Your garage door springs are the engine of the entire system. They store the energy that lifts a door weighing 150, 200, 300 pounds or more, and they release that energy in a controlled manner that allows a small electric motor to raise and lower the door smoothly thousands of times. Every component in the system — the cables, the drums, the rollers, the tracks, the opener — depends on the springs doing their job correctly. When the springs are right, everything works. When the springs fail, nothing works.
Spring replacement is not just another repair. It is the single most consequential maintenance event in your garage door's life. The springs you choose, the precision of the installation, and the compatibility between the new springs and the rest of the system determine how your door will perform for the next 7 to 15 years. The wrong spring — undersized, oversized, poor quality, improperly wound — creates problems that ripple through the entire system. The right spring — correctly specified, professionally installed, and matched to your door's weight, your usage pattern, and Locust's climate — delivers years of smooth, reliable, trouble-free operation.
Harrison is the team that Locust homeowners trust for garage door spring replacement because we treat this service with the precision it demands. We measure your door's actual weight. We calculate the correct spring specification — wire diameter, inside diameter, length, wind direction, and cycle rating. We install with controlled technique and professional tools. We balance the door, test the system, and verify safety function before we leave. And we use professional-grade springs from manufacturers we trust, not bargain inventory that will bring us back to your house in three years.
If your springs have broken, are nearing end-of-life, or need to be upgraded, call Harrison. We will put the right springs on your door and install them the way they should be installed.
A garage door spring system works on the principle of counterbalance. The springs store mechanical energy when the door is closed and release that energy to offset the door's weight when the door is opened. In a properly balanced system, the springs hold approximately 90 percent of the door's weight at every point in the door's travel, which means the opener motor only needs to provide the remaining 10 percent — a few pounds of force — to move the door. Without functional springs, the opener would need to lift the full weight of the door, which exceeds the capacity of every residential opener ever manufactured. Springs are not an accessory to the system. They are the system.
Garage door springs are made of high-tensile steel wire that is wound under enormous stress. Every time the door opens and closes, the spring flexes — winding and unwinding through its full range of deflection. This repeated flexing causes metal fatigue — microscopic changes in the steel's crystalline structure that accumulate over thousands of cycles until the metal reaches its breaking point and fractures. This is not a defect in the spring. It is the fundamental physics of cyclically loaded steel. Every spring has a finite cycle life, and when that life is consumed, the spring breaks.
When a spring breaks, the counterbalance force it provided vanishes instantly. The door becomes dead weight — 150 to 300 pounds or more with no mechanical advantage to lift it. If the door is closed when the spring breaks, the opener cannot raise it. If the door is open when the spring breaks, the remaining spring and cables may not be able to control the descent, and the door can crash down with dangerous force. A broken spring is not a gradual degradation. It is a sudden, complete loss of the force that makes the entire system functional.
Two springs can look identical and deliver radically different service lives based on the steel quality, the heat treatment, the wire consistency, and the manufacturing tolerances. Similarly, two installations can use the same spring and produce different outcomes based on the winding precision, the balance accuracy, and the attention to related components. Harrison controls both variables — we install quality springs, and we install them correctly — because both must be right for the replacement to deliver its full potential.
Torsion springs are mounted on a steel shaft above the garage door opening and work by twisting — storing energy as the coils are wound tight and releasing energy as they unwind. They are the standard spring type for modern residential and commercial garage doors.
When the door closes, the cables pull on the drums, rotating the torsion shaft and winding the spring tighter. This winding stores energy in the spring. When the door opens, the spring unwinds, rotating the shaft in the opposite direction, which spools the cables around the drums and lifts the door. The spring's torque provides the counterbalance force that offsets the door's weight throughout the entire range of travel.
Smaller, lighter doors may use a single torsion spring centered on the shaft. Larger, heavier doors typically use two springs — one on each side of the center plate — to distribute the load. Dual-spring systems provide better balance, smoother operation, and a critical safety advantage: if one spring breaks, the remaining spring holds approximately half the door's weight, preventing the door from crashing down with full force. Harrison recommends dual-spring systems for all doors heavy enough to warrant them.
Standard residential torsion springs are rated for approximately 10,000 cycles — roughly 7 to 10 years of typical use. High-cycle springs are manufactured with heavier wire gauge, larger dimensions, and higher-quality steel to achieve cycle ratings of 25,000 to 100,000 cycles — potentially 20 to 30 years of service. The price difference between standard and high-cycle springs is modest compared to the lifespan difference, making high-cycle springs an attractive option for homeowners who want to minimize future replacement events.
Oil-tempered springs are the industry standard — the steel is heat-treated and coated with oil for basic corrosion protection. Zinc-galvanized springs have a zinc coating that provides superior corrosion resistance, which is particularly valuable in Locust's humid and salt-air environment. The zinc coating adds cost but extends spring life in corrosive environments by protecting the steel wire from the humidity-driven oxidation that accelerates fatigue failure.
Extension springs are mounted along the horizontal tracks on either side of the door and work by stretching — storing energy as the spring extends and releasing energy as it contracts.
When the door closes, its weight pulls the springs, stretching them and storing energy. When the door opens, the springs contract, pulling the door upward through a cable and pulley system. Extension springs provide counterbalance force through a different mechanical principle than torsion springs but serve the same fundamental function.
Extension springs have several disadvantages compared to torsion springs. They exert force unevenly through the door's range of travel. They put lateral stress on the track system. They require more space along the horizontal tracks. And when they break, they can become dangerous projectiles if safety cables are not installed. For these reasons, the industry has largely moved to torsion springs for new installations, and many homeowners choose to convert from extension to torsion when their extension springs reach end-of-life.
Extension springs must always have safety cables installed — steel cables that run through the center of each spring and anchor to the track bracket and header. If an extension spring breaks, the safety cable contains the broken spring, preventing it from flying across the garage at lethal velocity. If your extension springs do not have safety cables, Harrison will install them as part of any extension spring service. This is not optional.
Wayne Dalton's TorqueMaster system encloses the torsion spring inside a steel tube, hiding it from view and containing it if it breaks. This proprietary design requires brand-specific tools and knowledge for replacement. The spring specifications, the winding procedure, and the tensioning method all differ from standard torsion systems. Harrison technicians are trained in TorqueMaster spring replacement and carry the necessary tools and knowledge to service these systems correctly.
Commercial and industrial garage doors use springs that are significantly heavier, longer, and higher-rated than residential springs. These springs may be wound on larger-diameter shafts, use heavier wire gauges, and be rated for 50,000 to 100,000 or more cycles to accommodate the high-frequency use patterns of commercial facilities. Harrison provides commercial spring replacement with appropriately rated products and commercial-grade installation.
Harrison — precision spring replacement for every system.
Call (888) 670-9331Every spring specification begins with the door's weight. Not the estimated weight. Not the weight listed in a catalog. The actual, measured weight of the specific door the spring will be lifting. Harrison measures door weight as part of every spring replacement because a spring rated for the wrong weight — even 10 to 15 pounds off — creates a balance error that affects opener performance, cycle life, and the entire system's operation.
These three dimensions define the spring's physical characteristics and performance. Wire diameter determines the spring's strength and cycle life — heavier wire is stronger and lasts longer. Inside diameter must match the torsion shaft size. Spring length affects the number of coils, which determines how the spring stores and releases energy. All three dimensions are calculated based on the door's weight and the system's mechanical requirements. Getting any one wrong results in a spring that does not perform correctly.
Cycle life is the manufacturer's rated number of full open-and-close cycles the spring is expected to complete before fatigue failure. A 10,000-cycle spring at four cycles per day lasts approximately 7 years. A 25,000-cycle spring at the same usage lasts approximately 17 years. A 50,000-cycle spring lasts approximately 34 years. The cycle life rating is the primary determinant of how long your investment will last, and it is directly influenced by the wire diameter, steel quality, and manufacturing precision of the spring.
Standard 10,000-cycle springs are the industry baseline and the least expensive option. High-cycle springs cost more but last proportionally longer. The decision comes down to simple math: how long do you want to go before the next replacement, and what is the total cost of ownership over that period? In most cases, the per-year cost of a high-cycle spring is actually lower than a standard spring because the higher purchase price is spread over a much longer service life.
Torsion springs are wound in a specific direction — left-wound or right-wound — and the direction must match the side of the door the spring is installed on. A left-wound spring on the right side (or vice versa) will unwind in the wrong direction, which means it will not lift the door and will create a dangerous condition when tensioned. This may seem like a basic detail, but it is a mistake that inexperienced installers make, and it is one that Harrison never makes.
In a dual-spring system, both springs must be the same specification — same wire diameter, same inside diameter, same length, same cycle rating, and same wind direction (one left, one right). Mismatched springs create uneven lifting force, causing the door to twist during travel, stressing rollers and tracks, and overloading the lighter spring. When Harrison replaces springs in a dual-spring system, we replace both with matched springs to ensure balanced operation.
Locust's humidity and salt air accelerate spring corrosion, which in turn accelerates fatigue failure. Harrison factors this environmental reality into our spring selection — recommending galvanized coatings for corrosion protection and, where appropriate, recommending high-cycle springs that provide a wider margin against the shortened service life that Locust's corrosive environment produces.
We begin by measuring the door's actual weight and assessing the complete system — current spring type and condition, cable condition, drum condition, bearing condition, track alignment, and opener function. This assessment informs the spring specification and identifies any additional components that should be addressed during the same visit.
Based on the door's measured weight, height, track configuration, and the homeowner's preferences regarding cycle life, we calculate the precise spring specification — wire diameter, inside diameter, length, and wind direction. We select springs from our truck inventory that match the calculated specification.
Removing a torsion spring requires controlled release of the enormous energy stored in the wound coils. Our technician uses professional winding bars and incremental unwinding technique to release spring tension safely and completely before removing the spring from the shaft. This is the most dangerous step in the process, and it is executed with the training, tools, and respect for the forces involved that safety demands.
With the springs removed, we inspect the torsion shaft for straightness, wear, and corrosion. We check the bearings at each end of the shaft for smooth rotation and secure mounting. We inspect the cable drums for worn grooves, proper positioning, and secure set-screw engagement. These components interact directly with the springs, and their condition affects spring performance and lifespan. Worn bearings, a bent shaft, or damaged drums are addressed before new springs are installed.
The new springs are installed on the shaft in the correct position and orientation. The winding process begins — each quarter-turn of the winding bar adds stored energy to the spring. The total number of turns is calculated based on the door's weight and the spring's specification. Too few turns and the door will be heavy, straining the opener and creating a safety hazard. Too many turns and the door will be light, rising too quickly and potentially causing the opener to force the door against the track stops. Harrison winds to the precise specification calculated for your door.
With the new springs installed and wound, we inspect the cables for fraying, corrosion, kinks, and proper routing. If the cables are in good condition, we re-tension them to match the new springs. If the cables show wear that warrants replacement, we recommend and can install new cables during the same visit — an economical pairing since the system is already disassembled.
The final and most important step. We disconnect the opener and test the door manually — a properly balanced door stays in place when lifted to the midpoint and released. If the door rises or falls, the spring tension is adjusted incrementally until perfect balance is achieved. We then reconnect the opener, adjust its force and limit settings for the newly balanced door, and test the complete system — cycling the door multiple times, verifying smooth and quiet operation, testing auto-reverse and sensor safety functions, and confirming proper balance throughout the full range of travel. The door must be perfect before we leave.
Measured. Specified. Installed. Balanced. Tested. Verified.
Call (888) 670-9331When one spring breaks on a dual-spring system, the other spring has endured identical conditions for identical cycles. It is the same age, the same steel, the same wear. It is statistically at or near the same fatigue point. Replacing only the broken spring and leaving the worn spring in place virtually guarantees a second failure in the near future — requiring a second service call, a second labor charge, and another period of door inoperability.
A new spring and an old spring will not produce identical force. The new spring will be stiffer and more consistent. The old spring will be weaker and more variable. This force differential creates uneven lifting, causing the door to twist slightly during travel. The twist stresses rollers, tracks, cables, and the opener. The system operates, but it operates under unnecessary strain that accelerates wear on every component.
The labor involved in spring replacement — tension release, shaft work, winding, balancing — is the same whether one spring or two is being replaced. The incremental cost of the second spring is just the spring itself, not a second service call. Replacing both springs during one visit typically costs 30 to 40 percent less than replacing them individually across two separate visits.
Single-spring replacement is reasonable when the system uses only one spring by design, when the remaining spring was recently replaced and is verifiably newer, or when the door is being replaced in the near future and maximum spring longevity is not a concern.
High-cycle springs achieve their extended lifespan through heavier wire gauge, larger physical dimensions, and in many cases, higher-quality steel with more precise heat treatment. The heavier wire flexes through a smaller percentage of its elastic range during each cycle, which reduces the fatigue accumulation rate and dramatically extends the number of cycles before failure.
Homeowners who use the garage door as their primary entry and exit — cycling it six to ten times per day — consume spring life at roughly twice the rate of homeowners who cycle the door three to four times daily. For high-cycle households, the upgrade from a 10,000-cycle spring to a 25,000-cycle spring can mean the difference between replacing springs every 4 to 5 years and replacing them every 10 to 12 years. The upgrade is most impactful for heavy users.
High-cycle springs typically cost 40 to 70 percent more than standard springs. But they last 2.5 to 3 times longer. When the total cost of ownership is calculated — purchase price plus service calls divided by years of service — high-cycle springs almost always deliver a lower annual cost than standard springs. The upfront premium buys a disproportionately longer service life.
Locust's humidity and salt air can shorten spring life by 20 to 40 percent compared to dry, non-corrosive environments. This means a 10,000-cycle spring in Locust may realistically deliver 6,000 to 8,000 cycles. A 25,000-cycle spring may deliver 15,000 to 20,000 cycles. The high-cycle spring still lasts dramatically longer, but the corrosion discount should be factored into the lifespan expectation. Galvanized coating helps mitigate this corrosion effect and is strongly recommended for Locust installations.
We recommend high-cycle springs for homeowners who use their garage door heavily, who plan to stay in the home long-term, and who want to minimize future service events. We recommend standard springs for homeowners with light usage, those who are selling the home in the near future, or those with firm budget constraints where the standard spring provides adequate service life for the ownership horizon. We present both options with honest cost and lifespan projections so you can make the decision that fits your situation.
Torsion springs provide smoother, more consistent counterbalance force through the door's full range of travel. They do not exert lateral stress on the tracks. They operate more quietly. They are contained on a shaft above the door rather than stretched along the tracks where they consume overhead clearance space. And when they break, they remain on the shaft rather than becoming potential projectiles. For all of these reasons, torsion has become the industry standard.
Converting from extension to torsion requires installing a torsion shaft, center bearing plate, end bearing plates, cable drums, and torsion springs above the door opening. The extension springs, pulleys, and associated hardware are removed. New cables are routed from the drums to the bottom brackets. The conversion is a more involved project than a simple spring replacement, but it results in a fundamentally better-performing system.
Extension-to-torsion conversion typically costs more than replacing extension springs with new extension springs — the additional hardware, the shaft installation, and the increased labor account for the difference. However, the long-term benefits — smoother operation, longer spring life, better safety, less track stress — make the conversion a sound investment for homeowners who plan to keep the home and the door for the foreseeable future.
Conversion makes sense when the door will be in service for many more years, when the homeowner wants the performance and safety benefits of torsion, and when the garage structure can accommodate the torsion hardware above the opening. Conversion may not make sense when the door is being replaced soon, when headroom above the opening is severely limited, or when budget constraints make the cost differential prohibitive.
Humidity is the most significant environmental factor affecting spring life in Locust. Moisture in the air promotes surface oxidation on the spring wire, creating microscopic pits that serve as stress concentration points. These pits become the initiation sites for fatigue cracks that propagate with each cycle until the spring fractures. The corrosion process is invisible during its early stages — the spring looks fine from the ground — but it is progressively weakening the wire with every humid day.
Coastal Locust properties experience salt-air corrosion that is significantly more aggressive than inland humidity alone. Salt accelerates the oxidation process and can reduce spring life by 30 to 50 percent compared to a protected inland location. Galvanized springs are strongly recommended for coastal properties, and more frequent spring inspection is advisable.
While Locust does not experience extreme cold, the daily temperature swings between air-conditioned garage interiors and hot outdoor conditions create thermal cycling that contributes to metal fatigue. The repeated expansion and contraction, while small, adds incremental stress that compounds with the mechanical cycling stress.
In a dry, temperate climate, the difference between an oil-tempered spring and a galvanized spring may be marginal in practical terms. In Locust, the difference is meaningful. The zinc coating on a galvanized spring provides a sacrificial barrier that absorbs corrosion before it reaches the structural steel. This protection extends the spring's useful life by slowing the corrosion-driven fatigue process that is Locust's primary spring killer. Harrison recommends galvanized springs for Locust installations as a standard practice.
Galvanized. High-cycle available. Matched to your door.
Call (888) 670-9331Spring replacement cost is determined by the spring type (torsion, extension, TorqueMaster), the spring specification (wire gauge, dimensions, cycle rating), whether one or both springs are being replaced, the condition of related components that may need attention, and whether the replacement is a straightforward swap or involves conversion or system modification.
For a standard residential garage door in Locust, single torsion spring replacement typically ranges from $200 to $350 including the spring, labor, and system testing. Dual torsion spring replacement ranges from $300 to $500. High-cycle spring replacement adds approximately $75 to $150 per spring over the standard price. Extension spring replacement ranges from $150 to $350 per pair including safety cables. Extension-to-torsion conversion ranges from $400 to $700 depending on hardware requirements. Commercial and industrial spring replacement is priced individually based on system specifications. Harrison provides exact pricing after on-site assessment, before work begins.
| Spring Replacement | Typical Range |
|---|---|
| Single Torsion Spring | $200 — $350 |
| Dual Torsion Springs | $300 — $500 |
| High-Cycle Upgrade (per spring add-on) | +$75 — $150 |
| Extension Pair (with safety cables) | $150 — $350 |
| Extension-to-Torsion Conversion | $400 — $700 |
A cheap spring — made from lower-grade steel with less precise manufacturing tolerances — will fail sooner than a quality spring. How much sooner depends on the quality gap, but the pattern is consistent: cheap springs deliver fewer cycles before failure, which means more frequent replacements, more service calls, and more total expenditure over the life of the door. Harrison installs springs from manufacturers whose products we have verified through years of field performance in Locust's demanding environment.
Spring replacement provides an ideal opportunity to address other components that are approaching end-of-life — cables, rollers, bearings, and hardware. Because the system is already disassembled for spring work, the labor to address these additional components is significantly reduced. Harrison presents bundled pricing when multiple components warrant attention, giving you the benefit of shared labor and a system that is comprehensively renewed in a single visit.
We calculate the spring specification based on your door's actual measured weight and system configuration. We do not install a generic spring and hope it works. We match the spring to the door because precision specification is the foundation of balanced operation and maximum service life.
We install springs from manufacturers whose products meet our quality standards — consistent steel, precise heat treatment, accurate dimensions, and reliable cycle life ratings. We know what we are putting on your door, and we stand behind it.
Spring replacement involves managing forces that can cause catastrophic injury. Our technicians are trained in the specific safety protocols, tools, and techniques required for safe spring handling. Every installation is executed with the discipline and respect for the forces involved that this work demands.
Every spring replacement includes inspection and service of the related components — cables, drums, bearings, shaft, and hardware. We do not install new springs into a system with worn cables and corroded bearings and call it done. We ensure the entire system supports the new springs' performance and longevity.
Our spring replacement is backed by a warranty covering both the springs and the installation work. If a spring we installed fails within the warranty period or if our workmanship does not meet standards, we return and make it right.
We present the options — standard or high-cycle, single or dual replacement, oil-tempered or galvanized — with honest cost and lifespan information so you can make the choice that fits your situation. We do not push the most expensive option. We present the facts and let you decide.

Single torsion: $200-$350. Dual torsion: $300-$500. High-cycle adds $75-$150 per spring. Extension pair: $150-$350. Extension-to-torsion conversion: $400-$700. Harrison provides exact pricing after on-site assessment.
Yes, on dual-spring systems. Both springs have identical age and wear. Replacing both costs 30-40% less than two separate visits and prevents a near-certain second failure.
Usually yes. They cost 40-70% more but last 2.5-3x longer. Per-year cost is actually lower. Especially valuable for heavy-use households and in Locust's corrosive climate.
Standard 10,000-cycle springs: ~7 years at 4 cycles/day. In Locust's humid climate, expect 20-40% shorter life. High-cycle springs (25,000-100,000 cycles) last proportionally longer.
If keeping the door long-term, yes. Torsion provides smoother operation, better safety, less track stress, and longer life. Conversion costs more upfront but delivers superior long-term performance.
Yes. TorqueMaster requires brand-specific tools and knowledge. Harrison technicians are trained in TorqueMaster replacement and carry the necessary equipment.
Higher-quality steel with precise heat treatment and consistent wire gauge delivers more cycles before fatigue failure. Cheap springs fail sooner, requiring more frequent replacements and higher total cost.
Yes, as standard practice. The zinc coating provides a sacrificial barrier against Locust's humidity and salt-air corrosion, meaningfully extending spring life compared to oil-tempered springs.
The springs on your garage door will determine how the door performs for the next decade. The right springs — correctly specified, professionally installed, properly balanced, and matched to Locust's climate — deliver years of smooth, reliable, trouble-free operation. The wrong springs — undersized, poorly installed, or cheaply made — deliver frustration, premature failure, and a second replacement bill that arrives far sooner than it should.
Harrison gets springs right. We measure your door. We calculate the specification. We install with precision. We balance until the door is perfect. And we back the work with a warranty that reflects our confidence in what we install and how we install it.
