soon. A reputable company will do the single spring if you choose it with eyes open. The tradeoff: an old and new spring wind differently, so the door balances slightly unevenly, and you're keeping the second breakdown — and second trip fee — on the calendar.
Step up to high-cycle springs when
Your household opens the door many times a day — multiple drivers, the garage as front door — standard 10,000-cycle springs can wear out in just a few years. High-cycle springs (25,000+) cost more per spring but stretch replacement intervals dramatically, which is cheap insurance on a high-traffic door. The tradeoff is purely upfront price; the math favors high-cycle the more you use the door.
On a single-spring door
Many lighter single-car doors run one torsion spring — there's no pair question, so replace the one that broke. Worth discussing while we're there: heavier doors on a single spring can be converted to a two-spring setup, which halves the load on each spring and means a future break leaves the door partially supported instead of dead weight. The tradeoff is the conversion cost, justified mostly on heavy or insulated doors.
Key terms and context
This guide is written for repair & maintenance decisions across the Four-State Area (WV, MD, VA, PA). It uses the same terminology you'll hear from technicians, estimators, and manufacturers.
Saving half now, paying double later
The single-spring repair saves the cost of one spring today and spends a full second service call — trip fee, labor, and another stuck-car morning — within months. It's the most predictable false economy in garage door repair.
Operating the door on one broken spring
Forcing the opener to haul an unbalanced door strains the motor, frays cables, and can bend the top panel. If a spring is broken, stop using the door until it's repaired — this is also dangerous to do by hand.
Accepting a quote with no spring specs
Springs come in specific wire sizes, lengths, and cycle ratings matched to your door's weight. 'Spring replacement' with no specs on the invoice is how undersized springs end up on heavy doors and fail early.
Proof, process & local validation
- Door Serv Pro has replaced springs across the Four-State Area — 4.9 stars across 1,700+ Google reviews, with $75 off spring replacement currently running.
- Every spring quote specifies size and cycle rating in writing, and high-cycle upgrades are always offered, never pushed.
- 24/7 emergency service from six offices means a broken spring on a Sunday night doesn't wait until Tuesday.
How we build this guidance
- Door Serv Pro technicians replace springs every day across six Four-State offices — we see exactly how soon 'the other spring' fails when it's left behind.
- We quote spring size and cycle rating in writing, so you know what you're getting — and we offer high-cycle springs when you want fewer future failures.
- Currently $75 off spring replacement, and 24/7 emergency service when the spring picks a bad morning.

Common questions
Do I need to replace both garage door springs if only one broke?
On a two-spring door, yes. Both springs were installed together and have absorbed the same cycles, so the intact one has the same wear as the one that failed and typically breaks within months. Replacing both in one visit costs less than two service calls and keeps the door balanced evenly.
Isn't replacing the unbroken spring just an upsell?
It's a fair question, because this industry has earned the suspicion. The difference is the reasoning: cycle wear is shared equally between paired springs, which is why replacing both is the standard recommendation across reputable companies and manufacturers — not a quota. If you'd rather do one, we'll do one and tell you honestly what to expect.
How long do garage door springs last?
Standard springs are rated around 10,000 cycles — roughly 7 to 10 years at average use, much less for high-traffic garages. Cold snaps are when worn springs let go, because steel contracts and the first lift of a frigid morning finds the fatigue crack. High-cycle springs at 25,000+ cycles stretch that timeline considerably.
What does spring replacement typically cost?
Industry-wide, replacing a pair of torsion springs typically lands in the low-to-mid hundreds installed, varying with spring size, cycle rating, and access. Beware quotes dramatically below that range — they tend to grow after teardown. We quote in writing before work starts, and $75 off spring replacement is currently available.
Can I replace garage door springs myself?
We genuinely advise against it. Torsion springs store enough energy to cause serious injury when winding or unwinding, and the work requires specific bars, spring specs, and technique. It's the one garage door job where the money saved doesn't survive contact with what can go wrong. Our DIY-vs-pro guide draws the full safe/unsafe line.
