Garage door springs come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift the weight. Extension springs run along the sides and stretch to assist. Most residential doors in Scotland use torsion springs because they're safer, quieter, and last longer (typically 7 to 9 years with regular use). A snapped spring means your door won't open or close smoothly, and you'll need professional help fast.
Walk into your garage and look up. If you see a thick horizontal rod with coils wound around it above the center of your door, that's a torsion spring. These are the gold standard for most homes. They balance the weight of your door (which can be 300 to 500 pounds) using stored rotational energy. One torsion spring failure and your door becomes nearly impossible to open manually.
Extension springs hang on pulleys along both sides of your garage opening. They stretch and contract like a slinky. While less expensive upfront, extension springs wear out faster and pose a safety risk if they snap under tension. That's why we always recommend torsion springs for Scotland homeowners who plan to stay in their homes long term.
The spring type determines repair cost, lifespan, and whether you should replace one or both. If one torsion spring fails, the other is likely close behind. We typically replace both at the same time to avoid a second service call in six months.
Spring failure isn't about poor maintenance. It's physics. Every time your door opens and closes, the spring cycles. Over 7 to 9 years, that's thousands of cycles. Metal fatigues. Rust accelerates the process, especially in Scotland's damp climate. If your spring snapped without warning, that's normal wear, not neglect.
Occasionally a spring fails early due to impact (a car hitting the door) or extreme temperature swings. But most of the time, springs simply reach their service life and give up. That's why we recommend a professional garage door maintenance inspection every 12 months.
Here's where I'll be straight with you. A single torsion spring replacement runs between £150 and £250 for parts and labor, depending on spring size and your location within Scotland. Perth and surrounding areas may see slightly higher costs due to travel time. Replacing both springs (which we recommend) costs £280 to £450.
Extension springs are cheaper to replace (£100 to £180 each) but don't expect the same lifespan. You're likely to replace them again sooner.

Labor makes up about 40 percent of the cost. Spring replacement is not a DIY job. A spring under tension can cause serious injury or death if it releases unexpectedly. We've seen homeowners attempt this and end up in hospital. It's worth every penny to hire a licensed technician.
If your door is stuck and you suspect a spring issue, don't force it. Check out our guide on what to do when your garage door gets stuck for immediate steps.
If one spring has failed and your door is less than five years old, repair might make sense. Replace the broken spring and have us inspect the other. If your door is over seven years old, replace both springs at once. The cost difference is small, and you'll avoid another emergency call soon.
For extension springs, the math is different. Replace them as soon as one fails. Extension springs wear in pairs, and you don't want the second one snapping while your door is halfway open.

When a spring snaps, your garage door becomes a safety hazard and a security risk. At Scotland Garage Doors, we offer same-day spring replacement across the region. Call us as soon as you notice your door won't open smoothly or you hear a loud bang from the garage. The longer a broken spring sits, the more strain it puts on your opener and tracks.

Springs last longer when your door stays balanced and tracks remain clean. Misaligned doors force springs to work harder. Dirty tracks add friction. Annual maintenance catches these issues before they become expensive repairs.
If you haven't had your garage door serviced this year, now's the time. Spring failure is one of the most common emergency calls we receive. A simple tune-up can extend your spring life by 1 to 2 years.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (opening and closing 3 to 5 times daily). Extension springs wear faster, usually 5 to 7 years. Lifespan depends on climate, frequency of use, and maintenance. Regular lubrication and inspections can extend life slightly.
Can I replace just one spring? For torsion springs, we recommend replacing both even if only one failed. The second spring is likely near the end of its life. Replacing both prevents a second emergency call within months and ensures balanced door operation. Extension springs can be replaced individually if only one broke recently.
How much does emergency spring replacement cost? Standard same-day spring replacement ranges £150 to £250 per spring, plus labor. If you call after hours (evenings or weekends), expect an additional service charge of £50 to £100. Early morning calls within regular business hours carry no premium. Always ask for the total cost upfront.
Is a snapped spring dangerous? Yes. A snapped spring under tension can snap back violently and cause serious injury. Never attempt DIY repair. Keep the garage door closed and call a professional immediately. Do not try to open or close the door manually, as the opener may fail without spring support.
What's the difference between torsion and extension springs? Torsion springs twist above the door center and balance weight through rotational energy. Extension springs stretch along the sides. Torsion springs are safer, quieter, and last longer. Most modern homes use torsion springs. Extension springs cost less initially but fail sooner and pose higher injury risk if they snap.
