A standard garage door torsion spring requires roughly 7 to 8 full turns (or about 28 to 32 quarter turns) of tension. The exact number of twists depends on the height of your door and the circumference of the cable drums, using the general formula of about 1 full turn per foot of door height plus an additional half turn.
As a general rule of thumb, a standard garage door torsion spring requires one full turn (or 4 quarter turns) for every 1 foot of door height, plus an additional 12one-half12 to 34three-fourths34 of a turn.
For standard two-car garage doors (16 feet wide), two torsion springs are strongly recommended. Single springs are often installed by builders to cut costs, but upgrading to a dual-spring system improves balance, safety, and longevity. Single springs are only sufficient for smaller, single-car doors (10 feet wide or less).
Long Life Torsion Springs
By using larger springs, you can, in most cases, quadruple your spring life while only doubling the cost of the springs. You will also avoid extra work down the road. The industry standard is 10-15,000 cycles for new doors.
Garage door torsion springs typically last for 7 to 10 years, or approximately 10,000 to 15,000 cycles (one cycle = one open/close). For a typical household using the door 3–4 times daily, this translates to about a decade, though heavy usage or extreme weather can reduce this lifespan.
Typically, using a single spring instead of two will save just two or three dollars. The installers also know that they can install a single spring with fewer cycles and get more money a few years down the road when the garage door is damaged.
A garage door can still open if the spring is broken, but it takes a bit of manual effort. Trying to open it automatically with the opener could strain the motor or burn it out since the broken spring makes the door heavier to lift. We recommend not trying to open your garage door if it has a broken spring.
No two garage doors are exactly alike, which is why spring repair pricing can differ from one home to another. Factors such as door weight, spring type, and installation complexity all play a role. Local labor rates, service availability, and the urgency of the repair also influence cost.
Repairing garage doors, particularly replacing torsion springs, is dangerous work, whether you are a do-it-yourself homeowner or an experienced technician. It is impossible to cover every dangerous situation you may encounter.
The two primary types of garage door springs are torsion springs and extension springs. Both counterbalance the weight of the door so it can be opened smoothly, but they use completely different mechanisms and placements.
Is it worth repairing a 20-year-old garage door opener? Generally, it's not. Garage door openers typically have a lifespan of 10 to 15 years. A new opener is often a better purchase because it comes with updated safety features and runs more quietly.
If you have two springs and only one of them is causing problems, we replace both regardless. This is because garage door springs work together. If one of the springs is stronger or newer than the other, it can cause further issues down the line. As a result, we always replace both springs as a course of best practice.
No, you should not use standard WD-40 on garage door springs. Standard WD-40 is a water displacer and degreaser, not a lubricant. It will wash away existing grease, cause the springs to dry out, and can even attract dust and dirt.
To check if your garage door springs are properly adjusted, disengage the opener and manually operate the door. A perfectly balanced door will take under 10 pounds of effort to lift and will remain stationary at any height. If the door slams shut or flies open, the springs require adjustment.
The most common reason is a broken spring. Without it, the opener can't lift the heavy weight of the door. Look for a torsion spring split in half, an extension spring stretched or broken, or test a TorqueMaster system by manually lifting the door. If it feels very heavy, the spring is broken.
Replacing two springs, common in double-car setups, usually costs $350 to $500. This price includes parts and labor, but can change based on the spring type and where you live. Torsion springs cost $30 to $100 each. Labor adds $75 to $150.
The average lifespan of a garage door spring is 7 to 10 years. However, instead of years, spring manufacturers measure lifespan in cycles (one full open and close movement of the door).
It usually ranges from £100-300 depending on your vehicle, and you can pay online.
Yes, you can manually open a garage door with a broken spring, but it is extremely dangerous and requires significant physical effort. A standard garage door weighs between 100 to 350+ pounds, and the springs are specifically designed to bear that weight.
Does home insurance cover garage door springs? Whether home insurance covers garage door springs depends on your policy and how the spring was damaged. If your policy covers your garage and the spring breaks due to a covered peril, it should cover garage spring repair.
Yes, forcing a garage door open with a broken spring is a bad idea. The springs counterbalance the door, so when one breaks the full weight shifts to the door and the opener, which can strip gears, bend rails, fray cables, misalign tracks, crack panels, and burn out the motor.
Garage doors are heavy, most weigh between 130 to 400 pounds. The spring system, either torsion or extension, is what makes it possible to lift the door with ease. When a spring breaks, that weight shifts entirely to the opener or your strength. Trying to open or close the door in this condition can be very dangerous.
