If you've ever noticed your garage door getting heavier to open or noticed a metal coil above the door, you've spotted the springs doing the real work. Most homeowners in Hampstead don't realize they have two main types of garage door springs in use: torsion and extension. Understanding which one you have, how it works, and when it fails could save you from a dangerous situation and an expensive repair bill.
Your garage door weighs 300 to 500 pounds. Without springs, you couldn't open it by hand, and your opener would burn out in months. Springs store and release energy to counterbalance that weight, making the door feel nearly weightless when you operate it. They're under extreme tension constantly, and when one fails, the door becomes a safety hazard and a repair emergency.
Springs typically last 7 to 9 years with regular use. Once they snap, the door won't open smoothly, and attempting to use it risks serious injury or damage to your opener. This is why recognizing your spring type and understanding its limits matters before something goes wrong.
Torsion springs mount horizontally above your garage door opening, on a metal rod. They twist and wind tightly to lift the door. When you operate the door, the spring rotates in a controlled manner, releasing stored energy gradually and smoothly.
Most modern homes in Hampstead and surrounding areas use torsion springs because they're more durable, quieter, and safer than older extension designs. A single torsion spring can handle a standard residential door. Some heavier doors use two springs working in tandem for better balance.
The trade-off: torsion springs are more expensive to replace, but they last longer and provide superior door control. If you look above your door and see a single horizontal coil wrapped around a rod, you have a torsion system.

Extension springs run along the sides of your garage door opening, usually above the horizontal tracks. They stretch and contract like a rubber band to lift the door. When the door closes, the springs extend; when it opens, they compress and release their energy.
Extension springs are cheaper upfront and take up less overhead space, which is why older homes and budget installations used them. However, they wear faster and present a real safety hazard. If an extension spring snaps, the cable attached to it can whip across the garage with enough force to cause serious injury.
Many Hampstead homeowners upgrading from older systems choose to replace extension springs with torsion springs, even though the initial cost is higher. The safety gain and longer lifespan make it worthwhile.
Walk into your garage and look directly above the door opening. If you see a horizontal metal rod with a tightly wound coil around it in the center, you have a torsion spring. If you see metal coils running vertically along both sides of the door frame, you have extension springs.
Never attempt to adjust, repair, or replace springs yourself. Even experienced DIYers underestimate the tension stored in these components. A snapped spring can cause serious injury or property damage. Our team at Garage Door Hampstead handles this work safely with proper equipment and knowledge.
A snapped spring won't stop your door from opening partway, but the door will feel heavy, unbalanced, and jerky. The opener may struggle or overheat. Some doors stick in place when a spring fails, trapping your car or blocking the entrance.

What's the difference in cost between torsion and extension spring replacement? Torsion springs cost more to replace, typically $200 to $400 per spring including labor. Extension springs run $100 to $200. However, torsion springs last longer, so the total cost of ownership over time is lower.
Can I replace just one spring if I have two? No. Both springs wear at similar rates. Replacing one leaves the other ready to fail soon after. Replace both springs together to avoid a second emergency repair in weeks.
How long does a spring replacement take? A professional can replace one or both springs in 1 to 2 hours, depending on your system. Same-day service is usually available for spring failures in Hampstead.
Is there a warranty on replacement springs? Manufacturer warranties on springs typically cover defects for 1 year from installation. Ask your technician about what comes with your new springs before work begins.
Why shouldn't I replace springs myself? Springs store hundreds of pounds of force. A slip or miscalculation can cause the spring to snap, launching the rod or cable at high speed. Hospital visits and permanent injuries happen to DIYers every year.
