Replacing both springs is worth it on doors built with two, since the pair was installed together and wears out at nearly the same rate. With a single garage door spring replacement handling both sides, the door avoids a second breakdown and keeps lifting evenly from end to end.
Paying for one spring feels like the smaller expense upfront, yet the older spring left on the door often gives out soon after the first repair. This guide explains why paired replacement holds its long term value, from spring wear and door balance to warranty coverage and the cost of return visits.
Key Takeaways
- Springs installed together wear out at nearly the same pace.
- An older spring works harder once its partner breaks.
- Paired replacement avoids paying for a return trip later.
- Equal tension on both sides protects the door and opener.
- Both new springs start under the same warranty period.
Reasons Double Spring Replacement Is Worth It
Double garage door spring replacement pays off because two spring doors depend on both springs sharing the load, and one worn spring weakens the other.
| Consideration | Replacing One Spring | Replacing Both Springs |
| Upfront cost | Lower price on the day of service | $450 to $600 depending on spring size |
| Remaining spring life | Older spring stays in service near its limit | Both springs start fresh |
| Return visits | Likely second service call soon after | One visit covers the full job |
| Door balance | Old and new springs pull unevenly | Equal tension on both sides |
| Warranty coverage | New spring covered, old one left out | Both springs share one warranty start date |
| Long term value | Savings fade after the next failure | Fewer repairs over the life of the door |
Doors running on two fresh springs also give the owner a predictable timeline for the next round of service, upkeep, and household budgeting over the years ahead.
Both Springs Wear Out at the Same Rate
Springs installed on one day log an equal number of cycles, so once a spring breaks, its partner has usually reached a similar point of wear.
Shared wear shows up on the second spring in these ways:
- Coils stretched or spaced unevenly from years of use.
- Surface rust along the older, uncoated steel.
- Weaker lift that leaves the door heavy by hand.
- Grinding or squeaking during every door opening.
- Visible gaps forming between tightly wound coils.
Calls for a broken garage door spring repair should include a check of the second spring, since both near the end of their life together.
The Remaining Spring Carries Extra Strain
Once one spring fails, the remaining spring tries to lift the full weight of the door alone, which pushes it well past what it was sized to handle.
Added load on a single aging spring leads to problems like these:
- Extra strain that speeds up wear on the older coil.
- Uneven lift that tilts the door as it rises.
- Snapped cables that raise the risk of serious injury.
- Opener motors working harder to move a heavy door.
- Premature failure of the spring left in service.
Cables pulled out of line by an uneven lift often need a garage door cable repair at the same visit to restore even lift across the spring system.
One Visit Costs Less Than Two Service Calls
Two spring jobs run $450 to $600 based on spring size, and that single price covers the whole repair in one trip instead of two.
Booking both springs together saves money in these specific areas:
- One trip fee for the full job.
- Single round of labor costs for winding and balancing.
- Freedom from a second service call soon after.
- Lower risk of emergency service fees after hours.
- Replacement costs spread across springs with equal lifespans.

Balanced Tension Protects the Door and Opener
Equal spring tension on two new springs lifts the door evenly, which keeps stress off the garage door opener and the rest of the hardware.
Balanced lift from a fresh pair delivers benefits like these:
- Properly balanced door that glides without drifting or dropping.
- Less effort for the opener motor on each cycle.
- Straight travel with no tilt toward one side.
- Reduced wear on rollers, tracks, and hinges.
- Quieter, smoother operation throughout daily use of the door.

High Cycle Springs Stretch the Value of a Pair
Upgrading both springs to a higher cycle rating at the same visit extends the time between replacements, which adds even more value to a paired job.
Consider these points when choosing the cycle rating for both springs:
- Standard springs suit doors with lighter daily traffic.
- Frequent users gain more from high cycle springs.
- Higher upfront cost offset by fewer future replacements.
- Longer intervals between each spring repair visit.
- Better durability for heavy doors with frequent trips.

Paired Springs Share One Warranty Period
Installing both springs together starts one warranty clock for the pair, so coverage lasts the same length of time on each side of the door.
Common start dates for coverage make ownership simpler in these ways:
- Five year coverage on our Duramaster powder coated springs.
- One set of records for both new springs.
- Clear answers on which spring falls under warranty.
- American made steel backed by consistent quality standards.
- Simpler planning for the next professional spring replacement.
Homeowners comparing garage door springs from different companies should ask how long coverage lasts and whether it applies to both springs in a pair.
How to Decide Between Replacing One Spring or Two
Paired replacement makes sense for most two spring doors, yet a few details about the door and its setup still deserve a quick check before professional installation.
Work through these steps before approving the final quote:
- Confirm the spring type and whether the door runs on one spring or two.
- Ask how long ago the current springs were installed.
- Compare pricing for single and paired replacement side by side.
- Reserve single swaps for doors with one recently replaced spring.
- Plan the visit for weekday hours to avoid after hours fees.
Single spring doors and doors with one recently replaced spring are the main exceptions to replacing both springs at the same visit.
Replacing Both Springs Pays Off for Two Spring Doors
Two spring doors wear through both springs on the same schedule, so replacing the pair together protects the door, the opener, and the budget. Fresh springs on both sides deliver even lift, one shared warranty, and far fewer surprise breakdowns over the many years of daily use that follow.

Frequently Asked Questions
How soon does the second spring fail after the first one breaks?
Timing depends on daily use, yet the older spring has logged the same cycles as the broken spring and tends to fail soon after. Warning signs like slow lift or a heavier feel by hand usually show up on the older spring before it finally breaks.
Does replacing both springs cost twice as much as replacing one?
No, because the trip fee and much of the labor are shared, garage door spring repair costs for a pair run well under double. Our double spring price of $450 to $600 depends mostly on spring size and covers both springs in one professional service visit.
Can mismatched springs damage the garage door opener?
Mismatched springs pull unevenly, so the garage door opener has to work harder to lift the heavier side of the door. Keeping door balance even with two new springs reduces strain on the opener motor and its gears, helping both last longer.
Which doors actually need two springs?
Modern garage doors that use torsion springs often run two of them on heavier double door and insulated steel door setups. Door size and weight decide the type of spring a door uses, and our technicians confirm both on site before quoting.
Will both new springs fall under the same warranty?
Yes, both springs in a paired replacement start their five year warranty on the same date with our Duramaster springs. Shared coverage keeps records simple and supports customer satisfaction, since there is no question about which spring is protected.
Why do technicians recommend replacing springs in pairs?
Garage door companies with years of experience know the older spring is close to failure once its partner breaks, and replacing both prevents a return visit. Pairing also gives professional repair crews one clear baseline for tension, balance, and the regular maintenance schedule that follows.
Should extension springs also be replaced as a pair?
Yes, an extension spring on one side should be replaced along with its partner so both sides lift with equal force. Safety cables and pulleys usually get checked at the same visit, since they help contain the significant tension each spring holds.
How long will a new pair of springs last?
Lifespan depends on how often the door runs, and the right replacement springs sized for the door last far longer than undersized ones. Yearly checks for loose hardware and worn cables by a trained technician help extend the life of your garage door and its new springs.
When does replacing only one spring make sense?
Replacing one spring makes sense on doors built with a single spring or when the other spring was installed very recently. During a professional garage door spring repair visit, our team checks the other spring before recommending one spring or two.
