Garage door spring repair cost in 2023

Regular Price: $250 to $450
Average national cost: $350

In the current world, automatic garage doors have quickly become essential. Since homeowners depend so heavily on them, it’s easy to forget that they eventually deteriorate and require replacement parts—until they unexpectedly stop working. Since it does the heavy lifting each time you use the door, a broken garage door spring is the component that requires repair or replacement the most frequently. The typical cost of a garage door spring repair by a technician is $250, but the cost may be as high as $350.

The price of replacing a garage door spring will depend on the size of the door, the kind and quantity of springs, the number of doors, the location, and labor costs. Fortunately, a skilled professional can securely manage the issue of replacing broken garage door springs, so you can quickly resume using your garage.

Factors affecting the cost of replacing a garage door spring

A broken garage door spring will typically need to be completely replaced rather than mended. When you need to find out how much replacing a garage spring will cost, the estimate should include the price of labor and supplies for the type of doors you have.

Labor 

Using a trustworthy business with years of experience is crucial since garage doors are not easy to fix. Due to the weight and awkwardness of garage doors, the majority of businesses send two staffers to do repairs. According to HomeAdvisor, labor costs for the service visit typically range from $75 to $150. When you call for an estimate, a reliable business can tell you how long the repair of your door should take—typically 1 to 2 hours for spring replacement.

Materials 

In order to get the garage door operating again, replace the springs. This will cost you money for new springs, brackets, and hardware. A set of two springs, which is normal for a double garage door, typically costs $30 to $200. One door utilizes only one spring, so repairing it will be less expensive.

Regional cost of living

The final cost will depend on the demand and supply for garage door contractors. Costs for replacing a garage door spring will be greater in an area where there are fewer businesses. Since the cost of living is generally higher in metropolitan areas than in most suburban or rural ones, repair rates tend to be higher as well. On the other hand, if the technician must travel far to reach a rural home, you can be required to pay an additional trip cost.

The quantity of garage doors 

Both springs could break at the same time if your garage doors were all built around the same time and were utilized on a consistent basis. The double-door garages seen in the majority of homes use two springs to keep the door balanced as it raises and lowers. The elder spring receives uneven tension after one spring is changed, which will certainly cause it to break soon after. It is advised to change both springs at the same time for this reason. Ask about a discount to have all the springs replaced at once if you have a third or fourth garage door to avoid paying an additional service fee later.

Garage Door Style 

Torsion or extension springs are used in the construction of residential garage doors to generate the force necessary to raise and lower the garage at a controlled speed. Regardless of whether you have a tilt-up door or a roll-up door, the price depends on the type of spring that needs to be changed. Since a commercial garage door is larger, heavier, and used more frequently than the majority of residential doors, the springs are probably more prone to breaking. Commercial garage door springs range in price from $100 to $500, plus labor costs of $150 to $300.

Price of replacing a garage door spring

Cost of replacing a garage door spring: types of doors and springs
There are different types of garages, such as tilt-up and single-panel, despite the fact that the majority of garage doors are the sectional style, which rolls panels up along tracks. Despite the variations in style, each one of them uses a spring system to help balance the strain of physically raising and lowering the garage door. Torsion springs are an alternative to extension springs, which are the more conventional design.

Garage Door Torsion spring Cost

Since they continue to be under intense pressure while the garage is closed, replacing torsion springs is one of the riskier spring replacement procedures. They extend and twist firmly to open and close the garage door; they are fastened to the side wall of the building. Depending on use, torsion springs can last between 10,000 and 20,000 cycles (8 to 15 years) and handle greater weight than extension springs do. Torsion spring replacement costs, including labor and materials, range from $50 to $100 per spring or $75 to $150 for replacement torsion springs.

Extension garage door Spring cost

Extension springs only endure 8,000 to 15,000 cycles, or 7 to 12 years, while being less expensive than torsion springs. These hang just above the horizontal track of the door on a single long, narrow rod. The springs tighten and pressurize as the door is lowered, producing the spring action required to lift the door once more. Since they have more exposed elements than torsion springs do, they have safety cables attached to keep them in place when they break. Extension springs range in price from $15 to $45, while labor and material costs to replace them range from $50 to $100 per spring.

Garage Door Cable and Springs repair cost

In addition to springs, garage doors have cables that help lift and lower the door. They serve as a fallback system in case the springs malfunction. Keep an eye out for the following indicators that your cables need to be repaired: one side is heavier and lifting unevenly; the door whines when moving; or the door came off the track entirely. The cables could wear out before your spring. The wires can be changed by a professional for $75 to $200, but if they’re also replaced at the same time as a damaged spring, you’ll probably pay $175 to $450.

Two car garage door

The cost of the materials will be higher even though the labor rates for a double garage door repair are the same as for a single. The springs on double garage doors are larger than those on single doors. For instance, if an extension spring costs $15–45, then budget an additional $15–30 for each spring. The cost of replacing springs and cables combined will be higher because the cables are thicker to support the additional weight.

Garage Door Roll-Up

Since the price is primarily based on the type of spring being replaced, replacing springs on a roll-up garage door costs roughly the same as replacing springs on any other door. Roll-up doors typically require two torsion springs, so expect to pay between $150 and $300. Roll-up doors require the same amount of labor as any other form of garage door.

Cost of DIY garage door spring repair vs. Professional Service

Due to their ease of use, garage doors may appear to be straightforward to repair, but that is not the case. To lift a heavy door, garage door springs are constantly put under a lot of pressure. Because of this, fixing them might be a risky endeavor. You run the risk of dangerously hurting yourself or breaking any equipment or automobiles in the garage if you attempt to fix a garage door on your own. Additionally, you run the risk of making a costly mistake by fixing the wrong thing or doing it incorrectly. Replacement of the springs on a garage door should only be done by qualified personnel.

Asking for assistance from trained professionals who are competent to remove and repair broken springs is the most secure and safest way to replace a broken garage door spring. Additionally, since they are not your typical household springs, specific tools are needed. The next step is to ensure the door is properly balanced once the expert has removed and replaced the damaged springs. If you’re not experienced with this procedure, you risk damaging your garage door and having to replace it entirely. Another reason to hire a professional is that some warranties will not cover repairs or new parts if they are carried out by someone who is not a qualified expert.

Why Garage Door Spring Break or Fail

The main cause for getting a broken garage door spring is the use. These springs are designed to last an X number of life cycles. For most garage door springs standard life cycles are about 10,000. We see the majority of springs last about 10-12 years. 

There are springs you can get for your system with higher life cycle count. We are talking about double the life which means 20-25 years.

Weaken Spring Winding

Over time your garage door springs will lose strength. This will depend mainly on the quality of your springs. It is recommended to have a garage door expert to inspect your system and add winds to your springs if your door is unbalanced and feels too heavy when used manually. 

Rusted Springs 

Another factor to take into account when your garage door springs fail is to look for signs of rust. It is easy to tell if they are rusted. Normally, a spring is black in color. 

Rusted springs become brown and dusty looking. As the door gets worked, eventually the rust will help spring to break sooner than they were design to. 

Get a garage door spring expert to replace them when the spring shows rust and is ten years or older to prevent your car from getting stuck inside your garage.

Types of Garage Door Springs

There are two main types of garage door springs Extension and Torsion springs. These two have the task of counter balance the weight of your entire door. We will give a bit of information of what they are and how they work. 

Torsion Spring Overview

Torsion springs can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis. They offer resistance to twist or rotationally applied force. 

A spring of this type will reduce in body diameter and increase slightly in body length when deflected in the preferred direction of the fabricated wind. 

Depending on the application, torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind. Common torsion springs are those used in a clothes pin or a garage door.

Torsion Springs Characteristics

Garage Door torsion spring configuration is created for the purpose of storing and releasing angular energy or for the purpose of statically holding a mechanism in place by deflecting the legs about the body centerline axis. A spring of this type will reduce in body diamter and increase slightly in body length when deflected in the preferred direction of the fabricated wind.

The direction of the fabricated wind can also be important for torsion spring applications due to the leg bearing/attachment location having to be on the left or right side upon assembly.

A torsion spring is normally supported by a rod (mandrel) that is coincident with the theoretical hingeline of the final product.

Torsion Spring Measurements

1. Hold the spring in one hand, and the calipers in the other hand.
2. Place the caliper “teeth” on the inside diameter. This is called the Inside Diameter (I.D.).
3. Put the calipers on the “leg” to measure the wire. This is called Material Size (or Wire Diameter).
4. Place the calipers on the working coils of the spring. This is called the Body Length.Place the calipers on the working coils of the spring. This is called the Body Length.
5. Count the total coils, beginning at one end, just under where the leg leaves the body. Count to the other end, all full coils, and any fraction thereof. This is called Number of Coils and determines leg position. i.e. 90°, 180°, etc.
6. Determine the direction of coil (Wind Direction). See diagram for hand/finger illustration. Right Hand Wind or Left Hand Wind.

Torsion Spring Materials

The highest grades of spring wire are used when fabricating our torsion springs. To create cost-effective warehousing of our stock spring inventory for our customers, we offer material certification for custom springs only. Certifications of conformance for geometric tolerances set by the Spring Manufacturers Institute (SMI) are available for stock torsion springs upon request.

The term “spring steel” is a stock inventory term covering music wire, hard-drawn(MB) wire and oil-tempered wire. Additionally, stock torsion spring materials may include 300 series stainless steel.

Tolerances

Tolerance values for torsion springs depend on the body-diameter to wire-diameter ratio and are about +/- 10% in torque and +/- 5% in diameter.

Spring Finish

Our stock torsion springs come in a selection of commonly requested finishes:

• Zinc
• Gold Irridite
• Passivated (upon request)
• None (can be plated upon request)

Garage Door Extension Springs

Garage Door Extension springs are designed to absorb and store energy as well as create a resistance to a pulling force. It is initial tension that determines how tightly together an extension spring is coiled. This initial tension can be manipulated to achieve the load requirements of your particular application. 

All Century extension springs are wound with an initial tension force which offers a small deflection load for secure installation “holding”. The initial tension is equal to the minimum force required to separate adjacent coils. Each spring is of the constant diameter type with a variety of hook/loop styles. Spring Anchors are also available.

Garage Door Extension Spring Details

Extension Spring Measurements

1. Hold the spring in one hand, and the calipers in the other hand.
2. Place the calipers across the outside coil, either at the end or the center of the spring. This is called the Outside Diameter (O.D.).
3. Place the calipers on the wire at one end of the body coil of the spring. This is called the Wire or Material Size.
4. Place the calipers (or tape measure) on the full length of the spring, inside the hooks. This is called the Length (L.I.H.). (see diagram for example)

Spring Materials

The highest grades of spring wire are used in manufacturing Century Spring products. Certifications of conformance for geometric tolerances for our stock springs are available upon request. We only offer material certifications for custom springs.

“Spring steel” is a term that includes music wire, hard-drawn wire and oil-tempered wire. Alloy steels for stock extension springs are offered only in 300 series stainless.

Tolerances

Tolerances for extension spring rates depend upon the body-diameter to wire-diameter but are usually +/- 10% and +/- 5% on the diameter. The initial tension is much more difficult to control and is offered as a reference value only.

Garage Door Extension Spring Ends

The ends on the extension springs offered in our stock inventory are the common machine-made hook and full-loop configurations. The hooks or loops may have an across center transition of the last coil before forming the hook or loop. The angle between hook/loop planes (end position) is random. If you need a specific end configuration, it is best to contact our custom spring department.

Finishes

Our stock extension springs contain a selection of commonly requested finishes:

• Zinc
• Gold Irridite
• Black Oxide

Garage door springs counterbalance the weight of the door to make it easy to open and close. They serve the same purpose of counter weights used to balance doors in centuries past and in many doors today. For example, if a garage door weighs 100 pounds, a spring force of 100 pounds needs to pull against the weight of the door. This can be accomplished with springs that either stretch or torque special parts to assist in balancing the door. Replacing garage door springs is dangerous because of the torque in a wound torsion spring or the stretch in an extended extension spring.

What’s Involved in a Garage Door Repair

Garage door repairs often involve replacing garage door parts that are tied into the spring system, and many accidents, injuries and deaths have occurred for those who have not understood the forces at work. A proper understanding of garage door springs, garage door weights, garage door parts, and how these are interconnected is essential for safe repairs. Garage Door Torsion Springs Garage door torsion springs are secured to a metal shaft above the garage door. Depending on the system, the shaft may pass through the middle of the springs or spring, or the shaft may sometimes house the spring. If the shaft passes through the middle of the torsion spring, the spring may be mounted in the middle of the shaft or on the end of the shaft by the outside edge of the garage door. Torsion springs balance the garage door by applying torque to the shaft with drums at each end. Attached to each drum is a cable that extends to and is secured to the bottom fixture at the bottom of the door. The torsion spring unwinds and winds as the door is opened and closed to comprise a balanced system. Torsion springs have three characteristics that determine the lift and cycle life.

These properties are the wire size, inside diameter and length. The lift, which is determined by the torque of the spring, tells how much door weight the spring can lift. The cycle life tells how many times the garage door should open and close before the spring breaks.

Garage Door Spring Types

Standard Torsion Springs Standard torsion springs, pictured here, are secured to the spring anchor bracket and rotate a metal shaft with a 1″ outside diameter. Standard torsion springs are the most common residential torsion springs in the garage door industry.

Residential garage doors typically use either one or two springs. On a lighter garage door, one spring will suffice. In that case, the torsion spring may be mounted to the spring anchor bracket in the middle of the shaft above the garage door. Other times, the spring has an offset mount, meaning that installers do not mount the spring anchor bracket above the center of the garage door. If two torsion springs balance the garage door, they are typically mounted to the spring anchor bracket above the middle of the garage door. Having two springs on the garage door tends to make it safer, especially if one spring breaks when the door is open. The other spring will then keep the garage door from falling and injuring a person or causing damage to the garage door or other property. Does your door use standard torsion springs? Go to our Standard Residential Torsion Springs page to learn more and to order new springs for your garage.

Commercial Garage Door Springs

Commercial garage door springs Standard Commercial Torsion Springs Commercial and Industrial garage doors typically have at least two torsion springs. Many of these doors use four or more torsion springs in one of four setups: linear, duplex, triplex, or mixed. Linear System: Two springs installed on the left side of this garage door, with two other springs on the right side as well.

Common Linear Spring System

Linear System: Two springs installed on the left side of this garage door, with two other springs on the right side as well. The linear system comes into good use more commonly with wider garage doors through which large vehicles need to enter. Since these garage doors tend to be wider, four or more torsion springs line up on the shaft with ease. Customers installing the linear system gain the advantage of less costs for the springs and spring hardware than for the materials in the duplex / triplex spring systems.

Duplex Spring System

Duplex System: On the left of this picture is the shaft with a bearing and the spring anchor bracket. The end of the wire on both torsion springs hooks into the stationary cones. Duplex System: On the left of this picture is the shaft with a bearing and the spring anchor bracket. The end of the wire on both torsion springs hooks into the stationary cones. The duplex system only appears to have two very large springs, one on each half of the garage door. Inside of each torsion spring, however, is another spring with a smaller inside diameter. The duplex spring system supplies extra torque, and thus lift, from the torsion springs without needing the extra space on the shaft as with a wider garage door system.

Triplex Spring System

The triplex system functions very similarly to the duplex system. In this setup, there are two springs inside the outer spring.

The mixed system, as you guessed, features a combination of the linear system and the duplex / triplex system. Mixed systems use more than one set of duplex or triplex springs on each half of the garage door. This becomes an option for installers when the garage door shaft measures long enough to accommodate multiple springs. If one of these garage doors weighs very heavy, it is sometimes a better option to have multiple pairs of duplex springs sets on the garage door. Users of the duplex and triplex systems, however, often find it difficult to detect a possible broken inner spring. Since commercial industrial doors tend to weigh more, the torsion springs used in these settings usually have a larger inside diameter and wire size than residential torsion springs. While the springs on many doors use shafts with a 1 “outside diameter, some doors instead use a 1-1 / 4” outside diameter shaft.

How are they different

These shafts are only used with bearings, cable drums and winding cones with 1-1 / 4 “openings for the shaft. Heavier doors often use a soild shaft while lighter doors tend to use hollow shafts. Some solid shafts are keyed, giving a groove along the length of the shaft that, when coupled with a shaft key, can help keep the cable drums from spinning loose.

Garage Door Extension Springs

Extension Springs Garage Door Extension Springs Garage door extension springs are usually mounted along the sides of the garage door or above the horizontal tracks. Extension springs stretch and contract as the door operates to counterbalance the weight of the door. Most residential garage doors only have two extension springs – one on each side of the door. Commercial doors, however, as well as some residential doors, often have multiple springs installed on each side. Extension springs have either open loops, closed loops, or clipped ends to secure the spring to the garage track hang, pulley, pivot pin, frame or tension adjusting bolt.

Sectional Garage Door Extension Springs Sectional garage door extension springs are the more common type of extension springs installed here in the United States. These springs stretch above and parallel to the horizontal tracks on each side. They counterbalance the garage door by pulling on the cables. As the door closes the door weight is transferred from the tracks to the cables, and the door it gets heavier, but the springs are also stretching and pulling against the cables to balance the door and make it easier to operate.

Residential Garage Door Extension Springs

Residential garages almost always use two springs, one on each side of the door. One end of each spring usually connects to an open-eye bolt. This bolt usually fastens to the angle iron that holds to track or to a beam in the garage frame. The end of the extension spring is attached to a pulley The other end of the extension spring connects to a pulley with a pulley fork. One end of the cable that goes over this pulley is attached to a cable adjustment clip. An S-hook attaches to this clip, as well as to the horizontal track. The other end of this cable rolls over a second pulley and down to the bottom fixture on the bottom section of the garage door. Cable on extension spring attaches to clip. S-hook attaches to the track While one end of the cable attaches to the bottom fixture, the other end attaches to a cable clip. An S-hook secures this clip to the track.

Commercial Garage Door Extension Springs

Commercial and industrial overhead doors have an extension setup very similar to residential garage doors. On heavier doors, there may be a special kit that connects the ends of multiple extension springs. This allows two or more springs to be stretched simultaneously on each side of the garage door. Not all commercial and industrial garage doors have this setup installed. Some still just use one extension spring on each side.

For the most part, though, the rest of the system functions the same as with residential doors. Pulleys supply lift in both types, though commercial pulleys tend to be a lot stronger and capable of lifting heavier doors without premature breakage.

EZ-Torsion Springs

Clopay EZ-Set Torsion Spring System: The white plastic shaft retainer holds the shaft next to the cable drum, which sits next to the winder. EZ-Set torsion springs appear very similar to standard torsion springs, but the hardware is quite different. Door installers mount EZ-set springs to winders on the ends of the shaft, which is also 1 “in diameter. The black winder has the letter” R “or” L “on it, corresponding to the right or left side of the garage door. As with standard residential torsion springs, typically one or two springs fit on the shaft. While most two-car garages will have two EZ-Set torsion springs and single-car garages only one spring, this does not always hold true. Some lighter 2-car garage doors only have one EZ-Set torsion spring. In this case, the spring is usually mounted on the left side of the garage door.

Some of the wider garage doors have two shafts with a coupler in the middle to connect the two. This extra piece of hardware can save you a lot of time and trouble replacing your EZ-Set torsion springs in cases with very little space between the end of the shaft and the wall. Double-car garage doors, with either one spring or two springs, will have a center support bracket (pictured). Single car garage doors will not have this bracket–typically nothing supports the middle of the shaft. Does your door use EZ-Set torsion springs?
