Garage Door Spring Replacement Cost in Ontario (2026): What You'll Really Pay & Why

Want this fixed rather than explained? We do garage door spring repair and replacement in London, with the prices published up front.

Introduction

A broken garage door spring is one of the most common and most alarming repairs a homeowner will ever face. One day the door goes up and down without a thought; the next morning it will not budge, or it lifts a few inches and stops dead, or you heard a bang like a gunshot from the garage overnight and now there is a gap in one of the coils overhead. The spring is the single hardest-working part on the whole door, and when it lets go, the door is effectively out of service until it is fixed.

The first question almost everyone asks is the same: what is this going to cost me? The honest answer is that garage door spring replacement in Ontario in 2026 is not expensive by the standards of home repair, but the range of prices you will be quoted is wide, and the reasons for that spread are not always obvious. This guide lays out the real 2026 numbers for the London area, explains what actually drives the price up or down, walks through why professionals almost always replace springs in pairs, and gives you the questions to ask so you can tell a fair quote from a padded one. Every external link here points to a live page on a recognized industry body. Let us get into the numbers.

The Short Answer: 2026 Price Ranges

For a standard residential door in the London and southwestern Ontario market, here is what you should realistically expect to pay in 2026 for professional torsion spring replacement, parts and labour included, with a balance check afterward, and before HST:

• Single spring replaced on a single-car door (roughly 8 to 9 feet wide): $229 to $320 all-in.
• Pair of springs replaced on a single-car door: $260 to $400 all-in.
• Pair of springs replaced on a double-car door (14 to 18 feet wide): $300 to $550 all-in.
• Pair of high-cycle springs on a double door (upgraded for longer life): $420 to $620 all-in.
• Heavy or insulated double door needing an oversized spring set: $400 to $550 all-in.

Those numbers line up with what national and Canadian cost trackers report for 2026. Broad North American cost surveys put the typical professional single-spring job in the $150 to $350 range, with pairs and heavier doors climbing from there. Canadian shops tend to sit at the middle-to-upper part of that band once labour, travel, and a proper post-repair balance are included. If you have been quoted well under $200 for a complete professional job with a warranty, be a little suspicious; if you have been quoted over $700 for a routine pair on an ordinary door, get a second opinion.

Why the Price Varies So Much

A $200 quote and a $500 quote can both be honest, because they can be for genuinely different work on genuinely different doors. Here are the factors that move the number.

One spring or two

Most double doors, and many single doors, run two springs. Most single-car doors run one. Obviously two springs cost more in parts than one. The more important point, covered in detail below, is that when one spring of a pair breaks, the right practice is to replace both at once, not just the broken one. That single decision is the biggest swing in most quotes.

Standard springs versus high-cycle springs

A garage door spring is rated in cycles, where one cycle is one full open and one full close. A builder-grade spring is typically rated for about 10,000 cycles, which is roughly seven to ten years for an average family. A high-cycle spring rated for 20,000 or even 30,000 cycles costs more up front but can double or triple the lifespan. Our spring cycle life guide breaks down exactly how those ratings translate into years, and for a busy household the upgrade often pays for itself. Choosing high-cycle springs is the second-biggest driver of the price difference between two quotes.

Door size and weight

Springs are sized to the exact weight of the door. A light, non-insulated single-car steel door might weigh 90 pounds; a large, insulated, double-car door with heavy-gauge steel can push past 200 pounds. Heavier doors need larger, more expensive springs wound to a higher torque, so a big insulated double naturally costs more than a small builder single. Our garage door weight guide explains how much these doors actually weigh and why the spring has to be matched so precisely.

Torsion versus extension springs

There are two spring systems. Torsion springs mount on a shaft above the door and are the modern standard. Extension springs run along the horizontal tracks on either side and are common on older doors. The two systems price differently, and if your door still has extension springs, safety cables should be running through them (and if they are missing, that is a separate safety issue covered in our extension spring safety cable guide). Our torsion versus extension springs guide explains which system you have and the pros and cons of each.

Travel distance and service-call minimums

Every garage door company has a minimum service-call fee that covers the truck, the fuel, and the technician's time to get to you. In a compact service area like London that minimum is modest; for a rural property well outside the city, travel can add to the total. This is why the cheapest-looking part price online never reflects the real installed cost.

Why You Should Replace Springs in Pairs

This is the point that surprises the most homeowners, and it is worth understanding rather than just accepting. When your door has two springs and one breaks, your instinct is to replace only the broken one. After all, the other one still works. Here is why nearly every reputable technician will recommend replacing both.

Springs wear as a matched set. The two springs on your door were installed on the same day and have gone through the exact same number of cycles ever since. If one has reached the end of its fatigue life and snapped, the other is not far behind, usually within weeks or months. Replacing only the broken one means paying a second full service call in the near future when its twin fails.

There is also a balance issue. A brand new spring and an old, weakened spring pull with different forces. That mismatch throws the door out of balance, makes it hang unevenly, and puts extra side load on the rollers, the cables, the bearings, and the opener. Our garage door balance test guide shows the simple check that reveals whether a door is properly balanced, and a mismatched pair almost never passes it. The small saving from replacing one spring is usually erased by the faster wear it causes elsewhere.

For a single-spring door, this obviously does not apply; there is only one spring to replace. But on any two-spring door, the pair-replacement recommendation is not an upsell, it is sound practice, and a shop that quotes you both springs is looking out for the door rather than trying to inflate the bill.

What the Price Actually Includes

When you pay for a professional spring replacement, you are not just buying a length of coiled steel. A complete job includes:

• The correctly sized spring or springs matched to your door's exact weight, drum size, and track height.
• Safe removal of the old spring, which on a torsion system means controlled unwinding of any remaining tension with proper winding bars.
• Installation and precise winding to the correct quarter-turn count for your door's height. Too few turns leaves the door heavy; too many leaves it slamming open.
• A full balance check and safety test, including the auto-reverse check on the opener, so the door stops and reverses on contact as it should.
• Lubrication and a quick inspection of the cables, rollers, and bearings while the technician is there, which often catches a second small problem before it becomes a big one. Our garage door cable failure guide covers why the cables deserve a look during any spring job.
• A workmanship warranty, which a reputable shop stands behind. At AA Advantage Doors that is a four-year warranty on workmanship, and you pay only when you are satisfied.

That bundle is the difference between the low online part price and the real installed cost. The part might be $40; the value is in installing it safely and leaving the whole door running correctly.

DIY Spring Replacement: Please Do Not

It is technically possible to buy garage door springs online and replace them yourself, and some homeowners do. We strongly advise against it, and this is not a sales pitch. A wound torsion spring stores a tremendous amount of energy, and releasing or winding it requires the correct winding bars used in a precise sequence. A slipped bar or a wrong-sized tool at full tension can break bones, take out teeth, or cause far worse. The Door & Access Systems Manufacturers Association is unambiguous on this point: its garage door safety tips state plainly that springs, cables, brackets, and related hardware are under extreme tension and should be adjusted or replaced only by a trained door systems technician.

Beyond the injury risk, the savings are smaller than they look. By the time you have bought the correct springs, a matched pair of winding bars, and the winding cones, and factored in the risk of buying the wrong spring size (spring selection depends on wire size, inside diameter, and length, all matched to the door weight), the gap between a DIY attempt and a professional job with a warranty narrows considerably. A wrong-sized spring also leaves the door out of balance, which quietly wears out the opener and the rest of the hardware. This is one repair where the professional route is genuinely the better value, not just the safer one.

How to Get an Honest Quote

Spring replacement is, unfortunately, one of the repairs where a small number of operators overcharge, because the homeowner is stuck with a non-functioning door and feels pressure to say yes to the first number quoted. A few habits protect you.

Ask for the all-in price before work starts. A good shop will quote parts, labour, and the balance check as one clear number over the phone or on arrival, not a vague "we'll see when we get there."

Ask whether the quote is for one spring or a pair, and at what cycle rating. This one question explains most of the difference between two quotes. A $260 single-spring quote and a $460 high-cycle pair quote are not really competing; they are for different work.

Be wary of the door-to-door upsell. A technician who arrives to replace a spring and suddenly insists the entire door, opener, and every roller must be replaced today is a warning sign. Springs, cables, and bearings do wear together, and a genuine recommendation to replace a worn cable at the same time is reasonable, but a total-replacement hard sell on a door that was fine last week is not.

Check the company out first. A shop with a long local history and a clean record is far less likely to play games. You can verify a company through the International Door Association's find-a-professional directory, and our own Better Business Bureau profile shows our service history in London. Our guide to choosing a garage door company walks through the full checklist.

Spring Replacement Versus Full Door Replacement

A broken spring is not a reason to replace the whole door. Springs are a wear part; they are designed to be replaced two or three times over the life of a door. If your door is otherwise sound, replacing the springs and moving on is by far the smarter spend. Our how long does a garage door last guide explains which parts wear on which clock, and springs are near the front of that queue while the door panels themselves last decades.

That said, if your door is already 20-plus years old, has other failing hardware, is poorly insulated, or you have been thinking about a new look anyway, a broken spring can be a reasonable moment to weigh a full replacement. In that case, our cost of a new garage door in Ontario guide lays out current pricing for complete door replacement, and our price estimator lets you build and price a door online. For most homeowners with a door under 15 years old, though, fixing the spring is the clear answer.

Making Your Next Springs Last Longer

Once you have paid for new springs, a little care extends their life and delays the next bill. Three habits matter most:

1. Lubricate twice a year. A light coat of proper garage door spring lubricant, not a household oil, reduces friction and rust. Regular lubrication is one of the cheapest life-extending habits there is, and it protects the cables and bearings at the same time.
2. Keep the door balanced. Run the manual balance test in our balance test guide once or twice a year. A door that no longer holds itself halfway open is telling you the springs are weakening or the balance has drifted, and catching that early prevents a hard failure at the worst moment.
3. Book an annual tune-up. An annual professional visit catches worn cables, dry bearings, and drifting balance before they turn into a roadside-style breakdown. Our springtime tune-up guide explains what a good tune-up covers, and DASMA's homeowner maintenance guide is a solid printable checklist for the do-it-yourself portion.

If your door is on the busier end (a household that cycles it eight or ten times a day), spending the modest upcharge on high-cycle springs at the next replacement is usually the best single decision for total cost of ownership. You pay a little more once and replace them far less often.

Frequently Asked Questions

How much does it cost to replace a garage door spring in Ontario in 2026?

For a standard residential door in the London area, expect roughly $229 to $320 for a single spring and $300 to $550 for a pair on a double door, parts, labour, and a balance check included. High-cycle springs or heavy insulated doors run higher, into the $420 to $620 range for a premium pair. A complete professional job with a warranty that comes in well under $200 is worth a second look.

Why does one broken spring mean I should replace both?

On a two-spring door, both springs were installed together and have cycled the same number of times. When one fails, its twin is usually close behind, so replacing both avoids a second service call within months. Mixing a new spring with an old one also throws the door out of balance and wears out the cables, rollers, and opener faster. On a single-spring door this does not apply.

Can I just replace the broken spring myself to save money?

We strongly advise against it. A wound torsion spring stores enough energy to cause serious injury, and winding one safely requires the correct bars and technique. DASMA's safety guidance is clear that spring work should be left to trained technicians. Once you factor in the cost of the correct springs, winding bars, and the risk of buying the wrong size, the savings over a warrantied professional job are small.

How long should new garage door springs last?

A standard spring rated for about 10,000 cycles lasts roughly seven to ten years for an average family, while high-cycle springs rated for 20,000 to 30,000 cycles can last much longer. Actual lifespan depends on how many times a day you use the door. Our spring cycle life guide translates cycle ratings into real-world years.

What are the signs a garage door spring is about to break?

Watch for a door that suddenly feels very heavy, will not stay open halfway, opens crookedly, or makes a loud pop. On a torsion spring you may see a visible gap in the coils overhead. If the door is hard to lift by hand or the opener strains, get it checked before it fails completely, ideally while the door is still usable.

Will my home insurance cover a broken spring?

Generally no. Springs are a normal wear-and-tear part, and standard home insurance does not cover routine wear failures. Insurance may cover sudden accidental damage from an outside event, but a spring that simply reached the end of its cycle life is an out-of-pocket repair. Treat the annual tune-up as the inexpensive insurance instead.

Is it worth paying more for high-cycle springs?

For a busy household, usually yes. High-cycle springs cost more up front but can last two to three times as long, which lowers the total cost over the life of the door and means fewer surprise breakdowns. For a light-use door, standard springs are often fine. Ask your technician for both prices and decide based on how often you use the door.

Conclusion

A broken garage door spring feels like an emergency, and in the sense that it takes your door out of service, it is one. But it is also a routine, well-understood repair with a predictable price. For most London-area homeowners in 2026, a professional spring replacement lands somewhere between $229 and $550 depending on door size and how many springs, rising to $620 for a high-cycle pair on a double door. The biggest factors in where you fall are whether you are replacing one spring or a pair, and whether you choose standard or high-cycle springs. The rest is door size, spring type, and travel.

The two things worth remembering are these: replace springs in pairs on a two-spring door, and leave the actual work to a trained technician. Both save you money and grief in the long run.
